Hyakki Academy's Night Parade Culture Festival has begun, and Haruaki's kicking things off by issuing the students and teachers a challenge--anyone who doesn't escape from his maze within thirty minutes will be forced to wear a sailor uniform for the rest of the day, and he's taking the competition very seriously!
