Unlike other schools, this one doesn't accept applications. It searches the multi-verse for candidates that it deems the best in respective fields of study, hobby, talent, and/or description.

After all the students arrive, however, things quickly take a turn for the worst. A mono-chromatic creature has taken charge of the facilities. The only way to graduate and get out alive...
