One Piece: Onmyoji of the Grand Line

The Grand Line is a sea area that is always full of magnificent waves. I witnessed the birth of the Rocks Pirates on Beehive Island, and the destruction of the Rocks Pirates in the Valley of Gods. I saw the three legends grow with my own eyes. Under the storm, I saw the naval battle of Ait Wall that shocked the world. I witnessed Roger's climb to the summit and also his execution. I saw a lot of trend-setting people going to sea, and I saw the Yonko, the King's Shichibukai, and the Navy Headquarters. Finally, I saw the arrival of that extremely evil era and witnessed the birth of the Sun God. When the world changed completely, people looked back and found that the Onmyoji seemed to have changed nothing and yet seemed to have changed everything.
