The Supreme Ninja Overlord Genshin (邪忍王 玄心 Janinou Genshin; Evil Ninja Ruler Genshin) is the iron-willed Master Ninja of the Black Spider Ninja Clan. He is Ryu Hayabusa's main rival in Ninja Gaiden II and its derivatives, where they fight multiple times.


Genshin is a tall middle age man with medium build. He has an eyepatch covering his injured right eye. His outfit is a mix of traditional gi and armor, consisting of heavy tabi boots, ninja pants, fully armored upper body, armored gauntlets, ninja claw on the right arm, and a multi eyed shinobi helmet.


As Overlord of the Black Spider Clan, Genshin is the most powerful and ruthless Ninja that the clan has ever produced. Genshin's cold and calculating composure, as well as his lust for power is matched only by his hatred of the Dragon Lineage.

Despite the many atrocities he and his clan commit, Genshin is revealed to be an honorable shinobi, as everything he did, from joining the Fiends to becoming a demon himself in hopes of ending the Dragon Bloodline, he did solely for his clan's future; a sentiment his rival Ryu Hayabusa easily related to him with.


Hoping to gain an upper hand in the struggle for ninja superiority, Genshin enters into an uneasy alliance with the Fiends. He will stop at nothing to destroy Ryu and put an end to their clans' centuries-old feud once and for all. Genshin's weapon is The Blade of the Archfiend.


Ninja Gaiden Sigma 2Edit

Genshin, Master Ninja of the Black Spider Clan has grown weary of his clan playing second fiddle to the Hayabusa Ninja Clan, his hatred for the Dragon Lineage now reaching its peak. One day, he meets the mysteriously beautiful yet demonic Elizebet; Queen of the Greater Fiends, who promises to help him bring his clan to greatness in return for his services. Genshin hesitantly accepted, seeing this as an opportunity to destroy the Dragon Ninja once and for all. He sends his student and Black Spider Middle Ninja, Shadow Ninja Rasetsu of the Dark Sect to Tokyo to distract Ryu Hayabusa, while he and an army of Black Spider Ninja attack the Castle of the Dragon. He duels Ryu's father Joe Hayabusa in the castle keep, and steals the Demon Statue, the artefact that the Hayabusa clan has guarded for millennia. Ryu bursts through the door to see his father fall through the floor. As Genshin gives Elizebet the Demon Statue, he duels Ryu and nearly kills him when Joe interferes. He fights Joe and leaves him in critical condition. Meanwhile, on the way to deliver the Statue to the Infernal High Priest in his sky fortress, the Daedalus, Genshin encounters Ryu and fights him again. In South America he tells Ryu that the Archfiend shall resurrect himself in Japan, under the sacred peak of Mt. Fuji, and that there is where Ryu will die. He fights Ryu at the top of the erupting summit and is killed. Elizebet appears and transforms the Ninja Overlord into a Greater Fiend.

Fiend genshin

Genshin, transformed into a Fiend fighting Ryu Hayabusa.

With this newly obtained, incredible power, Genshin follows Ryu into the depths of the Netherworld and challenges him again. Despite the demonic power that Elizebet had given him, Genshin is defeated by the Dragon Ninja, his cursed body slain by the awakened Dragon Sword. With his dying breath, he tells Ryu that he had no regrets for what he's done, just as Ryu fought to uphold the Dragon Ninja legacy of justice, Genshin fought for the future of his clan. Acknowledging Ryu as a true Ninja, he gives him the Blade of the Archfiend and dies, his soul redeemed.

Elizebet chastises the dead Ninja for losing for the sake of his clan's honor. Enraged by this disrespect towards the Ninja Overlord, Ryu kills her with the Dragon Sword and the Blade of the Archfiend. The Blade of the Archfiend now serves as a gravestone to Genshin in the Black Spider Ninja Graveyard at the summit of Mt. Fuji.

Ninja Gaiden 3: Razor's EdgeEdit

Genshin makes a small appearance in Ninja Gaiden 3. After Canna transforms into the Goddess, the spirit of Black Spider Ninja leader appears before Ryu, giving the Dragon Ninja the soul of the Archfiend in order to awaken the Blade of the Archfiend to use to battle the Goddess.
