* BadBoss: Oh yes.

* EvenEvilHasStandards: [[spoiler: In the anime, when it’s discovered that Satou doesn’t actually care for the plight of their fellow Ajin, all but Tanaka abandon the Resistance. A few even decide to join Kei and Tosaki in their efforts to stop Satou.]]

* DebtDetester: [[spoiler: After being rescued by Izumi he agrees to help her as he doesn’t want to indebted to her]]

* EvilCripple: He is born with a crippled leg that did not heal even after reviving, necessitating him to use a crutch to walk.

** Despite all his talk of not caring how many people Sato kills, [[spoiler:when push comes to shove and Kei is given a free ticket to escape from Japan and live a peaceful life overseas, [[WhatYouAreInTheDark he ultimately can't bring himself to do it]] and joins up again with the others to stop Sato from having his way.]]

* DebtDetester: [[spoiler: After being rescued by Izumi he agrees to help her as he doesn’t want to indebted to her]]

* TokenGoodTeammate: In the manga, Tanaka is the only member of Sato's group to have genuinely sympathetic qualities, [[spoiler:and likewise is the only one to pull a HeelFaceTurn]].

* UndyingLoyalty: To Sato for freeing him from an endless cycle of torturous deaths at the hands of a weapons testing facility. [[spoiler:Even when he learns Sato doesn't give a damn about Ajin rights, which was the while reason he joined up, he chooses to stick around]].

* TheBusCameBack: [[spoiler:Comes back into the story after Kou rescues him from the steel drum he was trapped in.]]

* BornLucky: Considering that [[spoiler:he isn't an ajin, it's kind of crazy that he lasted as long as he did.]]

* OOCIsSeriousBusiness: Kei constantly gives Kou shit for his BookDumbTendencies and expresses visible annoyance on the rare occassion that Kou brings up a good point. In the climax of the series, however, [[spoiler:Kou comes up with a genuinely good idea that would allow them to finally defeat Sato[[note]]That being to break open a telephone pole and to drop Sato's severed arm into it, as telephone poles are hollow in the inside and have just the right diameter to fit Kei's plan[[/note]], prompting Kei to yell "'''You are the man!'''" At this point the guy is so at the end of his rope that he doesn't even bother with his normal InsufferableGenius attitude.]]

* DecoyProtagonist: He is initially set up to be TheDeuteragonist to Kei's protagonist. However, little ways into the story, Kei leaves him behind for his own safety, at which point he completely disappears from the story for a long while. [[spoiler:Even after returning, he is still more of a secondary character.]]

* LoveIsAWeakness: "Let your heart guide you and your body will crumble". [[spoiler: Kei seems to notice this within Tosaki, believing it to be ''his'' advantage and Tosaki's disadvantage.]]

* SuicideDare: To Kou.

* TheWatson: Given that Japan is pretty far behind the US when it comes to knowledge on ajin, Kouma's misconceptions on how IBMs work is what prompts Ogura to deliver some exposition on them.

* AdaptationalHeroism: In the anime, he's a genuine believer in the Resistance's supposed cause. In the manga, however, he's every bit as bloodthirsty as Sato and simply enjoys causing chaos for its own sake.

* LaughingMad: He laughs maniacally when stressed, such as when the group is preparing their attack on the pharmaceutical company.

* HiddenDepths: [[spoiler:He's actually a human who joined the resistance because he and his brother Takashi wanted to mess stuff up.]]
* ScarsAreForever: He has a scar across the bridge of his nose. As an ajin this wouldn't be true, but he hasn't died since he got it. [[spoiler:It's actually because he ''isn't'' an ajin.]]

%% [[caption-width-right:250:some caption text]]

* TheFatalist: He's a strong believer in predestination, and according to his theories ajin are the only ones capable of determining the future of themselves. [[spoiler:Though he does seem to question his beliefs somewhat when he ultimately survives.]]

* DirtyCoward: He kowtow's to the (supposed) demands of Sato's group the moment his own life is threatened.

* TokenGoodTeammate: In the manga, Tanaka is the only member of the Ajin resistance who genuinely believes in the cause.

* ParentalNeglect: She doesn't seem to visit Eriko often nor does she do anything about her son being an Ajin other than disown him. [[spoiler:The latter is at least justified, since she can't defend him without getting in trouble]]. In the manga, it's suggested that she doesn't see Kei much either.

