"I... That sounds... Impossib-right..."

*Yeah Yumi still was getting used to this. But then it hit Yumi.*

"So... You said a 'ghost' isn't exactly right for what you are... Does that mean you are one of those... Nobodies?"

*Yumi got into a bit of a defensive stance. If they are truly more dangerous that Heartless, and this guy was one, then this guy is very dangerous.*
Frances
"That's the fun part... You can't. Well the one's with a strong enough spirit you can't." 

Irapx would say and looked at Yumi getting into a defensive stance and nodded. 

"You are correct, I *Am* A Nobody. However, I am on a mission to eradicate Nobodies so I am of no harm to you regular beings."
Jessie
*Psychological zombie, called a Nobody. Wants to rid the world of other Nobodies. Maybe died with single-minded hate for them? Maybe has ulterior motives? Could lie about them if it means killing them.*

*For a fraction of a second, Roxie's smile falters. Or maybe her face simply twitched? It's hard to tell, given how quickly her expression returned to its prior state.*

"I saw a white slithery creature earlier, without the Heartless Emblem. Was that a Pureblood Heartless, or a Nobody?"

*She steps slightly closer to Yumi, subtly reaching for her hand. Whether it's for her own assurance or her friend's, she's not clarifying anytime soon.*
William
*Yumi gets a little surprised when Roxie grabs her hand. She didn't fully understand why, but it did help her calm down just a little bit.*

"You... Seem to know a lot about them. But why not call Nobodies Heartless? They have no heart, but Heartless, at least 'Emblem Heartless', have hearts don't they? At least as far as I know..."
Frances
"That most likely is the case. One's without strong enough will to stay humanoid devolve into those white beings. Heartless typically stay in darker shades and rarely go full white." 

Irapx would go on more before stopping himself and addressing Yumi's question. 

"The phenomena of a Nobody is something rare like I said before. They were fringe cases at best, so Heartless were named that from their lack of emotion in their actions in spite of coming from a Heart and then seeking out more."
William
"That... Makes sense actually. So that thing Roxie saw was likely a Nobody then. And they are a greater danger than Heartless. I have one more question. If a Heartless is killed with a keyblade, it is dead forever right? Anything that isn't one just makes it come back later. What about a Nobody? They have no hearts to release."
