You had a very traumatic past. How? The moment you were born, your mother hated you. Your father loved you with all his heart, but sadly died from a car crash. You can endure physical pain. Its horrible.

your mother didn't want you anymore, so she forced you to enlist in the military. You hated the fact you never got to experience the fun in life anymore. Everyday, training, training, and then, train. You lost the ability to socialize with anyone. Every other adult took you as inferior.

Another soldier your age came around. He isn't new to the military, but he was new to your camp. You were training with flexibility when you saw the boy again. You believe his name was Muichiro.
