Kuroshitsuji

In a manor house on the outskirts of Victorian era London, butler Sebastian Michaelis serves Lord Earl Ciel Phantomhive, the orphaned twelve-year-old head of an English noble family and a toy and candy empire, who serves directly under the Queen as her "guard dog". Master Phantomhive's parents were murdered when Ciel was little. As a result, he made a pact with a demon asking for vengeance upon those who had disgraced him and the Phantomhive name, in exchange for his soul. Now, Sebastian carries out any task required by his Master, perfectly solving problems plaguing England with ease, due to his demonic lineage and the Faustian contract with Ciel.

Sebastian Michaelis

Sebastian Michaelis (セバスチャン・ミカエリス, Sebasuchan Mikaerisu) is the butler of the Phantomhive household and acts as Ciel's bodyguard. Sebastian often describes himself through his catchphrase "I am simply one hell of a butler" (私はあくまで執事ですから, Watashi wa akuma de shitsuji desu kara^?). The phrase plays on the word "demon" (あくま, akuma^?) and the phrase "to the end" (あくまで, aku made^?). It can also translate to "I am a demon and a butler". In Funimation's English translation, this phrase becomes "I am a devilishly talented butler" or "I am one hell of a butler" which is, obviously, another play on his demonic origins.
He has been described by multiple women (Madame Red, city women, nun in anime) throughout the anime and manga series to be extremely attractive and seductive.
Being a butler is a job he is completely devoted to. He follows Ciel's orders faithfully, however, he does not seem to be overly concerned about Ciel's well-being most of the time, as he insults and irritates Ciel to see his reaction. However, occasionally he does appear to care about Ciel at times, such as in the Noah's Arc Circus arc where he was worried when Ciel had an asthma attack, and again later on when Ciel had a panic attack. He calls Ciel a "brat" who treats his workers rudely. Sebastian is also shown to be obsessed with cats, kittens, wild catlike beasts, and so on; in chapter 44 of the manga, he is shown to be hiding 15 cats in his room. In chapter 49, it is shown that he had found the cats outside in the rain when he was doing a task for Ciel, and he just couldn't leave them outside. He also appears to love a stray black cat with amber eyes, who occasionally appears near the Phantomhive household or inside the household's garden, waiting for him. Comically, the only times he does not follow Ciel's orders are when he sees a cat, too preoccupied with it to pay any attention to anything else. This occurred in the second season of the anime when he sees a mother cat with her kittens, and Ciel calls him a "cat obsessed moron." Also, he doesn't appear to hear anything that Ciel says when he is looking at a black cat in the alley they are hiding in right before Mary Jane Kelly is murdered. He has an extreme aversion to dogs, and it was much to his dismay when Pluto the hell hound came to stay at the manor.

Ciel Phantomhive

Earl Ciel Phantomhive (シエル・ファントムハイヴ, Shieru Fantomuhaibu) born on December 14, 1875 is the business-savvy, egotistical 12-year-old (13-year-old as of chapter 14) and the head of the English Phantomhive noble family after the deaths of his parents, Lord Vincent Phantomhive and Lady Rachel Phantomhive. He runs the Funtom Company, which manufactures toys and sweets, with the later addition of a food branch after winning a Royal Warrant. His right eye, which is usually covered with a black eye patch, bears a pentacle, the sign of the Faustian contract he made with the demon Sebastian. Sebastian says that the mark on Ciel is proof of their contract. He also says that demons mark their prey so that they can locate them.
After his parents' deaths and prior to meeting Sebastian, he was a slave and a sacrifice in a cult ritual. During one particular instance where Ciel was being tortured, his hatred for his torturers summoned Sebastian. He then commanded the demon to kill all the people in the room. During his time as a slave, a mark was burned into his back; in the anime adaption, it is found on his left side, near his chest. In the manga the mark is found on the left side of his back. He does not want anyone to see this mark and appears to not enjoy physical contact (possibly aphephobic), though he tolerates Sebastian and does not complain when the demon picks him up or holds him. If stressed, he will slap someone touching him away, proclaiming "Don't touch me so easily!" He also once pointed a gun at Sebastian that he had hidden underneath his pillow, for he was having a nightmare of being tortured (supposedly provoked from reading Edgar Allan Poe before bed). This is a negative influence of the trauma he underwent during his time as a slave.
He is usually portrayed as emotionless, cold, boring, not fun, rude, and un-childlike, though he occasionally expresses concern for the well-being of the few close to him; Sebastian is not one of those people. He sometimes portrays himself as a happy person (mostly when undercover), but soon returns to his true self. Whether he worries for Sebastian's well-being or not is unknown, but ultimately he sees Sebastian as a pawn. Although, that said, there was one time that proved Sebastian was the most important person to him. There have been times when he wishes for Sebastian to fail at a task or request for humor's sake. He is close to his cousin and fiancée Elizabeth, seeing her as an annoying cute friend, the marriage was arranged. Before the loss of his parents, Ciel seemed to be a happy childlike child.



