Since we're in the questions phase, I'm curious if I'm able to do an idea I gave been kicking around, of a Demi-Servant infused the Saint Graph of Hassan of the Cursed Arm, and a severely downgraded version of Zabaniya that catastrophic damage to the target, but doesn't result in an instant kill, and is actively eating away at her "cursed arm" with each use.

Basically, she'd be a "proof of concept" Mash, since this isn't the same Chaldea, but would likely be following the same, general trend of using Designer Dolls over fallible Masters.

Plus, it assures that I'll never be without a Master or Servant, since I'd be both at once.
