Subaru:  “—” Having dragged the answer out of the man, Subaru sucked in his breath but once. Then, he said

Otto:  “…Huh?”

Subaru:  "I said, turn back. Rem—we have to save her! Turn back right now!” Subaru leaped into the narrow driver’s seat and grabbed Otto by his collar.

Otto:  Confused and still occupied with controlling the land dragon, Otto was unable to respond to Subaru’s act of violence. His face went pale as his collar was grabbed.

Otto:  “A-are you serious?! Turn back… Turn back and do what?! Did you not see how terrifying that monster is?! It’s suicide!”

Subaru:  “I’m telling you to go back to where we saw the monster so we can save Rem, damn it! !” When Otto refused his command, a vein bulged on Subaru’s forehead as he shouted in anger. The menace of the White Whale had been burned into Subaru’s very eyes. The giant creature swam through the air faster than a land dragon could run; a single, casual slap of its tail could rend a carriage asunder. Even within the blinding mist, it unerringly located its prey; even Rem’s magic hadn’t inflicted any damage. Without doubt, it was the largest and mightiest of all the foes he had seen since arriving in this other world. Compared to the menace it posed, dealing with Elsa, classified as a human being, and the pack of countless Urugarum was far easier to plan for. But he couldn’t even dream of a way to defeat a monster on that scale.

Subaru:  “And Rem couldn’t, either… We can’t just leave her. If we do that…!” Subaru was well aware of how strong Rem was in her Oni state. But his familiarity with her abilities meant he could plainly state that it meant nothing before the might of the White Whale. If he left Rem behind, he would lose her for certain. Then everything would be pointless. Then there would be no meaning in Subaru surviving. Rem was an irreplaceable part of the future Subaru desired. If she wasn’t there, Subaru would lose sight of even his own self. He would have no one to accept him. Subaru needed her to give him affirmation.

Subaru:  “I won’t let her sacrifice herself to buy time! Turn back right now, Otto! If you don’t…”

Otto:  “Have you lost your mind? !” However, Otto’s angry shout interrupted Subaru’s plea. Still grasping Otto’s collar, he felt a squeeze on the back of his wrist; in the next moment, he was slammed against the driver’s seat back first.

Subaru:  “Agah!”

Otto:  “You think you can force a traveling merchant tearing down a highway without a blessing? You underestimate me!” With Subaru facedown, Otto twisted the wrist in his hand, straining Subaru’s shoulder to its limit—still grasping the reins with his other hand all the while.

Otto:  “At any rate, calm down! Look at yourself. What can you do in a state like this? Do you plan to put to waste the feelings that girl left behind?”

Subaru:  “Don’t you talk about Rem!
