After the War, many things changed with the Marine.
There are new unknown Admirals, but does anybody know what Sengoku's new position is?
(After timeskip, he doesn't seem very serious any more)
I found this in the Wiki:
Sengoku the Buddha was the fleet admiral of the Marines during the first half of the series. He was the successor of Kong and the predecessor of Sakazuki. He was also one of the major figures along with Whitebeard, Shiki, and Monkey D. Garp during the times when Gol D. Roger was still alive, and still continues to be in the present, even after his resignation from the Marines. Sometime during the timeskip, he became a General Inspector.
Does anybody know what "General Inspector" is?