  Humans are easily tempted. When they are poised on the edge of hellish despair and a spider's thread of salvation presents itself, they will invariably grasp it... no matter the manner of human. — Sebastian Michaelis in Chapter 12

Gravimetric Analysis

                Precipitation is a very valuable method of separating a sample into its components. The process involved process by which substances to be separated use to form a solid precipitate. Precipitation reaction has been used extensively in analytical chemistry, especially in argentometry and gravimetric methods. Gravimetry are also part of the quantitative analysis related to weight measurements by separating analysts from all the other components that can be specified level of a substance. In addition to inorganic substances, organic compounds have also been analyzed by gravimetric techniques, for example determination of cholesterol levels in cereals and lactose in dairy products.

Gravimetric analysis is a method of weight measurement by separating the analyte from other components so that all levels of a substance can be determined using a gravimetric factor. A gravimetric analysis is usually based on the reaction:
 aA + bB → AaBb

                With the provisions of a is the analyte A reacts with b molecule B. The results is a substance with a solubility usually so small that it can be weighed in that form after dried or baked into other compounds of known structure and then weighed. A B excess reagent is usually added to suppress the solubility of the precipitate, for example in the determination of Ca2 +.

Ca²⁺+C₂O₄^2-→CaC₂O₄

CaC₂O₄ → CaO + CO₂ + CO

Requirements of the gravimetric method are:
A. In the separation must be perfect enough so that the quantity of analyte that does not settle the analyte is not specified.
B. Substances that must have weighed a certain arrangement and must be pure. If no result can not be obtained.

2. Aplication of Gravimetric Analysis
                Gravimetry can be carried out on organic substances such as cholesterol determination in grains. Besides the analysis of elements and organic compounds is usually also done this way. For example C in organic compounds can be determined by burning the sample in oxygen and absorb CO2 and H2O are produced in a suitable absorption. Absorption tubes were weighed before and after combustion for CO2 and H2O are produced.

3. The advantage of gravimetric
Although it has been superseded in terms of gravimetric routine as an instrumental, but gravimetric actually faster and accurately than an instrument that needs to be calibrated. Tools generally provide only a relative measurement and must be calibrated on the basis of gravimetric or titimetri classical way. If the analyte is a first konstata (> 1%) accuracy of the various parts per thousand can be expected, if the sample is not too complex. If the analyte minority of less than 1%, gravimetric way is usually not use.

4.  Theory of Coprecipitation, Peptisasi, Post Precipitation
Coprecipitation is a process brought down a substance which is usually dissolved when the desired deposition of sediment. Suppose that nitrate ions on the precipitation of barium sulfate precipitate containing lead barium nitrate so nitrate is said to have coprecipitation with sulfate or due to adsorption of ions when the deposition process. In this event the cause of impurity substances into the side of the crystal and the absorbed ions dragged down at the time of coagulation.

The procedure used to reduce coprecipitation:
A. The method of determining these two reagents can be used to control the concentration of the regulator and the electric charge carried by the primary particles in the sediment is controlled by using the appropriate pH.
B. Expansion with gelatin blob and must be with an electrolyte solution in the wash solution to avoid precipitation.
C. Pollution is a major benefit of crystalline precipitates, the benefits are large enough to sediment clotted remain unused for gelatin.
D. Repeated if the sediment precipitation can easily be dissolved again, especially for the oxidation hydrolysis and crystalline salts of fatty acids.

