Darrow travels to the world of One Piece and becomes the younger brother of Roger's wife Rouge. Fortunately, Roger has not yet conquered the Grand Line, so Darrow still has time to change his sister's tragic future.

The story begins with the crew's adventures (partially original storyline + extensive references to the old era in the manga), and after Roger's death, they become one of the Four Emperors and vie for supremacy.

I awoke from a dream, incomprehensible murmurs echoing in my ears. Forgotten myself, lost my past. Looking around, I realized I was in hell—explosions raged across the azure sky, bullets ravaged the streets like a torrent, and war burned constantly across this land. The aliens who lived here possessed seemingly fragile yet fearless bodies, forming gangs for their own purposes, killing each other day and night. Then, they discovered me. They called themselves students, told me this place was called Kivotos. They also called me—Teacher.
