Things take a more serious turn with the arrival of (or Lyril), a mysterious girl from the planet Mechatopia who has been sent to scout Earth for an invasion. She reclaims the robot and reveals that she plans to use the mirror world as a base for the Steel Troops, a massive robot army, to conquer Earth and enslave humanity. What follows is an emotional race against time. The story beautifully subverts tropes when Shizuka nurses the injured Riruru back to health, planting seeds of doubt in Riruru's programmed mind about her mission and the very concept of enslaving other beings. This culminates in a heartbreaking finale where Riruru makes the ultimate sacrifice to alter the timeline, ensuring peace between Earth and Mechatopia.
As the robot army breaches the defenses and all hope seems lost, Riruru and Shizuka travel back in time to change history by altering the programming of the very first robots of Mechatopia. The emotional weight of Riruru and Pippo slowly fading out of existence as they successfully rewrite history is a cinematic masterpiece. The Hindi voice delivery during Riruru’s final goodbye, promising Nobita that she will be reborn as a "winged angel," has left an entire generation of Indian anime fans in tears.
