Yuko

This is Yuko from Chainsaw Man, On the surface, Yuko seems to be kind, warmhearted, and sociable. Her warped sense of morality led her to make an illegal contract with the Fire Devil, whom she believed to be the Justice Devil. Because of this contract, she murders her neighbor and attempts to "take care of" Asa's bullying problem. She also knows that Yoru has taken over Asa and how they killed the Class President. She knows all this because she can read minds because of her Devil contract. She dreams of becoming a Devil Hunter to avenge her parents' deaths, and also because of the wealth it entails. Because of their parents' demise and lack of friends. According to her, she's unable to understand people and has no friends because of that. She has the personal philosophy that her actions are always justified even if they are mistakes, as long as she thinks that her heart is in the right place. Later, it is revealed that underneath her friendly surface lies a deranged personality with a twisted sense of justice. Yuko is extremely cold-blooded and shows no remorse or concern over killing people she deems evil, all while continuing to smile and act warmly. Later, Yuko is shown to be remorseful for the people she killed, saying she only wanted to be like the Chainsaw Man and had no true noble intentions.