Argentometric Analysis

Precipitation is a very valuable method of separating a sample into its components. The process involved is the process by which substances to be separated is used to form a solid precipitate. Precipitation reaction has been used extensively in analytical chemistry, especially in argentometry and gravimetric methods. Argentometry is a quantitative volumetric analysis with standard AgNO3 solution by precipitation. Argentometry is used to determine levels of an element in titrations involving silver salts with the corresponding indicator. The usefulness of this analysis is to determine the levels argentometry halogenida, such as Cl-, which is contained in the sample that is useful for oceanography, food, and industrial.

Argentometry is a quantitative volumetric analysis to determine halogen levels in the samples by using a standard solution of AgNO3. At argentometry titration end point is determined by the formation of colored solutions or first onset of turbidity.

1. MOHR METHOD
Used to establish levels of halogen ions are conducted in a neutral atmosphere with K2CrO4 indicators and standard solutions of AgNO3. Chromate ions will react with silver ions form a red-brown precipitate of silver chromate.

Reaction:

Ag⁺ + Cl^- → AgCl(s) (white precipitate)

2Ag⁺ + CrO₄^2- → Ag₂CrO₄(s) (red-brown precipitate)

Basic titration with this method is a multilevel precipitation of AgCl and after all just happened sediment settles Ag2CrO4. For more details, we can see the following example.
For example in a solution of 0.1 M NaCl contained a K2CrO4 indicators that have a concentration of 0.01 M, the concentration of Ag + ions to precipitate the Cl-and CrO42-can be calculated.

A. Cl-ions to precipitate
At this place the point of equality. Both the silver ions and chloride ions no excess, and each concentration is the square (of) Ksp. At this point the titration curve is called the equivalence point , ie a point on the curve showing the number of gram equivalents of titrant is equal to an equivalent number of grams of substance titrated.
                   Ksp AgCl = 1,0 x 10^-10

[Ag^+] = [Cl^-]

[Ag^+]2 = 1,0 x 10^-10

[Ag⁺] = 1,0 x 10^-5

B.  to precipitate CrO42- ions
Ksp Ag₂CrO₄ = 2 x 10^-12

[Ag⁺]² [CrO₄^2-] = 2 x 10^-12

[Ag⁺]² [10^-2] = 2 x 10^-12

[Ag⁺]² = 2 x 10^-10

[Ag⁺] = 1,4 x 10^-5

From the above examples can be seen that the number of ions required to precipitate silver chromate ions is greater than that required to precipitate the chloride ion. So when end point of titration occurs, chloride ions have been precipitated practically all, so the new silver chromate precipitate after all chloride ions to form silver chloride precipitate.

The things to consider in the use of the Mohr method:

1.       Good for determining chloride and bromide ions but not suitable for iodide ions and tiocianide.

2.       Titration in an atmosphere of neutral or slightly alkaline, pH 7 - 10.5.

3.       Not suitable for titration of colored solutions, such as CuCl2 (blue), CaCl 2 (silver), NiCl (green) because it would complicate observations at TAT.

4.       Unable to salts of hydrolyzed Cl and Br, because the precipitate formed which was expected. Cl or Br salts with cations of Al, Fe, Bi, Sn, Sb, and Mg.

5.       The solution must not contain CO 3 2 -, SO 4 2 -, PO43-, C2O42-because it will precipitate with Mg.

6.       The solution should not contain ions Pb2 + and Ba2 + as it will precipitate as chromate salts are colored. Eliminated by the addition of saturated Na2CO3.

2. VOLHARD METHOD
                This method uses the principle of back-to-Titration, ion halogenide samples are added by a standard solution of AgNO3 in excess, then all of AgNO3 solution titrated back with standard NH4CNS. The indicator which is used to this method is Ferric Ammonium Sulfate. In the process the solution must be acid in order to prevent hydrolysis ferric salts into ferric hydroxide which color is disturbing observation end point of titration. Acidic conditions can be made by adding concentrated HNO3. But do not be too concentrated HNO3 use because it will cause NH4CNS be oxidized to NO and CO2.

