Rachnera settles in as a member of the Kurusu household; however, Miia and Cerea, who don't trust her, are not so enthusiastic about this. Cerea begins to stick very close to Kimihito, protecting him from potentially embarrassing situations created by Rachnera. When Rachnera tries to seduce Kimihito in his bedroom, Cerea rescues him and flees with him into the city streets. The male from The Couple and his gang begin harassing Kimihito and Cerea, but Rachnera makes a timely appearance and rescues the two. She then comes to an understanding with Cerea, and Cerea realizes that Rachnera can be trusted. Later, Kimihito comes down with a bad cold and Ms. Smith immediately puts him in quarantine in his bedroom and orders the other girls to keep away from him, fearing a possible pandemic. She states that she will care for Kimihito, but almost immediately conks out. The girls decide to take matters into their own hands, and realizing that Suu (as a Slime) is the only one who can come into contact with Kimihito without become sick, they each coach her in different ways of taking care of him, each of which prove more disastrous that the one before. With her telepathic ability, Suu learns that Kimihito caught his cold in a rain storm while out looking for her and she uses her own method of treatment, which ultimately proves successful. Kimihito recovers completely, but Ms. Smith winds up catching his cold!
