Sakuta from the other possible realm sends a message through Ikumi that reads, “Find Touko Kirishima, Mai-san is in danger.” After seeing this message, he tries contacting the Miniskirt Santa, who claimed to be Touko Kirishima. A few days later, he receives a call from her saying that she can meet on December 2nd… which also happens to be Mai’s birthday.

Sakuta dreams that on Christmas Eve, when he is meant to have a sleepover date with Mai, he instead goes on a date with a student named Sara Himeji from the cram school where he works. The Sara in question has the same dream as Sakuta and goes on to confess that she has her own Puberty Syndrome. However, she says that she does not want her Puberty Syndrome to be fixed.

Sakuta warns her that this is a dangerous move. To which she retorts to provoke him, “What should I do so that I can love people. Like you do, Mr. Sakuta?”
