One Piece: Guilty Crown

Through the whims of fate, he was reincarnated as a member of the royal family of the Germa Empire, an infamous war organization known as the "Army of Evil" in the North Blue.
When the powers of the Logia-type Dark Fruit, the Mythical Zoan-type Bat Fruit in its Vampire Form, and the Paramecia-type Tremor-Tremor Fruit converge into one being, it is destined that the entire sea will tremble beneath his feet!
"When darkness descends, even the light must yield!"
— "The Dark Emperor," Vinsmoke Ichiji.
Apologies for the rough summary. To sum it up: no system mechanics, no mindless power fantasies.
