JJK: My Inner Demon is My Romantic Rival

If you like a character, become them. That's what Shiki thought, until she transmigrated to Teyvat while cosplaying at a convention. Opening her eyes, connecting to the Ley Lines, and directly perceiving the death of all things. As long as it's a living thing, even a God, I'll kill it for you to see! -------------------------------- Read up to chapter 40 in advance at p@treon

"Special Admission, Rank 1." That was the title on the golden invitation I threw into the trash three months ago. Back then, I was the Crime Lord of Oakhaven. I had money, territory, and an ego that touched the sky. Why would a King lower himself to attend a school? I was arrogant. I was foolish. And I paid the price. It took less than an hour for a single knight to turn my criminal empire into a graveyard. He didn't just defeat me; he ignored me. I was an ant beneath the boot of a god. Broken and desperate, I used my last asset: a golden letter granting me entry to Zenith Imperial Academy as "Special Admission Rank 1." It’s a lie. I’m not a prodigy. I’m a fraud with no foundation, surrounded by the strongest heirs in the Empire who want to see me bleed. I can’t cast their spells. I can’t hold their weapons. But I can steal their lives. My Authority is [Usurper]. While they study theory, I steal reflexes. While they practice honor, I copy trauma. I am not here to learn. I am here to hunt. My targets are the "Four Calamities"—four women who hold powers strong enough to rewrite reality. They think I’m their peer. They don’t know I’m the parasite waiting to hollow them out. I’m going to make them mine. Discord: https://discord.gg/FK9GfrSjtb

The story follows a powerless human, Aruford, living in a world ruled by Hexarchs(or can be called myth gods), beings believed to protect humanity through divine authority.

Let's if he can win or if fate is something else..

First, he was drawn into the world of Reverend Insanity—only to be yanked out and thrown into the Main God Space. The setup felt familiar, deceptively so. A trap disguised as a trope. Emerging from the Gu world and stepping through countless others, Zhou Ming carries a single Gu insect within him. It does not whisper. It does not obey. But it watches—and waits. Now, with nothing but an unreliable bug and a lifetime of cross-world survival ahead, Zhou Ming

Regrets became evident on Reina’s face after he had killed his enemy, Gen Yamashita, a young scientist who created the zombie virus that spread across Japan. He knows that he is the one who causes the death of his parents, but he soon realizes that vengeance is not the way to go. Instead, he became a monster like Gen, and he was devastated by it. Now, he decided to save Gen from his death, and after that, he became depressed and blamed himself for making the virus outbreak worse. It seems that he would be a broken person full of regrets. But, he will not last long in his painful depression. Gen came and reconciled with him, renewing their wills to live life again. Now they are racing against the clock to reverse Gen’s mistakes that wreak havoc across Japan. They will not do that huge and seemingly impossible mission themselves. Two of Gen’s subordinates, Arashi Hoshikawa and Nato Hokawa, and a pair of twin young women, Mara and Martha Buenavista, will accompany them in their mission, alongside Gen’s organization. Will this be a golden ticket for both Gen and Reina to a better life and future?

One day, a mysterious package arrived at my home. Inside was a quantum computer. Its performance far surpassed the technology of modern humanity. With it, anything could be hacked. Even the “Akashic Records,” the culmination of all knowledge and technology across the entire galaxy.

Aku was not the hero destined to save the world, nor the princess destined to be rescued. He was the demon king. Born without a name, without form, without freedom, predestined to die at the hands of the hero from his birth. However, Aku decided to defy fate. He took over the hero's body to find his freedom. It was then that an angel spoke to him, believing he was the hero who had failed to defeat the demon king. The angel told him that countless worlds and countless demon kings existed; those heroes who failed their mission were sent to an academy to amend their mistake. Now Aku will find himself caught up in battles with other demon kings and wars in other worlds while deciding whether to choose the path of good or allow himself to be consumed by darkness.

In the monster-plagued Heian era. Minamoto no Yorimitsu was branded as a Dark omen and sold into slavery by his own kin. For years, he was the plaything of the sadistic Minakaze clan, until they cast him into the deep mountains as expendable fodder for Yōkai hunting. But he did not die. He was rescued by a legendary mountain witch, Yorimitsu spent years forging his body and mastering a terrifying, dormant sorcery, all for revenge. Yet his sanctuary became a slaughterhouse when his master was consumed by demonic rot. In a final, tragic confrontation, Yorimitsu’s master traded her soul for his own. Now, Yorimitsu has opened his eyes to find himself ten years old again, about to be bound in chains, back in the carriage that sold him to hell. With his memories of a grandmaster. He has the hunger of a demon. And this time, he will not merely survive Yōkai or the clans that betrayed him. He will hunt every demon, break every chain, and carve a path of unity through blood and fire until Nihon itself is freed and whole beneath his banner.
