I was banished to a remote frontier.

While the other students were in the royal capital, a single boy was blown away to a place surrounded by high cliffs—Katotou Seiji. His job was the unfortunate samurai class ＜Samurai＞ that couldn't learn any skills, and the ＜High-Rank Monster Tamer＞. The only way to leave the cliff is to conquer the dungeon. "Alright, leave it to me. I've always been good at this." An adventure begins between one boy and magical monsters. Please note that the text at the beginning of the story has less content and is rough in quality.
