Steel Angel Kurumi Encore

Nako Kagura, who is the great-granddaughter of the main character from the previous series, is introduced as a high school student and budding singer who also has the chance to learn about Kurumi and the Steel Angels' existence 75 years later. Unfortunately, Uruka Sumeragi, Nako's affluent childhood friend, becomes upset and angry after Kurumi steals her first kiss. She then does all in her power—including using her father's highly skilled agents and potent mecha-like robots—to overcome Kurumi and regain Nako's affection.
