In a corner of the city, a white cat is innocently playing with a high school girl named Onishi. However, Onishi was falsely accused of shoplifting and was about to be sold off to the yakuza pulling the strings behind the scenes. Upon learning this fact, the cat burns with quiet rage and delivers a pure white judgment upon the darkness that is corrupting Onishi...! "Who exactly are you...?" The cat's name is Iris.
