Kanata Nanami

Brash and impulsive, he has been friends with Tsukiko since childhood and has developed feelings for her. He does not get along very well with You. Kanata suffers from a terminal illness that leaves him in a lethargic state, which is why he often skips classes and faints without reason. However, he refuses to seek medical help and often gets into school fights that worsen his health to protect Tsukiko.
