User blog comment:Observer Supreme/How would Kizaru and Aokiji operate if either of them were Fleet Admiral?/@comment-2001:8003:1172:2900:F89B:8A28:7ADB:BB90-20170715155336/@comment-25400375-20170715160511

Issho probably would know what to do best, so long as he's got a helpful assistant to help with paperwork and doesn't antagonize the Warlords all the time, but from what I understand, he wasn't a Marine until Sakazuki took office as it were.
