As Iczer-3's partner, she develops a powerful telepathic bond with the gynoid. Shortly after, she also begins to frequently experience strange dreams. These dreams are in fact a flashback to the "Iczer-1" OVA, revealing that she is the granddaughter of Iczer-1's partner, Nagisa Kanō. Like her grandmother before her, Nagisa's emotional state is the key to powering Iczer Robo in battle, though it is later revealed that is the core power source. She also acts as Iczer-3's guardian while she is on Earth, and when Iczer-1 arrives on Earth, Nagisa seems to immediately recognize her. Likewise, due to her intimate connection with Nagisa's grandmother, Iczer-1 knows Nagisa very well.
