List RulesVote up the anime characters whose mental instability you find most fascinating to watch.

Are you tired of watching anime where characters make rational choices based on healthy mental functioning? If so, you might want to check out some shows that feature mentally unstable anime characters. 

What makes insane anime characters so great is that they throw predictability right out the window. Characters with antisocial personality disorders, a condition that pops up frequently amongst anime villains, don't respond to situations the way you expect them to – building suspense and keeping you guessing about what's going to happen next and what's motivating them. Other characters with more common psychological symptoms like anxiety can be intensely relatable. 

Note: "Crazy" anime characters aren't always portrayed in the most sensitive or realistic of ways. While these characters are engaging, they're often based on harmful stereotypes. In real life, people with mental illnesses are actually way more likely to be victims of violence than to act violently themselves. That's not the case in anime.

    Future Diary's Yuno Gasai is one of the most notorious crazy yandere in all of anime. On the outside, she seems sweet, albeit a little clingy. The protagonist Yukiteru quickly realizes that her clinging is actually closer stalking and that her love looks more like violence.

    Why is Yuno like this? Most people think it's due to her childhood, which involved being severely abused by her parents.

    Midari Ikishima is a third-year student at Hyakkaou Private Academy, Kakegurui's gambling school. There, her mental issues are on full display. She's a compulsive gambler who doesn't keep track of her earnings.

    Plunging herself into financial ruin would be bad enough, but Midari isn't satisfied with that. No, she needs her own life to be in peril, even if she gets nothing out of it. For example, her masochistic desire to "feel alive" leads to masturbating while holding a gun to her own head.

  • Higurashi: When They Cry is a show about a town besieged by a contagious mental illness that drives its sufferers to commit acts of unspeakable violence. With a premise like that, it's hard to choose just one character for this list – but Shion Sonozaki's dramatic mental breakdown really makes her stand out.

    Shion is in love with a boy named Satoshi. When Satoshi disappears, Shion blames the powerful families who control their town. Her rage combined with a demonic personality that she develops to deal with her grief results in an explosive mental breakdown where she goes on a killing spree.

  • Himiko Toga only appears briefly in the My Hero Academia anime, but it doesn't take long for viewers to deduce that she's super unbalanced. When first introduced to the League of Villains as a potential new recruit, Himiko claims that she wants to kill Stain, that she wants to become Stain, and that she loves Stain.

    Why? Because according to Himiko, life is "hard to live" and she wants to make it "easier to be alive." These are not the words of a mentally stable person.
