Plot
It's the last day Kimihoto and the girls are working at the Inn, but unfortunately some problems have arisen. First of which are the Arachne, who after coming such a long way have decided to not participate in any of the Onsen's activities, instead choosing to stay in a large convention room for the time being. Secondly, a group of Minotaurs have been constantly asking for the sauna to get hotter, almost causing heatstroke for even Miia. And thirdly, Miia's tribe makes a surprise visit. Kimihito and Miia are pressed to figure out what to do with the enormous groups of Liminals, figuring to keep the Lamias and Minotaurs separate to conserve space. Meanwhile, Rachnera gives her report to the Arachne, planted as a sort of "Field Agent" to see if intermingling with Humans will work. Rachnera tells them to experience it for themselves, as her one voice wouldn't matter that much. After consideration, the Arachne decide to try out the Dating Baths.

Unfortunately, now this means there are three large groups of giant liminals spread throughout the baths, and Kimihito is pressed on what to do. If the Lamias or the Arachne decide to try the sauna, there won't be enough space. Luckily, Yukio returns with a plan of her own. With the help of her Salamander and Undine friends, she turns the main pool room into a Sauna of it's own, letting there be enough space for all three groups of liminals to easily move around and find new lovers. The Lamias (Miia's sisters specifically) find their own boyfriends, the Minotaurs are happy to sit in the pools with the temperature at Sauna level, and the Arachne finally begin to mingle with humans. With the last problem solved, Yukio finally lets our protagonists relax, letting them sit in the baths.

Key Events

 * More Arachne are finally seen and we get more backstory on them.
 * Although not specifically addressed, the dialogue between Rachnera and the rest of the Arachne seems to confirm that Arachne, like Lamias and Harpies, are a purely female species.
 * It is also revealed that Rachnera's original reason for participating in the Extra Species Exchange Program was to serve as her tribe's expeditionary force, finding out if Arachne can live alongside humans or not.
 * Lala makes an appearance.
 * The Lamia tribe makes a return.
 * The leader of the Arachne may be a Shotacon.

Trivia

 * In an apology to those that did not get featured within the "Onsen Arc" Okayado claims that he fit 30 Mob Characters applicants within this chapter.
 * The visual design of Yukio's Undine friend is different from the Undine that appeared in Chapter 49. Whereas the Undine in Chapter 49 possesses large webbed ears (or at least adorned by a headdress covering her ears) Yukio's friend is more similar in appearance to Dina, the Undine in Monster Musume: Everyday Life with Monster Girls Online.
 * As stated in Rachnera´s Secrets, each Arachne is born with a different pattern, and while all Arachne appearing in this Chapter have vaguely skull-like patterns like Rachnera (likely due to being of the same tribe) the details of the patterns are somewhat different for each of them.
