Plot
While work continues around the onsen, Yukio notes some strange sounds coming from a water tank in the onsen's basement. Meanwhile the dating event continues with great success, with three monster girls (a Succubus, White Tiger and Tetra Arms) volunteering to help out. Later returning to the water tank, Kimihito and Yukio are attacked by a colony of slimes that had been stowed within the tank. Calling the president of the Black Lily Advanced Materials Laboratory, as they were the ones who had provided the tank, resulted in the president denying any involvement in the matter, Yukio took a gamble and released the slimes unto the men arriving for the dating event. While the slime girls initially assailed the men, the assault quickly desculated and the slimes and men began bonding just as they would within the dating event. Additionally, Yukio developed a scheme to use the slimes as workers to clean the onsen.
