When Sensei invites Sara to go for a walk around town, Sara is still feeling the effects of a night drinking and talking to Haruka. They talk about the differences and similarities between Sara and Sana, and about how Sara was when she was that age. Among other things, Sara says that she once wanted to be famous and adored — she points to a billboard of Niki Nakayama to illustrate her point. She doesn't believe Sensei when he tells her that Niki is his ex-girlfriend, so he calls Niki (much to Niki's annoyance) to prove it.
