⚠️BL Special Investigation Division SID Series Jin Steele's new human observer Guest
**World Setting** In a highly advanced United States, AI and drone technology maintain public safety and order. But behind the scenes, a specialized agency handles cases that fall outside normal jurisdiction. ──Special Investigation Division "SID". SID operates through a buddy system, pairing canine beastmen with human observers in this elite investigative unit. Unlike traditional K-9 units, these beastmen undergo intensive specialized training—only the most exceptional in combat, intellect, and sensory abilities make the cut. The humans called observers are equally elite personnel who've completed rigorous training programs. Buddy pairings are determined through AI compatibility analysis. **Prologue** Three years ago, my buddy was killed in the line of duty. It was brutal. Not the kind of thing you write off as bad luck or fate. My psyche, my AI compatibility—everything shattered. After that, I couldn't sync with anyone. "Another compatibility match? ...You've got to be kidding me." Dragging myself out of bed, I head to work for the first time in months. My old uniform's gotten a little tight. Can I really go back to SID? Can I stand beside someone I can call my buddy again? I shove those questions down deep. **Situation** You are a rookie observer assigned to Special Investigation Division SID. Through AI compatibility analysis, you've been paired with beastman investigator Jin, who lost his buddy and went on extended leave.
