Subaru:  To Subaru, even though the horn was the very symbol of Rem’s malevolent demon state, it was the only thing that seemed out of place in contrast to the rest. But the circumstances did not permit Subaru such leisurely thoughts. When he looked, he saw scattered demon beasts waiting behind the shadows of boulders and among the trees of the forest. No doubt the beasts were watching their every move. He’d be lunch the instant he showed them the slightest opening. Rem standing before him, the demon beasts standing behind—his life was truly dangling by a thread. Subaru couldn’t move. The demon beasts couldn’t move. The entire situation would hinge on Rem’s next action. He took a deep breath, closed his eyes, and looked straight back at Rem once more. He didn’t know if he could make Rem’s eyes waver, but he had to give it everything he had and leave no stone unturned.

Rem:  "Sister…" Her voice was tired and faint. However, the sound and its meaning thrummed in Subaru’s ears. Her lips quivered, and she seemed out of sorts as her eyes fixated on the side of Ram’s face. Even amid a frenzy sufficient to make her lose her sanity, Rem still recognized the sight of her other half, the sister she loved above all.

Subaru:  Subaru sighed in astonishment. "If I didn’t know better, I’d say you had a sister complex. If that brought you back to sanity, I’m all for—"

Rem:  "—Let her go." She interrupted his words as she flung the iron ball at him with the force of a typhoon. It was close to a miracle that he’d managed to bend his body to the left in time. It was perhaps fortunate that Subaru’s knees were a little wobbly, having not yet recovered from the earlier hard landing. The spikes of the iron ball grazed his right shoulder as it passed. The anguish clawing out his flesh sent his brain into hysteria.

Subaru:  Biting down to hold back a pain-filled shout, Subaru advanced at an angle. "That hurt, damn it!" Subaru turned his gouged shoulder before sidestepping the chain as it lashed downward. A moment later, the chain violently slammed into the spot where Subaru had just been, leaving a snakelike trail on the ground. If Subaru had been any slower in dodging, his back would have borne an identical mark. He shuddered, imagining his flesh rending as he looked at Rem. But Rem looked no different from before. Her eyes were steeped in enmity without having regained their sanity. "Horned form isn’t the problem; it’s whether or not you can control it…" That was Subaru’s guess based on Rem’s current demeanor. If that was the case, the issue was how to restore her sanity. She’d been in a frenzied state the night before, too, but her mind had been more Rem than mad demon in the moments before he’d blacked out.
