Father Pucci Wants a Peaceful Life

This should count as an infinite-flow novel, I guess. The protagonist's journey roughly goes like this (tentative): Father Pucci hates the Holy Grail War, Father Pucci discovers that the real world is more complicated than it seems, A Certain Scientific Father Pucci, Father Pucci may have summoned a fake Saber (FGO), Father Pucci is from another world???
