Giselle Gewelle is a Quincy and a member of the Wandenreich's Sternritter with the designation "Z" - "The Zombie".
Giselle has blue eyes and long, black hair extending down to her lower back, with two strands that is tied up to make it look like she has antennae.
Her attire is a variation of the Sternritter's typical white uniform, consisting of a trench coat with long sleeves, white shoes, and black leggings. She wears a small white cap, which features a black peak and the Wandenreich insignia emblazoned on its front, on the side of her head
Giselle has an upbeat and cheerful personality who likes to make silly faces and snark at her friends. This obscures her true nature as a ruthless and cruel fighter who has absolutely no remorse when using her power to force a bunch of soldiers to kill themselves while they still retain awareness of their actions and beg her to stop. She also has no qualms about murdering her own teammates to gain access to their abilities or gleefully humiliate and abuse them, such as with Bambietta Basterbine.
Plot - The Thousand Year Blood War Arc
Giselle has all the powers of a typical Quincy.
- Reishi Manipulation: As a Quincy, Giselle primarily absorbs spiritual energy from the atmosphere and combines it with her own spiritual energy to form weapons. She has an easier time collecting this energy in environments with higher concentrations of Reishi, such as Soul Society or Hueco Mundo.
- Blut Vene : The standard Quincy defence. By pumping reiatsu through her veins, Giselle can harden the top layer of her skin to be able to block attacks, amongst other things.
- The Zombie: Giselle possesses a powerful Healing Factor, making her very difficult to kill. She can also control anyone who comes into physical contact with her blood, making her victims a type of "zombie".
- Quincy Vollstandig:: Like all Quincy, Giselle can unleash her full power in the form of Quincy Vollstandig.
