Zuikaku is a Japanese aircraft carrier shipgirl in Azur Lane, one of the Crane Sisters alongside her older sister Shokaku. Both sisters are based on cranes, characterized by wing-shaped decorations on their collars. Zuikaku is known for her active and competitive nature, harboring a strong rivalry with Enterprise that stems from repeated defeats. Despite her initial tendency to blame herself for not being strong enough, she learns to rely more on her colleagues for support. She shares a close bond with Shokaku and enjoys the food her sister prepares. Throughout the Azur Lane narrative, Zuikaku participates in major battles, including efforts to stop Kaga and ultimately joining forces with Enterprise to fight against the Siren threat.
