Protagonist of the series and heir to the Dragon Ninja Clan, Ryu Hayabusa is the eponymous example of a modern day ninja. His black falcon outfit's sleek design is reminiscent to that of the modern special ops agent; still, his tabi boots, ninja head piece, mask, scarf and shin/forearm guards are representative of the ancient ninja warrior. In great contrast to his deadly appearance, beneath the mask lies a handsome man capable of gentle expressions even, while still in his early 20s, Ryu's personality is that of a wise, composed man far older than himself. With this level of maturity, Ryu is perfectly able to act gentle and caring towards his relatives and friends, and very cold and deadly towards his enemies without hatred.

One of the head honchos at the CIA's Secret Auxiliary Unit and Irene Lew's immediate boss, A. Foster is a corrupt CIA agent obsessed with power, demonic power in particular. He attempts to coerce Ryu Hayabusa to fetch the Demon Statues for him in the first NES game. Foster shows his manipulative, ungrateful side when he orders Irene to assassinate Ryu and bring the statues back to him; not getting what he wants and with Ryu still alive, Foster shows up again in the third NES game (second chronologically) The Ancient Ship of Doom
, plotting his "Biohazard" plan. His goal is to create a race of super-beings, and is indirectly responsible for Irene's temporary death, which sets Ryu in full force against him. Unfortunately for Foster, H.P. Clancy double-crosses him at the last moment and he's killed in the end.
- Big Bad: Of The Anicent Ship of Doom at first.
- CIA Evil, FBI Good
- Evilutionary Biologist: Plans to use the dimensional energies to create a race of energy-infused superhuman mutants.
- Frameup: He creates a clone of Ryu and uses it to kill Irene. She survived the assassination attempt.
- Sharp-Dressed Man
- The Unfought: Although some speculate he's the boss of the sixth level in The Ancient Ship of Doom in a mutated form, it's really Ryu's Bio-Noid clone because of the way it refers to Ryu as the original.
Debuting in: Ninja Gaiden II: The Dark Sword of Chaos
The main antagonist of the second NES game The Dark Sword of Chaos
and a warlord, Ashtar is the self-proclaimed "Emperor of Darkness". Said to be both a skilled warrior and a powerful sorcerer, Ashtar is well over six feet tall, and dressed in bulky body armor. With a cape is draped over his shoulders, his face is concealed by his helmet which has three spiky horns protruding from the top and both sides of the head. His mask appears to depict himself crying tears of blood. In parallel with Ryu's Dragon Sword, Ashtar wields the Demon Sword, a blade forged from the bones of a demon.

Foster's accomplice in The Ancient Ship of Doom
, H.P. Clancy helped trigger many of the events during the game. Clancy built the Castle Rock Fortress over the ruins of Jaquio's fallen temple, as he and Foster found a continuous supply of life energy within the ruins; Jaquio's downfall left traces of evil surrounding the site, thus the fortress was built to harvest the energy as a power source, and used it on humans for experiments. He seems remorseful for this, however, as he eventually recruits Ryu to take down Foster. This turns out to be part of his plan all along—he ends up betraying Foster by taking full control of the dimensional warship within the castle ruins, merging with the ancient craft. His ultimate goal turns out to be the destruction of humanity, which he hates for their warlike tendencies.

Heroine of the NES trilogy and Ryu's primary Love Interest
for the whole series, Irene Lew is an agent of the CIA's Secret Auxiliary Unit, working under the codenames "Sea Swallow" and "Sonia"
. Despite her status as an agent, Irene is more of a support for Ryu as she often finds herself captured and winds up being rescued by the Dragon Ninja. When she disregards Foster's orders to kill Ryu after defeating Jaquio, Irene starts to devote her life to Ryu. Sometime after the OVA, she marries Ryu and settles for running an antique shop, while aiding him from time to time during the Dead or Alive

