Magic Realm Convenience Store Worker

Our protagonist Chan was looking for a part-time job, after his previously joined company went bankrupt. Coincidentally enough, while doing so, he came across a job advertisement, offering an absurdly high salary. Lured by the extremely high salary and hourly wages Chan decided to join the convenience store as a clerk and work there. However, the customers who visited the shop seemed a bit strange. Vampires, kobolds, and even a succubus?? After seeing all that only one thought came to his mind, “Am I the only normal person in this place? Is this really gonna be, okay?”
