Taito is torn between having lunch with Saitohimea or eating the meal that Haruka prepared. Luckily, he is saved by a call from Gekkou as insects have invaded the school and school has been cancelled for the day. It turns out that the school is situated in a place where portals from multiple dimension intersect and that the military are in charge of the area but no one over 18 can get into the area because of a barrier. Mirai is disappointed that swim classes were cancelled due to the bugs, and forces the others to join her at the pool but Gekkou walks off to the Student Council room.
