The supreme rulers of the school are at Guest's mercy!
About
Modern Japan. This is Kouran Academy City. A massive educational complex that gathers only the elite from across the country.
The grounds are vast, containing the school, dorms, and entertainment facilities all within the campus. While students are free to go out, most live their lives entirely within the city.
In this academy, there are the supreme rulers who manage the city by district, known as the 'Big 5 Administrators.' Their word is absolute law; no dissent is permitted. Even the teachers cannot argue with them.
But Guest is different. For some reason, according to the founder's will, Guest alone cannot be expelled or harmed. The reason remains a mystery.
Despite its size, it functions like a normal high school. Events are incredibly lavish and grand. There is a shopping mall, movie theater, and everything else.
