Cassia and the Sealed Laboratory

Cassia, who has just been appointed as the new director of the research institute, meets her junior colleague Ren and is being given a tour of the facility. However, a test subject suddenly escapes, causing the entire institute to be shut down—and even the power to go out... Due to the gas emitted by the escaped test subject, men’s bodies mutate and they lose their sanity, while Cassia, a woman, finds her sexual desire gradually increasing.​
