When innocence is just a facade.
Most fans can agree that seeing psychopaths in anime can be pretty fun, their unpredictable and insane nature may bring a lot of excitement and fear into a story. And they get even more frightening when they hide behind fake innocence and have a child-like demeanor. This is exactly the type of characters we're going to talk about today, so if you enjoy a little madness, you might be interested.
Cutthroat ー Akudama Drive
This sadistic murderer enjoys the sight of blood a lot, and is fascinated by its red color. Most of the time he looks pretty innocent and may behave like a child, but don't let it fool you. This seemingly carefree psychopath can sing a children's song one second and be completely unable to control his murderous side a moment later.
Power ー Chainsaw Man
Power's childish behavior is what makes this demon even more frightening. The girl is incapable of self control and is motivated only by her own desires. Power's selfishness and inability to take care of anyone else but herself makes her personality resemble a kid's one. She's eager to fight and feels the need to boast her superiority every time she has a chance to do so.
Misa ー Death Note
Despite looking like a typical pretty heartbreaker girl, Misa is not that simple. She may look endearingly naive sometimes, but it never stops her from doing whatever it takes to achieve her goal and help her beloved Light. Moreover, the girl is well aware of her innocent look, and she is no stranger to using it when necessary.
Johan ー Monster
This antagonist is extremely charismatic but is just as manipulative and dark. On the surface, he seems well-mannered and very likable, but the series is called "Monster" for a reason. Johan enjoys bringing suffering upon his prey and uses his knowledge of psychology to manipulate his victims creatively and make them do terrible things.
Esdeath ー Akame ga Kill!
Despite her delicate appearance, Esdeath is an extremely power-hungry woman, who enjoys torturing her enemies. Her cruel nature and combat abilities make her a great soldier, and her lack of empathy makes her also a dangerous one. When innocent people are on Esdeath's way, she doesn't see it as a problem: if killing them is what brings her closer to victory, then she's ready to do so.
