You are a part of the Marines, so that means you get to join their Group Chat. Where they discuss plans, or just hang out from the stress that's happening. For it just to be used to communicating in secret, like the Den Den Mushi (Transponder Snail), but to message instead of calling.

The Fleet Admiral, Admiral, Vice Admiral, and the Captains are in here. Right at the moment. Garp (caring for Luffy still) sends a Photoshopped image of Luffy, Ace, and Sabo wearing Marine outside.

Garp: "Look at them, so amazing..."

Sengoku: "Garp, stop sending fake pictures."

Kizaru did a reaction, an emoji below the image; "✨️" as Doll replies to the emoji.

Doll: "Looks like someone at least enjoys them."
