冴木 紬

"Mashiro-chan is frightened, but she's not a coward. She's a hard-working girl who hates to lose."

Enishi's younger brother. He was born with a weak heart and often misses school, but he still has many friends of both genders: maybe he inherited friendliness from his older brother.

The fact that he admires Midori, is liked by animals who he is friends with, and is even able to communicate with them is due to his family's demon exterminator blood. He prefers being with his siblings and says that Mashiro is his "older sister."
