One Piece: I am Imu - Chapter 341: When Sand Meets Lightning

One day, a silver-haired goddess appeared before him.“Heaven-Defying Star. The one who goes against fate. The sole savior of a world doomed to end—”What the hell is this woman even talking about?“You must be the Regressor.”“… What?”No, I’m not.

The notorious imperial court lackey and the meritorious military general were well-known for their mutual dislike, a pair of arch-enemies set in stone. Who could have foreseen the unexpected change in the winds of heaven: the general injured on the battlefield, both legs disabled, and even forced by the emperor to marry his nemesis.  

With one marriage edict, two people with mutual hostility are forced to marry and live under the same roof. Yet after these long days together, they come to the realization that this fellow is not truly devoid of any saving grace/unattainable and high out of reach.

“You’re not taking me to bed. Ever.”

Akun, along with his classmates, was summoned as heroes by a goddess to save the world from the demon king. Akun, doubting he has what it takes to save the world, asks the goddess to send him back. Little did he know that this request infuriated the goddess. “How dare a mere mortal go against my will,” she thought to herself while maintaining her facade. She opens a portal for him to go back. Little did he know, the goddess had something else in store for him. As he passed through the portal, his soul was separated from his body, and he fell through the sky and earth until he landed in the body of an ant in the godforsaken forest.
