Pretty much all I know about Wolfwood is that he's a priest and uses that huge-arse cross weapon, but he and Hijikata can be smoking buddies! They only just ran into each other, but if you have the capacities we can also toss them together at the event.

I can't decide between masquerade shenanigans, wake-up kiss (mutually awkward to the max, no doubt), or a run-in at the manor... I plan to make an event post, so maybe you can just see if anything appeals to you.
