[ Somewhere in an alternate dimension where the Kirino stuff didn't happen...
Guess what leaked out. Yeah, the word of when Giorno's birthday was. Asahi knows Bianca, so it's not too weird that she'd eventually hear it through that girl - even if it was sort of late. But it's difficult to count days in Asgard either way, so it's probably not like she could get it spot on either way, right? Spring started a while ago, so around now should be okay enough - as far as she's considered, either way. She needs to throw a birthday party for him sometime, after all, even if it's just the two of them. (Or, for some weird reason, she actually felt like she specifically wanted it to be just them, but.. she tries to push the thought down.
So Giorno might hear someone knocking on the door of his room rather loudly. Or rather, the sound is coming from too low to be knocking, it's probably more like kicking.. ]Yo, Giorno! Open up already!
[ If he bothers to open the door, he'll find Asahi. Except it's more like a pile of board games with a different box on top of it and Asahi is behind it, judging from the pair of legs sticking out from under it. ]
