Ōhashi High School Cultural Festival (Part One).The high school is undergoing preparations for the upcoming cultural festival hosted by the student council. The boys are excited to try to stack their votes towards a cosplay cafe, but classmate Kōji Haruta draws a professional wrestling theme. The class chooses Taiga to be their representative for the school's beauty queen contest. Meanwhile, Taiga tries to ignore phone calls from her father, Rikuro Aisaka, but when she discovers that her expense account has been emptied, she sends Ryūji in her place to a restaurant to talk to him. Rikuro explains that due to Taiga's stepmother being a lot younger than him, Taiga left his house because she could not handle such a lifestyle. However, Rikuro plans to divorce Taiga's stepmother in order to live with Taiga like the old days. Kōji creates a skit for the whole class to accommodate for the theme, while Yūsaku announces four prizes that will be awarded to the class with the best performance. Taiga is infuriated when she sees Rikuro standing outside her apartment, but Ryūji eventually manages to calm Taiga down and persuades her to talk to Rikuro.
