I raise my hands in defeat! I mean my hands are probably rising up right now out of the sea in defeat.
Antarcticite isn’t willing to immediately accept that Phos’ arms are lost, but instead braves the frozen depths (and the colliding ice boulders therein) in search of them, to no avail. Upon reporting to Kongou, Antarcticite takes full responsibility, citing inexperience in working in a pair, but Kongou blames his own lack of caution.
He has Antarc and Phos travel to the Chord Shore, where all Gems are “born”, to find material for new arms. There, they witness something akin to such a birth, albeit far less advanced and complete. The reddish crystals simply fall into the snow, lifeless and inert.
The beach is littered with gold and platinum deposits—deemed worthless by Antarc for their high weight and malleability. Still, there’s nothing else around, so Phos is fitted with temporary gold arms in the absence of more suitable material. The results are initially…not promising:
Um… I’m kind of getting engulfed. Wouldn’t you say I’m being engulfed?
Worse still, the clouds part and Lunarians appear both over the Chord Shore and surround headquarters, keeping Kongou from racing to the Gems’ aid.
In an all-but-no-win scenario, Antarcticite shows true grit and valor, using the saw as a snowboard and taking out as many Lunarians as possible before they unveil yet another new tactic: fishing tackle and hooks that entangle Antarc. Only a burst of nearly self-shattering strength severs the connection, but the Lunarians still don’t disperse.
Antarc manages to yank their stolen hand free and cause the Lunarians to disperse, but not without nearly shattering as well. Though extremely fragile, Antarc attempts to break Phos out of the gold prison, but another Lunarian arrow reduces Antarc to a cloud of crystal shards. Before being carried off, Antarc orders Phos to remain silent, buying Phos time.
Phos…doesn’t remain silent, instead managing to find a way to control the new gold “arms”—a term that doesn’t really do the new shapeshifting appendage(s) justice—and attempt a desperate counterattack to retrieve Antarc’s fragments.
Phos pushes the absolute limit the gold’s ability, acting both as a means of propelling their body into the sky, absorbing or blocking projectiles, and grabbing and throwing Antarc’s sword. Also pushed to new dizzying highs – the increasingly intricate CGI, put to good use. The shimmering, “gooey” liquid gold presents a stunning contrast to the brittle frozen backdrop.
It’s a valiant effort, but ultimately futile, as the Lunarians retreat too quickly for Phos’ attacks to reach them. Phos ends up badly cracked and plummeting to the ground, but is caught by Kongou, who arrived too late to save Antarc. Still, were it not for Antarc, Phos would be gone too.
Phos acknowledges that sacrifice while lamenting Antarc’s loss, and is likely now possessed of a new iron determination to master their new golden “inclusions”, to prevent (or at least make it more difficult) for the Lunarians to capture another beloved comrade and friend.
As the end credits roll over a somber view of Antarcticite’s now-abandoned quarters (with a lovely new song sung by Phos’ seiyu), I’m devastated by Antarc’s sudden loss, despite not knowing they existed just two episodes ago. Antarc made a huge impact on the world of Houseki no Kuni, performed momentous deeds and fought for Phos till the bitter end, and in this writer’s opinion, left us far too soon.
