30 - 12: The Great Detective Has Arrived

Following the attempt on Owada's life, the police and A.I.M.S. launch an investigation into Hiden Intelligence after Yua reveals Aruto's secret lab to them. When the authorities and Fukuzoe storm the President's office, they are stopped by detective HumaGear and Izu's "brother" Wazu Nazotoku, who tells Aruto that he was brought back online on Korenosuke's orders. Putting his faith in Wazu's plan, Aruto goes on the run to buy his new ally time. Meanwhile, the Assassin HumaGear has grown tired of following Jin's orders and seeks to go his own way following his evolution. Followed by Izu and Isamu, Wazu learns a criminal stole five identical dancer-type HumaGears and changed their faces to become five new identical HumaGears. Four of them were stolen by MetsubouJinrai.net and became the four Assassin HumaGears, but the fifth is missing. Wazu also concludes that the fourth Assassin HumaGear is trying to capture the fifth. When Zero-One confronts him however, he has trouble beating him until Is returns with a newly finished Progrise Key: Shining Hopper.
