The time for Koyomi Academy’s event to promote the city has arrived. It’s a time that the student council needs to come together, but Ren notices that Hotaru keeps disappearing. He finds Hotaru secretly meeting with their music teacher, Mikami Satsuki. Ren is surprised at the way Hotaru is acting towards their teacher, and to make things worse, Holmes and Watson also spot them. Meanwhile, Haruto worries about J, thinking he might also feel lonely as he does at times. Not knowing how Haruto feels, J was trying to figure out if Hayakawa had Tenna’s pendant or not, and was planning to run into him again.
