Pioneer Sword

Will traveled through time, but something went wrong while traveling. After being in a "little dark room" for hundreds of years, a door suddenly appeared in the room. Will opened the door without hesitation, and then... He succeeded, not only gained a new body but also gained freedom, but he did not expect that he would be built into a statue, and would have to face four beautiful girls who were already frightened. And a world that is about to usher in a century of change.
