Yorinobu Arasaka

The day after 21 year old Yorinobu Arasaka graduated from Todai, Saburo brought him to his private chambers at the compound. There he explained to his youngest son the true nature of the Arasaka Corporation. Rather than agreeing with his father's vision, as Kei had, Yorinobu was secretly appalled. That night, after a celebratory dinner given in his honor, Yorinobu slipped out of the compound and vanished into the Tokyo night.

Now, four years later, Yorinobu has gathered about him a cadre of tough Tokyo nomads: Kotetsu no Ryu...the Steel Dragons. Together, they have sworn to expose and destroy Arasaka. At night they prowl the canyons of the city, harassing Arasaka men and unearthing information on Arasaka black operations. Yorinobu's knowledge of Arasaka facilities and corporate procedures gives the Steel Dragons some advantages, but they still lack the power or information to make serious headway against the corporation. Yorinobu is, however, able to tread the world of the street and the corporate tower with equal facility. When he is not riding with his men, he is travelling the world, meeting with other enemies of Arasaka, looking for funds and equipment. Slowly but surely his operation is growing.

Saburo is greatly saddened by his youngest son's disloyalty and acknowledges that Yorinobu must be destroyed. Kei, who hates Yorinobu for his defection, has sworn to kill his half-brother. Hanako, on the other hand, still loves her brother. Yorinobu was Saburo's only other child by Michiko, and he has always felt a special bond with his sister. Although Hanako is unaware of it, he has sworn to free her from her father's clutches. Once a month Yorinobu and Hanako secretly communicate through the net, reaffirming their fraternal love for one another.
