I'm the Yonko Van Oka, Blackbeard Is My Little Brother.

Traveling through the world of One Piece, he became Van Oka, the leader of the Blackbeard Pirates, and also awakened the limiter system. One shot and one cookie man, just the basic operation. My bullets can penetrate space, and my bullets are as powerful as nuclear explosions. There is no enemy in the world that I cannot defeat with one shot. If there is one, then use two shots! One day, the button was opened and the rough man with his belly exposed found Fanoka. Before he could speak, Van Oka took the lead in issuing an invitation: "Join my Van Oka Pirates and become my right-hand man, Blackbeard!" This novel and its characters are purely fictitious.
