Plot Issues #0–6 While training in Japan, Ryu rushes to the dojo after hearing a loud cry and finds his master Gouken murdered. He travels to San Francisco to inform his best friend and training partner, Ken, about their master's death and deduces that Gouken was murdered by his own brother, Akuma. The two decide to go back to Japan to avenge their master's death and are accompanied by Ken's fiancée, Eliza.

Meanwhile, Guile is investigating Shadaloo after the disappearance of his friend and mentor, Charlie Nash. Officer Gibson informs Guile that the organization is keeping several tabs on Ryu after he defeated Sagat in the last Street Fighter tournament. He later meets Interpol agent Chun-Li, who is also investigating Shadaloo after the criminal organization kidnapped her father. Believing that Ryu could be a potential lead towards Shadaloo's leader, M. Bison, the two fly to Japan to find him.

After getting intel of Ryu's whereabouts from Killer Bee, M. Bison sends Vega to Japan. While searching through Tokyo, Vega easily defeats and humiliates the sumo wrestler E. Honda in front of his fans, including Sakura Kasugano, who also sets her sights on locating Ryu after learning about his accomplishments. Vega then bumps into Ken and Eliza and places a tracking device on Eliza's scarf. He attacks the couple in their hotel room, but Ken overpowers him and forces him to retreat. Ken takes Eliza to the hospital, where she encourages him to find Ryu and warn him about Shadaloo.

Near Gouken's dojo, Chun-Li and Guile are attacked by Charlie, who was brainwashed by Shadaloo to become their assassin known as “Agent Shadow.” Guile stops the fight by giving Charlie his dog tags, which helps restore his memory and prompts him to retreat. They later recover at the same hospital Eliza is at, where she criticizes Guile for abandoning her sister Julia and informs them about her encounter with Vega. As Ken finds Ryu in Gouken's dojo, Guile calls him and they decide to meet at the Miyazaki Shrine. Sakura overhears their conversation as she was at the hospital to get treatment for Dan Hibiki, a dojo owner she defeated during her search for Ryu.

Before leaving the dojo, Ryu has a run-in with Sagat, who warns him that Bison plans to brainwash him and use his power for evil. On the way to the shrine, Guile and Chun-Li reunite with Charlie, who has recovered from Bison's brainwashing. He informs them that Bison can control others with his Psycho Power and that Chun-Li's father was murdered by Bison's “Doll Agents” led by Killer Bee. When they are suddenly attacked by Bison piloting a helicopter, Charlie sacrifices himself to send both him and Bison off the cliff to their supposed deaths.

At the shrine, Ryu senses Akuma's presence and challenges him. Akuma easily defeats Ken and later Sakura when she attempts to prove herself to Ryu. After witnessing Ryu show signs of the Dark Hado, Akuma tells Ryu to face him at the next Street Fighter tournament before knocking the young fighter out. Ryu realizes he needs to travel the world and improve his technique if he wants any chance of defeating Akuma. Ken initially agrees to go with him, but later decides to go back to America after learning that Eliza is pregnant. Sakura volunteers to become Ryu's new travel partner so he can train her to become a better fighter.

Though the rest of her team has no luck interrogating the Shadaloo assassin, Cammy succeeds by pretending to be her former self. She learns about her past and Shadaloo's plans to use Psycho Power to restore Bison's body and render all conventional weapons of war obsolete.

After returning from her sabbatical, Chun-Li is assigned to investigate Shadaloo triad gangs that are involved in the film industry led by Dolls Xiayu and Jianyu.

The three manage to track down and defeat Xiayu and Jianyu, but the two Dolls escape after Gen coughs blood and tells Chun-Li he's dying of leukemia.

At the hideout, Interpol finds out that Bison's Psycho Drive is being developed in Brazil, so they send Chun-Li there to work the case with Delta Red. Upon arriving, she attacks Cammy after recognizing the operative as the assassin who murdered her father, but realizes she's not the same person she was before. Shadaloo's head scientist has the Dolls kidnap Cammy to reprogram her, but she is rescued by Delta Red. The scientist and the Dolls escape with the last parts of the Psycho Drive after forcing them to battle one of their brainwashed prisoners, Blanka. However, Blanka ceases attacking after recognizing Cammy since she tortured him as Killer Bee.

Ryu and Sakura travel to Thailand to find Sagat. They are confronted by Sagat's former student, Adon, who challenges Ryu to a fight and loses. He informs them how much Sagat's changed ever since losing to Ryu and that he's gone to India to seek guidance from Dhalsim. Ryu is then invited to come to Las Vegas so he can be included in Ken and Eliza's wedding pictures. On the way to the airport, he teaches Sakura how to perform the Hadouken.

Dhalsim informs him that Gen has defeated Akuma in the past, prompting Ryu to travel to Hong Kong to meet him.

As Ryu leaves feeling conflicted, Gen has his long-awaited rematch with Akuma and dies shortly afterward.

Cammy takes a leave of absence from Delta Red to investigate Bison's Dolls and her past with Chun-Li. They find that two of the Dolls were part of the Thunder Foot Tribe and travel to Mexico to discuss the case with one of the tribe's representatives, T. Hawk. He informs them that the two women were abducted days before a chemical plant forced his tribe to evacuate their ancestral land. Before they can investigate, Chun-Li returns to Hong Kong after learning of Gen's death.

Guile receives a tip from Officer Gibson that the plant is a front for Shadaloo, but later discovers that she was actually a Doll disguised as Gibson to lead Cammy and T. Hawk into an ambush from the Dolls and Bison. They are assisted by Rose, who reveals that she possesses the good part of Bison's soul after he emptied it from his body to master Psycho Power and that Cammy is a clone of Bison that he could use to transfer his consciousness. Bison destroys Rose's body and blackmails Cammy into coming with him after revealing he's holding Delta Red hostage. He then sends out invitations to fighters all around the world to take part in the next Street Fighter tournament, which he plans to use to select candidates for his army.Street Fighter II #0-6
