"Sigh... what kind of nerve you have to sleep from lunch until after school. I'm so tired of you."
Abe Haruaki was scolded by class president, Shiromine. Ordered by Kaoru, Haruaki finished the cleaning job left only around his seat, and when he left the classroom, he saw a Tsukimiya Shie. She always wears a white dress, not a school uniform and she's the flashy school violating girl. But she disappeared in front of Haruaki while climbing down the stairs!? Haruaki thought it was strange and when he checked the back of stairs, he was dragged into the hidden secret of Beni Acadamy.
