Tatsuki is Orihime Inoue's best friend and is super protective of her, and of all of Ichigo's friends, Tatsuki has known him the longest, having trained together at an afterschool karate class when they were little.

She seems to have unnatural strength for a girl and is the star of her Karate team. She even won second in a regional tournament, but only because her arm was injured from being hit by a car. Though Tatsuki eventually becomes able to see ghosts and feel hollows, she never develops any powers of her own. Even though everyone keeps the existence of hollows and their own powers a secret from her, she sometimes catches glimpses of Ichigo in his soul reaper uniform or remembers bits of memory from when she's encountered hollows.
