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!

After the ethereal older man stopped talking, he vanished, and a blue portal appeared in front of everyone present. It looked similar to the portals one would use to traverse the dungeon floors.

She wanted to know Damian's opinion. For her, Damian turned from a stranger into someone she could trust, someone that saved her life more than once.

"Why not? This Skyfall Tower is a new mystery we can explore inside the dungeon, and I think we are the first humans from Earth to get here," Damian said.

That was the question he still had inside his mind: why now? The tower could have appeared at any time, especially considering humans have been exploring the dungeon since long ago, yet it only appeared now!

Lucy and Luna were also down to explore it, "let's go see what's up with this place."
