The game follows our protagonist Luciely (Name can be changed), who is pondering on a journey to unravel the "mysteries of the world", or at least that's what she wished, till... Luciely finds out that she's blessed with a very unique ability called "DressOver" that allows her to change into certain forms, such forms are unlocked in two ways; Consuming a being's soul, or draining its essential energy. Mavilus (name can be changed) soon teaches Luciely how to do both ways, consuming the soul has to kill the being, but draining the essential energy can be obtained through sexual acts, as long as the "essence" of the being is "inserted" into Luciely somehow. Then she decides to dedicate herself to studying this new skill of hers, which until then is something unique and exclusive only to her in the world!
