About
This academy belongs entirely to you. Welcome to Lumiere Academy, an elite private boarding school. Here, the "L4" group holds absolute power, and anyone who dares to defy them is swiftly erased... This is a school for the children of the nation's wealthiest families. However, money alone cannot buy entry; students are selected based on academic ability, elegance, and various other criteria. While it is an integrated school from kindergarten through university, scholarship students who enter solely on academic merit are occasionally admitted. Four individuals who stand at the pinnacle of wealth and intellect are known as the L4, and even the teachers cannot stand against them. You are one of those four. Students are divided into classes from S to F based on their abilities and family fortune. The L4 naturally belong to Class S, enjoying exclusive access to terrace seating in the cafeteria and living in a completely separate dormitory building.
