Doraemon: Nobita and the New Steel Troops: Winged Angels

Nobita throws a temper tantrum over wanting a large RC robot to upstage Suneo. Doraemon flees the summer heat using the Anywhere Door and goes to the North Pole. Nobita follows and stumbles upon a blinking orb that hints at unknown robot power.

The blinking orb summons a giant robot foot that Nobita uses to sled down. He crashes back into his room through the Anywhere Door, and the orb follows, bringing another robot piece into the backyard. The strange device hints that bigger things are coming.

Doraemon admits he has nothing to do with the parts. Using the Opposite World Entrance Oil and the Roll-Up Fishing Hole, they slip into the World Inside the Mirror. There they construct a robot Nobita dubs Zanda Claus and learn to control it with a brain-wave device while inviting Shizuka to join.

Shizuka accidentally presses a panel that unleashes a colossal laser beam, destroying a skyscraper in the mirror world. The group quickly realizes how dangerous Zanda Claus can be. They decide to pull back and confront the threat.

Realizing the threat, they decide to return to the real world and forget about the robot. Nobita, however, has already forgotten the orb’s telepathic messages to Riruru. Riruru begins sensing Nobita and prepares to investigate the strange signals.

Riruru tracks Nobita to retrieve the orb and the Roll-Up Fishing Hole. She takes the fishing hole from Doraemon’s spare pocket and drags Nobita back to the Mirror World to reclaim Zanda Claus. They set a plan to pursue their next move.

Nobita borrows the Fishing Hole again and is drawn to a forested area near Mt. Ura by two shooting stars. He and Riruru prepare for a bigger confrontation as their journey continues. The moment marks a turning point toward Megatopian revelations.

Nobita and Doraemon follow into the Mirror World and uncover Riruru assembling a massive robot army, a human-hating machine threatening both worlds. They stumble upon a sprawling base where the robots push for faster production. The threat becomes personal for the group.

The trio is captured by the robot army, but Pippo and Nobita manage to escape. They regroup and plan a rescue operation to save their friends from the base. The adventure escalates toward a dramatic confrontation.

They witness Zanda Claus being disposed of after its role is revealed, while Pippo enters Zanda Claus to create a distraction. Nobita frees his friends, and Shizuka tends to an injured girl, deepening bonds within the group. Pippo earns Nobita’s trust through his sacrifice.

During a tense moment, Riruru fires a laser at Nobita, but Pippo sacrifices himself to shield him and is badly wounded. This spurs Riruru to reconsider her stance and begin aiding the humans, though she won’t reveal her reasons. The robot commander locks her up, but Nobita and friends mount a rescue.

Back in the real world, Riruru is imprisoned with the Small Light, and the army suspects the fake world. The group goes to the lake to intercept the army, while Shizuka enlarges Riruru and guides her through a Walk-In Mirror to Megatopia, 30,000 years in the past, to consult the professor. The encounter sets the stage for a radical rewrite of the robots’ core.

The professor’s aim is to remove the robots’ competition instinct and replace it with humanity and love. He collapses before finishing, leaving Riruru to carry on with Pippo’s guidance. The stage is set for a radical rewrite of the robots’ core.

Riruru and Pippo near erasure as the reprogramming nears completion, but the professor dies, enabling the final adjustment: Nobita and his friends’ love injects the emotional influence. The reprogramming succeeds, erasing the robot army and causing Riruru and Pippo to disappear from the world. The victory is bittersweet.

Shizuka returns to Earth to reunite with her friends. The next day, Nobita questions whether Riruru and Pippo might be resurrected. Then Riruru reappears with wings like Pippo’s phoenix form, visits Nobita and his friends briefly before vanishing, leaving him hopeful for their return.
