Summoning a Nightmare

What if Saito was not the one to be summoned, but that from another world from a different version of Earth. Where spirits cause spacequakes, and to pacify them, you have to make them fall in love. Out of all the spirits possible to summon, it has to be Tokisaki Kurumi. Shall the story take a more darker path, or would something else happen? Updated whenever, no scheduling.
