Chapter 5
No one's POV
The assassin struck without warning. Koenma was blown one way, Elsa another, by the force of the explosion triggered by the attack. Before either had time to recover, let alone react, the demon was in Koenma's face again, it's claws moving faster than human eyes could see. Koenma staggered backward, three deep, bloody gashes running across his chest. "Koenma-sama!" Elsa cried, dashing over to his side, catching the Reikai prince as he fell. His face was even paler than it had been in the ice tunnel, and color was rapidly draining. "No, Koenma-sama," Elsa whispered. "I won't let you die on me." Her fingers glowed with a pale, ice-blue light, and she pressed her hand against Koenma's chest, the light flowing across his injuries.
The demonic assassin laughed, licking blood off its claws. "Mmm, that is tasty! My instincts are rarely wrong, but this is even better than I thought! It's your turn next, little girl," he cooed, gesturing at Elsa. Then, the assassin noticed what she was doing. "Hey, you, stop that! I worked hard enough to fatally injure him; I'm not going to do it again!" Elsa ignored him. "Stop that, I said!" the demon exclaimed, charging at her, claws out.
Koenma opened his eyes again just in time to see the demon charging at Elsa. "Elsa… behind…you…" he said, his voice only a hoarse whisper. Elsa nodded, set Koenma down, and stood turning to face the demon that was so thirsty for her blood. "Don't worry, Koenma-sama, neither of us is dying today. I can handle him alone" she said, her melodious voice reassuring the young prince.
"YOU, defeat ME? My, my, little girl, you must have smacked your head rather hard after my blast. You're spouting nonsense. Here, now, let me put you out of your misery!" Having finished its rant, the demon leapt into the air, claws out, ready to strike…
…and froze solid. "Secret Demon Art: Frozen Wrath!" Elsa shrieked, her voice as harsh and cold as winter, the blue light swirling around her illuminating her every feature, enhancing her glacial beauty to an ethereal quality. Koenma had never seen something so lovely, so deadly, and so majestic in his entire life. Then, it was over. The cerulean light vanished, the assassin demon shattered into thousands of tiny shards. Elsa seemed to shrink slightly in stature, until she was back to her tired, somewhat bloody old self, red eyes glinting in the semi-darkness.
Koenma stared at her, looked at the shards of frozen demon, then back at her. "Whoa…" was his intelligent response to the astonishing thing he had just witnessed. "Come on, lover-boy," Elsa said teasingly. "We've got a demon lord's butt to kick, right?" The Reikai prince blinked, blushing slightly as her remark registered. "Right. Let's go." He stood up, fully healed by Elsa's energy, and walked through the gates of the demon lord's palace.
