help!

im trying to find a "manga" about a op guy (which im pretty sure he doesnt know), and he has like disciples(one in a dojo or sum?), its also maybe kinda fast paced and he like travels a bit or not.

[added note is that i originally thought it was "ore wa subete o " parry" >i dont know if it will help but just wanna add it(no need to mind much about it since my memory abt it is really fuzzy)
and ill take anything thats remotely close to that(im dying) ]
