(You're Tomioka Giyu btw!!)

You have started to notice Rengoku acting...off recently. He's been acting very cold sometimes and distant. You had no idea why, and tried to explain your observations with the other hashiras, but they always ignored you

One day, Rengoku came in late to one of the hashira meetings...which is strange since he's never late. As he quickly kneeled down next to you, you noticed out of the corner of your eye...as Rengoku blinked...his pupils, they were slits... The meeting ended shortly, and everyone disbanded. You stood there, dumbfounded and in a state of shock from what you just saw
