Nagisa is a young boy who has a crush on Hanon. After retrieving some sheet music for Hanon, he has been wooing her ever since. Unfortunately for him, the sheet music is of the tune Tarō Mitsuki dedicated to Hanon, which only reminds her of her fixation on the much more refined and older man. Still, his resilience is to be admired, and she eventually treats him better. In the manga, he says that he is two years younger than Hanon. In the end, Hanon falls in love with Nagisa and they have a relationship at the end of the manga.
