Isekai Mizuki S1 - A World With Demons

Chapter 83 - VS Sinistrius II

April 11th, 9:00 PM

Kokushibo and the other remaining Upper Moons were transported to where they fought Sinistrius last time. Within a few minutes, out of the ground burst the giant cluster of Lower Moons. "I HERE NOW... WHERE MASTER...?" Sinistrius asked, looking for Muzan. When he looked in front of her, he could see the four Upper Moons.

"YOU AGAIN... I NOT WANT TO FIGHT YOU... I WANT MASTER..." said Sinistrius, still looking around. Muzan then connected to his brain, and spoke to him telepathically. "Now, now, Sinistrius, be good," he said, prompting the former to hold still. "Now, I want you to try to fight them again. I want you to see why they should be able to command you. I know you just want to be with me, but I cannot, as I have... *ahem*... important... matters to attend to." Sinistrius obeyed, and turned to the four Upper Moons.

"ME NOT WANT TO FIGHT YOU, BUT MASTER TELL ME FIGHT YOU. BRING ME YOUR BEST!" Sinistrius roared, stomping as he rushed towards them. It was just like last time. Kokushibo backed out, and the other 3 were left to fight. Doma slowed him down, and Akaza landed a suitably hard hit on him.

"STRONG LIKE LAST TIME... I LIKE STRONG..." Sinistrius said, causing a tremor in a large radius by constantly stomping. Muzan then telepathically contacted the four Upper Moons. "Oh yeah, I forgot to mention, Sinistrius has another power aside being a huge mass of power and extreme strength. Watch."

Sinistrius then began to roar, some of his skin tearing off in the process. Magical flames appeared out of the ground and began circling Sinistrius. Now, lava cracks were formed on most of the lower part of his body. "I GOING TO USE POWERS NOW!" Sinistrius said, stomping on the ground, which created flaming explosions from the ground.

"Fascinating, isn't it? Sinistrius may be a musclehead, but he has his own asset of abilities that he knows how to use. Now witness another fraction of his power that I call Elemental Fusion!"

Elemental Fusion (The user deals a moderate amount of harm to themselves to gain an elemental power of their choice. The user can fuse themselves with up to two powers at a time, in Sinistrius's level.)

Sinistrius then sighed, finishing his transformation. "WITNESS," Sinistrius said, roaring once more, as a storm of fireballs rained down upon the three in battle. The three began constantly dodging, and Akaza was throwing fists to fight them off, while Doma created an ice wall to protect them, supported by Kanao's Root Wall.

Air Type (A part of the modified Soryu Style that involves punching the void, which creates a wind blast that can be lethal in close ranges.)

Root Wall (The user summons a large amount of roots from the ground, covering the designated area.)

"How is this thing so powerful?!" Akaza questioned. "I don't bet that's his full power, given that thing has power higher than or equal to ten me's!" Doma answered, trying to support the ice wall by constantly regenerating it each time it melted from the flames. Kanao then thought of a plan to dissipate the storm. "Akaza, sir! Charge up a ranged attack. We'll hold the flames off until you do." Akaza nodded and began concentrating large amounts of power into his fist.

Soon enough, it was fully charged. Kanao and Doma dropped their shields, and Akaza threw the punch, which tore through every fireball it collided with as if it were knives going through paper. The air force exploded upon reaching the core of the storm, stopping any further fireballs from being thrown.

"ME SURPRISED... ME HAPPY!" Sinistrius exclaimed, gleefully hopping. He then bashed on the ground, creating fissures. Akaza hopped on top of one of the pillars, only to realize it was hooked to a trap involving his power. It exploded into flames, sending Akaza flying.

"Damn it! That thing hooked a trap into its pillars...!"  Akaza thought as he landed on the ground, singed but not badly hurt. He reunited with his allies, and took another battle stance. "Is this how it's going to be? Fine, then, Sinistrius. We'll beat you down until it's common knowledge to you that you obey us!" Akaza said, stomping.
