Sheeta, Pazu, and Mu En found Laputa’s grave-keeping robot and learned its comforting gestures were programmed routines, before violent tremors revealed that the city’s protective field was rapidly failing. As the group and Dola’s soldiers fled toward safer ground, Dola spotted something beneath Laputa that appeared to be causing the quake.

• The robot offered Sheeta its last white flower, then ignored her questions and walked into the forest.
• Mu En explained that the robot followed programmed commands, while Pazu vowed to punish whoever had destroyed the other robots.
• Laputa shook violently, and Mu En sensed its protective field weakening as cold air leaked in from above.
• Mu En carried Pazu and Sheeta after the robot as it raced out of the palace, suspecting the mastermind was about to appear.
• Dola ordered the soldiers to evacuate to the upper garden and signaled the Goliath to move away from Laputa.
• Dola saw the Fallingstar Beast trembling at the ruins and followed its gaze to the city’s core, where she spotted the apparent cause of the earthquake.

A mature star-spawn emerged from Laputa and attacked the Fallingstar Beast, overwhelming it with a concentrated gravitational beam. Mu En arrived in time to save Niuniu, then recognized the monster as Astel, Naturalborn of the Void.

• A huge star-like insect creature emerged from Laputa and locked eyes with the Fallingstar Beast.
• Dola warned everyone to flee as the two monsters fought, and the adult's beam pierced the Fallingstar Beast's Gravity Ray, devastating the ruins.
• The adult prepared a second attack while the weakened Fallingstar Beast tried to escape.
• Mu En crashed onto the adult's head with a Golden Power Hammer, interrupting its attack and knocking it toward the sea of clouds.
• The adult recovered from Mu En's blow, and he identified it as Astel, Naturalborn of the Void.

Mu En discovered that an enormous Astel had been feeding on Volucite energy inside Laputa and fought to protect the gardener robot and the children. After Astel overwhelmed his gravity powers, Mu En armed himself and challenged it to battle.

• Mu En identified the giant creature as an Astel that had likely caused Laputa's tremors and the loss of Volucite energy.
• The gardener robot attacked Astel with its proton beam, but Astel teleported away and trapped the robot in a gravity barrier.
• Mu En freed the robot and sent it to regroup with Dola and take control of Laputa while ordering it to protect Pazu and Sheeta.
• Astel struck Mu En with its tail and nullified his gravity manipulation, forcing him down onto the garden lawn.
• Mu En prepared his Crucible wings and a spear of light, then challenged Astel to fight.
