What has Lakainu done as Fleet Admiral?
The marines may have claimed Kuraigana Island, though we wait for a confirmation.
Jokes aside, Lakainu has obviously spent most of the timeskip coping and seething obviously, as well as being in meetings. But at least we do see that. In wano alone for example:
He sends Aramaki to the reverie
He talks to Kizaru about Big mom and Kaido´s call.
Garp says Sakazuki set the policy on leaving Wano alone
We see this as well
He is on call with Aramaki, most likely giving him orders
He discusses this with other marines, even Sengoku is present, but no Kong around for the issue of 2 emperors uniting.
At the end of the arc, we see Sakazuki in a meeting with the head of navy intellegence and Kizaru about Luffy becoming an emperor, revolutions around the world, etc again, no Kong.
And Oda is doing this in every arc post TS, and the same with Sengoku pre ts. No one is ever shown getting orders from Kong, and even when major incidents are happening, Kong is nowhere to even be seen *discussing* them
