Bambietta Basterbine

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

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

Personality
Bambietta is a particularly sadistic individual, evident in how she screams in joy as she slaughters her enemies. She is not above attacking her male subordinates to vent her frustration, sometimes bringing them into her room under false pretenses before killing them without remorse.

The Thousand-Year Blood War arc
Upon receiving the orders of Yhwach, she and the other Stern Ritter gather at the Gate of the Sun before travelling to the 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 7th Division Captain Sajin Komamura, who expresses disbelief at a little girl being in the enemy army, prompting her to state if even a dog can become captain, Soul Society must be desperately short of soldiers. With the arrival of 7th Division Lieutenant Tetsuzaemon Iba, Komamura unleashes his Bankai, Kokujō Tengen Myō'ō, prompting Bambietta to steal it with her medallion.

When Komamura rallies a number of Shinigami with a rousing speech citing Captain-Commander Genryūsai Shigekuni Yamamoto's recent actions, Bambietta questions how this is possible, for they were on the verge of death just moments before. She is later confused when Ichigo Kurosaki's Reiatsu abruptly vanishes after his arrival in Soul Society.

Following the Wandenreich's retreat from Soul Society, Bambietta is present when Yhwach appoints Uryū Ishida his successor, an announcement that shocks her. Soon after, she orders a male subordinate to accompany her to her room, under the pretense of "doing it". However, in her room she vertically bisects the man, killing him. Four of her fellow female Stern Ritter enter the room, chastising her for her habit of killing attractive men when she is annoyed. When they start to bicker among themselves, Bambietta tells them to shut up, as she is worried about the future of Wandenreich.

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

Powers & Abilities
Great Spiritual Power: Bambietta's spiritual power is on a level comparable to or greater than that of a captain-level Shinigami. She is powerful enough to fight several Shinigami simultaneously, including Sajin Komamura and his lieutenant, and push them to the brink of death.

Reishi Absorption: As a Quincy, Bambietta can absorb Reishi from the atmosphere and combine it with her own Reiryoku to form weapons and use different techniques.

Spirit Weapon
Reishi Sword: Using her abilities as a Quincy, Bambietta can concentrate both spirit energy and particles in order to transform them into weapons. Her favored weapon manifests in the form of an ornate and short broadsword, somewhat reminiscent of a Chinese dao, with a forked blade in the style of Zulfiqar. Using this sword, she can bifurcate multiple Shinigami and their respective Zanpakutō with ease.
