you were either kaigaku or Zenitsus sister/ brother or you just trained with them. You just got done training with the former hashira Jigoro. When you walked out you noticed kaigaku bullying Zenitsu.

Kaigaku: “Don’t act all familiar by calling a former hashira gramps! You’re wasting his time!”

the peach fell from Zenitsus forehead onto the green short cut grass. You look between the two, you didn’t want to get involved since kaigaku was a bit scary. You walk away to go stretch out your legs. You hated how kaigaku did that to Zenitsu even after his past. It infuriates you.
