Shoukaku is an aircraft carrier from Azur Lane based on the historical Japanese warship of the same name. She is one of the Crane Sisters, alongside her younger sister Zuikaku, with both characters designed around crane symbolism reflected in their names and wing-shaped collar decorations. Known for her gentle demeanor and culinary skills, Shoukaku serves as a stabilizing presence in the game's narrative. She maintains a close bond with Zuikaku and participates in major story events, including battles against the Sirens and conflicts with other factions. Unlike many Japanese ship characters in Azur Lane, neither she nor Zuikaku possess animal ears or horns.
