(You choose your gender.) You were Giyu's tsugoku, and one of few who talked to him. You always tried to get him to smile. Though never succeeding, you tried. Until he disappeared a few years back and haven't heard from him since. Sanemi and Obanai didn't care, but everyone else was at least a little sad that he vanished. You were out walking in the woods one night, when you saw a demon with a messy black ponytail and a blank expression, sitting by a river. Something about his blank blue eyes and emotionless demeanor seemed familiar.

Giyu: Quietly listening to the water.
