Uryū Ishida (石田 雨竜 Ishida Uryū , rendered as "Uryū" in the Viz Media manga and "Uryu" in the Viz Media anime and Bleach: The 3rd Phantom) is introduced in the series as a classmate of the Soul Reaper Ichigo Kurosaki, who reveals himself to be a Quincy, a clan of humans which was destroyed by the Soul Reapers. Wanting to prove the Quincies were better, Uryū challenges Ichigo to see who could kill more Hollows. However, once they are overpowered and start working together, they start knowing each other, to the point they become friends. Since then, Uryū appears in the series as an ally from Ichigo, accompanying him in every fight he has.
When first introduced, Uryū uses the most common ability from the Quinces: a bow named Lone Sparrow (弧雀 Kojaku ), which has a basic form and a luminescent. Being made of free-flowing spirit particles, its size can be affected the amount of spirit particles and spiritual pressure available to it, as seen in his interaction with Ichigo during his first encounter with a Menos Grande. Additionally, he is able to use many Quincy techniques and items to augment his abilities, including some high-level techniques, which are rare enough that even Mayuri Kurotsuchi, who had studied 2661 Quincy, had never seen them in person.
As preparation for his travel to Soul Society, Uryū later masters the sanrei glove, greatly increasing his abilities via a form of resistance training. In this state, Uryū's bow is solid and covered in an intricate pattern. This new bow allows Uryū to fire several shots simultaneously. By removing the glove, Uryū attains the Quincy Final Form. The Quincy Final Form gives him a vast increase in power, enough to defeat a captain-class Soul Reaper with ease. As a result of removing the glove, however, the Quincy Final Form uses too much power for Uryū's body to handle, causing his body to block his Quincy powers completely after it wears off.
After Uryū regains his powers with the aid of his father, he uses a new Quincy cross, this one resembling a pentancle, and a variant of his original bow called Lone Sparrow on a Silver Cliff(銀嶺弧雀 Ginrei Kojaku ). Unlike his original bow, this bow is shaped like a spiderweb and can fire up to 1,200 shots at once. Uryū also steals a set of Seele Schneiders (魂を切り裂くもの（ゼーレシュナイダー Zēre Shunaidā , German and Japanese for "soul cutter"), special arrows which can be used as swords. Seele Schneiders can also be used in a reiatsu-based pentacle with the target at the center. Upon receiving Uryū's spiritual energy, it explodes, a technique called Sprenger. Uryū can also use a special Quincy foot technique calledHiyrenraku, which is similar to the Soul Reaper's shunpo and the arrancar's sonido.
