Isolde

Isolde (イゾルデ) is a character from The King of Fighters series. She is Nameless's first love and continues to watch over him as a spirit. Isolde was a child who was part of the "Anti-K' project" conducted by NESTS and had the power to control ice. However, her abilities were deemed lacking, and she was marked as a defective experiment. She first met Nameless in the infirmary after he had suffered severe injuries in a mock battle to assess combat data. Meeting him significantly improved her impaired capabilities, so she was allowed to see him regularly to nurture her powers. Unfortunately, Isolde tragically died during one of her tests. NESTS, unwilling to waste their progress on her, infused her essence into the special glove Nameless wears to help control his flames. Once Nameless eventually learns this from a fugitive of the syndicate, he decides to continue working for NESTS with the hope of one day restoring her to her original body. It is said that Isolde lives on in Nameless's glove, with frequent apparitions of her whenever he uses his powers.
