Cassia and the Sealed Laboratory

Cassia has just been appointed director of a research institute. While being given a tour by her junior colleague Ren, a test subject suddenly escapes, causing a facility-wide lockdown and power outage. The escaped subject emits a mysterious gas that triggers physical mutations and mental degradation in male staff, while Cassia experiences a gradual increase in sexual desire. This is a short, story-driven RPG with an erotic focus and no combat, where players progress through narrative events and exploration to uncover different endings.
