Beautiful Enemy - S2.E2

Jiro and Ichiro are having a argument because Ichiro feels that Jiro shouldn't trust Reiko and Akida. He says that little is known about them and they might turn out to be spies or something. Jiro disagrees and says that he trusts Reiko, making Ichiro walk away from them.

Ichiro then encounters a girl android named Beijinder and a fight between them breaks out. Jiro shows up and tries to help but his attempts were basically futile. When Beijinder was about to finish Jiro, Reiko shows up and tells Jiro to look out behind him. Jiro turns around punches Beijinder square in the face. Beijinder is so pissed off at Reiko and charges at her but couldn't attack. Something in her was holding her back. Beijinder then leaves.

Later that night, four Hakaiders shows up and one of them happens to be Gill. Gill explains that when Jiro destroyed the DARK hideout, almost all his men died. He then transfered his brain into a Hakaider's body so that he could live forever. He then goes on to explain that the three other Hakaiders contains the brains of his most trustworthy men.

Gill then demands that he wants his son, Akida, back. The four Hakaiders transform into one huge Hakaider and in order to defeat it, Jiro and Ichiro has to team up. Together, the two brothers defeat the Hakaiders.

As Jiro and Ichiro watch the explosion, Ichiro asks Jiro if he really trusts Reiko. Jiro says yes and Ichiro tells him that he trusts them too because he trusts Jiro.