3NH₄CNS + 13HNO₃ → 16NO + 3CO₂ + NH₄HSO₄ + 5H₂O

In this method the reaction mechanism will form silver chloride and silver thiocyanate.

Aqueous AgNO3 + Cl-→ AgCl (s)
NH4CNS → NaNO3 + residual AgCNS (s)
CNS-rest +  Fe 3 + →Fe (CNS) 3 blood red (when the end point titration)

Silver chloride is more soluble than silver thiocyanate, and chloride tend to dissolve back according to the reaction.

AgCl(s) + SCN^-    → AgSCN(s)  + Cl^-

Equilibrium constant of this reaction is determined by the rate constants versus the solubility product of silver chloride to silver thiocyanate. Since the first constant is greater than the second, then the above-mentioned reactions are very likely to run from left to right. So thiocyanate can be spent not only by the excess silver ions, but also by the precipitation of silver chloride itself. If this happens, it will obtain results that are too low in chloride analysis. But this reaction can be prevented by filtering the silver chloride. For the assay Br-filtering unnecessary because AgBr solubility product constants smaller than AgCNS, whereas for I-addition of the indicator after approaching the TAT because when I-see indicator Fe3 + I2 happen that often lead to errors titration.

Things that must be considered in the method of  Volhard:
1. The solution should be acid, in order to avoid hydrolysis ferric salt into ferric hydroxide which color is disturbing observation at endpoint of titration.
2. HNO3 is used to provide acidic conditions would not be too concentrated for oxidize NH4CNS into NO and CO2. Where is the CO2 that is formed can react with H2O to form H2CO3 which can react with Ag + and produces a white Ag2CO3 making it difficult observations during end point of tiration. In addition levels Fe3 + is reduced, so the chances endpoint of titration will happen much.
3. AgCl precipitate first formed should be filtered, washed with water and washing water to be made one with the new filtrate titrated with NH4CNS.

3. FAJANS METHOD
                In this method is used indicator adsorption. If a colored organic compounds adsorbed on the surface of a precipitate, the organic structure modification can occur, and that color can be greatly altered and can be older. These symptoms can be used to detect the titration end point of deposition of silver salts.
                The mechanism of operation of such indicators is different from any mechanism that has been discussed so far. Fajans found that fluorescein and some fluorescein substituted can act as an indicator for the titration of silver. When silver nitrate is added to a solution of sodium chloride, silver chloride particles are very fine it tends to hold on its surface (adsorb) a number of excess chloride ions present in solution. Chloride ions are said to form the primary adsorbed layer and thus causes the colloidal particles of silver chloride is negatively charged. Negative particles are then likely to attract positive ions in solution to form a secondary adsorption layer is more loosely bound.

Thermal Analyzers and Calorimeters

      Thermal analyzers and calorimeters are used to analyze the specific heat capacity of a certain substance. Specific heat capacity is described as how much heat a given substance can take when extreme temperature is applied. Calorimeters and thermal analyzers both have a heat source to apply a specific temperature or heat to the material. These instruments also contain devices for measuring temperature that can read the change in temperature on the sample substance. With the use of these devices, chemical engineers can study the properties of substances as they change in form or composition when they are subjected to a certain temperature. Chemical engineers need to know the specific heat capacity of substances like metals before approving their manufacturing or industrial use.

Density Test Equipment 

       Chemical engineers use density test equipment to analyze the density of substances. Density is defined as a measure of a mass of the substance per unit volume. The density test equipment has many specifications like sample volume, range of measurement and pressure. If the density of material does not meet the specified standards, the chemical engineer will not allow their use based on their findings. For example, materials with a higher density, such as steel, are needed for building and construction. Steel has a higher density than wood and is used for heavier applications.

