Aika Sumeragi  

, 皇藍華

Aika is widely regarded as one of the top performers in her field. Her parents, both scientists, raised her as an experiment and tragically passed away during a devastating earthquake. Despite this, she was protected by a special suit designed by her parents, which allowed her to survive. She was later taken in by Aida Gozo, who raised her and eventually employed her as a salvager. Aika's battle suit is made of an alternate metal known as ultranate, shaped into a golden bustier that transforms her into a dark-skinned and blue-haired woman with incredible strength and resilience. However, she dislikes the perfection attained by this transformation and tries to avoid relying on it. Although not featured in the anime, Aika is referred to as Shivie Aika in this form. Aika frequently clashes with Gust, who either attempts to steal her bounty or flirts with her. She will stop at nothing to complete her tasks, even if it means compromising her moral values.
