Nagisa x Kaede forever! Five years since class 3-E finished junior high and so far life goes well for former-natural borne-assassin Nagisa Shiota.
Nagisa and Kayano met each other at the beginning of the classes. Kayano was the one who taught Nagisa the hairstyle he always wears, but it was just because Kayano was playing her part to take her revenge later. At the end, she developed genuine concern for him. They are seen regularly together and they sit together in class. Their relationship is close and they have a very strong bond.
She is one of Nagisa Shiota 's best friends. In reality, her light green hair is dyed and is black, long, and wavy.

After seven years since graduating from middle school, she went back to her original hairstyle before joining Class 3-E.
