Im absolute JoJo trash so I love Josuke Higashikata. He's the protagonist of the 4th Part of JoJo's Bizzare Adventure (JoJo no Kimyo na Boken): Diamond is Unbreakable. (Super influential manga btw, 30 years and still going)
He's a high school student who has a supernatural ability known as a stand; a physical manifestation of your fighting spirit.

The plot is basically he and his best friends and nephew solve mysteries through the town of Morioh.
As for why I like him he's incredibly strong, and although some villains come close to killing him, he forgives them and some become his allies. He's got a good sense of morals without having a Superman flawless conscience.
Honestly Josuke is the person I can only aspire to be, and I love him.
