Hero are still so weak even if season 4 end . How long he take to become powerful hero season 10 or 15 ? He is the one of the weakest hero in the academia. And in this series every single character have its own back story line which take almost 1 episode & only 10 % have action . Such a boring anime this is. Please make the powerful so he can stand on in front of powerful enemies and get slightly reduce storyline of every single character otherwise it get boring soon.
