arrow that can stop Yhwach's power. Ryūken is voiced by Ken Narita in the Japanese version of the anime and by Michael McConnohie in the English dub. Sōken Ishida was the father of Ryūken and the grandfather of Uryū. He trained Uryū in Quincy abilities throughout his childhood, becoming his mentor in the process. Sōken tried to make amends with Soul Reapers by advocating a new system of response to Hollow attacks. His proposal was never accepted, and he was eventually killed in a Hollow attack due to his old age (with Mayuri Kurotsuchi being responsible for not sending Soul Reapers to save him). Sōken is voiced by Eiji Maruyama in the Japanese version of the anime and by David Lodge in the English dub. Kanae Ishida (nee Katagiri) was the wife of Ryūken Ishida and the mother of Uryū. She is of a mixed-blood heritage (Gemischt) and originally worked as the maid of the Ishida family. She befriended Ryūken since they were children and eventually developed a crush on him, although she is aware that Ryūken must marry his distant relative, Masaki Kurosaki. After Ryūken's engagement with Masaki fell through, she comforted a weeping Ryūken and eventually married him, giving birth to Uryū. However, nine years before the main story, the Quincy progenitor, Yhwach initiated the Auswählen: the process to absorb the power of impure Quincy, which took the powers of both Kanae and Masaki. Kanae, who was already weak at the time, eventually died three months later. Kanae is voiced by Mamiko Noto in the Japanese anime.

When first created, a nameless zanpakutō is initially known as an and is given to low-class Soul Reapers. Over time, from imprinting the owner's soul into it, the asauchi eventually transforms into the Soul Reaper's personal zanpakutō. As a consequence, having been a formless entity prior, the spiritual embodiment of a zanpakutō gains a unique appearance. While each one's appearance is reflection of the owner's spirit pressure, zanpakutō spirits have an additional form during the bankai state of a zanpakutō. Though they would test their owners' worth in using them, zanpakutō spirits exist to protect their wielder and would eventually cease to be if the Soul Reaper who owns them dies or uses a technique that would render the user powerless.
