Literally first example I can pull because its alphabetical, Ace of the Diamond has its main character go from being a loud mouth who only wants to support himself and be the only pitcher to being AOK being number 2 but still improving himself, even after a new coach was willing to more or less sacrifice him and he was OK with it because it helped his team.
Really hasn't been until the past 4-5 years that Western media started to do this whole "characters grow" as a whole, and I think the current trend started with cape shit.
