Back Story (top)*WARNING! CONTAINS SPOILERS*
Hearing that Kasumi had run away from her village to seek vengeance for Hayate, Ryu tracked her to the Dead or Alive Tournament, where he joined the tournament as a participant in order to keep an eye on her. When Raidou and Kasumi had a Ninpo energy duel using the Torn Sky Blast, Ryu threw a kunai into the genetically altered rogue ninja's arm, distracting him long enough for Kasumi to kill him with the Ninpo. But as soon as the dust cleared from the following explosion, Ryu discovers that Kasumi had been captured and leaves to find her.
Ryu entered the second Dead or Alive tournament in order to confront and defeat the renegade Tengu Gohyakumine Bankotsubo, who had somehow managed to escape into the Human Dimension from the Tengu World. After getting close to DOATEC scientist Lisa and taking her ID card, Ryu meets with Irene and infiltrates the DOATEC Germany lab in the Black Forest of Germany. There he finds Kasumi and rescues her from Lisa and Kasumi's clone Alpha.
Thanks to the data he retrieved from the lab, he and Irene piece together the connection between Raidou's inhuman strength and Alpha. To both of their surprise, the Epsilon Project resurrected Hayate from his comatose state. Kasumi tries to go after Hayate despite Ryu's stand against it and Ryu is left with no choice but to send Ayane after her.
Meanwhile, Ryu tries to warn the other competitors about the danger of DOATEC but finds them unwilling to backdown so he proceeds to knock them out of the contest. Eventually he meets Ein, who is actually the missing Hayate suffering from amnesia. After Ryu defeats him and restores some sembolance of his memory, Ryu sets off to face the Tengu of Destruction himself before he could cause anymore damage. Ryu bests the mad Tengu in hand to hand combat, killing him and preventing his madness from spreading.
Ryu reunites with Hayate and Kasumi and, with encouragement, the two battle as siblings, reviving Hayate's memory in the process. But all was not well yet, as their reunion was interrupted by Genra of the Hajin Mon sect. Genra reveals himself as the one who broke the barrier and summoned Bankotsubo and then sicks Ayane, possesed by Genra's Genjutsu to fight the two shinobi masters. Alpha joins the fight but the two emerge the victors. Ryu then introduces Hayate to Irene and fills his best friend in on the DOATEC issue.
Ryu sits on the roof of Azuchi on a moonlit night. He says that Hayate couldn't possibly defeat Genra but Hayate tells him he doesn't know Genra at all. Ryu tests Hayate to see if he remembers everything. Hayate appears to beat him, only to realize Ryu used the Kawarimi (変わり身substitution) technique to trick him at the last second. Ryu tells him that he and Hayate can settle their bout in the third tournament.
Later Hayate and Ryu restart their fight. Ryu initially plays around with Hayate and then he fights him seriously. Things heat up extremely when the two use their strongest Ninpo techniques but the fight is interupted by Ayane, who alerts Ryu to Irene's kidnapping by Christie. After defeating the assassin, Ryu realizes that it was a diversion and rushes to Hellfire to save his friends. As Genra, in his monstrous Omega form, prepares to deal the fatal blow to Hayate and Ayane, Ryu throws a kunai into his helmet and slashes him with the sacred Hayabusa ninja clan relic the Dragon Sword. Using all the strength he can, he buys time for the two Tenjin Ninja to use a dual Ninpo to end the fight, killing Genra in the process as Ryu rolls to safety.
Invited to participate in a group offensive, Ryu joins Hayate, Kasumi, and Ayane to stop DOATEC during the fourth tournament. Ryu and Ayane come across Christie, who was trying to stop the ninjas from destroying the DOATEC Tritower. However, her attempt failed and the building fell from the detonator Helena set off. Ryu also saved Kasumi from being shot by Helena Douglas and later encouraged her to fight her clone Alpha-152, which he thought was her fight alone.

Ryu and Hayate are good friends. They are both the same rank and intelligence and are as close as brothers. Ryu is very protective of his friends so he watches over Hayate, too. In Dead or Alive 3, Ryu decides to destroy Genra to keep Hayate safe. At Hayate's request, Ryu watches over his younger sister Kasumi, hence why he is always by her side.
Ryu and Ayane have worked together on two separate occasions, five if counting the Tengu affair in the second Dead or Alive tournament, the Omega affair, and the Mugen Tenshin Ninja Clan’s attack on DOATEC. Since the Dark Dragon Blade incident, the two seemed to have formed a friendly working relationship, with each recognizing the other’s skills and capabilities.
As a family friend, Ryu is a good friend to Kasumi as he watches over her and tries to protect her from harm during Hayate’s recovery/absence. Her strong-willed nature does prove to make this difficult at times, however, such as when she entered the Dead or Alive tournament, forcing Ryu to also enter if he was to continue keeping an eye on her. He tries to stop her in Dead or Alive and Dead or Alive 2 but fails. He doesn't see her in Dead or Alive 3 but in Dead or Alive 4, Ryu saved her from Helena.
Though Ryu has befriended several people from the Dead or Alive tournaments, Jann Lee is notable since the Tengu incident onwards due to their gradual recognition and respect for each other’s abilities despite Jann Lee being a civilian. They have formed something of a friendly rivalry.