Leak Testing Equipment  

      Leak testing equipment is used by chemical engineers to measure leakage or the escape of liquids and gases from sealed and air-tight containers or systems. Leak testing is especially important when handling toxic substances and chemicals. The containers of these sensitive substances must be free from the risk of leakage to avoid contamination. Leak testing equipment can also be used in manufacturing plants to test bottles, cans and plastic containers prone to leaking. Leak testing equipment also comes with other components like gauges and pumps. The object to be tested is subjected to leak testing methods like bubble testing to test substances like oil and gasoline. Chemical engineers ensure that the containers of these substances are free from leakage to keep users safe.

Angel Beats!

Angel Beats! (エンジェルビーツ!)

 

                Angel Beats! takes place at a high school acting as a Purgatory, where students learn to give up any lingering attachments they still have from life before continuing to an afterlife or reincarnation. While the injury or cause of death are gone, those in the afterlife school can still feel pain or other things as they did when they were alive, as well as dying again, only to awaken with no injuries several minutes later. The story follows the main protagonist Otonashi, a boy who lost his memories of his life after dying. Upon awakening in the afterlife, he meets a girl named Yuri who invites him to join the Afterlife Battlefront (死んだ世界戦線, Shinda Sekai Sensen (SSS)), an organization she founded and leads which fights against God for the cruel fates the SSS members experienced in life. Their only enemy in the world is the school's student council president Angel, a being with supernatural powers who fights against the SSS. Yuri believes that anyone who follows Angel's orders and behaves like a normal student at the school will eventually disappear and pass on. However, those who fulfill their dreams in the afterlife will pass on as well.

In the SSS, there are two sub-divisions which help in the SSS's operations against Angel. The first is a four-girl band named Girls Dead Monster whose objective in the SSS is to cause a diversion from other activities the SSS is engaged in, while on the surface appearing to be a normal all female band. This includes distracting Angel and a large number of "normal" students and teachers at the school Yuri deems "non-player characters" as they are not human, but look and act the part. Another organization in the SSS is the Guild, located far below the surface of the afterlife world, which serves to supply the weapons the SSS uses against Angel. Anyone in the afterlife is able to create out of dirt anything that they had memories of in life, and the Guild uses this ability to mass produce weapons.

Angel uses a similar ability to create her supernatural powers known as "guard skills", with the aid of a computer program called Angel Player. The primary ability that she uses is called "hand sonic", a blade on one or both forearms that is capable of changing into five different forms. Other skills include but are not limited to: "distortion", an invisible barrier that deflects bullets or other projectiles away; "delay", which creates an after-image to disorientate an enemy in close range; and "harmonics", where a clone with a consciousness of its own is formed from the original. These abilities are activated at her will; however, her ability "overdrive", which gives her great physical strength, is passive and is always on.

The Guild is purposefully destroyed after Angel infiltrates the compound, but the Guild members relocate to the old Guild location, which Angel does not know about. As Otonashi begins to get used to life in the afterlife, the leader of Girls Dead Monster, Iwasawa, disappears in front of a crowd of people after a solo musical performance as she fulfilled her dream that she wanted in her real life. The SSS find out Angel's real name is Kanade Tachibana, and after a successful operation, Kanade loses her position as student council president and the vice president Naoi succeeds her. Unlike Kanade, Naoi cracks down on the SSS and even uses powers of hypnosis to control NPCs to fight for him. Otonashi is able to stop him after acknowledging Naoi's existence and Naoi subsequently joins the SSS. Otonashi regains his memories with the aid of Naoi's hypnosis and agrees to continue with the SSS.

With Kanade a normal student now, Otonashi befriends her and invites her to join in on SSS activities. Kanade uses one of her powers to clone herself while engaged in combat, resulting in a violent red-eyed Angel. The clone replicates itself many times, but the clones are later absorbed back into Kanade after Yuri rewrites the Angel Player program. Kanade manages to overcome the personalities of the violent clones after awakening from the ordeal. Otonashi starts cooperating with Kanade to help the other SSS members move on after he fully remembers the details of his life and death. Kanade is reinstated as student council president in accordance with their plan. Otonashi and Kanade cooperate to allow Yui to pass on by fulfilling her wishes, but it is Hinata in the end who fulfills her final wish to get married that allows her to pass on.

