Sensei has met Chika at the shopping mall, just as always, and she behaved a lot calmer, thanks to the conversation they've held in the school cafeteria. At that day, however, Chika visited the mall as a customer, accompanied by Yumi and Chinami.
Chika wished to buy herself something fancy, what could make her feel more desirable. With that in mind, the two made their way to the changing room.
