Devil Slave (Satan system) - Chapter 19 Points Control Everything...

The day dungeons appeared on Earth, everything changed! From ordinary beasts to monstrous ones, attacks were common throughout the globe, and no one was safe.

After countless studies using these beasts as subjects, Humankind developed a serum capable of awakening incredible abilities in humans, leveling the battlefield.

With the serum came heroes and villains, those who wished to use their powers for good or bad.

The Garmony Upper School was a place for the elite with the sole purpose of creating heroes to fight the villains and explore more of the dungeons after the beast attacks increased for no apparent reason.

Damian Romero, a youth who received the serum after turning 18, yet got no unique ability. It was not uncommon for one to not receive power, but it was still a blow to one's pride.

He went rogue after the news, drinking alcohol and having a good time with women, and it was at that moment, when he was putting his toy to play, he got a surprise.

[All-in-One System Unlocked]

Damian's unique ability was a system with multiple functionalities, but after he studied it, it seemed this system worked with a different type of coin called Erotic Coins!

Improve his body? Buy any item or unique ability from his system's store? All Damian needed was Erotic Coins, and he knew how to earn them!

Somehow, the protagonist Kim Jin possessed a rich pushover extra in a novel who was exploited by the villainess and then met their demise together.But there’s no way Kim Jin would let that happen! He immediately defeated the villainess and locked her away. After that, the only thing left was to steadily enjoy life in this world while investing and extracting profits using his knowledge.But why… the more he punished her, it seemed that the villainess he had captured began to cling to him too much?

[WSA 2025 ENTRY]“Seriously? Of all the people I could’ve become, I get stuck as him?”Damien, a shut-in who spends his days cursing his favourite authors for every plot twist he didn’t like, meets his end at the hands of a mysterious woman.Just when he thinks his life is over, Damien wakes up as Alden Draven, an extra character inside his favourite novel.You know, the kind of character who shows up for one chapter, says nothing important, and dies tragically in the background to move the plot forward. Yeah, 'that' guy.And guess what? His death is scheduled to happen in the first few chapters.But just as he resolves to not die and change his fate, he notices something’s off. The plot is... wrong. The characters aren't acting as they were meant to be, and the plot is all messed up.“This wasn’t supposed to happen; the stupid hero was supposed to fail miserably right about now! Is it just me, or did the entire plot get hijacked?” He muttered as it hits him....“F*ck! ”Is there another transmigrator?”And if that wasn’t enough, there's a yandere girl, one of the characters he's meant to interact with, who’s developed an unnatural obsession with him.

Every time he dies, Ethan Hill gains a little more power.Earth was chosen for Integration, but Ethan knows from the second his Trial begins that the Integration is a lie. These creatures giving Earth the 'honor' of access to their Interface want something from Earth - he just doesn't know what.Now he's trapped on an alien planet and lost in a time loop, fighting for strength and for his own humanity.One thing's for sure: He'll die as many times as it takes to tear it all down.
