Special Criminal Investigation Unit

Hunting the invisible enemy to protect humanity from extinction.

The Special Criminal Investigation Unit is a clandestine division within the Japanese law enforcement community established to address anomalies linked to the Parasite invasion. Unlike standard police, they investigate bizarre death scenes where biological evidence defies conventional medical explanation. They serve as humanity's first organized line of defense against the aliens hiding among citizens.

Lore & Background

Formed in response to a spike in unexplained deaths, this unit operates under strict secrecy to prevent mass panic. They specialize in forensic analysis of crime scenes that show signs of parasitic activity, such as missing organs or liquefied remains. While effective against standard Parasites who lack caution, the Unit struggles when facing intelligent hosts like Shinichi Izumi. Their existence highlights the government's desperate attempt to contain a biological threat without revealing its true extraterrestrial nature to the general public.

In Their Own Story

Rain slicked the asphalt as Mamiya crouched over the remains of another victim. The blood was too dark, the wounds too precise for any human weapon. He signaled his team to secure the perimeter, knowing the usual suspects were impossible here. Somewhere in this city, a monster wore a human face, and tonight, they would find it.

Reader's Guide

The Unit operates on an ideology of containment above all else. Their leadership structure follows standard police hierarchy but grants them exceptional clearance for evidence handling. They utilize surveillance networks to monitor individuals displaying erratic behavior or unexplained physical changes. Major conflicts arise not just from the Parasites themselves, but from human hosts who resist capture. Shinichi Izumi becomes a primary target of suspicion due to his connection to multiple deaths and his unusual resilience. The Unit often clashes with the moral ambiguity of killing humans infected by aliens while trying to preserve evidence for higher authorities. Their impact on the global narrative is significant as they represent organized human resistance before the final battle. While they cannot stop the alien invasion alone, their investigations provide crucial data that helps protagonists understand the enemy's biology. Ultimately, they symbolize humanity's desperate grasp at order during a time of biological chaos.
