The Anime world can prove to be horrid in many ways. A number of anime characters suffer from various mental illnesses, and the state of their mental health is often brought out by the plotlines of a number of episodes. Thus, it's not surprising to find anime characters suffering from depression continually.
More often than not, the manifestation of a character's degrading mental health is not directly apparent, yet if one follows closely, the unmissable aspects of one's mental illness come to the fore.
