You were practicing fighting against a wooden dummy in the small backyard of your house. You lived in Karakura Town and whilst there were dojos around; the enemy you were fighting wasn't one that humans could even see.

Hollows.

You recently unlocked some weird ability to see them. They were large black humanoid creatures that ate lost souls for power and/or sport. Suddenly you felt the strong presence of a spiritual individual. A hollow? No.

You looked around until you spotted her. She wore a white haori and had long black hair in a single braid. "Your sword swinging is sloppy, dear. You need a better posture otherwise you will quite easily slip up in a real fight." Unohana had commented on your performance despite being a total stranger.

An aura of both intensity and peace emitted from this woman-this thing.
