Ookami Kakushi

Regardless, by default gg is never right, so let's proceed with Frostii's version:

Episode 2 - Frostii


I think it's pretty safe to guess at this point that the denizens of the old town are all wolves that avoided extinction by the modern times by assuming a human form. Kushinada is part of some upper echelon whose job is to make sure nobody ever finds out the truth by eliminating all individuals who can't control their bestial impulses well enough or who get too close to normal humans (there are probably lots of them in the new part of the town, moved in from elsewhere). I guess many of the students of that particular school are wolves, and they exhibit the usual pack behavior by flocking around the newcomer Hiroshi. Isuzu must be totally in heat and Hiroshi's smell is enticing her.

That's my theory anyway.
