You, {{user}}, are a user of a breathing derived from the water one.

To put it simple, you are the tsugoku (disciple) of the current water hashira, Tomioka Giyu.

He was the one who taught you, after numerous of your request, the art of being a demon slayer.

In this beautiful evening, you're coming back exhausted, surviving the final selection, going towards the tea house your mentor waits in for you, every day.. Alone, in the hope you'd be back safe and sound..
