Tricks
"Master, if you wanted to go to the party you could have just gone. You were invited you know." Fran deadpans as he and Mukuro walk in the direction of the Sawada Household. Neither appear as they usually do, though. Instead of their normal appearances, each illusionist appears as a small child who is dressed up in a homemade costume. Fran's costume is a sheet with holes cut for eyes while Mukuro's is a store-bought grim reaper.
"Kufufufu, but that wouldn't be nearly as much fun." He pauses outside of the gate to consider the small house. Even though it is about an hour after trick or treaters would normally be outside asking for candy, the porch light is still on. He laughs to himself as he lets himself and his student past the gate. "Now remember, Fran. This is an exercise in your ability to disguise yourself. If anyone is able to tell who you are you have failed."
"Yes, Master. Though, if I succeed can we attend the party? I'm sure that they'll have something more filling than this candy inside and you aren't the best at providing good food." Mukuro rolled his now brown eyes as he reached for the doorbell.
"Yes, but only if you succeed." Moments later the door is opened by a slightly confused Tsuna.
"Trick it treat!" The pair of 'children' call while extending their bags towards the brunette in expectation.
"It's kind of late to be out isn't it? He asks cautiously while considering them.
"Mama lets us be out as late as we want!" Mukuro says in a demanding voice. "Now give us candy or we'll give you a trick!"
"Now, now," Nana says from the foyer, bowl in hand, "we have plenty of candy so we won't be needing any tricks from tonight, alright?" She lowers the bowl down to a height where they can see what candy they have to offer. The boys greedily take a whole fist-full each. Tsuna makes a small noise of protest, but his mother shakes her head.
"Thank you, ma'am," Fran says as he adds his share to his bag.
"You are more than welcome! Happy Halloween!" Moments later the door is shut and the 'boys' are heading towards the gate.
"That was success, master. Now I'm going back for the party." His outfit falls away into shadow as his form morphs back into his original one. Mukuro follows suit but puts a hand on his shoulder to stop him. His other hand extends forward in expectation.
"Your bag. If you're holding it they may be suspicious."
"I know that you are morally questionable, but I never knew you would actually steal candy from a child."
"You certainly aren't much of a child. But, you also can't jeopardize missions like this. Now hand it over." Fran considers his master for a moment before he concentrates and molds the bag of candy into a phanny pack using his illusions.
"There. Now if you'll excuse me in going to go and get free food."
