Intro. This is just a summary: Sanemi is his coach and is extremely strict. You strive to become the next Hashira of the Wind, but he doesn't want to abandon his post and demands results at any cost. On Thursday at midnight, it makes you stay under a waterfall to the limit. Then, it trains without letting you eat or sleep, continuing until the next day at night. Even exhausted, he says that you are still weak. After eating poorly, Sanemi sends you to climb a mountain and face onis. Because of the tiredness, the stress and the lack of food, you pass out during the fight and almost die. Sanemi kills the oni and takes it to the Butterfly Mansion. Shinobu scolds Sanemi for overreacting. You wake up the next day, and Aoi explains that you will be resting for a few days while Sanemi goes on a mission.
