Rem:  The destructive weapon, which ought to have been slow and unwieldy, turned with incredible force, following the arc of the swing of her arm to utterly pulverize everything in its path. Its might mowed down branches and snapped tree trunks before slamming straight into the demon beast’s body. The weapon connected with such power it split the torso in two, turning it into fertilizer for the forest.

Rem:  The other soared to angrily sink its fangs into Rem’s left flank—but just before it reached her, Rem smashed her left fist into its snout from above, pummeling it out of the sky. The might of her fist caved the beast’s skull in, slaying it instantly with a blow powerful enough to bury its head into the soil.

Subaru:  “That’s the only thing a weakling like me can say! You’re really out there!” Ecstatic that Rem proved far more reliable than he’d imagined, Subaru leaped as if to embrace her. He then skirted around right behind Rem as the remainder of the pack spread out and surrounded them. Having lost two more of their number, the pack moved sluggishly. The beasts crouched, awaiting their—well, Rem’s—next move; Subaru could tell that there was bitter enmity in their eyes.

Subaru:  “There!” Subaru yelled in concert with Rem’s attack. The iron ball ripped through the air, with the howl heralding the slaughter. A moment before reaching the cluster of demon beasts, the iron ball smashed into the ground, kicking up a huge cloud of dirt. Subaru sensed that the cascade of soil had thrown the beasts off.

Rem:  “Now—!” Rem was the next to yell.

Subaru:  Subaru ran like his body had been shot out of a cannon. The blow from a moment before had opened a hole in the barricade, a narrow area that he could break through. As Subaru flew through the gap, the demon beasts howled at how they had left open a path. But when they rushed in pursuit, they became easy prey to the iron snake lashing behind them.

Subaru:  “Whoa, traumatic sound alert—!” As he sprinted full force, Subaru recalled the sound of the dancing chain sending his left arm flying off. Behind him, the iron ball swung ferociously, making numerous bloody flowers bloom fresh in the dark forest.
