Hiyori collapses onto Yya revealing Mitsuki who calls him an idiot and asks what he is doing. Before he can ask her more about it she collapses again saying it wasn't her. Mitsuki embraces Yuya while calling out to her mother when he goes to help her out, he then puts her into bed to rest from being sick. The next morning, Hiyori is relieved that Mitsuki is okay however she sees that she still is not fully recovered. Yuya meanwhile, asks Yukina for advice but doesn't use Mitsuki's name. He gets some helpful advice from her but comes to the wrong conclusion about why she is wearing the "scary panties" (referring to her belt). While walking home from school, he gets the chance to talk to her again. Yukina asks Yuya why he thinks she changed from being a tomboy in the past to how she is now but is interrupted before she can get an answer from him. When he gets home Mitsuki, who is possessed by Hiyori while the real one is sleeping says to Yuya that there is something she needs to tell him. Yuya confusingly thinks on what it could be that Mitsuki wants to tell him and is unsure how to react. While taking a bath, Hiyori (possessing Mitsuki) is hesitant but determined to have sex with Yuya thinking that at the rate things are going with Mitsuki she will never get to heaven. She then goes into Yuya's room half naked to his embarrassment, but doesn't know how to bring up the topic and stalls long enough for the real Mitsuki to wake up and protest against what Hiyori is doing. Hiyori puts Mitsuki back into her own body out of embarrassment just as Yuya tells Mitsuki he is okay with her liking girls. He is worried about the belt though and again misunderstands why he sees her with Hiyori, making Mitsuki wonder how he came up with such a crazy conclusion. Yuya tells her he is okay with her wearing the belt but wish she would be more careful. Mitsuki cheers up from his overall kind words, but kicks him out when he motions to her being half naked. The episode ends with Yuya reading a thankful note from Mitsuki saying she is going back to school.
