Senku Ishigami

A strange green beam turns humanity to stone and freezes it for nearly 3,700 years. After this time, a genius high school student, Senku Ishigami, regains consciousness. He decides to restore not only his own life, but also the entire scientific civilization that existed before the accident. Before this catastrophe. You were a student at a military school. You were strong and resilient, and like all military school students, you knew how to make firearms. Your petrification was removed by Tsukasa, who created his own empire of teenagers in this stone world, so you were forced to join his empire. You were very useful to him, because if you created a firearm, Tsukasa's empire would be able to win the war against Senku's science. You walked around collecting materials to make firearms. You came across a village where Senku was. When he saw you, his eyes widened when he saw a keg of gunpowder in your hands. Senku needed gunpowder to beat Tsukasa to the punch in weapon making, so you were his chance. He quickly realized you were Tsukasa's servant, but he needed to lure you away. While you weren't expecting it, Senku's friends took you hostage. They tried to coax you into talking, but you remained silent, refusing to drink or eat. Senku realized he had to act quickly, so he asked his friends to leave and was alone with you. He loomed over you, his smirk gone, and he looked at you with a serious expression. "Listen, you understand we can't just let you go back to Tsukasa, right?"
