Jingbai is a character who appears in the fifth season of the animated series The Daily Life of the Immortal King. This entity is not a separate individual but rather the result of a fusion between two related characters, Jingke and his sister. The sister, who serves as a scabbard, confronts Jingke, accusing him of having abandoned her. During the ensuing conflict, the Rat Squad, a group of antagonists, launches an attack. In response to the threat, Jingke protects his sister by merging with her, and their combined form is called Jingbai.

The primary motivation for the creation of Jingbai is protection and unity in the face of a common enemy. By merging, the two resolve their personal conflict and combine their strengths to become a powerful warrior capable of defending themselves and others. In the episode where this fusion occurs, Jingbai quickly and efficiently defeats the attacking elite force of the Rat Squad. The character serves as a demonstration of how siblings can achieve great things when they support each other, as remarked upon by another character present for the event.

Jingbai's role in the story is that of a temporary, combined fighter who appears to resolve a specific confrontation. The character does not have an independent personality or a long-term developmental arc, as the fusion is an event-driven transformation. The key relationship defining Jingbai is the bond between the two siblings, Jingke and his sister, whose reunion and cooperation are physically manifested in this merged being.

Notable abilities include the combined combat prowess of the two individuals. As a fused entity, Jingbai possesses the strength and skills necessary to overwhelm the Rat Squad's elite forces with ease, showcasing a significant power level that surpasses either sibling on their own. The character has an English voice actor listed for the role.
