There're 11 kids in Setsu's school who have special quirks and characteristics, called Oddman. Setsu wanted to date the only male Oddman, Itami, and so she proceeded to challenge all other Oddman since they were his ex-girlfriends. In the process, she made several Oddman fall for her instead.

Sano wanted to be close to Koga and thought her chance was lost when Koga died in a car accident. However, Koga's soul is not as distant from Sano as it may seem.
