Zabimaru (蛇尾丸) is the manifested spirit of Renji Abarai's Zanpakutō. During the Zanpakutō Rebellion initiated by Muramasa, Zabimaru takes on a new manifestation of two separate, humanoid beings; an adult woman and a small boy with a long tail. The boy is attached to the woman by a chain encircling his neck which can be removed at will. The woman, Saru (猿, Monkey), is a tall, curvaceous woman with green fur covering most of her body, with the exception of her chest and abdomen. She has ankle-length, light mallow hair with black markings on her bangs. Her eyes are light green, and she has a beauty mark on the left side of her chest. The chain is wrapped around her waist. The boy, Hebi (蛇, Snake), wears a white and yellow robe which reveals his abdomen. He has blue eyes, short red hair, and triangular white ears. He uses his long tail to balance in the air. Both Saru and Hebi have fangs.

Bleach
Ichigo Kurosaki is an ordinary high schooler—until his family is attacked by a Hollow, a corrupt spirit that seeks to devour human souls. It is then that he meets a Soul Reaper named Rukia Kuchiki, who gets injured while protecting Ichigo's family from the assailant. To save his family, Ichigo accepts Rukia's offer of taking her powers and becomes a Soul Reaper as a result. However, as Rukia is unable to regain her powers, Ichigo is given the daunting task of hunting down the Hollows that plague their town. However, he is not alone in his fight, as he is later joined by his friends—classmates Orihime Inoue, Yasutora Sado, and Uryuu Ishida—who each have their own unique abilities. As Ichigo and his comrades get used to their new duties and support each other on and off the battlefield, the young Soul Reaper soon learns that the Hollows are not the only real threat to the human world.
