The Peak of Pirates! Starting as a Roger Crew Intern

The pinnacle of piracy! Starting as an intern on Roger’s crew

[Arrives at Raftel from the start] [Shanks and Buggy’s lifelong enemy] [Black gun, red hair, clown king] [Observation killing + advanced Conqueror’s Haki + Seastone bullets] [A Paramecia user who cannot move] [The supreme big pants] ...

Looking back on Ous’s life as a pirate, his achievements are countless. But if one were to speak of the true turning point of fate, it would have to be the moment in childhood when he shouted with all his strength:

“Kid, why do you have to get on our ship?”

The man who hid the great treasure at the end of the sea, the Pirate King Gol D. Roger, smiled at Ous before him and asked,

“Hahaha... Of course it’s to turn this world upside down!”

After he boarded the ship, Roger was shocked to discover that he seemed to have gained another monster-like kid as a crew member.

Monster-level strength far beyond that of a giant race? Innate awakening of Observation Haki!?

And so, Ous, who successfully boarded through extremely high emotional intelligence, showed astonishing learning ability, mastering Haki, marksmanship, swordsmanship, and hand-to-hand combat, while also becoming the closest friend of Shanks and Buggy.

...

On an ordinary day, an unwelcome guest came aboard the newly departed Sunny. Everyone looked together at the man carrying a black gun, a man who existed only in legends.

“Want to know what One Piece is? I’ll tell you.”
