Kouichi lunged at the Snow Demon Spirit with a loud war cry, his spear, Danzai no Yari, the Spear of Judgement, forming in his hands. He began to wail on the Snow Demon with an incredible and merciless fury.
No. One. Hurt. Koji.
No. One. Hurts. His. Friends.
No. One.
The Snow Demon slapped at him, sending him flying and into a pile of snow that had been created. He stood back up, switching his spear for his Blut Evolution blades. He raised and lowered his swords, creating a red moon before charging at the Snow Demon with incredible speed, not caring to shout out his attack.
Afterwards, he jumped back to avoid the Ice Demon's ice shards, some shredding his clothing as he dodged. He had his blades disappear, a blast of dark energy forming at his fingertips.
"Darkness Spirit's Schwarz Donner!" exclaimed the Darkness Spirit Slayer, the attack coming out of the energy at his fingertips as large amounts of black lightning. The Ice Demon cried out as Kouichi's attack -while not actually being lightning- zapped him over and over again. The dark energies at his fingertips soon began to spread across his entire body, coating him in a strong aura of darkness.
"Darkness Spirit's Schwarz Konig!" Kouichi exclaimed as he slammed into the Ice Demon's body. Both slammed into the snow, though the Ice Demon fell harder than Kouichi did. Kouichi stayed on top the battle, summoning his spear again and driving it into the Ice Demon's body, killing him…
Just like he told himself he would.
Kouichi walked to his fallen friends, going to wake up Zoe first after feeling her pulse. It was still strong, which meant that she should be okay. He guessed that Takuya had protected her -it all had happened quickly- as the Fire Spirit Slayer was more injured than the others.
"Zoe." he spoke softly as he shook her, "Zoe, please wake up."
He lifted his hand as she stirred.
"...! Kouichi…?" she sat up, looking around and noticing the others, "...! What happened?!"
Kouichi frowned, "We were attacked. I managed to defeat the threat, but you guys were injured. Do you mind healing the others?"
"No, not at all." Zoe quickly set to work, healing the others to the best of her ability. Kouichi kept a lookout, just in case they were-
"Ahahahaha… Hahahahahaha… Hahahahaha… Did you think I was finished…?" came a familiar voice. Kouichi's eyes widened.
"I'm not done yet…" continued the voice. Kouichi stiffened, and saw out of the corner of his eye Koji -now awake- move closer to him. He heard Tommy shriek in fear.
This battle is no place for a kid as young as him… Kouichi found himself thinking. Of course, he himself was only nine, but that didn't matter in this situation.
"You're not done yet?!" exclaimed Takuya, keeping his determination strong. Zoe stood up with the Fire Spirit Slayer.
"We'll have to beat you down again." she spoke, even though she knew they wouldn't be able to use their Secret Art.
"How can you…? You're too weak now!" Cherubi laughed, appearing in front of them.
"That doesn't matter." Koji spoke, "We will defeat our enemy… We won't lose to you!"
I feel like this chapter is too short... Kouichi is already really strong, so the fight really wouldn't need that much effort from him.
Next chapter is the True Final Battle against Cherubi!
