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. She wears the typical white uniform of the Stern Ritter, including the order's signature hooded cloak, along with a heart-shaped belt buckle. She also wears 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 Sun Gate, 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.

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.
