Kaito:  And the noise of the walls and ceiling sounded like an orchestra. Kaito, in his black uniform, played the role of the conductor, waving his arm both violently and delicately. The blades were his instrumentalists, and they wove their shearing melody in accordance with his directions. The time it took felt like it lasted an eternity. But every performance must eventually come to an end. Ten or twenty seconds later, Kaito swung his arm wide, then brought it to a sudden stop. All at once, the blade disappeared. Silence descended upon the room. The only sound left was the faint trickling of blood. The nursery-like chamber had been completely ruined. Chunks of flesh and viscera littered the floor, and everything in sight was red. A thick, rusty smell began filling the air. Amid the tragic spectacle, the first demon slumbered gently, as though nothing had changed. Kaito averted his gaze from it, instead looking at the blood gathering at his feet.

Kaito:  “Good night, everyone. Sweet dreams.” As he faced the vast pool of red, he let out a gentle whisper. In a sense, his words were tinged with madness. But they came from the heart. After all, he’d heard a continuous scream from the moment he’d first set foot in the room. It was a striking, sorrowful plea, one that only someone who’d experienced extreme pain could perceive. Please kill us, they’d been saying. Please make it all end. The people being used to pacify Diablo had long since gone mad from the pain. But in spite of that, they’d never stopped their desperate supplication. And now Kaito could hear their pitiful cries no more. He cast his gaze around the room, his expression full of affection and sadness. He looked to make sure they were all dead, that there were no sacrifices left in the room. After determining that to be the case, he let his face turn serious again. Having coldly wiped away his expression, the Kaiser’s contractor turned on his heel. Then, alone, he began walking.
