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!

The MC will not start as a villain, but something will shift his mind in the future.

All-in-One System: All I Need is Erotic Coins

The student who was following Damian was from Orton's Superhuman School. At first, Damian had no idea why someone from that school would follow him.

He never went there before, and he was not even going to participate in the tournament, so there was no reason for them to go after him, yet someone had!

The answers would finally come to him with the student tied to a chair and willing to let Damian peek inside his mind. He placed both hands on the boy's temple and activated his Telekineses, searching for information inside the mind with the help of his passive-enhancing mind control.

It was impossible to get a clear answer to why the student was doing what he was doing, but the images that flashed before Damian's eyes were easy to understand, and the face of someone he knew appeared.

"Joffrey? Bastard. Again?"
