Subaru is at a convenience store but then he's suddenly in another world. The interesting thing is, the person summoning him appears to be himself, dying alongside a girl, of which all we see is her hand. He's suddenly in a large medieval fantasy city that resembles every cliché JRPG or MMO anime. You have elf-people, furry people, lizard-like people, and regular humans, shuffling around and behaving just as you'd expect crowds of people to behave in any large city.
