Character History

Origin

The boss of the Genm Corp. game Giri Giri Chambara, the character of Kaiden was conceived by Kuroto Dan, the teenage son of Genm CEO Masamune Dan. As a Bugster, Kaiden's origin is traced to the Y2K bug, which left what would be known as the Bugster Virus on the younger Dan's computer shortly following New Year's 2000. Secretly incubating the virus by infecting the young Emu Hojo with it, Kuroto Dan would arrange for its matured form to be extracted by Michihiko Zaizen ten years later, using it to execute the Zero Day incident in the following year.

Initial Emergence

Over five years after Zero Day, the Kaiden Bugster emerged from Detective Heiji Uesugi due to his stress at not being able to solve the case of Zero Day, which had caused the death of his son. Kaiden duels Brave Hunter Quest Gamer Level 5 Full Dragon and Ex-Aid Double Action Gamer Level X in a sword fight, getting weakened by hits Drago Knight and Mighty Double Critical Strikes and retreating back inside of Heiji.

He reemerges when Heiji again feels ashamed of his lack of progress on the case, fighting Brave Level 5 Full Dragon, but this time being defeated by a slash from Drago Knight Critical Strike. His debris are collected by Kuroto with the Gashacon Bugvisor. Chasing the Mystery!

The Bugster Horde

Kaiden was part of an perpetually reviving army of Bugsters which emerged in the real world as a result of Kuroto Dan's plot to revive in the Game World. This endless horde was held off by Kamen Riders Brave and Snipe, sharing the Gashat Gear Dual β and Hunter Gamer between each other, while Emu was sent from CR to the Game World to stop Dan. Maze 2: Escape Ultimately, the Bugster horde was suddenly dissipated in an instant as the destruction of the Game World brought about by Kazuma Kenzaki thwarted Dan's ambition to revive. Maze 3: Gorider Forever

Level 40

"I am Kaiden, of the fortieth standing."
―Kaiden Bugster Level 40[src]

Advancing to Level 40, Kaiden emerged from Neironzu band member Shishido alongside Level 20 Motors and Level 40 Gatton. Engaged by Kamen Rider Ex-Aid Double Action Gamer, supported by Shishi RedIcon-crosswiki, Kaiden and Gatton quickly fled, leaving Motors to be pacified. Confronted by the Kamen Riders at the Seito Stadium, Kaiden was engaged by Kamen Rider Snipe Simulation Gamer Level 50, who destroyed him with the Bang Bang Critical Fire.

Soon after, however, Kaiden was revived among all component Bugsters through the Gashacon Bugvisor by Parado as Kamen Rider Chronicle commenced. Go Together, Embracing Your Ambitions!
