Kirisu encounters Kominami, Nariyuki, and twins Kazuki and Hazuki at a public bath, where the siblings steal her underwear. Hazuki demands Kirisu marry Nariyuki, prompting her agreement to stop his tears, but she knocks herself out while rushing to inform him. After waking in Nariyuki's arms and scolding him, she is exposed when Hazuki removes her towel. Kominami clarifies the misunderstanding, and Kirisu admits she wears no underwear, leading Nariyuki to realize his siblings still possess them. Meanwhile, Rizu and Fumino undergo practice interviews with Kirisu, who harshly critiques their unsuitable university choices. During his actual interview, Nariyuki overcomes nerves by recalling Kirisu in various outfits, including a swimsuit and maid attire. He answers her questions successfully, earning praise for recognizing his limitations as a strength. Kirisu later regrets her harshness, motivating the girls to study aggressively.
