Subaru:  Subaru found it surreal to watch the familiar sights and spaces catch on fire as the other two grabbed him by his sleeves and dragged him off. Pulled by the pair, Subaru readjusted Rem on his back as they ran from the burning dining hall.

Otto and Petra:  Otto and Petra used repel stones to drive away any demon beasts that appeared along the way. There were also signs that demon beasts were fleeing the building, instinctively fearful of black smoke and fire.

Subaru:  "But what if Garfiel burns to death from this? !"
gpt
Otto:  "Without the Giltirau prowling around, Garfiel can escape, too! Besides, surely he can send demon beasts packing and leap out of the building all by himself, even without using the escape route!” Subaru was trembling from unwittingly wrecking the entire battlefield, but even in that situation, Otto remained as clever as ever. Thanks to that, they arrived at the upper floor in good order.

Otto and Subaru:  Fortunately, no other demon beasts immune to the effects of the repel stone appeared.

Otto, Subaru, and Petra:  Subaru and company fled into the study, and Petra operated the mechanism on the bookshelf on the wall—slowly, making a sound, the bookshelf moved, and the hidden passage heading underground, linked to the outside, revealed itself.

Petra:  “We did it! Subaru! It’s the hidden passage… With this, we can get out of here! !"
gpt
Subaru:  “Yeah, I suppose so… If you head down to the bottom of these stairs and follow the passage, you can escape outside. The exit will be well outside the perimeter. That just leaves…here, Otto, take Rem.”
human
Otto:  “Yes, I understand. I will take very good care of her.”
gpt
Subaru:  Nodding to Petra, who was overjoyed they had made it, Subaru turned his back to Otto next. Then he slowly, gently passed Rem from his back onto Otto’s. His movements were careful, so as not to let her fall.

Subaru:  "Do not drop her. Do not let her get hurt. And do not touch her in strange ways.”
gpt
Otto:  “Setting your concerns aside, your possessiveness comes across as quite bothersome!”
human
Petra:  “H-hey, you two… Why are you…talking like that?” With Otto now carrying Rem on his back, Subaru flippantly warned to be careful. Hearing this exchange, Petra raised a question with a worried face.
gpt
Petra:  "From the way you’re talking right now…it sounds like Subaru isn’t coming with us…”
human
Subaru:  “—Mm, that’s just how it is. Sorry, but I can’t run with you. From this point on, I gotta go it alone.”
gpt
Petra:  “Why? !” When Subaru confirmed her suspicions, Petra’s face paled as she clung to him.
human
Petra:  “Let’s run already! The mansion’s on fire, and it’ll just make more trouble for Miss Frederica! There’s still a lot of demon beasts, and it’s not like you can beat them if you fight them, Subaru! So let’s run!”
gpt
Subaru:  “Er, well, that’s all totally true, but I can’t run from this. I can’t run… Not yet.” Even though he was happy seeing Petra try to stop him, Subaru gently took her fingers off him one by one.
