In the World of One Piece: I Unleash the Thousand-Year Blood War!

He transmigrated to a thousand years before the age of pirates and founded the Invisible Empire. In pursuit of even greater power, he feigned being betrayed by his subordinates, whom he had granted the letter "Y," and fell into a deep sleep amid the rebellion stirred up by the Space Pirates.

After a hundred years had passed, erasing the blank century from history, eight hundred years had now gone by, and the sleeping King of the Quincy was gradually regaining consciousness...

But who could have guessed that the former Schrift "Y" would become Imu, and even use the Quincy bloodline factor to create Devil Fruits!

Would the Connecting Kid "J," Joiningboy, become Joy Boy and gather the remaining Quincy to found the Great Kingdom and oppose Imu?

The world changes too fast...

But everything in all the worlds exists for me to take!

The Sternritter, granted the power of the "Schrift"; the Empire's Thirteen Squads, granted the power of the "Holy Blade"; the Ten Espada Legion, granted the power of the "Holy Soul"; and native fighting forces from other worlds, each established in turn. Go forth and conquer for the Empire!

We... are feared because we are invisible!
