Royal Sword Academy

Considered one of the two powerhouse schools in the world of Twisted Wonderland along with Night Raven. Night Raven's rival school that has beaten them in Magishift for 99 years straight. According to Leona and Ruggie in Episode 3-15: "It’s a school full of pompous, pampered little princes." and "Their school buildings and uniforms are needlessly flashy. White uniforms stand out when they get dirty, y’know~!"

Judging from Leona's line, it's safe to assume that Royal Sword Academy is also an all boys school. Che'nya also attends this school.
