History Characters / AnsatsuKyoushitsu

* ExcuseMeWhileIMultitask: When people try to kill Koro-Sensei he's usually doing other things, such as meticulously trim his attackers eyebrows or give a fighter jet a polish in mid-air

* DefaceOfTheMoon: Blew most of it up prior to the stories beginning.

* NotSoStoic: He tries so hard to maintain a professional demeanor, but considering the insanity of the situation he finds himself in, he can hardly go five minutes without getting visible angry.

* EmbarrassingNickname: Bitch-sensei

* DissonantSerenity: Walking up to Koro-sensei with [[spoiler: a grenade around his neck and knowing full well he is going to die with nary a change in his usual expression? Check.]] Taking down [[spoiler: an elite veteran soldier by casually walking up to him in a way he himself describes as ''as if I were walking to school'' and slashing at his neck? Check.]]

* DissonantSerenity: His greatest talent is the ability to completely hide his (considerable) killing intent, making him the most assassin-like of all the students.

* TroublingUnchildlikeBehavior: It's present for the entire class, but he's a very notable case. He's just too much of a natural at assassinations.

* NoPronunciationGuide: Many characters had the kanji for their names released without the correct reading specified for a long while. Almost all of them have had since had their readings confirmed, but some websites still list them by the translator's early guesses.

* TheStoic: It takes a lot to faze him. Mind you, he's not exactly in ordinary circumstances... So, when he does show his occasional NotSoStoic moments on his face, you know it's big.

* TheAce: The most physically capable student as well as the best in academic performance. He has the second best track record among the normal human students when it comes to threatening Koro-sensei.

* BullyHunter

* {{Keet}}:

* ActionFashionista: Very fashion-concious, loves her ''SexAndTheCity'' and teaches English to it, takes every opportunity to dress-up she can... packs weaponry and killer-intent as an assassin. That's most of the boxes ticked, then.

* GagBoobs

* MadScientist: A young, G-rated verson. Look at her smile when she's presenting her [[LaxativePrank "Victoria Falls"]].

* NamedAfterSomebodyFamous: See the matching entry at the top of the page. Ironically, he is named after the person whose death by seppuku The47Ronin sought revenge over.
** Not that ironically: the guy was considered rather abrasive and quite a nasty piece of work both in contemporary sources and since. That he got judicially murdered wasn't that much of a surprise, considering the stuff he pulled. The honour doesn't lie in the 47 defending the memory of a just man, but keeping their word and allegiance beyond his death.

The chairman of Kunugigaoka Junior High School.

!!Taiji Yoshida

* TheSociopath: He has not even the slightest shred of remorse or empathy for the students whose lives he actively tries to ruin. He also has the superficial charm and manipulation ability aspects of the disorder down pat. He also shows signs of shallow affect, such as his lack of emotional reaction to failing to stop class 3-E from winning the baseball game.
