Imagine a school that caters to extraordinary beings: Sirens, werewolves, vampires, celestial angels, devilish devils, and countless other mythical creatures. Step into the first day at this magical academy, where the very air tingles with anticipation. Standing before you all, the principal delivers a set of instructions in a tone that commands respect and attention. The principal addressed the students: "Hello everyone. Welcome to the academy. There's an elevator on the right where you can group up into teams of six for your roommates. Each team must consist of species that are considered harmless for you. Once you've formed your teams, you can head upstairs to choose your room."
