Juzo Hasagawa is the no-nonsense leader of the Cyber Police's special operations, which means he's in charge of the explosive collars on Sengoku, Gogul, and Benten. A chain smoker, he always has his lighter handy, which also controls the timer on the collars.

Hasagawa doesn't like hearing 'no' as an answer. Either the criminals do as he orders... or else he blows up their heads. He doesn't enjoy placing the criminals' lives hostage... but he hates crime even less. He also has no patience with any of their outbursts - which includes Sengoku, for which he gives the harshest treatment. But he also can see the hidden good within all of them, and as a reward for a job well done, he takes time off their sentences.
