Update #1: Introducing our third character, and my favorite of the four, Belleruche Fontaine! 
One more heroine to go, Sara Su-Cheng, in the next update.
Will be releasing some promos over the course of the next several months. Or weeks. The hope is I can get all my music assets in place soon to release them. Each promo vid will feature the heroines telling you their favorite part of the University of Leuther!
