The MC, Yuji, who works for a black company, was stressed out due to overwork and a failed relationship. As he took the last train home, he fell asleep, woke up, and somehow found himself at an unknown place, Kamifushi-cho. It was a strange place where humans, demi-humans, and monsters co-existed in harmony. Over there, Yuji was able to relax and enjoy a life he hadn't been afforded before.
