Kakashi arrived on the rooftop in a reasonably timely fashion, having marked the date on his internal calendar when Rin had informed him she'd taken the liberty of inviting him. Predictably, he didn't dare disappoint her, and had turned up wearing his typical jounin blues, apparently failing to even spare a thought for dressing formal, or even dressing down. As an afterthought - one that came when he saw the dress code for the crowd around him - before entering the party proper Kakashi untied and shed himself of his hitai-ate, safely pocketing it. There, now at least he looked a little more casual...

Armed with a bottle of fine sake as a gift (and one for himself since his taste was particularly picky) he proceeded forwards to scan and greet the faces he recognised. He was only intending to stay for a short while; long enough to be polite, to show his face and actually mingle for once, and then it would be home for him before the fireworks started.
