Makoto leads a double life as a lovestruck girl and the justice-fighting superhero Kogerion, but her journey takes a drastic turn when she is killed by the evil organization Nu~gu. Resurrected by her father in the body of a small child, Makoto reunites with her lover Takeru and discovers that her powers have returned—and perhaps even strengthened—through the power of love, allowing her to take revenge on those who destroyed her.
Makoto's peaceful life is disrupted when Sasurina's minions attempt an ambush on a crowded train. While she finds a new friend in Kozue, the girl is revealed to be a Shogonoid android designed to destroy her. After Kozue takes Takeru hostage and brutally defeats Makoto, Professor Daiginjou restores her to her original form, setting the stage for a renewed conflict with Sasurina.
