Aoki traveled to the world of One Piece.
He had Sephiroth's template.
He relied on his own efforts to become a naval admiral, but unexpectedly, he was stabbed in the back by the World Government and the Navy one day, and almost died.
Fortunately, Sephiroth's template gave him Jenova cells, and after decades of repair, he woke up again.
This time, he will return to the sea in the form of Sephiroth's revenge, holding the inhumanly long Tadō Masamune to kill all enemies.
