Helena is a Light Cruiser from the Eagle Union in Azur Lane, modeled after the historical USS Helena. She is depicted as a cute, bespectacled girl with a timid and shy personality, often crying and seeking the Commander's protection. Despite her frailty, she is the developer of the CX radar system, making her an invaluable radar expert and support ship in battles. Her lines reflect her dependence on the Commander, calling them her 'hero' and expressing fear of sorties without them. Helena has multiple skins, including META and wedding versions, and is known for her META storyline involving ascension and protecting experimental fields.
