Shinichi Sakurai

A third year college student who is Hana's upperclassman. The two of them first met when they were members of the swimming club during high school. Most of the girls in the college are afraid to approaching him due to his scary looks. Shinichi is often annoyed by Hana's antics, especially those that come at his expense, but tolerates them as long as she is having fun during her college life. He works part time at a café near their college and is popular among the customers because of his athletic physique and work ethic.
