Nyarko-san: Another Crawling Chaos W
Nyaruko still wants Mahiro, as does Hasta. Cthuko wants Nyaruko, but believes both Nyaruko's and Mahiro's "first time" belongs to her. Mahiro's mother, Yoriko, puts up with all of it and cheerfully runs the house where they all live. Mahiro just wants some sanity.
