Servants:  “Entertaining a guest?” “Going on a trip?”

Roswaal:  A pained smile came over Roswaal as he pointed at Ram. “Ram is correct… I am heading out. A somewhat troooublesome message has arrived, you see. There is something I must check in the environs of Garfiel, though I do not plan on being very laaate.”

Subaru:  Having never heard that particular word before, Subaru couldn’t be certain whether it was the name of a person or a place. But given that the twins seemed to know what he was talking about, Subaru nodded without objection.

Roswaal:  “For that reaaason, I do not believe I shall be back tonight, so…Ram, Rem, I leave matters in your hands.”

Ram:  “Yes, if you command it.”

Rem:  “Yes, even at the cost of my life.”

Roswaal:  Roswaal acknowledged the pair’s immediate replies with his oddly colored eyes alone before gazing at Subaru with them.

Subaru:  Subaru, feeling backed into a corner by the differently colored glints, squirmed uncomfortably. “Sorry, I’m not loyal enough to swear even at the cost of my life yet.”

Roswaal:  “That is fine and weeell. If you swore that all of a sudden, it would feel raaather disconcerting. But I leave things in yooour hands as well, Subaru.” Roswaal patted Subaru’s shoulder, one eye closed, so that only his yellow iris was visible. “This has a fishy aroma to it. I can cooount on you to take care of Lady Emilia, yes?”

Subaru:  “Yeah, you can seriously count on me for that.” That went without saying. Subaru didn’t know how much of a read Roswaal had on the situation. He didn’t know, but he’d picked up this much… —This had never happened before. Perhaps it truly meant that Subaru’s actions had changed the world around him.

Roswaal:  Nodding, Roswaal gave Subaru a satisfied smile before giving his faithful twin retainers various instructions. “Well, theeen, I shall be off. I pray that nothing shall occuuur.” As he spoke, Roswaal went out the entrance, with the three of them watching him go. But Subaru belatedly realized that there was no coach or carriage to whisk Roswaal away. Surely Roswaal wasn’t going to walk—

Roswaal:  “Well, I leave it in your hands—” When Roswaal spoke, his overcoat flapped as he made a light leap. And then, Subaru saw: Roswaal’s body sailed up into the sky, wind wrapping around it as he soared at high speed.

Subaru:  Subaru’s mouth opened in surprise as Roswaal rose almost as high as the clouds, heading toward the mountains, growing smaller, and finally vanishing from view. “H-he flew… Geez, magic’s amazing stuff.”

Rem:  In contrast, the sisters, clearly accustomed to Roswaal’s flight magic, quickly switched gears. They instantly established the order of affairs in the mansion in the absence of their master. “Even if Master Roswaal is absent, our duties do not change. Indeed, the fact that he is not present means we must be even more diligent.”
