One Piece: Everyone, Bow Before Me

[Satisfying power fantasy] + [Overpowered background] + [Invincible] + [Multiple heroines (don't read if you dislike that)]

"I am Imu's greatest creation, a weapon made to slay gods."

Golden hair crackles with lightning and fire, while blood-red eyes reflect a burning Mary Geoise.

Ianchi, a war machine made by combining Imu's blood with the genes of five races, was meant to be born in the Holy Land and destroy the world. But thanks to Vegapunk's wager on humanity and Makino's tears, he became a boy sipping juice in an East Blue tavern.

As the resentment of his Lunarian blood scorches his soul, and the Three-Eye Tribe's visions foretell the world's ruin, he tears off his shackles:

"Celestial Dragons? Five Elders? How laughable... Your corpses are nothing but steps leading to my throne!"

He wins the Empress's pride, drains the Marines of their loyalty, and fishes for mermaids' tears. With beautiful women of every race as his blades and the Red Line as his monument...

This is the ritual that ushers in a new era: Everyone, offer me your flesh and your love!

Yet when he sees Imu's disturbingly doting smile and pupils transformed into blood-red hearts, he is left completely stunned.

What? I'm the one who's been funding this all along?!
