By request of his teachers, Ichika is drawn to an event where each of the girls are allowed to provide service for him for a limited amount of time. Initially, Houki stumbles while performing a Japanese Tea Ceremony to him, followed by Cecilia who plays billiards with him while wearing a bunny suit. Charlotte then serves Ichika some cookies while dressing as a poodle but is taken away for going too overboard on her service and Laura plays darts with him with some intimate items of hers as prizes. Before Lingyin's turn, Tatenashi appears to join the party and teases Ichika wearing a cat suit. Before the end, Chifuyu appears dressing as a maid to serve him and it is revealed that it was all part of the birthday party they had prepared to him. When asked about which one of the girls acts he liked best, Ichika chooses Chifuyu's instead, just to be scolded by them. After the party, Ichika is approached by M, who introduces herself as Madoka Orimura and is about to attack him.
