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 feeling of Wendy's body rubbing against Damian's was pleasant, something Damian would not deny or act shy about it.

She was not a shy person either, and the combination was a dangerous one, yet nothing happened. Wendy was more focused on getting the hell out of that island, and not having fun around.

Damian did not mind that, and preferred to focus on the mission, too. It only had been a few days that the accident with the plane happened, but he could not wait to leave the island, and return to his usual routine.

So he looked at Wendy after their hug ended and said, "come with me. We have a hidden cave, and that's where the others will come to meet us. Probably tomorrow,"‌ Damian said.

They left the beach, swimming toward the hidden cave. Once Wendy passed through the gap to enter the cave, she could not believe what she was seeing.

"This place is incredible!‌ You guys made all of this?" Wendy said.
