Subaru:  Receiving this, Subaru put more strength into his legs, with which he kicked at the snow—Emilia was ready, but until Subaru’s end was ready—a little more, just a little farther, just a pinch, go, go, go! Without even time to let out his breath, Subaru laid a marker on the snowy plain at his own feet. With this, his do-or-die escape from the Great Rabbit, which was hot on his tail, had finally neared its end. With that purple-arrow marker thrust into the snowy plain, everything had come together—so he shouted: “Now, Emilia! Trace the lines—! !”

Subaru:  Plowing through the snow as he came to a halt, Subaru relied on magic for his last stand, commanding the purple arrow, “Let there be light!” The very next instant, countless purple arrows that had been shot into the clearing began to glow, forming a glittering cage.

Emilia:  A horde of tens of thousands of wriggling white demon beasts had been penned up inside that square cage— “That’s Subaru for you! Really good job!” Praising the splendid outcome, Emilia let up a voice of joy that she’d normally never ever make. Then as her eyes glimmered with equally rare aggression, she trained a graceful finger toward the demon beasts within the cage. —And then she unleashed all the mana she had been forming while Subaru had bought her time. “Cocytus!”

Subaru:  Applying that incantation, unfamiliar to his tongue, Subaru activated the vast amount of surging mana, transmitting power to the purple crystals, which were arrayed in a square around the clearing, one after another.

Action:  The lines connected. With a roar, the ground, the snowy plain itself, floated skyward.

Subaru:  “Amazing…” Seeing this unfold left Subaru dumbstruck. The spectacle was so overwhelming, it left him speechless.

Action:  Emilia carefully supplied magic energy all along the sides of the cage of purple arrows in the clearing, shutting the Great Rabbit inside a snowy cage and lifting them into the sky. Of course, had they been normal demon beasts, they would surely have noticed the abnormality and escaped from the cage—but the Great Rabbit possessed no such decision-making capacity. They were incarnations of hunger, felt inexhaustible urges of Gluttony, and were children gifted with Daphne the Witch’s empty stomach—

Subaru:  “That’s why now you’re all one step from a Giltirau and stuff!”

Subaru:  “—With this, there’s nowhere left for you to run!” As Subaru raised a middle finger and levied his insult, Emilia put on the finishing touches.

Action:  Emilia used magic energy to weave together an icy lid she simultaneously slammed down onto the patch of snowy ground that had floated into the sky, completing the cage and trapping the massive number of demon beasts. Even if the Great Rabbit had a will of its own, there was no escape now that the icy prison was fully formed. From the snow-stripped clearing beneath the prison, he looked around. Stragglers, zero. Wriggling figures, zero.
