In the year 5990 of the Galactic Calendar, the Human Interstellar Alliance faced an assault from an alien race known as the Bugs. To resist the impending doom of humanity, the Alliance government developed a humanoid superweapon called the "Puppet." The young people tasked with wielding this weapon in battle were dubbed "Puppeteers." This was the first time Lyle had seen a "Puppet." It possessed neither three heads nor six arms, nor a green face with fangs. It appeared to be an utterly ordinary human being. Except he was strikingly beautiful: long black hair cascading over his shoulders, eyes like pools of blood, pale yet flawless skin, perfectly proportioned features and elegant contours. And around his neck, like an identity badge, was a tattoo bearing a string of enigmatic numbers-SSS-001.
