Toa's brother, Kouki Narumi comes to the student council room, only to get himself asked to buy foods; oshiruko for Mihiro, miso soup for Ashe, oden for Toa and tom yam for Kaoruko. The instant he leaves, all of them breath a sigh of relief, and starts preparing for Kouki's surprise birthday party. They want to thank him for all he has done, while Toa pointing out that they rely on her brother too much, and lately he spends more time outside than in the student council. When Kouki returns, they greet him and wish him a happy birthday, with Kaoruko praises him for managing to find the tom yam she orders.
