After hearing from Hinata's father about how he watched the sunrise from atop a mountain during high school, Aoi decides she wants to climb Mt. Fuji at night. Finding a down jacket to be too expensive, Aoi tries to borrow one from her mother, only for her to refuse to let Aoi go climbing out of concern for her safety. As Aoi becomes depressed, her father encourages her to convince her mother that she is doing something that she loves, eventually managing to get her permission.
