The wolves could mean Koryos which were bands of young men who loved to adventure and fight, so bands were made where they were outside society just being marauders. Ireland had the Fianna which had young aristocrats form warbands where they fight each other, and fight for the sake of Ireland. Fianna in Irish myth became legend and associated with lots of magical stuff.
Herodotus thought that the reports of the Neuri transforming into wolves were bullshit by the way.
And he was right, they were almost certainly just festivals where people dressed up as and acted like wolves.
I'd forgotten how good these Munakata stories were, and while I'm glad the folklore and people plots are sharing the spotlight... excuse me while I wipe away this strange liquid my eyes are producing 😢
