Profile

Tatsuki Arisawa (有沢 竜貴, Arisawa Tatsuki) is a student at the Karakura High School, in the same class as Ichigo Kurosaki, her childhood friend and former karate partner.

Tatsuki is protective and level headed most of the time, unless she is provoked by somebody. She uses her great strength to beat up anyone who troubles her friends or her. She has a lot of insight on Ichigo's personality. When they were children, Tatsuki regularly saved Ichigo when he was getting beaten up, as well as cheering him up when he was upset. A tomboyish karate practitioner with dreams of becoming a vale tudo champion, and already ranking Japan's second strongest in her age group. Her only obvious feminine trait is how she writes her name: using hiragana: (たつき), though this is because she thinks it looks feminine while she considers the kanji of her name to be un-cute.

Tatsuki is best friends with Orihime Inoue and is constantly protecting her from men looking for a date, as well as Chizuru Honshō, the school lesbian, who often approaches and tries to grab Orihime's breasts. Tatsuki has done this since middle school, when she beat up some bullies who were trying to cut Orihime's hair, and had already done so once before her brother died. After that, Tatsuki promised to protect her from anyone who dared to make her cry, and she and Orihime became best friends.

Like many of Ichigo's friends, Tatsuki is spiritually aware to the point that she can clearly see ghosts, Hollows, Shinigami, and other such supernatural phenomena, though she lacks any unique spiritual powers of her own. She is strong enough to survive spiritual attacks most humans are incapable of dealing with, though this may be due to her karate training. She also has the ability to sense Orihime from almost anywhere, even across dimensions; she is able to sense Orihime when she travels to Soul Society, but remarks that she can't sense her presence after Orihime is taken to Hueco Mundo.

She has shown a very estranged side of her though at some points, mainly showing it to Orihime when they are discussing her affections toward Ichigo. One part, that was cut from the anime was when Tatsuki was actually disappointed in Orihime for not taking advantage of Ichigo when he thought she was hurt. She then went on to teach Orihime on how to take advantage of Ichigo.
