 If you liked Onanie Master Kurosawa |  ...then you might like Mob Psycho 100 |
Another coming of age drama centered around a loner type protagonist. However, unlike in Mob Psycho, you watch what I can describe as an inverted Mob, in which he begins as a character who believes in nothing but the bad and/or pointlessness of human relationships. Not for everyone, but if you're looking for a more heartfelt coming of age story than say, Eva, then this is worth at least reading the first 5 or so chapters to feel it out.
