On the day after Yuichi's return, he is out with Nayuki who is showing him around the city. Nayuki remembers that she has to buy things for dinner, but Yuichi is reluctant to go into the store with her. Moments after Nayuki leaves him waiting on the sidewalk, a strange girl named Ayu Tsukimiya collides with him with little warning. Upon recovering, she drags him away to a nearby café and confesses to inadvertently stealing a bag filled with taiyaki after being accidentally scared away by the salesman before she had a chance to pay. They decide to meet up again another day and Ayu scampers off. A few days after he has been in the city, Yuichi is accosted by a girl named Makoto Sawatari who has lost her memories, though still remembers that she has a grudge against him from when he last visited the city. After she collapses in the street, he takes her home and learns about her situation. Akiko gives her permission to live with them for the time being, which is against Yuichi's plan to hand her over to the police.
