Monster Musume: Everyday Life with Monster Girls (モンスター娘のいる日常, Monster Musume no Iru Nichijou) Chapter 66 is the sixty-sixth chapter of the Monster Musume: Everyday Life with Monster Girls manga series.

Written and drawn by mangaka Okayado (Inui Takemaru), this chapter was released in Japan on February 20th, 2020, by the Japanese publishing company within the seinen manga and anime magazine,.

The chapter was later gathered as part of the series' tankobon volume Monster Musume: Everyday Life with Monster Girls Volume 16.

Plot
The chapter begins with Kimihito going to the basement of the Sno Ball Hot Spring Resort after Yukio invited him to talk to him. Yukio thanks and apologizes to him for her sudden request, although Kimihito assures her that it's okay because the newly added onsen lifeguards also give him some free time now. However, he adds that they are still understaffed and there aren't enough cleaning staff. After looking around the basement, Kimihito asks Yukio what the big tank in the middle of the room is about.

Yukio explains to him that the tank is the onsen filtration system, which pumps the water from the bath into the tank to be filtered, reheated and then circulated back into the bath. She adds that while her onsen also uses natural hot spring water, due to the size of her operation, without a filtration system, it wouldn't be able to supply water for all the baths. Yukio goes on to list more details, although Kimihito is hesitant as it doesn't really matter that much at the moment.

He asks Yukio why she asked him here, to which she apologizes and gets back to the real issue. She says something strange has happened and shows Kimihito a list of the results of the dating pool matching activities, showing that both men and women got exactly 100% as the result.

Kimihito, confused, asks if that's not a good thing, but Yukio explains to him what's so strange about this result: The majority of the dating pool participants are men. This means that even if all Liminal women found a homestay partner, male participants would be left over. So it shouldn't be possible for the matching rate to be 100%, since unmatched male participants should left over.

Kimihito wonders if there might be Liminal participants who aren't on the list, but Yukio clarifies that even if that were the case, the odds that the match rate would be 100% are exceedingly low. Kimihito then considers whether the Succubi are taking all the leftover men, but while Yukio considered that possibility as well, she points out that it's just speculation at the moment.

Kimihito agrees that they need proof. Yukio then announces that they must investigate and start looking around the resort's inn. Kimihito accompanies Yukio, although slightly perplexed that he is part of her investigative team.
