Your Master, Priscilla – an alcumist master, has to leave Colette alone for some time, after getting a report of some kind of serious matter from a friend. As an alcumist, Colette wants to help people out, for that Priscilla had to give her one last lesson and her old atelier in Brave City.
As you fulfill requests you meet several companions who aid you in combat, help to get semen for alcumy, and which you learn to know closer. With the outfits you collect for Colette you can trigger events and change her appearance. If you don’t want to bother with combat, just undress for a high stat boost.
The story is fairly lighthearted, everyone important has a distinct personality and since they can help gather semen needed for alcumy, you can keep Colette away from sexy times.
Anyway, you just have to swap the leader and enjoy the different scenes with people around town. Tentacle included.
