I Am the Ultimate Sword Shadow of Momousagi

Luo Ke transmigrates to the world of One Piece and obtains the Legacy System. From the start, he unlocks the DNF Sword Master: Spectral Shadow legacy. After displaying extraordinary talent with the sword, he is taken in as the sworn younger brother of Vice Admiral Gion.

A Sword Shadow becomes one with a Phantom Demon. But Luo Ke never expected that the Phantom Demon he contracted would be Black Saber!

Gion: My second brother is invincible!

Golden Lion: What the heck! Is true dual-wielding fighting two against one?

Hawk-Eye: Even without that girl in black and red armor, I'm no match for Luo Ke.

Zoro: I'm definitely going to become the world's second greatest swordsman. Right, world's third greatest swordsman, Hawk-Eye Mihawk?

Black Saber: My Master is brave and invincible, handsome beyond compare, and unbeatable. He is the one I cherish most!
