Yuusei had been working on her D-Wheel since before Jack had come back in, and he couldn't help but feel irritated.
Ka-chk. Ka-k…
Really… with the party celebrating the WRGP only in a matter of days, he would have thought that she'd be a bit more prepared! But no. He hadn't noticed her doing anything other than what she normally did!
Even Aki had gone out and found something new! It seemed like all of them had, apart from Crow - and wasn't that just like him, not to care - and Yuusei.
"Oi, Yuusei."
"Aa?"
"You have sorted out what you're going to do for the party, right?"
"Aa," she said, carrying on with an expression of concentration.
"Even Carly's got something."
"Mm-hm."
"I'm sure if you're having trouble finding anything, Aki could help you."
"Un. That's right…"
"Crow's probably not going to bother, damn it-"
"Ah-hn…."
"What?"
Was she… was she even listening to him? After all he was trying to do?!
"…Oii….. Yuusei…" He grabbed at her, making her jump.
"Eh? What-?!"
"Look. Crow, I can handle. But I'm not having you put no effort into this!"
"Ah… Jack… you really don't have to…"
"Hn!"
"Crow isn't going to like it."
Although she wasn't, at least, fighting back too much. Apart from shoving him off of her, that is. And now, after dusting herself down, he'd grabbed at her arm this time and had started to pull her towards the doorway.
"Crow doesn't have to like it. I, Jack Atlas, refuse to allow my younger sister to appear at such an event improperly presented!"
"Ahh… Jack…"
…
The dress she ended up wearing was a dark blue, and brought out her eyes. It also allowed for a good range of movement, something that became very useful when she ended up having to duel later that very night, after reassurances that she wouldn't have to do that very thing.
Crow, as predicted, was not impressed… with either of them. Jack, for dragging Yuusei out for it, and Yuusei for going along with it.
…
AN: Reminder that this is Jack being Jack, and Yuusei… really can't care either way as long as she can move around and ride a bike. Pairings didn't come to mind after this, even. I'd just seen a fanart that inspired this scene, months passed, and then I was inspired to do more - I'm even reposting it here as in the order I wrote it.
