Lv2 Kara Cheat datta Moto Yuusha Kouho no Mattari Isekai Life

A merchant named Banaza is called to a different world to serve as a potential hero against a demonic force. After it is determined he lacks extraordinary abilities, he is rejected and sent away, but an error prevents his return. Stranded, he must now try to live in this unfamiliar kingdom. It is possible, however, that Banaza's true strength is greater than he or others have recognized.