Main antagonist of the first NES game, the sorcerer Guardia de Mieux dubbed himself "Jaquio
" (supposed to be
"Jaki-Oh", as in "Devil King"). While supposedly human, Jaquio appears as a bizarre, uncanny magician with purple skin dressed in a red torn tunic with a hexagram embroidered on the front and a purple skeleton of a demon wrapped in his body like an armor. Jaquio is Chief of the Chaos Tribe, and he plans to steal the Demon Statue and break the seal on the Dark God, plunging the world into darkness.
Debuting in: Ninja Gaiden (NES)
Known as Jô/Joe in Japan and "Ken" in North America for the NES series, he is Ryu's father, current leader of the Dragon Ninja Clan, and previous wielder of the Dragon Sword. Much like his son, Joe is a Master Ninja and in contrast to Ryu who trains for discipline and tradition, Joe seeks to surpass his limits. His preferred ninja attire of choice is a white shinobi shozoku (ninja uniform), although he's adorned with some armor around his body.
In the NES trilogy, Joe leaves Ryu with the Dragon Sword to engage in a duel (later revealed to be one of Jaquio's minions Bloody Malth). The outcome of the fight is not seen, but Joe winds up becoming controlled by Jaquio's magic. Ryu breaks the sorcerer's hold on his father and frees him. In the current series, Joe constantly leaves to continue his training, as Ryu states his father is "never satisfied with the power he wields". In Ninja Gaiden II
, Joe fails to prevent Elizébet, Queen of the Greater Fiends, from taking the statue sealing the Archfiend, as he duels with Genshin, Overlord of the Black Spider Ninja Clan. Injured and blinded, he tasks his son to prevent the Archfiend from resurrecting.
Joe returns in Ninja Gaiden III
, encouraging Ryu to not allow the darkness of his heart, alongside the Grip of Murder, to conquer his very being.
- Back for the Dead: Returns in the end of the first NES game, only to die in his son's arms.
- Big Damn Heroes: A minor one in the final level of Ninja Gaiden III, where he and Momiji save Ryu from a bunch of chimeras he was having a hard time to defeat due to his curse.
- Brainwashed and Crazy: Done to him by Jaquio in the first NES game.
- Doomed by Canon: Unless the modern trilogy doesn't end up negating future events set in stone for the NES trilogy, Joe will die before Dead or Alive.
- Dub Name Change: Ken for the NES series, but the modern trilogy rectifies this back to Joe on both sides of the Pacific.
- Handicapped Badass: In Ninja Gaiden 3, it's implied he was blinded by Genshin in the previous game, due to the blindfold he wears over his eyes at all times, but he's still more than capable of kicking ass.
- Malevolent Masked Man: As the Masked Devil.
- Not Quite Dead: Turns out he survived the duel with Bloody Malth, but winds up getting Brainwashed and Crazy.
- The Obi-Wan: Ryu's mentor until he dies in the first NES game.
- Spell My Name with an "S": Phoenitically, it can be either "Jô" or "Joe".
- Taking the Bullet: Does this for Ryu in the first NES game before he heads to fight Jaquio.
Robert T. Sturgeon
Debuting in: Ninja Gaiden II: The Dark Sword of Chaos
Also known as "Jungle Rat" Robert, he's a United States Army Special Forces operative who aids Ryu throughout The Dark Sword of Chaos
, constantly revealing information about Ashtar. Although no different than a modern day commando, Robert proves himself useful to the Dragon Ninja, including being a reliable informer, following Ryu closely to the Tower of Lahja and surrounding the area with US Army forces to distracts Ashtar from finishing off Ryu. He proceeds to enter the Chaos World for the final battle, but Robert only goes as far against Ashtar, leaving Jaquio for Ryu
. While it seems he dies keeping the demons from reaching Ryu, the OVA reveals he survived, having quit the army and running a private eye agency to keep track of Ryu, but offering him any assistance the ninja might need in the future.
- Armor-Piercing Slap: Robert, a highly trained soldier, after completely raiding a building full of mutants with just his friend Jeff and later all by himself, gets slapped by Katherine shortly after he lives through it.
- Badass: Robert proved himself in The Dark Sword of Chaos from start to finish, aiding Ryu on equal grounds, planning good barricades with the US Army, holding off fiends by himself.
- Badass Normal: And of course, Robert is just a highly trained soldier.
- Blood from the Mouth: After a run-in with the newly-resurrected Jaquio in The Dark Sword of Chaos, a heavily-injured Robert is seen bleeding from the corner of his mouth.
- Blood Knight: While a peaceful guy most of the time, Robert does a long speech in the OVA about how the battlefield for him is not much different than what most men desire.
- The Cameo: Appears in Ninja Gaiden III as the fighter pilot transporting Ryu to rendezvous with Mizuki.
- Cool Shades: Never takes them off.
- Fire-Forged Friends: With Ryu during The Dark Sword of Chaos, later with Jeff in the OVA.
- Mysterious Watcher: Introduces himself as one, and has other minor moments as well.
- One-Man Army: Not to the extent of Ryu, but Robert sure knows his way within the Chaos World.
- Private Detective: After quitting the army
- Retired Badass: Not for a very long time, but still long enough.
- Sunglasses at Night: But Robert is badass enough to make 'em work.
- Wacky Marriage Proposal: After killing dozens of mutants in a closed site with Jeff, adding a high chance of getting himself killed, when Robert lives through it, he proposes to Katherine seconds after in the OVA.

