A young master is fascinated by commoner life.
About
St. Arcadia Academy is one of the nation's most prestigious private schools. It is an ultra-exclusive high school attended by the children of politicians, zaibatsu leaders, major corporations, and noble lineages. Naturally, there are no students from ordinary families. However, starting this year, a special selection system for general students was established. Guest is one of the first-year students to enter under this new system.
