Is That A Wisp?

Krune panted a little, watching the more than 20 Yellow Demon corpses that lay under him. As for Flita, she had killed around 10 while Wristed had killed another 15. Altogether, they had killed 45 Yellow Demons on their own.

Wrister and Flita were beginning to tire out, having fought against such strong enemies. Even though their bodies were still brimming with energy, a tinge of exhaustion was seeping into their systems. 

Krune lightly patted their shoulders, as if to show support. But in actuality, he was seeping some healing energy into their bodies. Since he was touching their shoulders, the light he emitted wasn't visible to anyone else. 

Once he noticed that they were at their optimal conditions, Krune recovered himself as well, now focusing as he tensed up, having discovered a Red Demon far away. As Red Demons rarely appeared on the battlefield, encountering one was hard, not to mention finding one that was the weakest of the lot. 

The Red Demon he found wasn't weak by any means.. Rather, it was stronger than the average Red Demon. Normally, he would have ignored such a strong creature and would have found something else to kill, but upon looking at it, Krune paused in his action, for a moment turning no different to a statue. 

Red Demon!

It wasn't a normal Red Demon, but the one that had attacked him when he arrived at the battlefield right after appearing in Layer 2. He wasn't someone who voluntarily picked a fight with others. But against foes that tried to kill him, he was like a king cobra. He would never forget them,  ensuring that he would slaughter them when he encountered them in the future. 

And this Red Demon was one of such targets. Upon seeing it prowling about, sneak attacking humans to snack upon, and looking at its mockery-induced grin, the very same it used when it jumped on his Cloud Whale and intended to squash him like an ant, Krune's eyes lost their usual vibrance.

Ocean Heart!

Suddenly, the intense sounds of thumping echoed, causing Wrister and Flita to shudder in response, losing their balance as they plopped to the ground. Followed by the echo was the rumbling of sea waves resounding throughout the massive battlefield. 

Krune looked at the Red Demon, causing it to immediately turn his way, startled by the piercing killing intent he emanated. 

For a moment, in its vision, the Red Demon could see the silhouette of numerous dishes behind Krune, for a moment confused by the sharpness of the killing intent and the abstract image of food behind him. 

What it didn't know what the fact that Krune had eaten many creatures, whether sentient or not. And to an angered Krune, it was prey. Unknowing of this fact, the Red Demon smirked. "Interesting brat. To challenge me when you're only at the peak of Tier 4."

It stomped on the ground, flashing through the battlefield, shredding apart Tier 4 humans that stood along its way without any effort. 

"Guys, stay out of it," Krune said, not sparing a glance anywhere except his target. "That red fucker is mine."

"S-Sure!" Flita made eye contact with Wrister, knowing very well that they couldn't intrude upon this fight. Just the sound of sea waves they were hearing caused them to tremble, knowing very well that the god they secretly worshipped daily to was about to unleash his wrath. 

As the two retreated far back, Krune focused, noticing the Red Demon flash before him within a second, carrying a couple of human arms in its hands that it used like batons, smacking his legs. 

Krune guarded with his sword, skidding on the ground for twenty meters from the impact as his sword bent out of shape. Before he could use the Demon Arms to amplify himself, it was damaged beyond use. 

"Hmph!" He threw it on the ground and began to walk towards the Red Demon. For every step he took, the blood on the ground rippled with him as the center. Upon noticing that he wasn't dead with a single attack, the Red Demon smiled, swallowing the human hands it carried with it. "Interesting."

It then flashed before Krune, aiming a punch at his gut, watching in surprise when Krune evaded the attack.

Dreams of the Heart—Ocean Turbulence!

Active Ability—Cloud Whale!

Krune didn't summon his Cloud Whale this time, rather keeping it within himself, making use of its ability to generate air currents. With Ocean Turbulence, he overlaid all five crimson rings of his Ocean Heart into it, causing its power output to increase by five times. 

He also fused Moving Ripple into it, raising his control of the air currents, causing it to react with the blood on the ground, causing the two mediums to mix to raise a blood vapor. This state allowed both his abilities to generate water and air currents to function the greatest. 

With his speed raised to the limit, Krune reached a level where he was capable of withstanding the Red Demon's speed. And when it punched, he evaded, clenching his hand into a fist before slamming it into the opponent's chest. 

His attack didn't even scratch the Red Demon, causing it to scoff in response, "For all the show you put, you're weak."

"You fuckface, don't boast if you can't even touch me," Krune retorted, slamming a punch on the opponent's nose, causing it to bleed. Instantly, the Red Demon digested part of the human flesh it had consumed as it generated some miasma that it condensed in its nose, acting before it could be sucked into the battlefield by the mysterious force at effect in the place. 

As its nose healed, it grinned, slamming a punch right into Krune's face, feeling the impact singe deep into its target. "Trash, you can't even wound me."

As it retracted its fist, grinning cunningly, it noticed Krune's smashed face convulse for a moment before it healed up, soon turning pristine. Grabbing the Red Demon's horns, Krune kneeled at its nose, causing a lot of blood to spill out in the process. "You're no different, bastard."
