Invicinble Colorless Butler

Inside the magnificent floating castle in the southeast of the Clorius continent. Two men face each other. Not two humans, one was the human, the name is Nijisaki Ken with tattered armor. He is a boy summoned from another world as a hero. And the other is...

"This is the end of your evil deeds, Fallen God-King Azael. I will destroy you and your madness."

Yes, the other man wasn't the demon lord that was usually the subjugation goal of summoned heroes from another world. But a god. The gods in their madness and descended to Clorius Continent are called Fallen Gods.

.

"Hehehe... How does it feel to lose your friends one by one in front of your own eyes, hero?" Azael said while sitting on his throne and chuckled.

Ken gritted his teeth while holding back his anger after hearing what Azael said. He held the two swords tightly in his hands. A 7-colored light emitted from his sword as Ken injected his mana into it.

"I won't let the sacrifices of my friends go in vain. I won't let you destroy this beautiful and colorful world." Ken said it firmly.

"Ooh, you think the world is so colorful and beautiful?" Azael smirked as he stood up from his throne. Suddenly a magic circle appeared under his feet and a large green sword appear from it.

Ken launched his attack first. He suddenly disappeared from his place. And appeared right behind Azael. He stabbed his sword right where Azael's heart was. But Azael dodged it with minimal movement.

The attacks didn't stop there. Ken disappeared from his place again and reappeared to Azael's right and left side at once. It was one of his favorite abilities 'Piqmen Clone'. He can make up to 7 clones of himself. One clone slashed at Azael's upper body and the other slashed at Azael's lower body.

"This is interesting, even though you are only a demigod, but your strength equals or even exceeds that of a true god." Azael said and dodged Ken's sword attack while twisting his body into the air through the gap between Ken's two sword attacks.

"Though I'm not a true god like you. But I have the power of my friends who have sacrificed themselves for this world and me." Ken replied calmly while changing the direction of his sword's trajectory towards Azael who was dodging in between his attacks.

"Is that so?" Azael asked flatly.

Azael had no choice but to block Ken's attack with the big green sword in his hand. The green sword in his hand suddenly emitted a pitch-black aura that gave people goosebumps.

Ken narrowed his eyes at the sword Azael was holding. He gripped his sword tighter. And the 7-colored light from his sword became thicker with a splash of lightning.

[Seven Color Thunder]

Ken and Azael's speed increased many times. They move from one place to another without being seen by the eye. Only triggering lightning and rumbling whenever their swords clashed. The pillar of the castle shattered instantly under the pressure from the clash of their swords. Although the pillars of the castle were made of adamantium, the hardest metal in the world. It was destroyed just because they were exposed to the pressure of their fight.

After a few minutes clashed swords with incredible speed. They keep their distance from each other. On their bodies were many sword marks. Even the Divine Dress they were wearing was unable to withstand the attacks of their opponent's sword.

Divine dress is a battle armor in the form of a core that will adjust its shape and size according to the user. Ken's Divine Dress name is 'Hero's Blessing Battle Armor'. It was a fragment of the 'Iron God Battle Armor'.

Azael raised his big green sword with both hands. A thick black aura enveloped Azael like a tornado. Then he swung his sword straight at Ken.

[Breaking the Sky!]

An aura blade with thick mana compression from Azael's sword aimed at Ken with incredible speed. Certainly, the mountain can even split apart if directly hit by this attack.

Ken gritted his teeth at the sight of Azael's aura blade. There would probably be nothing left of him if he was hit by that attack.

"Shit..." Ken clicked his tongue and tried to survive the attack, then he unleashed one of his best abilities.

[Seiryu]

[Manifest!]

Roooooooooaaaarrrrrrrrrrrrrrr.....

The 7-colored mana was compressed to the extreme into a dragon form. It was a dragon that was hundreds of meters long. Yes, this is not a dragon with two legs and big wings. But the dragon in Chinese mythology. The 7-colored dragon circled Ken in the middle and positioned itself as a shield to protect from Azael's attack.

Booooooooooooommmmmmmm!!!

A huge explosion occurred and destroyed part of the castle made of adamantium. Mushroom smoke soared into the sky and could be seen from thousands of miles away.
