Chapter 1138: The Harley

Bound and curious, Loki presses Shamrock to explain why his face matches a famous pirate's. Shamrock answers plainly: Shanks is his younger twin, born into the Figarland line, who once visited Mary Geoise before turning his back on his noble birthright to live in what Shamrock dismisses as the grimy world below. The chained giant snarls a promise of revenge for being struck while helpless, so Shamrock, refusing to dirty his hands, frees a blade that becomes the three-headed hound Cerberus and leaves it to deal with Loki. Gunko conjures a bird from her powers, and the pair lift off to hunt one of the giants' children, planning to call in another Knight.

At Aurust Castle, the wounded guards insist Shanks was their attacker, but Luffy flatly rejects it, certain only a lookalike could be responsible even knowing his hero has come to Elbaph often. The guards float the idea of a brother, and Luffy admits Shanks never spoke of family, treating the Roger Pirates as his own. Elsewhere, Franky tours Treasure Tree Adam with Ripley and finds an old mural, while Saul hands Robin the Harley, a text in three chapters describing the world's past, present, and future.

Shamrock discloses that Shanks is his twin brother from the Figarland Family, aware of his World Noble heritage yet choosing the lower world. His sword houses a Cerberus Mythical Zoan, which he sics on Loki as he and Gunko depart to summon further help. Luffy refuses to accept that Shanks harmed the guards. A mysterious man, resembling the figure once seen visiting Crocus, nears the castle. Franky and Ripley examine a Void Century mural on the Adam tree depicting two past world wars and a looming third, and Robin begins reading the three chapters of the Harley.

The Harley frames Elbaph's myths, casting the Sun God's many personalities as differing readings of one scripture, and notes that Nika legends recur worldwide with a signature laughing rhythm. The three passages, dubbed the First, Second, and Third Worlds, speak of forbidden fire, a forest god taming demons, and a sun god dancing the world toward its end, closing on the line that they will surely meet. The cover continues the Yamato pilgrimage serial with a Who's-Who reveal. The chapter belongs to the Elbaph Arc.
