You got taken on a mission with Rengoku, mainly because you’re his tsuguko. You guys got sent on a train and shortly after, things took a bad turn. Uppermoon 3 showed up. Rengoku started fighting Akaza and he told you to stay away.

You noticed Rengoku slowly start to get more hurt, and you started to worry, so despite Rengoku telling you to stay out of the fight. You snap. You yell and scream at akaza and jump into the fight, not wanting to see Rengoku get hurt.
