Brave Series Wiki

Commissioner Juuzo Saejima is a character that appears in the Brave Police J-Decker series


Comissioner Saejima originally conceived and was in charge of the Brave Police Project. He worked closely with his good friend, Chief Engineer Toudou, in order to construct the first robot, Deckerd. After Deckerd was revealed to be self-aware and friends with Yuuta, Saejima changed the rules in order to have Yuuta inducted into the police force as an Inspector despite his young age. He oversaw the Brave Police Division, and issued orders to them. He also acted as their liaison to the rest of the police force, often coming up against Vice-Commissioner Azuma, who was the Brave Police program's strongest critic.

He has a flamboyant, over-the-top personality, and has a deep appreciation for things that he considers 'cool', which tends to interfere with his work in minor ways, such as requiring a vocal command be issued to initiate combinations between members of the Brave Police and ordering a tiger head to be put on the chest of the Build Team's combined form.

Saejima is still single at the age of 45 - the only others living in his house are three servant robots, named King Kizer, God Bomber, and Ultra Diver, referring to various robots from prior entries in the Brave Series.



  • Saejima had never married, stated to be due to his personality.
  • He named Build Tiger, Super Build Tiger, J-Decker, and Fire J-Decker.
  • The voice of Saejima, Ryuzaburo Otomo, went on to voice Genocide in Dagwon.
