Magika no Kenshi to Shoukan Maou - 5.1.4 — Strength, the Time It Should be Shown

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!

After reviving unexpectedly, the concubine’s daughter was no longer a coward like before, but a hard nut.

Flamed her up and bullied her?

Come on!

She came from the 21st century! How could she willingly embrace such destiny?

“Since you ask for it, see how I will torture you!”

She punished the scums and struggled against bad minions!

See how the concubine’s daughter Dong Ling would stand up and master her own fate!
