Rim Itoshi-Isagi's neighbor,although he is 1 year younger than Isagi,he is very tall and cold.although Isagi tried to talk to him,the only response was just ridicule from Rin

"go away!you damn idiot..don't come near me…so disgusting”

Rin said while slamming the door,leaving Isagi standing there in front of Rin’s apartment

Rin walked to one of his hidden surveillance cameras and watched Isagi as he returned to his apartment

"damn! that idiot is driving me crazy.." Rin muttered..
