A guard pov of the Impel Down arc would be pretty lit...

In the style of One Piece fan letter. Except everything just spiral into chaos.

Maybe one pov is a guard, another is a Newkama revolutionary, and another is a prisoner, and the last one is one of the navy sailor that got transfer from Momonga ship into Impel Down duty.

So the navy sailor pov could cover the arrival of Hancock, to the leaving of Ace.
