NOT AU. ... PROBABLY. Also as I assume you may have noticed I decided a bit ago that I should show you whatever I write that day that isn't origfic (not that I often write origfic) and if I don't like it much I pm instead of vm >D
Rokudou Mukuro has a lot of bad habits. This isn't particularly a surprise to anyone, (though Chrome might argue whether some of them are quite bad rather than simply -- Mukuro-sama's) but unfortunately he enjoys following a few of the more ... eccentric ... of them.
And this is how Gokudera Hayato ends up sitting in the bathroom with a bottle of lavender nail polish and a probably-insane illusionist in his head. To be fair, it's not like Mukuro wandered off in his body to buy said nail polish; Gokudera had thought it might be useful somehow in some vague point in the future. He does not think that now.
What he is thinking now is something much simpler: Get the fuck out! He mentally flips the illusionist off, just for good measure.
Mukuro does the mental equivalent of taking down the drapes and replacing them with newer, more brightly coloured (blue, of course; it's not as though his hair colour is natural) ones. "How rude. I'm doing you a favour, after all."
How?!
He pauses briefly in his redecorating of Gokudera's mind (mostly he focuses on inflicting Mukuro cooties on everything and looking for amusing blackmail material) to check if the nail polish is dry. It is, but it's faint; he applies another coat, careful to not get any on his -- Gokudera's, really, but his at the moment -- fingers. "Aah, isn't smoking detestable? Your nails were so stained, I had to help."
His current host remembers that he does own nail polish remover (it's quite inflammable, you see, and often handy; Gokudera believes in being useful at all times), so Mukuro's strange decisions at least are easily reversible, so Mukuro carefully pulls open the cabinet (wouldn't want to stain it with nail polish, after all; he is magnanimous enough to not intentionally increase Gokudera's rent), takes out the bottle, and pours it down the drain.
WHAT THE FUCK ARE YOU DOING, Gokudera says, polite as ever.
"Kufu, I'm simply removing a fire hazard." Sense of aesthetics satisfied, he checks that Gokudera's nails are dry (they are), and leaves. Happy new year, he says as he returns Gokudera's body to him.
"Fuck off," Gokudera says, but he's already gone.
