After coming home from getting into a fight with Jun, Tomo’s father asks her what happened to her face. When she replies she got into a fight with Jun, he asks her why she lost. Tomo says there was no way she could win because she’s a girl. Tomo’s father then replies that that doesn’t matter, and that she should come to the dojo so he can beat some spirit back into her. Tomo replies that it's his fault for his stupid upbringing that Jun doesn't notice her.
