Ninja Kamui

After his family was brutally attacked by a gang of masked assailants, Joe Logan is approached by FBI agents Mike and Emma to help investigate the murder of his wife and son.

Higan learns that a string of recent murder victims were all former ninjas who had their covers blown. Higan goes after the boss ninja and swears to take revenge for his dead wife and son by crushing the organization.

Yamaji addresses questions from one of his lieutenants regarding Higan’s survival. Meanwhile, Mike joins forces with Higan and Emma to launch their own independent investigation into AUZA.

A mysterious benefactor warns Higan that it’s impossible for him to infiltrate AUZA City without any help. Meanwhile, Mike and Emma walk away from the accident with light injuries and relaunch their investigation into AUZA and the ninjas.

Continuing his investigation into the ninjas, Mike uses information from Emma to track down Jason, a former AUZA employee. Jason has a vendetta against AUZA and agrees to help Mike by hacking into one of their websites. Among the data they steal, Mike unexpectedly comes across Emma’s name, but AUZA traces the hack and sends mercenaries to shut them down. Elsewhere, after having his first attempt to infiltrate AUZA City stopped by Zai, Higan learns of an alternate route from the mysterious benefactor. Higan chooses to take it, despite knowing that it’s a trap, and gets confronted by the ninja organization’s lieutenants. The lieutenants are equipped with high-tech battles suits called “Gusoku Gear” that give them immense power. The situation looks dire as Higan gets overwhelmed, but before Zai can deliver the final blow, one lieutenant named Aska does something that surprises everyone.

Aska rescues Higan from certain doom and treats his wounds. It turns out that Aska is Emma, a ninja who not only had been sent to infiltrate the ranks of the FBI, but also was the mysterious benefactor that helped Higan. Now that her betrayal of the organization is known, she rushes to prepare a Gusoku Gear for Higan as it’s their only hope of fighting back against the ninjas. Aska explains that she had a special relationship with Higan’s wife, Mari, and actually tried to help her on the day she died. However, she was only able to save Higan. Meanwhile, Jason saves Mike’s life and takes him to a doctor. Mike then learns that he is now wanted by his own agency, the FBI. The ninja lieutenant named Lil finds Aska and Higan’s hiding place and attacks them, forcing Aska to fight back. She desperately tries to stall for time until Higan’s Gusoku Gear is ready.