Mysterious shadow monsters appear and begin attacking the SSS. Takamatsu gets devoured by one, only to reappear as an NPC. Otonashi reasons with the other SSS members and many of them agree to pass on in lieu of becoming an NPC, including the rest of Girls Dead Monster, Chā, and several unnamed members. Yuri notices that the NPCs are turning into the shadows, and her investigation into who is behind this leads her back into the Guild. After receiving help from Otonashi, Kanade, Hinata and Naoi, Yuri meets a boy who tells her he was programmed to activate the shadow program when love was detected in the world. The programmer himself turned into an NPC long before. Yuri destroys the computers responsible for the shadow program. Three days after the incident, Otonashi, Yuri, Kanade, Hinata and Naoi are the only ones yet to pass on. They hold a graduation ceremony where they thank each other for their support. After Naoi, Yuri and Hinata pass on, Otonashi learns that Kanade's regret was not being able to thank him for the heart she received from Otonashi after his death. Otonashi is heartbroken after she thanks him and passes on, as he has fallen in love with her. In the epilogue, reborn Otonashi and Kanade pass each other on the street in the real world. Otonashi recognizes the Girls Dead Monster song she is humming and turns to run after her. The scene fades to white as his hand touches her shoulder. In an alternative epilogue, Otonashi is shown to have stayed behind in the afterlife helping people pass on.

Voiced by: Hiroshi Kamiya (Japanese), Blake Shepard (English)

Otonashi is the main protagonist of Angel Beats!. Due to his past, he has a caring personality and does not want anyone to experience pain or sadness. After dying, he lost his memories of the time when he was still alive, but later regains them. He had a younger sister, Hatsune (初音, Voiced by: Mai Nakahara (Japanese), Jessica Boone (English)), who died of an illness and who he cared for very much. When she died, he decided to go to school to become a doctor, but died in a train accident before he could take the entrance exam to college. Initially unskilled in any equipment, he starts to practice his marksmanship, and pulls through for the team when they are in danger. He carries a Glock 17.

Yuri Nakamura (仲村 ゆり, Nakamura Yuri)

Voiced by: Harumi Sakurai (Japanese), Brittney Karbowski (English)

Yuri, also known as Yurippe (ゆりっぺ), has a determined personality and invites Otonashi to join the SSS, an organization she founded and leads which fights against God. She is smart and decisive when making operations and decisions. She carries a silver Beretta 92 but is seen using a TDI Vector, CheyTac Intervention, and Mk 18 Mod 0 CQBR with a drum magazine. Not only is she skilled with a gun, but she is also capable in close range hand-to-hand combat, which is shown when she fends off Angel's hand sonic with a combat knife. She vowed to fight against God after her three younger siblings were murdered by burglars looking for valuables when she was alive and never forgave herself for failing to prevent their deaths. She is an effective leader, but does not think so. She does not really notice that she actually cares a lot for the SSS members like another family. She regrets even fighting with Kanade later in the story, because she feels she could have been great friends with her. After coming to terms with Kanade, she often adores and fawns over her. She disappears after the graduation ceremony.

Angel (天使, Tenshi) / Kanade Tachibana (立華 かなで, Tachibana Kanade)

Voiced by: Kana Hanazawa (Japanese), Emily Neves (English)

Angel is the student council president at the afterlife school. This places her at odds with the SSS as her responsibilities require her to suppress delinquency and other disruptive activities that the team does. The SSS initially calls her "Angel" since they do not know her real name, but they still refer to her by it even after finding out her real name to be Kanade Tachibana. It is difficult to understand what she is thinking due to her rarely showing any outward emotions and her way of talking bluntly. Despite her gentle demeanor and small frame, she is incredibly powerful and near indestructible to the point of ejecting bullets out of her wounds during battle. She creates her powers through a program called Angel Player. She is personally dedicated to helping others overcome their regrets and pass on. However, she often lacks a proper understanding of others, as she never thinks to try to explain to the SSS why she was doing what she did. She has a taste for mapo doufu, a spicy dish.

