Shido says that even if he wants to guess, he has no idea what to do.

Looking at the clock, Kotori mentions that it is almost time for him to give Natsumi an answer. Shido says that he isn't sure as everyone did not display any odd behavior from normal, but he says that he wants to end it as quickly as possible. Kotori asks him if he noticed anything wrong with any of them that could give him a clue to Natsumi is impersonating. Later that night, at the Itsuka household, Shido is resting after an exhausting day. Shido comforts Kaguya as she begs him to find and save her sister. She continues saying that she understands why he had to lie to her about it and chooses to believe in him, as she still remembers that he is the one who gave her and Yuzuru a choice. Kaguya then begins crying, revealing to Shido that she is well aware that Yuzuru isn't on and that he hasn't found her yet. Suddenly, Kaguya covers her face on Shido's stomach and wraps her arms around him, which surprises him. She also orders Shido to pat her head, and he complies to the order. Shido promises and Kaguya rests her head on his lap. After beating Shido, Kaguya tells him to sit right next to her and states that her first order is that he not react surprised, flustered or try to stop her no matter what she does next and that he should keep it between them only.

Shido states that he won't lose and says that he will make an amazing comeback. As Kaguya manages another strike, she proclaims that he won't be able to beat her and reminds him that whoever loses has to do whatever the winner desires. Afterward, Shido goes on his date with Kaguya at a bowling alley. Misunderstanding what he means, Okamine reminds Shido of what he told her the last time they talked, presenting him with a marriage registration, much to Shido's total surprise. Okamine asks why he wanted to talk to her about his future, to which Shido replies that he wants to take it more seriously. Sometime later, Shido is talking to Tamae privately in the guidance office of their school. Shido responds that he thought that as classmates, it would be nice that they hung out sometimes, trying his best to not make the atmosphere feel awkward. Later on, Shido is with Ai, Mai, and Mii where the trio asks why he called them out together, still visibly upset and wary of Shido after what happened last time. She then asks Shido to take pictures with her, which he complies despite his embarrassment. However, a couple of bystanders notice their outfits and recognize them from a popular show and ask if they can take pictures of the two, which Miku immediately accepts. Later, Shido goes on a date with Miku as planned, with their date at an amusement park whilst wearing costumes in order to not arouse attention due to Miku's status as an idol. Shido, with this reaction, is completely sure she is the real Kotori only for her to punch him in the stomach in retaliation. Shido seemingly obliges without a second thought and Kotori nervously prepares herself, only for Shido to take off her hair ribbons, playfully refusing to give them back to Kotori.

Shido is confident she is the real Kotori, but his date tells the former to at least try confirming if it is indeed her, proposing that Shido kiss her to get a reaction. Hearing this, Kotori then suggests that Shido test if she is the real one or not. Shido wishes to find Natsumi before any more people disappear. Kotori presumes that the following days may give them a clue at the cost of more people disappearing. Shido is still wondering who Natsumi has impersonated among the 12 people in the photos. At a park somewhere in Tengu City, Shido and Kotori are on their date, discussing what happened last night concerning Yuzuru's abduction by Natsumi.
