He's still got it in his head that most days of the year should be devoted to working hard for the sake of someone - yourself or others, and in this case his god as a shinki - but today is one of those rare days where if he was going to do anything frivolous... he'd certainly allow it of himself and others. This is a kind of festival, after all. A special day where dancing can be part of showing you're happy for the guests of honor.
