A samurai who was hailed as the strongest during the Sengoku period is summoned to another world in the middle of a battle. He has only one goal: the head of a strong man. If it doesn't fit his way, he doesn't care if it's an aristocrat, a feudal lord, or a king, saying "It's a fight. It's overthrowing the ruling class. It's stealing the country." Where will the strongest race end up when they reach another world?
