In 2075, David Martinez is a young man attending the prestigious Arasaka Academy at his mother Gloria's behest, despite their financial struggle. David illegally modifies his visor to avoid paying for a required update to keep attending class. The modifications crash the school's system, and Gloria agrees to pay for the damages. Returning home from meeting with the headmaster, David engages in an argument with his mother, which ends when they are caught in a drive-by shooting between gang member
Doc agrees to install the Sandevistan, which grants David increased reflexes and slowed perception of time for a short period. Using his new abilities, David returns to school and beats up Katsuo. He does so in full view of the security cameras, resulting in his expulsion from the Academy. Katsuo's father, Mr. Tanaka, an Arasaka executive, notices that David can utilize the Sandevistan with no apparent side effects, making him a valuable test subject for Arasaka's latest product. Meanwhile, as D
David is confronted by the gang, led by a man named Maine, who reveals that Gloria had sold the Sandevistan to him a day before her death and that he is one of her acquaintances. David offers to work for Maine, demonstrating his compatibility with the Sandevistan. Intrigued, Maine honors his friendship with Gloria by giving David a chance to prove himself. The next day, David meets up with the gang, and Maine introduces him to the other members: Kiwi, Dorio, and Pilar. David then participates in
As a new recruit, David receives training and instruction from the other gang members, including running errands for Pilar and his sister Rebecca, learning how to drive from Maine, and jogging at night with Lucy. He also participates in several jobs with the crew. He learns that Lucy is a talented netrunner. One night, on the way home from a bar, Pilar begins harassing a homeless man urinating on the street. The homeless man is revealed to have cyberpsychosis and kills Pilar with a previously co
The gang tries to find more leads on Tanaka, and Kiwi mentions she discovered that he secretly indulges in illicit braindances created by "JK." David recognizes the initials as the handle of Jimmy Kurosaki, a famous snuff BD director who also custom-tunes BDs for special clients, including Tanaka, and David explains that Tanaka will have to be present in person for the tuning. Seeing an opportunity to ambush Tanaka, the gang attempts to kidnap JK, but he outwits them, captures David, and flees t
Maine begins developing signs of cyberpsychosis as he starts having trouble controlling his implants, randomly blacks out, hallucinates, and has mood swings, culminating in him losing his self-control and assaulting Kiwi as she tries to hack into Tanaka's cyberware, seriously injuring her. Lucy only agrees to take Kiwi's place provided Maine is kept away and David accompanies her. As Lucy dives into Tanaka's mind, Tanaka regains consciousness and begs David to let him go, saying that he was resp
Months after Tanaka's botched kidnapping, David has become the new leader of Maine's edgerunner group, having taken on more implants—including Maine's arm implants—and becoming a renowned edgerunner himself. However, he has been unable to convince Lucy to rejoin the crew. After completing a job for the fixer Wakako Okada to rescue a VIP from the Maelstrom gang, David is approached by Faraday, who offers him a job from Militech against Arasaka as a test to see if he is worthy of inheriting Maine'
Taking on Faraday's job, David kills an Arasaka lab director. Still, he shows signs of cyberpsychosis—during which he murders an innocent staff member who walked in on him killing the director. Believing Militech to be involved in the mysterious deaths of Arasaka personnel, Arasaka Counterintelligence arranges an assassination attempt on Faraday, who escapes. Due to Faraday's lack of results in recovering data on Arasaka's cyberskeleton project, Militech refuses to protect Faraday any further an
After interrogating Lucy, Faraday and Kiwi discover that Lucy has been actively hiding Tanaka's data on David as a potential test subject for the cyberskeleton and was responsible for Tanaka's death to ensure his silence. Realizing this, Faraday plans to offer Lucy and David up to Arasaka to secure his position in the company. Faraday assigns David a mission to assault an Arasaka convoy to carry this out. Aided by Kiwi, Rebecca, and Falco, David seizes the convoy's main cargo, which is revealed
After receiving military-grade immunosuppressants from Doc, a deteriorating David fights through Militech, Arasaka, and MaxTac forces as he, Rebecca, and Falco head for Arasaka Tower. Meanwhile, Kiwi decides to cut ties with Faraday, who has her killed as a loose end regarding the cyberskeleton. Before dying, Kiwi tips off David and the others on Faraday and Lucy's location. After running out of immunosuppressants, David attacks the tower and kills the Arasaka security to rescue Lucy. Realizing
