Akagi personifies the Imperial Japanese Navy aircraft carrier of the same name. She possesses long brown hair, typically worn straight, and carries traditional archery equipment: a bow and arrows. She wears a muneate (chest protector) over a white and red outfit reflecting her naval origins.
Her personality blends gentleness and loyalty with overconfidence in her combat prowess, referencing her historical role as flagship of the 1st Air Fleet (Kido Butai) in engagements like Pearl Harbor and Midway. She exhibits excessive consumption of resources, especially bauxite and food, earning the nickname "Queen of Bauxite." This gluttony often appears during non-combat situations, such as eating rice or raw ingredients while preparing meals.
Akagi's character arc is rooted in her history. Laid down as an Amagi-class battlecruiser, she was converted into an aircraft carrier under the Washington Naval Treaty. After a major reconstruction from 1935 to 1938, she became Japan's first fleet carrier and a cornerstone of naval aviation strategy. Her operational history includes the Second Sino-Japanese War, Indian Ocean raids, and the invasion of Rabaul before her sinking at Midway in June 1942 after severe damage from dive bombers.
In narrative adaptations, Akagi acts as a senior figure and mentor, notably to the destroyer Fubuki, emphasizing perseverance with the phrase "Hast thou expended all possible efforts?" During the defense of Midway operation in the anime, she confronts the psychological trauma of her historical sinking when encountering an Abyssal Fleet entity resembling the fallen destroyer Kisaragi. This culminates in a near-sacrificial stand requiring rescue by allies. Her combat role is pivotal, often leading carrier divisions and deploying extensive air wings, though extensive damage leads to prolonged repair times reflecting historical constraints.
Gameplay defines her as a "Standard Aircraft Carrier" ("Fleet Carrier" at Kai Ni remodel), featuring high aircraft capacity across multiple slots and stats emphasizing air power and reconnaissance. Achieving Kai Ni (level 90) or Kai Ni E (level 92) remodels significantly enhances her capabilities. Kai Ni E transforms her into a "Night Operations Aircraft Carrier," enabling night air attacks without specialized equipment, grants medium-range engagement, and provides five equipment slots.
Akagi gains stat bonuses when equipped with specific historically associated aircraft like the "Type 97 Torpedo Bomber (Murata Squadron)" or "Ryuusei Kai (CarDiv 1/Skilled)," improving firepower, torpedo accuracy, and anti-aircraft effectiveness. Her relationship with fleet carrier Kaga combines operational partnership and subtle rivalry, evident in joint sorties and competitive scenarios.
In the animated film, Akagi participates in large-scale fleet engagements, demonstrating strategic command alongside battleship Yamato. Her resource-intensive nature persists as a plot point, limiting her deployment to critical missions.
