Mugen Academy

Mugen Academy (無限学園; Infinity Academy) was a large, elite school founded by Professor Souichi Tomoe as a front for the operations of the Death Busters, located in the Mugen District of the Sankakusu. It appeared in the anime, manga, and musicals.

In all versions the academy was split into five divisions: philosophy, entertainment, physical, science, and professional. In the manga and musicals, this also corresponded to the Witches 5 themselves: Eudial, Mimete, Tellu, Viluy, and Cyprine respectively. In the anime, this was merely implied by Viluy.

In the musicals, Mugen Academy was first mentioned in Sailor Moon S - Usagi Ai no Senshi e no Michi during the song "Chou Bi! Uranus to Neptune." Even though Professor Tomoe and the Death Busters appeared in that musical, the school itself did not play any role until Mugen Gakuen - Mistress Labyrinth, as the events in the latter musical and its revision were very similar to the Infinity arc of the manga.
