Otto:  “The short version, please.”

Otto:  “This is the work of the Beast Master you spoke of, I presume. The interior of the mansion is already filled with demon beasts.”

Subaru:  “That must mean Meili’s here, huh…but she already should’ve been accounted for." Otto’s hushed report left deep creases in Subaru’s brow. The two assailants—Elsa the Bowel Hunter and Meili the Beast Master—were basically sisters of slaughter. The danger Elsa posed was painfully obvious, but Meili’s command over demon beasts was something that could not be taken lightly if they wanted to make it out of this encounter in one piece. So of course, he’d readied a countermeasure—

Petra:  “—But there are demon beasts the repel stones don’t work on at all! !” Even in the darkness, he could tell Petra’s face was red as she shouted and beat Subaru’s question to the punch. The girl was gripping a glowing blue crystal—a phosphorescent stone for warding off demon beasts. This was what Subaru and the others had prepared to neutralize the Beast Master.

Subaru:  “Wait, seriously?! I was sure that if we had these demon-beast repel stones, they’d keep them away like during the Urugarum incident… Why isn’t it working? !”

Petra:  “I don’t know! Perhaps the ones that appeared here are exceptions, but at any rate, assuming these demon beasts have appeared throughout the entire manor, even reaching the marquis’s room will be…”

Otto:  Extremely difficult. Otto left this part unspoken as he finished explaining how the odds had abruptly turned against them.

Subaru:  “—?! ?” Subaru felt an impact come from below his soles, instantly drawing his attention. He quickly noticed there was an odd warping underneath the red carpet covering the corridor floor. It bulged further, and then—it burst. The tremors and deformation of the corridor had merely been a harbinger. The real show of destruction was occurring on the floor below, causing the entire west wing of the mansion to collapse, taking the corridor they were in along with it. The windows cracked, the wooden beams flew apart, and the whole mansion seemed to groan under the strain. As he lost his footing, Subaru found his body suddenly floating in midair. Reflexively, he reached out and yanked a tiny body toward him. As he fell toward the center of the hole, he tried to at least shield the small child pressed against his chest before they hit the ground.

Frederica:  “—Make sure you don’t let go! !” When that thunderous voice rang in his eardrums amid all the destruction, Subaru did everything he could to obey. A moment later, he felt his body being pulled by the scruff of his neck. Then he was unceremoniously tossed to the ground, which made for an admittedly much softer landing. He felt his cheek brushing up against grass. When Subaru looked around, he saw he had rolled onto the green, open yard outside the mansion.

Subaru:  “J-just now, that was…”

Petra:  “Miss Frederica!” When Subaru shook his head and looked up, Petra leaped out of his arms.
