It's been a long time since the family was together, and now it's time for the kids to get back to school. They've been staying with their aunt in the suburbs of Tokyo for the past month, and they're getting ready to go back to their school in a few days. One of the kids, named Yukari, is a second-year high school student, and she's a member of a committee that's supposed to be discussing "beal ties" . Yukari wants to go to a meeting with her sister, but she can't because her school is so close to Yukari's. She also wants to talk to a transfer student from her school who's in the same class as her sister. She tells Yukari not to pull her hair out, but Yukari insists on doing it anyway.
