During the Fourth Holy Grail War, the summoning was tampered with, and someone summoned a... classless elementary school student?
"So you're saying that when you once stood above all ages, you learned a bunch of skills from Gaia? And that this Holy Grail War will be like an old man playing with children?"
The amnesiac Illya, summoned from who knows where, summed up what she had learned while looking at the shadow beside her, whose silhouette was just like her own.
"No doubt about it~ Come on, I'll take you fishing with explosives!"
The shadow replied. For some reason, Illya felt like the black figure beside her, the one who had once stood above all ages, was wearing a mysterious, weird grin.
Blow up the little fish, then blow up the big ones.
Take your time blowing up fish; rush, and you'll just stir up mud.
If you don't blow them up and I don't blow them up, when will the fish ever grow?
I blow up anyone weaker than me, and run from anyone stronger.
Blowing up fish is fun for a while; blowing them up forever is even more fun!
But after a while, why is it getting harder to blow them up?
When the shadow can't blow them up anymore, it conveniently turns invisible, leaving poor Illya to awkwardly smile at the Servants in front of her who aren't afraid of getting blown up.
"So when you said you'd definitely win, you meant any win would count as yours, but any loss would be mine?"
Fourth War -- Prisma Illya -- ?
If you're worried I'll abandon this, read with confidence. I've already finished a million-character novel, and I've never abandoned one before, meow~
