Type-Moon: Starting with Four Battles, but Transforming into a Spirit

[Fate series][Date A Live][Gender Bender][with a small amount of To Aru Majutsu no Index and Digimon elements]

No one expected that the Fourth Holy Grail War would be suddenly crashed by a bug-level existence.

Mayuri, a spirit, wielding angelic authority. (Later she will also transform into other spirits.)

She doesn't understand magus rules, doesn't understand a king's pride, and her fighting style is simple and direct.

Can't win? Unleash a big move.

Stalemate? Unleash another big move.

The King of Conquerors' army is chased all over the place by lightning.

The King of Knights has no choice but to keep widening the distance to avoid space quakes.

The various Masters stay up all night revising their battle plans.

What was originally a serious and cruel Holy Grail War is forcibly played out into a completely different script by this outsider.
