Mitsuhashi High School Cat Club

When the club door is opened after school, the four cats have been awaiting for them! The stray calico cat who absolutely adores his owner, Miisuke. The tsundere cat who acts like a queen, Maria. The cowardly little kitten, Sasuke. The chubby mafia boss-like cat, Oyabin. The four cats have been kept well, pampered, and adored... in the Mitsuhashi High School Cat Club!
