Ryu first appeared in the Ninja Gaiden beat 'em up arcade game in 1988. In that same year, Ninja Gaiden was released on the NES (Famicom, in Japan) and the Sega Master System, though these versions, being 더 많이 centered around platformer-style gameplay, bore little resemblance to the original arcade game. Two NES sequels, Ninja Gaiden II: The Dark Sword of Chaos and Ninja Gaiden III: The Ancient Ship of Doom, followed in 1990 and 1991 to complete the trilogy. Also in 1991, Ninja Gaiden Shadow was released on the Game Boy. Ryu's 다음 few appearances were as a playable fighter in the Dead 또는 Alive series, which saw releases on the PlayStation, Sega Saturn, Dreamcast, PlayStation 2, Xbox and Xbox 360 platforms, as well as in arcades.

There is no story to the original arcade version of Ninja Gaiden, except that Ryu and an unnamed red ninja sidekick (possibly Joe/Jo/Ken Hayabusa 또는 Momiji) who serves as the 초 player were beating up their foes throughout America. Ryu's story commences in Ninja Gaiden for the NES, when he receives a letter from his father, who has departed to fight a life 또는 death duel. Players are left to guess as the story progresses throughout the game, as the young Hayabusa goes on his quest for revenge and to uncover the truth behind his father's disappearance. This was followed 의해 the 다음 two games of the trilogy, which have mysterious introductions that unfolded in a similar manner. In Ninja Gaiden II, players are introduced to a new villain who wields the Dark Sword of Chaos. In Ninja Gaiden III, Ryu Hayabusa is framed for killing his girlfriend.

Eventually, Ryu moved from Ninja Gaiden to Tecmo's Dead 또는 Alive series. Taking place chronologically years after his exploits in the Ninja Gaiden series, he adopts a new, sleeker look. His story is fleshed out more, as a new ninja clan is introduced, several other supporting characters, and a new, serpentine plot that he finds himself intertwined in. He has been a participant in every DOA tournament, canonically winning the 초 tournament 의해 killing Tengu. His cohorts have claimed the other contests.

Finally, after the long wait, Ryu returned to Ninja Gaiden for the Xbox, in a 3D action game with new and original gameplay. The prologue explains the Mythos of the Dragon Lineage who sided with the 용 against the Evil Deities and the Tribes, and how they slew the Dark Dragon. The 용 are described as god-like, benevolent creatures with metallic bones, teeth and claws, created 의해 the Deity of Creation to counter the Evil Deities. The prologue includes a brief history of the two Dragon Swords. The first is the Dark Dragon Blade, carved out of the bone of the legendary Dark Dragon that betrayed his brethren out of jealousy and thirst for power, joining the Evil Deities. This blade consumes evil, charging as 더 많이 evil is committed in its vicinity. As a result, the weapon turns its wielder into the devil incarnate. The 초 sword is the Dragon Sword, carved from the fang of the Dragon, and bequeathed the Dragon Lineage from generation to generation, and finally to Ryu Hayabusa. It is the same sword used 의해 Ryu in the NES Ninja Gaiden trilogy.

The story of Ninja Gaiden (Xbox) deviated from the original NES Ninja Gaiden Trilogy 의해 a few small retroactive continuities. Ninja Gaiden (Xbox) and it's sequels Ninja Gaiden: Dragon Sword and Ninja Gaiden 2 serve as prequels to the NES Ninja Gaiden series, both series are connected to the Dead 또는 Alive series. Timeline wise the events the current Ninja Gaiden series happen first, then the NES Ninja Gaiden series, and finally the Dead 또는 Alive series. [1]

Ryu's name as taken from the video game 거리 Fighter, the reason for this, is because the writer for the Ninja Gaiden series favourite character was Ryu.
