Azur Lane's personification of the US Navy heavy cruiser USS Bremerton (CA-130).
Character design by Katsudansou.
She quickly gained popularity due to her overall design, most notably her very large breasts and navel piercing.
Despite her popularity in the Azur Lane fanbase, Bremerton's real life counterpart had a rather quiet and unremarkable career. She did not enter any combat in World War II (having only been commissioned in late April 1945) and only deployed for minor bombardment roles in the Korean War. She was mainly used as a training ship afterwards, before being scrapped in 1973.
In contrast with her gyaru-ish apperance, Bremerton is actually a friendly and open-hearted individual and, despite a lot of art devoted to her, she is not an "easy" girl, reacting with anger to any undue special touches. As a nod to her historical counterpart's career as a training ship, she usually acts as a mentor and consultant and who is willing to listen to her commander's problems and encourage them.
