As the Dragon Mecha suffers severe damage and communication cuts out during a fierce battle, its pilot channels all remaining power into the core, risking life support to activate a hidden reserve mode. Meanwhile, a former loyal Federation pilot confronts betrayal from his own squad, determined to keep the powerful Ark Core from falling into enemy hands. News spreads of top pilot Dylan's supposed death at Demon Abyss, but a mysterious rebirth reveals he now inhabits Howard's body, a clan heir tied to the Ark Core. The episode ends with dormant mechas and spiritual energy running low, setting the stage for an uncertain struggle ahead.
Jane, Howard's sister and a mid-level first-tier mecha pilot, wakes from the hospital determined to protect her family’s legacy after their parents died fighting demons. She suspects Howard’s recent drowning is linked to the powerful Spiritual Energy Jade their family possesses, which has caused greed within the Shaw family. Jane plans to use the Jade’s energy to restore her Ark Core and boost her mecha. At the start of the family competition, Jane faces harsh insults from relatives demanding the Jade be handed over, escalating the conflict as she struggles to prove her strength and protect her claim.
The Shaw family faces turmoil after Howard’s reckless behavior sparks accusations of theft from heroes' descendants. Jane Shaw is pressured to redeem the family honor by competing in the clan’s upcoming mecha test, which will decide leadership eligibility. Her uncle warns that failure means returning the Spiritual Energy Jade and possible banishment for both siblings. In a tense challenge, Howard foolishly confronts their uncle despite lacking a bonded mecha, raising the stakes. As the competition begins, Jane steps up to face the first round, the demon test, piloting the Crane Mecha to prove her worth, while the fate of the Shaw family hangs in the balance.
During a high-stakes mecha competition, Sheila Shaw faces a dangerous first-tier demon with her unstable Crane Mecha, which has only reached C-class despite her A-class potential. As her opponent's ape mecha feeds off spiritual energy and goes berserk, Sheila narrowly survives the attack. The Shaw family, critical of Howard and intent on reclaiming the Spiritual Energy Jade, watches closely. Chad Shaw encourages Sheila after she first manifests spiritual energy, signaling her growth as a pilot nearing second-tier status. The episode ends as Chad prepares to enter the competition with his Scorpion Mecha, leaving the outcome uncertain.
At 19, Chad is a highly skilled, second-tier mecha pilot in West City, renowned for piloting the elite Scorpion Mecha with powerful earth-type defense and venom-type offense. As he faces off against brutal beasts, Chad relies on nimble footwork and precise tactical anticipation to outmaneuver his foes. However, another person challenges the value of Chad’s tactics, arguing the demons’ overwhelming force leaves no room for strategy. Despite this, Chad’s venom attack proves far stronger than typical B-class mechas, revealing his true strength exceeds his official ranking, setting up a critical test of his abilities.
Chad amazes onlookers by skillfully enveloping the scorpion tail with spiritual energy, showcasing unparalleled talent that hints at his family's rise. As Chad finishes, he passes the challenge to Jane Shaw, who commands the powerful A-class Phoenix Mecha thanks to a Spiritual Energy Jade left by their father. Despite skepticism that the A-class mecha should belong to Chad, Jane follows Chad's exact strategy, cleverly conserving energy to outlast their brute-force opponent. The episode ends with tension rising as Jane prepares to strike, leaving viewers uncertain if she will secure victory.
During a fierce battle, Jane faces betrayal as her own Scorpion Mecha covertly attacks her, revealing Chad's plan to harm her through deception. The enraged Horned Demon Ape complicates the fight, forcing another pilot to restrain themselves from summoning the powerful Dragon Mecha, which could trigger dangerous resonance with the Ark Core and implicate both Jane and themselves if detected by Loki. With limited spiritual energy, the pilot must rely on a precise move to subdue the ape. The episode ends as the ape's rage suddenly subsides, leaving the outcome uncertain.
Jane returns injured, unable to join the next round, sparking criticism from her rivals who accuse her of being unworthy to hold the Spiritual Energy Jade.

Howard defends her against the insults but is overruled. The conflict escalates until an unexpected challenger steps forward, demanding a duel to claim the Jade, forcing all parties to agree that whoever wins will settle ownership of the Jade once and for all.
Howard, who lacks a bonded mecha, is challenged by Sheila in a high-stakes duel where Howard must fight to protect his family's Spiritual Energy Jade. Against all odds, Howard uses a mass-produced mecha that others mock for its inferior specs. Despite initial setbacks, Howard's mecha unexpectedly manifests full-body spiritual energy, a rare ability beyond even third-tier pilots. This surprising power shifts the fight’s momentum, leaving the outcome uncertain as Howard’s resolve and the mecha’s hidden strength come into sharp focus.
As the Federation's greatest mecha master, Dylan was betrayed by his disciple Loki at the Demon Abyss.

In a world overrun by demons, Howard balances a burning drive for vengeance against the vulnerability of his new life.
