It's a tearful day when Oishi's father, Ryuzu, gets a new job and tells Oishi they must move away.
During class, Oishi's father enters and announces that Oishi must move away and will not be able to communicate or visit her friends easily. Oishi and her friends don't want her to move away and thus she decides to have her friends battle her father (as her doing so would be considered dishonorable).
