Summary
Kayneth summons a Servant, but she's not the one he was hoping for. Was she, perhaps, the Servant he deserved? The ramifications of this, that flow out like ripples on a pond struck by a rock, will change the face of the 4th Holy Grail War. This is a large crossover, so spoilers for: Persona 4, Fate/Zero, Kara no Kyoukai, Neon Genesis Evangelion, and Tsukihime.
