She was one of a few Japanese ships in-game to be built abroad (besides Kongou). In her case, at New York Shipbuilding Corporation, at the same time as Saratoga, before her conversion (for this reason, she is the key for building Saratoga with LSC). However, she shows very little traces of her birthland and instead acts as the token minority of the fleet. Her design is heavily influenced by the Ainu, featuring distinctive patterning as well as a few clothing items and objects.
She is the only ship in the game to change ship class three times as well as the only ship who irreversibly (but nominally) return to their original ship class. As Kai Bo, she is the only other ship other than Akitsushima to field Flying Boats.
