Harumi-chan's Oita · The Mysterious Guest
Wataru is stunned to find a naked girl named Harumi in his room, who quickly convinces him to let her stay by offering her body. After a series of intense sexual encounters, Harumi suddenly self-destructs, revealing that she was actually an alien probe sent to collect data on human sexuality. With the mission complete, the extraterrestrial creators appear to claim their next subject: Wataru.
