|Portrayed By||Shion Hirota|
A weapon of the Sister's Cavalry, which serves Pendragon.
00 is their calm and composed leader. However, this is merely the role demanded of her, since she's far more frail by nature.
00 excels at reconnaissance and serving as an advance guard, displaying extreme supremacy in unexpected encounters.
However, her excessively powerful fighting strength has been called inhumane, and it isn't rare for her to be lynched and abused when she surrenders on the battlefield.
Her one eye silently speaks to that.
Like the other Chiester Sisters, Chiester 00's real world counterpart is speculated by Dlanor A. Knox to be one of Kinzo Ushiromiya's Winchester rifles. However, her real world vessel is actually one of four ceramic bunnies owned by Maria Ushiromiya.
Chiester 00 appears as young girl with blonde hair, bunny ears, and red eyes. She wears the Chiester Sisters Imperial Guard Corps uniform with black accents and has an eyepatch over her right eye. She also has the One-Winged Eagle tattooed on her right thigh. Notably, one of her bunny ears is scarred.
Chiester 00 serves as a dependable leader and is typically very serious.
Alliance of the Golden Witch
Chiester 00 is summoned by Kinzo Ushiromiya to lead the six sacrifices for the first twilight.
- Chiester 00 is named after the #00 buckshot shotgun shell.
