Bandou Chataro woke up on a rough stone floor. Looking around, he saw his classmates lying in a similar fashion. What caught his eye were the white people in armor surrounding them. It didn’t seem like cosplay. “Everyone! Wake up!” A young woman stepped forward from the crowd and raised her voice. The class representative, who had just awakened, asked, “Where is this?” “This is the Kingdom of Gadol. I am Princess Emilia, the first princess!” It was a country he had never heard of before. His classmates were in a commotion about being transported to another world. Emilia said, “Please save this world, Hero!” His classmates confirmed the title of Hero in their status and got excited, but Bandou watched with cold eyes. Bandou Chataro, the man who had been expelled by the princess, used his unique skill [Hole] to begin the invasion of this other world.
