Summary
“Come be free with me.”
Luffy declares, because really, it wasn't in any slightest an offer. And the slave just looks back at him, the fear in their eyes slowly meshing between confusion and paranoia. It was like Luffy had spoken in a language that was completely foreign to them.
(Or, a story where Koby doesn't end up as a chore boy on Alvida's ship. Instead, it's someplace much, MUCH worse.)

Summary
"Are you a ghost or something?” He sounds way too excited about that, but that's not surprising. They smile at him. Their cheeks ache. Their eyes burn. They can still feel their skull cracking open, if they focus hard enough.
“Yeah, I guess!” Smiling, smiling, smiling. The curve of their cheeks fills their voice with something false. “Or, wait, maybe I’m closer to a zombie, actually? Since I have a body, and all.”
“Do you poop, then?”
“Not sure? I mean, this dying thing is pretty new. I haven’t tested it out yet.”
He nods, sagely. “It’s a mystery, then. Hey, do you want to join my crew?”
Smiling, smiling, smiling. His eyes are dark as they track the shape of it. They wonder if he can see the way it trembles. “Shouldn’t you introduce yourself first? Kinda rude to just up and proposition a stranger like that.”
They already know what he’s going to say.
They’ve known what he was going to say since they woke up and saw the hat.
(That doesn’t mean that it hurts any less to hear. That doesn’t make it any less beautiful.)
“I’m Monkey D. Luffy, and I’m gonna be King of the Pirates!”

“…why not sail with me until you figure it out,” he says with a toothy grin. Still feeling unsure I respond, “I don’t think that’s a good idea, I’m not cut out for pirate life Luffy.” He grabs my hand trying to be reassuring, “of course you can Koby if you can handle that ugly lady then you can handle anything,” he says with a smile. “Besides you’ll have friends with you the whole time,” he adds gently squeezing my hand. I look down at our intertwined hands and my face flushes. I squeeze his hand back and look into his eyes, “I want to sail with you,”…
