The way I see it.

My Hero Academia.
Given the recent developments in the manga, and if you haven't read it. I suggest you do since it would help you with your ideas etc.
Plus Ultra to the point that we all know everyone in this guild is a sucker for it. So I rank this first.

Magical Hero Academy. It's cool. So enlighten me.

Isekai. It's nearly impossible to pull it like Hammerman pointed out.

Shounen, you say? Where is Nardo?
