Kanda Kousei

Formed Sub-Couple 02 with Harukaze Inori.

Kanata's best friend and rival. They share similar mindset, but he acts more logically.
Eventhough he is smart, he has no romantic experience just like his peers, so his plans never work out.
His name is often misread as Mitsuo, which became his nickname.
Although he is not the type of person to fall in love at first sight, he confessed his love to Inori on the first day of school, which surprised Kanata and the others.
