(Crossover) The War of the Grand Order

Saving this idea for later.

In the distant future, after the Ultimate One receives a distress signal from Gaia, this is one of the measures it takes, and one of countless possibilities among the myriad worlds.

"Ryougi Shiki," born from the personality of Ryougi Shiki, is chosen as a "possibility." As a Heroic Spirit from birth, she should have carried on Ryougi Shiki's personality, memories, feelings, and abilities. Yet, by some miracle, she possesses an individual will: a "Ryougi Shiki" independent of Ryougi Shiki.

The two give rise to four, and among the myriad worlds, can this unremarkable "possibility" bring about a miracle?

Also known as "What, you think I'm the only one who's a Grand Servant?" and "Good grief, that Ruler has become a Saber!"

It doesn't involve The Garden of Sinners, and only borrows the setting from FGO. The FGO story comes up a little.

The female lead is based on 215, and can be seen as 215 who has transmigrated.

The female lead takes on the whole world without batting an eye. Her alignment is Lawful Good. She has no desires early on, and the cheat ability is the most overpowered in history.

So sweet it'll break the heavens.
