Review Detail of Brontoseno in Mha: Aegis the Shield Hero

it goes downhill FOR ME when he can control everything in his "domain". FOR ME, it will be good if the mc not OP from the begining. but gradualy become powerfull and powerfull. so we can se the progress of the story and character in their daily activity. i know that it is fanfiction story. but it will be good if the story can make the reader become exited from the progres of story. thats from me!
