Yuya encounters Neko that night who asks him how he feels about Mitsuki and Yukina. Unable to get an answer out of him, she puts Yuya into a kind of hypnosis she learned that causes him to be honest with his own desires and how he really feels. By morning when Shotaro cant wake Yuya everyone comes in until he wakes up. He then blurs out that Mitsuki is really cute, and proceeds to grope Yukina causing her to slap him. Neko explains the short term hypnosis she put him under which causes Mitsuki to blush thinking of what he said. Neko tells everyone that if anyone wants to ask him something they maybe will get an unexpected answer. As the day goes on Yuya is sick with a fever, and Mitsuki thinks over what Neko said. Yukina later comes over and talks to Yuya where he tells to her disappointment that she didn't have to change for him. Yukina also lets Mitsuki know she knew about Hiyori but never said anything. Hiyori sees the chance to be "lovey dovey" after Yukina leaves but Mitsuki refuses due to his fever. Yuya meanwhile, is in his bed unable to sleep as he thinks of both Yukina and Mitsuki. He then awakens and bursts through Mitsuki's door causing her to be embarrassed that she is still half naked. To Mitsuki's surprise, he says that she should stop wearing the "scary panties" (belt) which causes her to kick him out. Hiyori then tells Mitsuki that the heart is full and leads her to the now open golden gate. Hiyori disappears behind the doors along with the belt on Mitsuki but not before saying she wants to be reborn as the child Mitsuki and Yuya have. The next day while leaving for school, Mitsuki finally refers to Yuya as "*Oniichan" rather than "you" or "him" in reference. As the credits roll Mitsuki goes to where she was first possessed by Hiyori only to find her again. Hiyori takes her through the golden gate she went through only to have it lead to a floating island with a sign saying "2F" on it. With another golden gate visible Hiyori places the belt back on Mitsuki. Hiyori then explains to her that she made the belt 30% more sensitive to make their hearts throb faster together causing Mitsuki to cry out in embarrassment.
