Kotarou Yanagi
A second year St. Marie Bell Student. He is somewhat dense when it comes to romantic feelings and plays along innocently when flirted with—much to the annoyance of Nanami. He is really good at all kinds of housework, and is a part of the Handicraft Club. He is said to be the number one ideal husband at school. He is also a member of the "Silver Maidens" club.
