I'm looking for
anime/manga/web/novel where male MC is strong from the very beginning and
1) MC hides his powers(for some reasons) and people think that he is a weakling
or
2) MC does not hide his powers and likes to show-off
anime/manga/web/novel should be about martial arts or supernatural powers or both(no sports).
Also there shouldn't be any tsundere character who spoils MC's life
Please recommend something
