Subaru:  Looking farther, he was certain the entirety of the building was already engulfed by flames; the inferno touched not only the main wing, where the fire had started, but also the east and west wings. It was difficult to find a place inside the mansion that was still in its original shape. Even the door of the entrance from which Subaru had just emerged had its lower half enveloped by flames. That Passage had worked at all was itself a miracle. He wouldn’t be able to leap back into the archive of forbidden books from there—No, it was questionable whether there was a single door leading to the archive remaining in the mansion. He wasn’t inside the burning mansion; he’d been thrown outside. Beatrice had probably intended this to be her reply.

Subaru:  “Good-bye, my ass—How are you gonna act tough, then show me a face like that at the end? !” Brushing those rising doubts aside, Subaru kicked the burning door in all his fury, rushing into the entryway. He was immediately greeted by a wave of heat incomparable to anything he felt outside, and the agony of his singed windpipe brought tears to his eyes. Charging into a burning building like someone who didn’t know better, trying to save lives and be a hero—that was the kind of dumb stunt that got people killed. But Subaru had no intention of dying.

Subaru:  “And I’m not letting her die, either!” Subaru raced across the flaming Roswaal Manor in search of anything that might be connected to the archive. His face, his neck, and his limbs were roasting, and his skin felt pain as if it was being scorched. It hurt to breathe, but not so much that he couldn’t run. Subaru shoved everything else out of his mind. If Subaru had been capable of seeing things more clearly at the time, the sheer horror of the sight might have caused his body to quiver uncontrollably. For as Subaru ran through the inferno, swearing he would bring the girl with him, he was enveloped by an incredibly dense black miasma, almost like a cloak of shadow that shielded him. Unaware of this, Subaru broke through a particularly large wall of flame and found the stairs. The first-floor dining room was where the fire had begun. Entryway included, it was highly probable that every door there had burned up. If there was a door still intact, it would be on a higher floor—probably at the very top. In such a conflagration, it was naturally unlikely that he could get back up there from the first floor. Even so, without any hesitation, Subaru started climbing the stairs, racing toward the topmost floor.