An immigrant from the Dead or Alive
series, Ayane made her way into Ninja Gaiden
in the Xbox revival
of the series. She is from the Hajin Mon sect of the Mugen Tenshin Ninja Clan, which is apparently an ally of the Dragon Ninja Clan. Ayane is the primary choice for the Mugen Tenshin when they need assistance from the Dragon Clan as she has built a mutual friendship with Joe and Ryu Hayabusa. Even though he's leagues above her in rank, Ayane aids him on his missions, either by informing and helping from the sidelines or outright fighting alongside him.
- Action Girl: Gets her chance to shine in Sigma II and Razor's Edge.
- Animal Motifs: Butterflies, from her choice of clothes, to their color and her inconic sash.
- Art Evolution: To coincide with her appearance in Dead or Alive 5, Ayane gets this treatment for Ninja Gaiden III with smaller eyes, more realistic asiatic facial structure and modest measurements. The latter might not be seen as an "evolution", though.
- Attempted Rape: Her first mission in Razor's Edge begins with a terrorist breaking into her massage room while she's dressed with only a towel. He then tries to undo the towel. Take three guesses at what happens next.
- Badass Adorable: She's small, young and cute, but extremely strong.
- Beauty Is Never Tarnished: Played straight in Sigma II, but sharply averted in Razor's Edge. Like Ryu, she is stained by her enemies' blood.
- Canon Immigrant: From the Dead or Alive series.
- Colour-Coded for Your Convenience: Almost everything related to Ayane is purple, including her hair, clothes, aura, ninpo, explosive shurikens, etc.
- Dangerously Short Skirt: The one she wears in Sigma II sure makes it easy to get a Panty Shot.
- Deadpan Snarker: Shows this trait when Ryu is not around, in Sigma 2 and Razor's Edge.
Ayane: No shit.
- Demoted to Extra: Ayane only appears in Ninja Gaiden III to deliver a replacement sword for Ryu after losing the Dragon Sword due to the Grip of Murder. Razor's Edge expands her role though, just as happened between Ninja Gaiden II and Sigma II.
- Easy-Mode Mockery: In Ninja Gaiden Black, dying continuously in the first level results in Ayane giving the player the option to turn the difficulty down to "Ninja Dog". This results in her telling you that you suck for giving up at Normal difficulty; to further the mockery, she gives you ribbons to boost stats for the rest of the playthrough.
- Everything's Better with Spinning: Being based on her fighting style from the Dead or Alive series, her moves revolve around this trope. This girl is totally immune to motion sickness!
- Fan Service Pack: In Ninja Gaiden, she wears pretty concealing clothes compared to her default attire in Dead or Alive; in the sequel, she gets more Stripperific and has noticeably bigger breasts.
- Note a year has passed between the two games, and since she's supposedly in the middle of adolescence…
- Fragile Speedster: The fastest character in Sigma II and Razor's Edge, but isn't as powerful as the other characters.
- Gameplay and Story Segregation: In-universe, Ayane would never dare talk back to Ryu, but not because he's a Master Ninja and she's ranks below him, but because he's one of the few people who don't brand her as a bastard child of the Mugen Tenshin; of course, this won't stop her from mocking him for giving up at the Game Over screen, defaulting to "Ninja Dog" difficulty and presenting him with stat-boosting ribbons.
- When "Ninja Dog" mode is selected, it also changes the default title screen to a picture of Ayane. The implication is that Ryu gets demoted to a true Ninja Dog, thereby making Ayane his superior and consequently becoming the main character. Now she's just insulting a Mook ninja, not the great Ryu Hayabusa.
- Giant Waist Ribbon: Sports one in Sigma II as a Call Back to her Dead or Alive outfits. One of said outfits appears in Razor's Edge as well.
- Highly-Visible Ninja: She certainly isn't dressed for sneaking around in the shadows. Granted, that's not what she does in these games most of the time.
- Jerkass: Averted, as Ayane doesn't show much of her base personality from Dead or Alive in Ninja Gaiden, since she's dealing with mostly higher ranking ninjas like Ryu. Of course, this won't stop her from mocking him at the Game Over screen.
- Jerk with a Heart of Gold: Ayane does treasure what friends she has and is ready to help Ryu and Dragon Ninja Clan whenever possible.
- Kunoichi: Goes without saying.
- Mysterious Watcher: Her appearance in Ninja Gaiden from start to finish.
- Pretty in Mink: Ayane's alternate costume in Sigma II has a white fur neck wrap and gloves trimmed with white fur.
- Scarf of Asskicking: In Razor's Edge, which resemble a couple of butterfly wings in its ends.
- You Gotta Have Purple Hair
- Younger Than They Look: Mind you, Ayane doesn't look her age even in her home series (she's 16 in Dead or Alive). In Ninja Gaiden she's 14 years old, then a year older in Sigma II.

