The God of Highschool is a free to read and fully coloured webtoon/manhwa, with a pretty goofy art style that goes along very well with the kind of story being told, but it can become very polished in serious moments.
The story is very basic and the title is actually very straight to the point. The main character likes to fight, meets strong people, goes to a fighting tournament, makes friends, learns more about himself, power ups at every corner, more fighting, you know the deal... but whatever, that's not the point.
I'll resume this in a nice way...
Do you like crazy over the top action packed
series? Do you like "martial arts" and Jojo stands? Do you like tournament arcs?
If yes, then prepare to ask "where the heck is the main character?" a lot, and go read The God of Highschool!
