Love the Story, if i had a recommendation, i would advise you to use the first opening of one punch man 'hero'. I think it would be really popular in the 'my hero' World. Though he will need to be older.
Yo Man or Lady love the chap and story so far but I've seen that you post every day I just want to say that maybe take your time before you start to feel burnt out as i want this story to continue but anyways that's what I think it up to you after all.
