مایتاکای کیونییومی

Student teacher at Risa and Ōtani's school. Maitake, who prefers the nickname "Maity", he is 24 years old [he mentioned that in the Anime] and he is taller than Risa and extraordinarily good-looking. He soon acquires a legion of female fans. Gaining affection from Risa, Ōtani soon becomes jealous and quickly starts to realize his feelings for her.

Interestingly, he bears a resemblance to "Cain-sama", a character in one of Risa's favorite visual novels.
