At Sea, I Swear to Kill Every Celestial Dragon

After transmigrating to the world of One Piece, Yikan's parents and younger sister were brutally killed simply because he had interrupted a Celestial Dragon's "pleasure."

When his sign-in System awakened, Yikan embarked on the path of revenge.

Loguetown, Sky Island, Fish-Man Island... He signed in at one location after another, building up his strength. Yikan swore to storm Mary Geoise and wipe out the Celestial Dragons.

The Five Elders: One mistake created the most terrifying enemy in history.

Shanks: No one can stop Yikan's revenge.

Whitebeard: The strongest in the world, and an astonishing young man!

Sengoku: Only by assembling the Marines' strongest forces do we have even the slightest hope of stopping Yikan.
