SSA is the most prestigious boarding highschool in the country. The only catch is it lasts five years instead of four. The initials stand for Smithsonian School for the Arts. Normal, right? It's all just a cover. The real SSA is unknown to anyone but those who go there. The fifth year is just full of "Extracurriculars" as they call it there. Their initials? School of Sexual Arts. Crimson Noka was just a girl, who excelled in middle school and got into SSA, thinking it's just a prestigious school. It's prestigious, all right, by not in the way she thinks. But once you're in this school, you only drop out if you drop dead.
