Now to your next question. Dragons do indeed have hard scales, but they're not as hard as the scales of dragons in popular fiction. They could deflect a blow or two from a human, but any shinigami of sufficient strength, and all Hollows would indeed be capable of wounding a dragon if their attacks connected.

However, dragons rely more on their magical Powers to protect themselves than their scales, and as such their bodies are protected by several layers of powerful arcane wards meant to negate any injury. A dragon that's wounded could also heal itself using Magic, and when the wards are breached there would only be a brief window to attack before the dragon invariably refreshes the wards.

So Yeah, your witches has their work cut out for them.
