I like this manga, It reminds me a lot of Boku no Hero but in a different way and without 10 billion different characters.
However, I don't understand why people don't like MC, like, guys, he is a TEENAGER, Obviously he doesn't have super mega cool motivations and he just wants to be like "the best of all". He must be between 14 and 15, he acts according to his age, impulsive and childish.
He has a well-made childlike personality, so for me it's a 7/10. I see potential!
Besides, this would explain the fact that he's not "bad", like, he's a child??? Obviously he doesn't want to kill someone 😭 (wtf y'all is thinking??)
