Don't mind me asking, but why rabbits?

Why do the black wings use rabbits?

Ever since I played through the Evan plot, there were random ninja-rabbits everywhere in blackwing fights.

Did the blackwings conquer korean folk town's moonbunny tribes? It really makes no sense because they're named "blackwings", yet they use minions that don't resemble ravens in any way.

... Can we start calling them Team Rocket now? :f6:

I don't think anyone really knows. Have you done the Verne Mine quests yet? I know some of the NPCs in there mention this. The Black Wings have different races/species within their ranks, although I don't think it's ever explained why.

 Do not read this unless you want to spoil some details regarding the Verne Mine quests

There are two Mu Lung bears practicing their fighting/meditating while acting as security guards in there. I know one of the quests in there has a security guard bunny essentially insult you for being human. They seem to have enslaved cart-riding bears and shoveling raccoons in the mines as well. Then there are the robots/androids, in which I think one of the bunnies has you try to scare one of them in order to figure out if they are capable of some type of emotion.
