Barzab Seven, a weak and overlooked cook from a humble village, is unexpectedly recruited by the legendary Pirate King Roger—only to discover he’s a transmigrator granted a powerful Multiverse Trading Platform. While his body remains frail and his combat skills nonexistent, Seven thrives by collecting legendary artifacts from the Roger Pirates: Roger’s straw hat, Whitebeard’s beard, and even Blackbeard’s teeth—all traded for system points. When Roger is publicly executed in Loguetown, Seven seizes the moment to devour the Gura Gura no Mi, unlocking devastating earthquake powers and finally gaining true survival strength.

Now hunted by CP9 and the World Government for being the last known crewmember, he escapes with the world’s greatest swordsman, Mihawk, and plots to build his own crew. With the Great Pirate Era just beginning, Seven must outwit Marines, recruit legends like Buggy and Jinbe, and master his newfound power—all while hiding the truth: he’s the only one who truly understands the nature of Conqueror’s Haki. But how?

He never trained it… because he didn’t need to.
