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

After the two nights, Damian earned himself 40 Erotic Coins! That was a high number for a started like he was.

Damian browsed through the abilities section, trying to see if there was something that caught his attention, but there wasn't anything fancy about the number of coins he had.

He also wanted to first get good at his Telekineses ability, and then go buying others. It would not make any sense to have multiple abilities yet suck at all of them.

But the System had many things, not just abilities. Increase his attributes was something Damian could do, like leveling up a character of an RPG.

"Let me check the items first," Damian thought.

The System also had a shop with many types of items, ranging from offensive to defensive. Most of the things in there were enchanted swords, daggers, bows, and rings. Damian did not know about its effects.
