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!

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

The festival was blooming with happiness. Damian walked inside the city, ensuring that the people saw him - the one they called the hero. A few commentaries, especially from the married ladies, were a little odd.

"Is it a good thing for me to be able to hear everything or not?" Damian wondered.

Anyway, he stayed at the festival for a while, drinking mugs of beer and dancing with his friends around a massive campfire the locals had built in the city square.

A few adventurers who had been out from Lemoria, only returning recently, had no idea what the reason behind the festival was.

"A festival for a single person? How awesome can this person be!"

"Well, he is an enchanter with a shop in the city, so you might as well go meet him in the future."

Aurora, Magnus, Vanessa, Natasha, Serana, and Shareva participated in the festival. After drinking a lot, they decided to head back to the temple. That place was their home, after all.
