Ayano has a weird combination of being adorable attentive and also an oddball. Yuki messing with her, and she is so unaware of it. One thing interesting to note that Yuki and Masachika compliments the other say the other is better. Yuki mentioning she never beat her brother when he was serious. While Masachika mentioning how he feels inferior to Yuki. This brings the question of who Masachika really is?
The conversation really brings some insight on the Kujou's sisters' relationship. We know that Alya is beyond hardworking and has great pride on it. Masha is in the background watching her and making her she has someone to support her. So despite what her feelings may or may not be for Masachika, as a sister see is beyond thrilled he is supporting Alya. It also brings into question is Yuki doing something similar for Masachika?
Taniyama really brought the edge out. First instigating with Alya and when Masachika stepped in, things got worse. She acted like Alya was just a puppet for Masachika, which could be furthered from the truth. Curious how Alya bounces back for the challenge Taniyama dished out.
