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

Damian stared at the guard and asked, "Why are you so happy?"

The guard had yet to stop smiling after meeting Damian. He looked at him and said, "You're a famous enchanter, Damian. I am more than happy to meet you."

"I see. Well, it is a pleasure to meet you too."

It was Damian's first recognition for his work, which felt good.

Damian looked ahead, staring at the building.

It was a mansion three stories and a fence around it for protection. Unlike extreme places with tall walls, it was only a tall metal fence, ensuring people could still see the mansion and those inside could enjoy the surrounding forest.

A courtyard awaited Damian with rows of flowers delivering their scent throughout the area — Damian's nostrils included — making it a lovely, peaceful place.

It smelled like nature, and the tall trees scattered around the area were an invitation to sit down and enjoy every moment of such a beautiful place.
