You can move while doing certain gestures- including change facing. Spin around while doing the point up gesture some time.

The first phantom I saw do this was named... Hakurichi, I think? I had been having a series of frustrating fights against the Abyss Watchers, and it made me laugh hard, clear my head, and beat the hell out of them immediately after.

Do a pointspin next time you get summoned and brighten up someone's day!
