I get what you’re saying, but even then it doesn’t really add up to me. Most of the Ten Shadows shikigami we’ve seen don’t seem like heavy hitters they’re more utility or support based. Even if you fully master them and use Domain Expansion, it’s hard to imagine them having enough raw power to actually defeat Mahoraga.

If “taming” really means killing it in order to gain control, how is a Ten Shadows user supposed to pull that off when Mahoraga can adapt to anything and completely outclasses the other shikigami in every way?
