Al Jarde, an adult with facial hair and tattoos, is a martial artist entangled with criminal elements. His life is defined by intense personal tragedy: the loss of his family in a terrorist bombing he blames on the wealthy and influential Hayama Gaho. This fuels a profound desire for vengeance, driving him to target Gaho and his associates within the Japanese underworld faction, Jinkokusha, implicated in the attack.

His quest intersects with Minami Uezono of the Counter EX-ARM Squad when he discovers her connection to Jinkokusha during an EX-ARM auction on Megafloat. In the ensuing conflict, he captures Minami's android partner, Alma, and rewrites her AI programming to turn her against her allies. Soma, Minami's brother who seeks retribution after losing his body in a terrorist attack, joins Al Jarde's cause.

Al Jarde's actions escalate as he participates in a hostage situation orchestrated by the primary antagonist, Beta, who manipulates Jinkokusha and others for his own goals. Confronted by Minami Uezono challenging his cycle of violence, Al Jarde experiences a pivotal shift. This leads him to reconsider his path, culminating in a moment of redemption where he sacrifices himself to protect Minami during a critical battle. His death, alongside Soma's later sacrifice, underscores themes of vengeance and its consequences, exemplifying loss and the possibility of redemption amid entrenched hostility.
