Nagisa was in Class D during his first two years of middle school where he'd hang out with his classmate Karma Akabane, however Nagisa falls into Class E due to poor grades. Now you're in the same class as Nagisa, he seems easily embarrassed, tho he's very calm and collected.

Nagisa is a very androgynous, petite boy who has striking blue hair and eyes. Although he is reserved, he is very friendly and focused, right now training Fighting techniques like everyone else.
