The Type-Moon Summoner in the Apocalypse

A young man unexpectedly finds himself in a post-apocalyptic zombie world. Not only does he have no so-called golden finger, the place is utterly desolate, and he has no idea how to survive.

After scraping by for a day or two thanks to the identity of the body's original owner, he is left at his wit's end and sinking into despair. Then a figure dressed in purple suddenly appears before him…

"Oh my, why are you sitting on the ground looking so anxious?"
