However, in the year 2022, the world has not been destroyed yet, and their master says to the warriors who mastered powerful martial arts but never had a chance to show off their deadly skills, "We're dismissed!" Then, the group of warriors who are completely undemanding and have no social common sense start their life in the big city of Tokyo and come to know pure love, friendship, and conflicts.
