I, Toushirou Hitsugaya, am very young by Seireirei standards. I am the youngest in generations to have become captain and is thus called a "prodigy" by many.
I am called short & I have white hair, which draw attention in the human world. I wear standard captain's clothing without any accessories. Yet I am one of the very few shinigami in the series who carries my zanpakuto on my back instead of waist.
I am generally mature and serious, but is easily annoyed when someone (especially Momo Hinamori) refers to me anything other than Captain Hitsugaya (though Hinamori has gotten away with "Hitsugaya-kun" and the occasional "Shiro-chan"). I am overly protective of Momo Hinamori, which is mildly ironic given that she is older than me and we were raised together.
I come from Junrinan, District 1 of the Rukongai. There I lived with Grandma and Momo Hinamori, and other people, who I wil not say just to keep them safe. I became a shinigami right after hinamori. I just waited a few years. I am a friend of Jidanbou, the West Gate Keeper, and was the one who taught him the "city rules".
While growing up I was a bit of a brat who liked to eat watermelons, and still do, and poke fun at Hinamori. She would call me "Shiro-chan" and I would counter by calling her "Bed-wetter Momo". (hint something) The two of us are close friends and I, despite being younger and much shorter than Hinamori, always felt that I needed to protect her.
Highly capable and knowledgable, I became the youngest of the captains within the Gotei 13.
Shinigami captain of the 10th Division.

Hyourinmaru( lit. Ice Ring) is my zanpakutō. Its initial release command is sōten ni zase (霜天に坐せ, sit upon the frosty heavens). The sword itself does not change radically in appearance upon its initial release. Aside from gaining a long chain with a hook on the tip of its hilt, an immense spirit power overflows from the tip of the blade, creating a larger-than-life Chinese dragon made of ice which makes for a fearsome opponent. Hyōrinmaru allows me to control the weather, specifically over wind and ice. Once the water of the dragon impacts on an object, it freezes instantly and the target is trapped in ice. In addition, the chain can instantly freeze whatever I restrains with it. Hyourinmaru is the strongest of all the ice elemental swords.
Hyourinmaru's bankai is called Dai Guren Hyourinmaru (Great Crimson Ice Ring). It's similar to the shikai, only it is made of pure ice and has figures resembling 3 flowers composed of 12 petals. The dragon latches onto my, granting me a pair of wings, a tail, and also covering his right hand. Additionally, being touched by the any part of the bankai or the blade will result in being covered in ice, similarly to the shikai chain's ability.
The twelve ice petals that appear with my bankai have a special significance, and gradually melt away as I use the bankai in battle. Supposedly when the twelve flower petals all disappear, my entire bankai will too. My bankai is incomplete.
