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.

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

Claridge wanted to befriend Damian, and that's why he went there without warning no one.

'No one can befriend the enchanter! I will!'

That was the thought Claridge had in mind. Considering his value, he did not want his enemies to have Damian as their friend.

But for him, Damian? Claridge was just the scapegoat to save his ass.

Damian came out of the dark corner, startling Claridge.

"Damn, Damian. Why were you there?" Claridge said, placing his hand on his heart.

With a smirk, Damian said, "Just waiting for you. This is a secret conversation between us, so I don't want anyone to know about it. That's why everything is dark in here."

"Right, right. Don't worry; I didn't tell anyone about our meeting."