* ItsAllAboutMe: This man doesn't care about the conflict between Ajins and the Government. All he looks after is his own life, his work, and whether or not can he smoke his cigarettes.

* EasilyForgiven: It takes all of a few hours to start getting chummy with the man who tortured him. Considering that he's later shown to be a diehard fatalist, it's likely that Ogura doesn't even see the point of getting angry at someone.

* BigDamnHeroes: [[spoiler:He shoots Sato in the chest with a sniper rifle just as he's making his getaway in a helicopter, causing him to fall back to the ground and allowing him to ultimately be captured.]]

* ScrewThisImOutOfHere: After [[spoiler:being defeated by Sato at Forge Security]], Manabe decides that enough is enough and to get away from things while he still can. [[spoiler:He ultimately [[ChangedMyMindKid changes his mind]].

* EasilyForgiven: It takes all of a few hours to start getting chummy with the man who tortured him.

[[folder:Sokabe]]
!Sokabe
->Voiced by: Creator/KenichiSuzumura (Japanese), [[Creator/LittleKuriboh Martin Billany]] (English)

High-ranked member of the Ministry of Health, Labour, and Welfare, assigned to supervise Tosaki and later to succeed him as the head of the Ajin Management Committee.

* {{Irony}}: At the start of Chapter 53, he calls Tosaki out on wearing gloves during his work, saying that Tosaki is still clinging to the past. That same chapter [[spoiler:Tosaki kills Sokabe ''without'' gloves on after the latter threatens Izumi and tries to stop Tosaki from leaking the DHCC's secrets to the public.]]
* ItsAllAboutMe: In contrast to Tosaki, Sokabe doesn't give a damn about anything besides climbing up the government hierarchy.
* {{Jerkass}}: His job seems to be to constantly pester Tosaki regardless of what the situation is.
* PsychoticSmirk: As if his character design is not indicative of his Jerkass personality enough, his smirk rarely leaves his face.

* MajorMinorCharacter: She's clearly a big deal in Ajin research, but she only appears a handful of times in the actual manga.

An American biophysicist professor abducted to work for Tosaki.

* AdaptationalHeroism: In the anime, he's a genuine believe in the Resistance's supposed cause. In the manga, however, he's every bit as bloodthirsty as Sato and simply enjoys causing chaos for its own sake.

* AdaptationalHeroism: In the anime, he's a genuine believe in the Resistance's supposed cause. In the manga, however, he's every bit as bloodthirsty as Sato and simply enjoys causing chaos for its own sake.

* BoobsOfSteel: She has a notably large bust beneath her conservative clothing, plus she's an Ajin who fought off Tanaka and held her own against Kei making her one of the stronger characters in the series.

* TheCavalry: [[spoiler:They're finally deployed in the final battle agaisnt Sato.]]
* ChekhovsGun: They're routinely brought up throughout the series, but don't make an appearance until the end.

* DeathFlags: In chapter 46, he notes that he's probably going to die once he finishes his Mild Seven cigarettes and in the series' climax, he's down to his last one. [[spoiler:[[{{Fauxshadowing}} He survives]].]]

* TheSmurfettePrinciple: She was the only female Ajin in the series, [[spoiler:until Carly Myers was introduced.]]

* SenselessSacrifice: [[spoiler:Sadly, despite sacrificing himself for Shinya, the government agents still have Shinya cornered. However, his death did in fact trigger Shinya to go into an UnstoppableRage.]]

* BitchInSheepsClothing: Downplayed, but still somewhat present. Kei in the first few chapters comes across as fairly nice guy. As the series goes on, however, Kei is primarily characterized as a logically-driven {{Jerkass}} [[AntiHero who isn't afraid to throw some people under the bus]] if the situation calls for it. Though given that the first volume was written by a different writer than the rest of the series, it's more likely a case of EarlyInstallmentWeirdness.

* LikeMotherLikeSon: Kei's logically-driven nature is largely taken after his mother.

* {{Expy}}: Strictly in terms of appearance, he becomes a dead-ringer for Shotaro Kaneda from ''Manga/{{Akira}}'' due to the ''Ajin'''s ArtShift.
