Ishtar and Parvati are still Pseudo-Servants, the only Demi-Servant so far is Mash.Ok so basically, this is a Shirou being used as a Demi-Servant (like Rin to Ishtar, or Sakura to Pavarti) by Muramasa, the famous blacksmith (and NOT a Pseudo-Servant, like with Waver to ZL...where Waver has primary control)
