Story

The Ptolemaic Golden Rebel Gigant is deployed, and it leaves nothing in its wake as it heads towards a Rebel Army base.

At the base, several soldiers panic and contemplate retreating. Their transmitter turns into ice and the soldiers try to flee, but their legs have also become enveloped in ice. Beatriz smashes their transmitter and is annoyed by the soldiers' cowardice and simply freezes them completely on the spot. Her bodyguard informs her the Gigant is coming soon, and that reinforcements are on their way, unsure if they'll arrive on time. She tells him that it is completely unnecessary for the reinforcements and orders him to hand her a microphone.

As the Ptolemaics charge towards the base, Damian notices that soldiers of various affiliations are flocking towards their position. The master believer tells him that Beatriz has called them, and despite their affiliations, their morale is quite high. This prompts Damian to assist in the battle.

With the soldiers converged at the base, Beatriz addresses them, though she becomes rather annoyed at their persistence and even threatens to freeze them into ice sculptures, which they also disregard. She orders her amassed force to strike the Ptolemaic gigant and show them the strength of the Subjugation Tactics.

Damian encounters Beatriz and battles her; the two are the only remaining combatants as Beatriz's bodyguards have died protecting her. Damian asks her to surrender, but she refuses and calls him a narcissist. She is unwilling to give up for her sister and fires a stronger laser, noticing Damian's surprised face as she does so.

Mira is later seen talking with Damian, who apologizes for his defeat. Mira excuses him, as it is just one of many small battles and thus insignificant. She then assigns him his next task.
