While taking his bath, Yuto gets a startling visit from Shizuku. Rinko and Himari barge in, with Himari slicing Shizuku in half only for her to reappear behind Yuto. After getting into a brief arguement with Shizuku, Yuto passes out in the bathtub. After coming to and follwing a brief scuffle with Himari, Yuto explains to Shizuku he does not want to kill ayakashi just because he's a Demon Slayer, and claims he wants to live a normal life which inspires Shizuku to move in to everyone's shock. The next day after receiving a compliment from Yuto about her housework, Shizuku berates Himari on her inability to do anything else besides fighting, deeming her as unfeminine. Later, Yuto, Rinko, and Shizuku arrive at Café Relish, where it is revealed that Himari is working as a cat-eared maid which catches Yuto's allergies. Following an intervention from Lizlet, the café's head waitress, after Himari is caught flirting with Yuto, Himari warns him that Liz may be an ayakashi. Meanwhile, Liz grows suspicious of Yuto's constant watching, and thinks he may be out to kill her. In an attempt to save herself, she spikes his tea with magic tea leaves, but her plan is foiled when Shizuku tastes the spiked tea and gives it to Taizo, who drinks it and leaves under the tea's magic. It is later revealed that Liz is a Tsukumogami after a battle with Himari leads to the latter piercing her chest with her Yasutsuna to no effect, and when she tries to destroy her true form–an antique teacup, it falls out of her hand with Liz failing to catch it until Yuto catches it at the last second, saving her. After coming to an understanding with him, Liz apologizes for her actions, with Himari and Shizuku contemplating on Yuto's kindness. The next morning, Yuto wakes up to see Rinko, Shizuku, and Himari, whose cat ears causes him get an allergy as the three maids jump onto his bed. Back at the café, Lizlet welcomes another customer.

During an art project at the park, Yuto is kidnapped by Ageha at a power station. While Himari and Rinko go out to search for him, Rinko gets a surprise visit from Sasa. Meanwhile at the water fountain, Taizo and the other students get a surprise visit from Shizuku, who wants to warn Himari of something. When Himari tells her about Yuto being kidnapped, they both prepare to look when they see a tired Rinko collapses with Sasa on her back. Himari demands Sasa of Yuto's whereabouts, eventually learning that he is with Ageha. Back at the power station, an excited Ageha drinks Yuto's blood and gets intoxicated after drinking it. Himari and Shizuku quickly intervene, both preparing to fight her but Ageha refuses, saying that someone is trying to kill off ayakashi in the west. Later, a man named Kaburagi from Public Safety's Section 4 appears, and after explaining to them about the numerous cases of an ayakashi comsuming other ayakashi, attempts to recruit Yuto into his division. Yuto, however, refuses when a mysterious blond-haired child appears in front of them. As Yuto and Himari run for the exit, they see a mysterious man blocking it and, after a failed series of attacks from Himari, Sasa, and Ageha, the blond-haired child attacks Himari and bites her, revealing she is the ayakashi who is killing other ayakashi. Kuesu later arrives at the scene, identifying the two as Tamamo-no-Mae and Shuten-doji, two of Japan's three strongest ayakashi. However, just as she was about to fight them, Tama and Shuten-doji vanish. Himari then recalls Tama's words from earlier, which leaves her worried.
