DxD: Building A Demon Clan From Scratch. - Chapter 99: Isayama Yomi (BONUS)

King of Harem, Pioneer of All, R-18 Story

My name is Mike Tyson. I was a normal dude that had an abnormal death. I was lucky enough to get reincarnated in another world.

This is earth, but alternate earth or real? I don't know. But I know that I was born with the fate of a protagonist. Unsuccessful in awakening my innate talent, I spend two years in my middle-school.

But this year, everything changed. I awakened something, and not just an innate ability but also a unique ability. That was the true start of my life.

A life that I feared became reality. My fate was in my hand, but the fate of my little dragon was in the hands of the system. Spreading the legs of women in bed, I found a new way to gain strength.

Heavenly Maidens, Supreme Fairies, shave that cave of yours. My little dragon will fly from one cave to another until it meets the destined cave.

Embracing the power given to me, I let the beast inside of my soul go wild. I was no longer restricted by anyone or anything.

The title does not represent me, I represent the title. Spreading the legs of hundred women, I will ascend to that title and become the one and only 'God of Sex'.

Standing in front of a creature with a dark face and red scales, I broadened my chest and asked “I have talent, looks, money, women, power, and little brother. What gives you the confidence to challenge me?”

Every little detail including name, identity, is fictional. They might be relatable but please don't relate them.

Harry Morton was born in an age where magic and mana ruled everything.

He was unable to awaken his affinity and to make things worse he was born with a broken mana core foundation which meant he would never be able to create or develop a mana core. Since he couldn’t create a mana core, he would never be able to draw mana—not even the slightest strand.

He was the first person to be born without a mana core foundation, the only one with the inability to draw mana. Due to this, he was regarded as trash by everyone: his parents, his friends, the society and even the academy he attended.

It was until one day, during a mana beast attack when he almost lost his life.

He saw a strange white line rapidly moving downwards, towards him. Unbeknownst to him, the white streak went into his body.

When he woke up the next day, a strange message appeared in front of him.

DING!!

[Welcome Host to the Manaless mage system]

However things didn’t end there, a lot of secrets were revealed to him, things greater than he could have ever imagined.

Now that he had the power, would he save humanity?

Follow the protagonist in his journey as the Manaless mage, as he rises to the absolute top!

Ethan Carter never thought much about heroism—until the night he pushed a girl out of the way of a speeding truck and felt cold steel and shattering bones instead of pavement. He expected to die. Instead, he woke up in a hospital, completely healed, with a strange blue screen floating in front of him.[System Activated.][Welcome, User. Your journey begins now.]At first, he thinks he's hallucinating. But when his body starts changing—his strength skyrocketing, his reflexes sharpening—Ethan realizes this is real. The System grants him quests, skills, and rewards, pushing him to break human limits. And yet, there’s more. Locked away in his interface is something called *World Travel*—but it remains inaccessible, its conditions unknown.As he grows stronger, Ethan catches the attention of powerful forces—some eager to recruit him, others determined to stop him. And amidst the chaos, women drawn to his power and charisma begin to enter his life, each with their own mysteries.But one question haunts him: *Why was I chosen?*The answer lies beyond this world. And when the time comes, Ethan won’t just step into new worlds—he’ll conquer them.

Renji was nothing special. No wealth, no fame, no grand ambitions—just a 23-year-old gamer wasting his days in a cluttered apartment, escaping reality through the immersive world of Eternal Realms. In the game, he was powerful, respected, a leader—the elven king, commanding armies and shaping the fate of kingdoms. But outside the screen, he was just another nobody.That all changed the moment his world shattered.What started as a routine gaming session took a terrifying turn when his screen flickered, reality twisted, and an unnatural force yanked him from his chair. When he opened his eyes, he wasn’t in his apartment anymore. He was in a world of towering forests and ancient magic. He was wearing regal robes, a golden crown resting atop his head. And before him stood four elven women, their expressions filled with reverence and concern.They called him King.Memories not his own flooded his mind—battles, alliances, the weight of a kingdom’s future resting on his shoulders. It wasn’t just a game anymore. This was real. And the fate of the elven race now depended on him.But Renji wasn’t a hero. He wasn’t a warrior. He was just a gamer who had no idea how to rule a kingdom, let alone survive in a world teetering on the brink of war.But Just as he was pondering on it a mechanical voice sounded in his mind.
