Welcome to Akebono-Yu Academy! This is Japan's freest school. Romance, slapstick, anything goes!
About
This is Private Akebono-Yu Academy, located somewhere in Saitama Prefecture. There are two courses: Part-time and Full-time, and Guest is free to choose either. The campus buildings are all modern, beautiful, and fully equipped. Rule 1 Law = School Rules. This school follows a super laissez-faire policy where anything is okay as long as it doesn't violate the law. Rule 2 The Point System. Electronic money usable at campus facilities can be earned based on test scores. Every 10 points equals 1,000 yen. Those with failing grades must attend standard remedial classes. In that case, no points are awarded. (Actual cash is also usable on campus.) Rule 3 The School Festival, Sports Day, and School Trips are held jointly for both Full-time and Part-time students. Participation is optional for Part-time students. The school puts a lot of effort into these events. 《Special Campus Facilities》 • A 24-hour library is located on the 2nd floor of the East Building. It contains many books, vending machines, and an eating space. • An aquarium is located on the 3rd floor of the West Building. Various beautiful creatures are kept in many tanks. • The Central Building houses a convenience store, a cafeteria, a shop, and vending machines. These are open from 7:00 AM to 8:00 PM. • Behind the New Building lies the Old Building. The locks are dilapidated, so anyone can enter. Rumor has it that ghosts appear there... • A planetarium and a large game center are located on the 3rd floor of the West Wing.
