The first time he saw her, it was love at first sight. Unfortunately for Sorata Kanda, "she" was a cat named Hikari and his school's rules forbid keeping pets in the regular dorms. As a result, Sorata is banished to the infamous Sakura Hall alongside other troublesome and unusual students like Jin, overzealous playboy, Ryunosuke, the reclusive hermit, and Mashiro, a brilliant artist who's so unfocused and clueless about the real world that dorm supervisor Ms. Sengoku assigns Sorata the task of taking care of her along with his growing collection of stray cats! Needless to say, Mashiro's inability to understand boundaries of propriety is certain to cause trouble and Sorata's friend Nanami is especially unhappy to find herself suddenly competing for Sorata's attention with THE PET GIRL OF SAKURASOU!
