- Description from 69shu

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

After living a hopeless life and getting exploited to his breaking point for his unique powers, Mithras is diagnosed with a terminal illness, about to die a brutal death when he is murdered anyway by his boss for refusing to betray his sister.

Reborn as the Human Aphrodisiac, and now equipped with a lewd system, Mithras is determined to use this second chance to avenge his past grievances and breed his boss' slimthick mom with a million babies!

But there are two problems:

1) He is now unkillable, but can only heal his injuries and sustain his immortality by drinking breast milk or love juice!

2) The System has not only turned his entire body into an aphrodisiac but also made his cum into a five-star delicacy that can not only improve the beauty of any woman he has sex with but also turn them into peerless warriors!

“Mithras, we want your secret juice!”

“Ok. But how much are you willing to pay for it?”

[Ding! Ding! Ding!]

Surrounded by beauties chasing after his secret juice, and persecuted by their greedy admirers, can Mithras protect his secrets and stay true to his past life's principles, or will he indulge in the temptation of his new powers, becoming the Harem God of a generation?

Spoiler Alert: Of course, he will!
