I think it's going to be fun if anyone tries completely mundane weapons on Saber. Or when she shows off her fighting skills.

... Or when Nonon turns her clothing into a bodysuit equipped with musical cannons.

Also there is no way to wish Kaguya dead, actually! The form of immortality granted to Hourai immortals so so utter and complete that it's less immortality and more being completely removed from mortality. Also Mokou is actually far too into Kaguya to want to really kill her anymore. <.< >.>

... In much the same vein there is a character I have been wanting to use but is not very usable for RP's.
