Prologue.

An ominous-looking black-haired handsome demon floated in middle of somewhere in space with his eyes closed, while his wrists and ankles were bound by golden, divine looking chains that had seemingly appeared out of nowhere. He was 7 feet tall, with broad shoulders and a lean, muscular, chiselled, and ready for combat body, and he had "C"-shaped horns that protruded out from the corners of his forehead. His entire left arm and right forearm were bandaged in black coloured bandages; though they appeared to be bandages, they were actually the skin of the demons he had killed, and he had even worn the clothes he had made from the rest of the remains.

In front of him was a massive eye. The eye was so massive that he seemed like a mud grain in front of it. The iris in that eye had a random stroke of all the colours in existence; it seemed so ominously pulchritudinous even as it glared at the man as if he were a persistent bug.

<You shall remain here until you perish, as I, the eye of the laws of casualties, declared you as an "existence that mustn't exist."> The eye of the law of casualty casually mentioned.

The demon in the front smirked with his eyes closed, and his smirk slowly widened, revealing his fangs. He gradually opened his eyes, showing off his abyss black sclera and pure white iris with vertical black slits, and then he opened his mouth, "You said the exact same thing the last time, and yet here I am, back in front of you." He said with his eyes burning fiercely in arrogance.

<Your existence shall be erased.> The eye of the casualty asserted.

"I don't really care, so" the demon gritted his teeth in annoyance, glared at the eye, and "fuck off." He cursed at it, and in that instant a 100-foot-wide footing materialised beneath his feet, seven pitch-black coloured portals manifested around the footing, and seven goat-horned demons with their own unique appearances walked out of the portal and glared at him with unfocused eyes.

"So, it's going to be like this this time too, I see." He mumbled under his breath, and the grin on his face turned savage.

"Authority of the Mana Parasite." He mumbled, and with disgusting noises, red and blooded intestine-like flesh materialised above his arms and formed two-foot-long blades on his forearm, one on each.

"It has been a long time since I fought with them." He mumbled with a wide grin and zoomed towards the seven demon kings in front of him. He was shocked when he saw more and more of them walk out of the portals before rushing together at him, and it wasn't long until his shock turned into excitement.

"Hahaha."
