Hello everyone, i'm looking for a manga where the MC was the son (i don't remember if the parents where heroes or something like that), but he isn't skilled like them unlike his friends on the same condition, but later, in his house he finds the ghost who his father defeated in the past and trains him. Lately, he shows his powers and has to run away.

Thank you everyone!
