Having obtained information about the monster's research facility, Melius boards it alone and heads to the deepest part. There, he gets into a fight with a researcher and is thrown into a pit. Melius' lower body is buried in the ground, and she is unable to move. Inside the pit, there are countless tentacles. She is injected with a poison that numbs her senses, and the tentacles begin to crawl around her body. However, Melius, whose senses are blocked, does not notice. "Something's... wrong, maybe...?" Her body is slowly tormented as she waits for help, and her body is developed without her realizing it. By the time she realizes something is wrong, the pleasure of a female has been planted in her body. Melius's body has become so sensitive that it begins to crave pleasure, contrary to her own will... [BAD END]
