No, Ichigo's mother, Masaki Kurosaki, is not a Quincy.
Masaki was a Shinigami who belonged to the 10th Division of the Soul Society. She was a powerful Shinigami with exceptional abilities, including the power to use Kidō and Zanpakutō.
Evidence supporting this claim:
- Masaki's Zanpakutō: Masaki possessed a Zanpakutō called Shikai: Tenken that could transform into a gigantic, multi-bladed weapon. This is a distinct feature of Shinigami, not Quincy.
- Masaki's powers: Masaki displayed the abilities of a Shinigami throughout her life, including the ability to use Kidō and fight Hollows.
- Masaki's background: Masaki's family background is not related to the Quincy. She had no known connections to the Quincy clan or their traditions.
It is important to note that Masaki had a complex past and was involved in a conflict with a powerful Quincy named Yhwach. This interaction led to her death and ultimately influenced Ichigo's destiny. However, this conflict does not make her a Quincy.
