Bambietta Basterbine

is a Quincy and a member of the Vandenreich's Stern Ritter, with the designation "E".

Appearance
Bambietta is a relatively petite and young girl with long, dark hair. Her attire is a variation upon the Stern Ritter's typical white uniform, consisting of the order's signature hooded-cloak and a thigh-length trench coat, as well as knee-high boots and black stockings. She also wears a heart-shaped belt buckle and a white cap, which features a black peak and the Vandenreich insignia emblazoned on its front.

The Thousand-Year Blood War arc
Upon receiving the orders of the Vandenreich Leader, she and the other Stern Ritter gather at the Gate of the Sun, before traveling to Seireitei in order to participate in the conquest of Soul Society.

Once there, she and the other Stern Ritter create pillars of blue flames prior to engaging the Shinigami in battle. Gleefully massacring a number of Shinigami, Bambietta is stopped by Captain Sajin Komamura, who remarks upon the little girl being in the enemy army. She retorts that since even a dog could become captain, Soul Society must be desperately short of soldiers. With the arrival of Lieutenant Tetsuzaemon Iba, Komamura unleashes his Bankai, Kokujō Tengen Myō'ō, only for it to be stolen by Bambietta's unnamed device.

Equipment
Medallion: Bambietta possesses a round, unnamed device that is roughly the size of a person's palm and has the Vandenreich insignia etched into its surface. When activated, the device is capable of stealing a currently released Bankai in the immediate vicinity, as evidenced when Bambietta used it to take Sajin Komamura's Kokujō Tengen Myō'ō.

Spirit Weapon
Reishi Weapons: Using her abilities as a Quincy, Bambietta is capable of concentrating both spirit energy and particles in order to transform them into weapons. Her favoured weapon allows her to bifurcate multiple Shinigami and their respective Zanpakutō with apparent ease.
