Subaru:  Though he had witnessed the death of his hated foe, Subaru had only hollow emptiness inside him. The defeat of Petelgeuse meant clearing away the threat posed by the Witch Cult. But Rem, who ought to have been there sharing his joy, had been erased from the world; Emilia, who should have been quietly waiting for him to bring good news upon his return, had died at Subaru’s own hands. The accumulated weight of both their deaths had made Subaru desire his own demise, but in the end, he could not even manage that, and a different avenger had claimed retribution— Subaru had nothing left. He’d done everything over and, as a result, achieved nothing.

Subaru:  “—Now, then.” Subaru felt his own powerlessness beaten into him as the beast quietly looked down upon him. He was reminded anew that the giant beast was Puck; the enormity of that truth made his body quake. He was reminded of how, previously, he’d watched with detached bemusement when the Knights and the Council of Elders at the royal palace had acted so terrified of fighting Puck when they heard his alias.

Puck:  “Let’s talk, shall we?”

Subaru:  —Now, he was painfully aware of just what they had felt back then. The cold was making it hard to think. Already, the pain tearing across his whole body had vanished. Subaru heard the gentle footsteps of his own death drawing near. And just as his body slackened from the sweet premonition that the end was nigh—

Puck:  “Oh, this won’t do. You’re bleeding out too much—I’ll put a stop to that.”

Subaru:  “—Dwah! !” He felt like he was being roasted alive, waking up his fading senses. With merciless pain blocking his throat, Subaru saw that each wound on his body was audibly freezing over. White steam rose as sharp ice connected, stitched, and tethered his wounds, even the ones inside his body. Through this act of treatment, abandoning all consideration for the human body, Subaru’s flesh was violently healed. Blood vessels exploded within his eyes, dyeing his vision scarlet. It was more than an ow, ow, ow. The hell that had erupted within his body transcended even pain.

Puck:  “Subaru, you have committed three sins.”

Subaru:  Subaru reeled, howling with a voiceless scream.

Puck:  The giant beast continued to speak as if nothing had happened. Though he had become enormous in size, his mouth lined with endless sharp fangs, and the tone of his voice had changed, the cadence was as gentle as always. That terrified him all the more. "First, you broke your promise with Lia. It seems you do not truly understand just how weighty a promise formed between two people is to a spirit mage. I suppose you truly do not know how much your rashly breaking that promise hurt Lia.” His mind rejected an understanding of what Puck was saying. No—his mind was dominated by pain. His internal organs were frozen, and his broken bones were connected to one another by ice gouging obstructed flesh.
