Assassin's Lab B1

Kaiser Crimson, the head of the ambitious and cutthroat Crimson Family, was a thoroughly ruthless killer. He kidnapped countless civilians and used them for his experiments to create the perfect bio-engineered weapon. When his vicious experiments finally escaped his secret lab, the mutants spread far and wide, killing everyone in the manor. It is said that Kaiser himself was infected by his own freed monsters, turning into the most powerful creature among them.
