Tōshirō Hitsugaya (日番谷 冬獅郎, Hitsugaya Tōshirō?) is the captain of the 10th Division in the Gotei 13. His lieutenant is Rangiku Matsumoto. Hitsugaya is the lead character of the Bleach-based film The DiamondDust Rebellion

Hitsugaya's early life was spent in Junrinan, District 1 of Rukongai. There he lived with his grandmother and Momo Hinamori. As a child, Hitsugaya had an icy demeanor that estranged himself from others, with the exception of his grandmother and Hinamori. The three were very close, and Hitsugaya was irritated when Hinamori left to join the Soul Reaper academy. Throughout his childhood, he was always aware of what seemed to be an icy presence within himself and had continuous dreams about a plane of ice. Five years after Hinamori's departure, Hitsugaya encountered Rangiku Matsumoto, then a normal, unranked Soul Reaper, in a marketplace, when she stood up to a merchant who left his change on the counter, rather than handing it to him.
That night, Hitsugaya dreamt again of the icy plain and finally met Hyōrinmaru for the first time, though he could not hear the spirit's name. He woke up to find Rangiku admonishing him for not being able to control his power, which had been freezing his grandmother. She told him that power like his needed to be controlled, and convinced him to become a Soul Reaper. With Hitsugaya's natural talent, he entered the Soul Reaper academy in spite of his age and became known as a prodigy, quickly ascending to captain of the 10th Division, ironically making him Rangiku's superior.
Tōshirō Hitsugaya is very young by Soul Society standards. Born in Rukongai, he became the youngest ever to reach captain rank. Thus, he is called a "boy genius" or a "child prodigy" by many. Hitsugaya is generally mature and serious, in contrast to his free-spirited lieutenant, Rangiku Matsumoto, although he can sometimes be short-tempered and irritable. Despite their personality differences, he and Matsumoto seem to be very close. Hitsugaya is shown to also be easily irked by others goofing off or drawing unneeded attention to themselves, as shown when he led a team of Soul Reapers into Ichigo Kurosaki's school. He hates anything that he deems childish and hates being described as something close to a child, evident in a filler episode when he meets Ichigo's sister, Karin, who pats him over the head further angering him. This is also shown more in the omake chapters, where he is repeatedly mistaken for a child, much to his annoyance.
Hitsugaya's intuition is extremely sharp, and he is the first person to correctly suspect Gin Ichimaru of foul play, though he understandably did not suspect Sōsuke Aizen of the same. He is very protective of Momo Hinamori, due to the fact that they were old childhood friends, promising to kill those who harm her.
A running gag is Hitsugaya getting annoyed when anyone refers to him by anything other than his title, Captain Hitsugaya. Hinamori has called him by "Tōshirō," ("Hitsugaya-kun" in the Japanese manga and anime) and both she and Ukitake have occasionally used "Little Shiro" (シロちゃん Shiro-chan) — a nickname meaning "Whitey" (Snowy in the English manga) in reference to his hair — in both cases without repercussion, however. In the Shinigami Golden Picture Book sketches (omakes found at the end of episodes of Bleach), Jūshirō Ukitake comically gives Hitsugaya candy and other food like watermelon which there are certain amounts of flashbacks towards because "Jūshirō" and "Tōshirō" sound similar and because they both have white hair, making them both "Shiro-chan."
Hitsugaya's zanpakutō is Hyōrinmaru (氷輪丸?, literally "ice ring", idiomatically "full moon"). Hyōrinmaru's shikai command is translated in the English anime as "sit upon the frosted heavens" or "reign over the frozen heavens" (霜天に坐せ, sōten ni zase?). Hyōrinmaru is the strongest of all ice element zanpakutō in Soul Society. Hyōrinmaru's spirit is a large, winged, Chinese dragon. Hyōrinmaru allows Hitsugaya to control water and ice. The slashes created by Hyōrinmaru gives off an immense amount of spirit power which overflows from the tip of the blade, creating a flow of ice vaguely shaped like Hyōrinmaru's dragon spirit. The dragon flies at opponents and instantly freezes anything it touches. The chain-blade also freezes anything Hitsugaya traps with it.
Hyōrinmaru's bankai.Hyōrinmaru's bankai, named Daiguren Hyōrinmaru (大紅蓮氷輪丸?, literally "great crimson lotus ice ring"), causes ice to flow from Hyōrinmaru onto Hitsugaya, forming into two large wings, a tail, guards over his feet in the shape of dragon claws, and twelve large flower petals. During one of Hitsugaya's earlier battles, the arrancar Shawlong speculates that Hitsugaya's bankai will fade when all twelve petals disappear and that Hitsugaya's bankai is incomplete due to his young age. Later during his fight with Luppi, Hitsugaya states that "even if [Hyōrinmaru is] shattered, it will reform as long as there is water present.
Hyōrinmaru's bankai has four known special techniques. The first is Ryūsenka (竜霰花?, literally "dragon hail flower"), which freezes any enemy Hitsugaya stabs, locking them into a cocoon of ice and freezing them to the core. Once frozen, Hitsugaya can shatter his opponent. The second is Sennen Hyōrō (千年氷牢?, literally "thousand-year ice prison"), which forms a multitude of ice pillars using the moisture in the atmosphere. These pillars hold the enemy prisoner for a thousand years, also freezing them.[9] His third technique, Guncho Tsurara (literally "icicle flock"), he launches a multitude of ice shards in an attempt to impale his opponent. His fourth, and implied most powerful move is called Hyoten Hyakkaso (literally "frozen sky-hundred flowers funeral"). This attack causes 100 snow flakes to fall from the sky, freezing anything they touch in a flower like shape. When all 100 flakes fall, the life of the one trapped by the attack is over.