One of the Three Greater Fiends of the Holy Vigoorian Empire, Doku is a fiend incased in a heavy, dark suit of armor, closely resembling an ancient Samurai
. He singlehandly destroyed the Hayabusa Village, killing many of the Dragon Clan Ninjas and stole the Dark Dragon Blade. Doku's goal is to aid his master, the Dark God Vigoor, into converting capable people into fiends and conquering the world. Doku is Ryu's motivation to invade Vigoor, as he also killed his childhood friend Kureha. Although Ryu manages to find and defeat him, Doku's last resort is an attempt to transform the ninja into a fiend, but the transformation is only partial as Doku's disembodied spirit fades away.
Doku returns in Ninja Gaiden: Dragon Sword
as a malevolent spirit haunting the ruins of Tairon.
- Back from the Dead: Although Ryu destroys his initial body, Doku returns in a spirit form for a final showdown. How he manages to show up in Dragon Sword isn't answered.
- BFS: Kitetsu
- Black Knight: Bonus points for Doku as the black armor is his actual body.
- The Dragon: Answers directly to Marbus, who answers to Vigoor.
- The Faceless: Since Doku doesn't have a proper body to begin with, he has no face to portray himself. Instead, he wears a mask as part of his armor.
- Hopeless Boss Fight: It's nigh impossible to defeat him in the first fight in Sigma, unless you're an insanely skilled player. But even if you do, Ryu will die after the fight regardless.
- Lightning Bruiser: While very heavy, Doku's capable of pulling off some fast-paced combos and slashes.
- Obviously Evil: As if his introduction cutscene wasn't enough, Doku reeks of evil from head to toes.
- Recurring Boss: Three times in the same game.
- Spikes of Villainy: Less than normal, but still there.
- Taking You with Me: In his final moments, Doku curses Ryu in an attempt to convert him into a fiend and serve Vigoor.

