Mariana Tozawa, the young leader of the Tozawa conglomerate and a researcher of magic, has protected Raccoon Town by fighting evil as Sailor Lily. One day, she discovers an illegal magic trade operation and engages in a fierce battle with a gang, only to learn that behind it all is Rai, the former research advisor of Tozawa Manufacturing whom Mariana had previously fired. Seeking to recreate the chaos that once plagued Raccoon Town, Rai decides to destroy Sailor Lily. He sneaks into Lily's home and executes a despicable plan: using a magical plant, he implants a seed into her anus, robbing her of bodily control. Invaded through her anus, Lily falls under the domination of the plant's tentacles, gradually consumed by overwhelming pleasure. Can she overcome this ecstasy and reclaim herself?
