Kai, Nagisa

甲斐渚

A typical high school student who aspires to become a professional wrestler. One day, a robot named Iczel confronts Nagisa and urges her to help save the world from invading aliens. Although she initially refused, Nagisa had no choice but to merge with Iczel to become an Iczelion (Ikuserion). She struggles at first because she does not want to bear the responsibility of being an Iczelion and saving the world, but later realizes that she must protect those she cares about, giving her the strength to become an Iczelion and fight to save the Earth. She can enter Burst Acceleration Mode for a brief period of time.
