Subaru:  Even though it had little strength behind it, Subaru wobbled as if he had been thrust away, grabbing hold of the railing to support his body.

Subaru:  —This was Roswaal L. Mathers, the man who lived for a wish that was four hundred years old. He would never seek to inflict undesired suffering upon Subaru and Emilia again. If Subaru wished it, he would no doubt cooperate to work toward Subaru’s objectives, even lending Emilia a hand with his full strength. But if Subaru miscalculated even slightly, Roswaal would flip the table over, rendering everything futile. This was no lie or deception. Roswaal absolutely would do it for the sake of his greatest desire.

Roswaal:  "My, there is no need to be so frightened. So long as you remain true to yourself and continue in your duty, I shall cooperate with you fully—this is simply the new pact between you and I."

Subaru:  “…I’ve learned that for pacts, you have to check not just the fine print but the guy you’re signing it with, too.” Subaru’s sarcasm and anguished sigh made Roswaal widen his eyes.

Roswaal:  "Ah, yes." He says, lifting his face after laughing for a while. "I only just said I would cooperate in full, so there is something of which I must properly inform you."

Roswaal:  “In the royal capital and this time, that makes it twice that I have hired the Bowel Hunter. But the girl in bonds underground…this Beast Master, I had nothing to do with either of her attacks.”

Subaru:  “—Huh?” Subaru, on guard for what more might come, could only drop his mouth wide open. The girl held in bonds underground meant Meili, captured at the mansion and kept prisoner since. At present, the death of her partner in crime, Elsa, had left her too uncooperative to deal with in any other fashion. That had hurt his head enough, but Roswaal’s next words were a thunderclap out of the clear blue sky.

Roswaal:  “This time, my contract only targeted Beatrice. In accordance with the book of knowledge, I was to liberate that girl from her twisted fate… But if I heard correctly, those girls had plans that went beyond my request, did they not?”

Subaru:  “Yeah, Elsa and Meili were part of the same group, I figure, so Meili was helping her out with her contract. Because if that wasn’t the case, who could’ve tipped them off about the mansion’s interior like that…?”

Roswaal:  “—In other words, there was another culprit who planned this attack on the mansion besides meeee.”

Roswaal:  “Your troubles shall continue. Truly, that is where you shine. You really are cut out for struggling, are you not?” Letting those words of sarcasm dangle, Roswaal inverted his now-empty glass over his mouth. A single droplet of alcohol fell and struck his lips.
