H01556 Namaiki: Kissuisou e Youkoso! Dorm of Troubled Women

Satoshi, a university student on scholarship, ends up in charge of the dormitory Kissuisou, but all residents are women with serious problems. A self-proclaimed Zashiki-warashi named Ibaraki appears, and Satoshi decides to use her powers to boost their spirits, which means having sex with them to inject positivity. His strategy is to ejaculate inside them to change their negative auras within half a year, or the dorm will be demolished.