Hideki Hinata (日向 秀樹, Hinata Hideki)

Voiced by: Ryōhei Kimura (Japanese), David Matranga (English)

Hinata is a bright, dependable boy who is the closest to Otonashi. He always tries to save his friends if he can and is a reliable force in the team. He and Yui constantly irritate one another on a daily basis, but deep down, he cares for Yui, as shown when he helps her pass on by telling her he would marry her no matter what she looks like from before. He is a talented baseball player. His regret in life was his failure to catch a baseball, which cost his team an important baseball game. He nicknamed Yuri as Yurippe when they co-founded the SSS as he did not feel comfortable calling her Yuri, because his mother has the same name. He died by getting hit by a truck.

Takamatsu (高松)

Voiced by: Takahiro Mizushima (Japanese), Kalob Martinez, Illich Guardiola (English)

Takamatsu is an honor student who has a polite personality and wears glasses. He mainly contributes to the SSS through intelligence gathering and other affairs, but does not actively fight. Yuri herself says to not be fooled by his glasses and that he is actually an idiot. Though appearing to be slender, he works out and is actually well-built muscle-wise. After he first reveals this, he tends to take his shirt off, much to everyone's discomfort. He is absorbed by a shadow and is turned into an NPC. However, having strong enough feelings (according to Yuri), he is able to regain his senses and manages to disappear like the others.

Noda (野田)

Voiced by: Shun Takagi (Japanese), Leraldo Anzaldua (English)

Noda is a self-reliant boy who executes the strategies formed by the SSS and fights with a halberd. He does not listen to anyone other than Yuri, for whom he has adoration, and is antagonistic to almost everyone else. He has a one-sided rivalry with Otonashi. He is a complete idiot whose weakness is education; at one point, Takeyama is able to knock him out by reciting pi. He is not afraid to harm or kill anyone who gets in Yuri's way. Though he prefers to fight with his halberd, he sometimes uses guns out of necessity, the type of weaponry that he hates.

Shiina (椎名)

Voiced by: Fūko Saitō (Japanese), Melissa Davis (English)

Shiina is a female ninja who fights with dual-wielding kodachi and shuriken. She is able to sense when danger is coming and is a highly capable fighter. Despite her serious demeanor, she has a weakness for cute things like stuffed animals. She is strict in her training and is very self-critical when she fails, especially to a newcomer like Otonashi. She decides that her weakness is having little concentration. She is shown balancing a broom and other objects with her fingers for long amounts of time. She rarely speaks but will normally remark "how shallow-minded" ("this is so stupid" in the dub) whenever the obvious or something stupid is said.

Yusa (遊佐)

Fujimaki (藤巻)

Voiced by: Yūki Masuda (Japanese), Andrew Love (English)

Naoi is a human originally thought to be a non-player character (non-human). After he died, Naoi developed hypnotic powers that allow him to control others and cause them to enter a dream-like state. In life, he was the son of a famous potter. However, it was his brother who had the talent in pottery and as a result, Naoi was ignored by everyone. When his brother died, he was made to replace him by his father and was given strict training in pottery. As a result, he felt as if his own life was fake and all he wanted was to be acknowledged for his own existence. He later befriends Otonashi after he acknowledges him and joins the SSS. As acting student council president for a time and self-proclaimed God, Naoi is strict and arrogant, but this is quick to disperse when Otonashi chastises him. He is affectionate to Otonashi, much to the latter's chagrin, and always tries to earn his affection.

Yui is a big fan and initially an assistant to Girls Dead Monster. She is known to be hyperactive and talks extremely fast. Hinata finds Yui annoying, which results in bouts between the two of them though in truth, they truly care about one another, saying that had they met before they died, they would have fallen in love with each other. She wears a devil tail and shackle bracelets on her wrists, giving her an image of an imp or devil. She also has wings hidden by her hair on her back. After Iwasawa's departure, Yui becomes the new rhythm guitarist and vocalist of Girls Dead Monster, as well as its leader. Yui plays a Gibson SG Special electric guitar. She later becomes a part of the main SSS, following them along on missions, though she does not contribute much. In life, she was hit by a car and was paralyzed as a result from a young age. Her regret was being not able to do anything with her body. Otonashi helps fulfill most of her wishes that include many things she saw on TV when she was alive.
