She has feelings for Duke Fleed having known him as Daisuke Umon prior to him regaining his memories and wishes to help him in any way she can.

Hikaru is a capable pilot able to control the Marine Spazer with little difficulty on her first try.

Later Daisuke regains his memories as Duke Fleed and pilots the Grendizer to help Koji. At some point Hikaru finds out Daisuke's true identity. For the first part of the series, Hikaru remained on the sidelines watching as Duke fought against the threats from the Vegan Empire. She later shows her piloting skills with the Marine Spazer with more battles and joins Duke in battle. Hikaru starts to worry about Duke when begins to have thoughts of ruling the Earth after a fallout between him and Dr. Umon. As war broke out from all sides, Hikaru joined her comrades in battle. After Raaga activated its programming to stop nuclear war, Hikaru was forced back from Grendizer as it dove to chase after the ancient machine. She and Koji were the only known survivors of the carnage and they leave to find more survivors.
