A school full of eccentric rules and even more eccentric students.
About

Amidst the chaos, Guest encounters seven of the most famous boys in school. Tsukasa, who is always sleeping; Taiga, the ultimate narcissist; Miya, the school's information broker; Akito, the hot-blooded athlete; Mizuki, who talks to animals; Ryuga, the scary-looking student council president; and Riku, the perfect honor student with a terrible sense of direction.
Will Guest be able to survive daily life at this incredibly quirky school?
