Sign-In System: Starting With Invincible Physique

When the protagonist awakens, he doesn't find himself the protagonist of the story… But a villainous minor prince, a name written in the original tale to be killed early so that the true protagonist's glory might shine. A prince born of noble lineage, yet destined for treachery, madness, and a bloody end. Every step he took in the original story led him to his doom, every decision… merely a prelude to his downfall. But this time, something is different. Within his consciousness, the sinister system of fate awakens—a system that offers him no mercy, that does not reward good intentions. It demands only one thing of him: To go against the course of the world. "Fate can only be broken by defiling it."

Victor Malfoy is the elder Malfoy twin, a transmigrator from Earth, and unfortunately… someone who knows the entire Harry Potter plot. This should have made his life easy. It did not. Victor is stuck with a system called “Most Fortunate Person.” A system that proudly does absolutely nothing—except occasionally throw rewards at him. Yet for someone called “Most Fortunate Person,” Victor is spectacularly unlucky—always stumbling into trouble whether he wants to or not. To find out how his journey unfolds, and what’s really wrong with his so-called lucky system, follow the story. (Note: Except for the OC, I own nothing.)

He thought monsters were fictional. Then he woke up in the world of Supernatural, where vampires are real, demons have better social skills than most humans, angels are emotionally unstable, and the apocalypse shows up more often than rent day. Now living under the name Henry Winchester, he quickly realizes two things: first, the Winchester surname comes with baggage; second, he has a supernatural system that practically rewards him for hunting monsters. Things get complicated when he runs into Sam Winchester and Dean Winchester, who drag him along after discovering he has connections to their family. Between salt rounds, motel research sessions, and near-death experiences scheduled twice a week, Henry starts to realize this world doesn’t hand out power for free.

From the King of Earth and Metal, the Tyrant who controls flames and magma, to the Supreme King of the Supreme, Great, and Greatest Kingdom, or the Dragon of the World, the Dragon of Thousand Faces and Thousand Aspects... These titles are just embellishments on the crown of power of this red dragon. The world has changed because of him. Cultural thoughts and ideologies are his fluttering flags; Mage towers and floating cities are his war fortresses; Countless races and strange creatures are his soldiers; and countless dragons are his commanders; This is a civilization established by a dragon, a dragon kingdom that commands the entire multiverse.

Unfortunately, Leon found himself in the lower caste, labeled the most useless student. To top it off, he was tossed into a class that served as a sanctuary for oddballs and delinquents. Yet, he couldn't care less, as becoming a Magic Knight wasn't his goal. Everything shifted when he crossed paths with Shredica, a woman hell-bent on becoming a Magic Knight at any cost.

She decided to exploit him as a pawn in her ascent through the academy's hierarchy. Yet, unbeknownst to Shredica, Leon was not the complacent, unremarkable figure she presumed him to be. *** Join the discord! https://discord.gg/gt4CDGkpEM

The World of Dhenshin: After a mysterious and intentional attack leaves his house in ashes and his mother—a Master Rank Mage—dead, a young man named Sogha is left with a burning need for strength. Despite possessing no detectable mana in a world ruled by magic, Sogha undergoes years of grueling physical conditioning under a legendary warrior to master the Zen Zhi pillar, the martial art of absolute evasion and phantom-like movement. His journey leads him to the Capital and the prestigious Great Mage and Warriors University, where his path converges with other elite teenagers.