The man delivering orders to the Vigoorian forces in the first Xbox game, Gamov is a bespectacled, green hat and coat wearing spy, who constantly trails Ryu through the Holy Vigoor Empire, proving himself very agile and quick in the trigger. While facing Rachel, he was supposedly working together with Doku for the Dark God Vigoor, but in reality, Gamov served the Dark Disciple, informing his master on the growing power of the Dark Dragon Blade. When the Dark Disciple was able to get his hands on the weapon, Gamov is the first to fall to the evil blade
.Ninja Gaiden II
reveals more background on Gamov, justifying why he was so agile and can fight Rachel to a stalemate: he was Genshin's younger brother and part of the Black Spider Ninja Clan
- All There in the Manual: That Gamov came from the Black Spider Ninja Clan and was Genshin's younger brother is not mentioned in the main story. You have to find Genshin's diary in Ninja Gaiden II and read the entry about his dead younger brother.
- Badass in a Nice Suit: Gamov certainly doesn't look like he came from a ninja clan, considering the way he dresses and all.
- The Dragon: For the Dark Disciple
- Guns Akimbo, The Gunslinger: Packs two pistols in the fight against Rachel in Sigma, among other things.
- Lennon Specs
- The Mole: Serves the Dark Disciple instead of the Vigoor Empire.
- Considering he was part of the Black Spider Clan, who were seeking the Dark Dragon Blade as well, it's likely he was planning on betraying the Dark Disciple as well.
- Mysterious Watcher: Trails Ryu through the Vigoor Empire
- Off with His Head!, You Have Outlived Your Usefulness: The way the Dark Disciple shows his "gratitude" to Gamov.

The Dragon Shrine Maiden of the Dragon Ninja Clan, sworn to protect the Eye of the Dragon, Momiji's older sister and Ryu's childhood friend, Kureha is part of the Dragon Lineage was destined to play part in keeping the clan's tradition, being inseperable from Ryu since childhood she also wanted to be of importance, while he grew up to be a Master Ninja, she grew up to be a Shrine Maiden. Then as guardian of the Dragon Lineage Shrine, she was charged with the protection of the Eye of the Dragon, Kureha fufilled her task to death as Doku killed her in an attempt to steal the Eye of the Dragon; it was for her that Ryu went on a quest for vengeance towards Doku. Kureha briefly returns as an spirit in Dragon Sword
, aiding Ryu and Momiji against the Dark Dragon.
- Childhood Friends: With Ryu
- Death by Origin Story: Kureha's early death in the game triggers Ryu to a long and vengeful mission.
- Disposable Woman: Originally, Kureha only existed motivate to Ryu with her cruel death, even though she would become relevant in Dragon Sword. One can wonder why she has a voice actor credited in the Xbox game since we never hear a word from her.
- MacGuffin Guardian: In the normal sense, Kureha is just a shrine maiden tasked with protecting the Dragon Clan's treasure Eye of the Dragon.
- Miko: For the Dragon Ninja Clan, as being part of the Dragon Lineage is a requirement to be the village's shrine maiden, Kureha was fated to be one since childhood.
- Non-Dubbed Grunts: In the Japanese track for the first Ninja Gaiden, Kureha has a weak death cry in her final moments, while in English track she hasn't. That's why there's no credited voice actress in the localization. Jun Shikano reprises her role of "grunts" in Dragon Sword, which in fact she is right at home, as the characters in the game are portrayed in The Legend of Zelda grunts-only style.
- The Obi-Wan: To Momiji in Dragon Sword
- Passing the Torch: Kureha, as a spirit, hopes that Momiji will take on her sister's duty as a shrine maiden.
- Posthumous Character: Kureha's background is explored in Dragon Sword.
- We Hardly Knew Ye: Isn't it sad, Kureha?

The Ruler of Hell and one of the Five Greater Fiend Lords of Vigoor in the first Xbox game, Marbus is the Greater Fiend who guards the Holy Vigoor Emperor, the mastermind behind the theft of the Dark Dragon Blade. In contrast to other Greater Fiends, Marbus has legions of lesser fiends as his direct followers, often leaving the dirty work for them only acting himself when he sees fit or worthy. Ryu happened to be one these worthy as Marbus was forced to take him on directly, the result was the Greater Fiend losing and targeting Ryu for his personal revenge in the future. Marbus returns in Sigma II
looking for Ryu to exact his revenge upon him, yet he finds Rachel instead and is defeated once again.
- Art Evolution: Marbus' design changed quite a bit when he came back in Sigma II.
- Ascended Extra: Marbus in Sigma II comes back with a sudden character, he is now full of hatred against Ryu, full of lines and more demonic than ever.
- Cool Chair: Fitting for the Archfiend of Hell.
- The Dragon: To Vigoor
- Dragon with an Agenda: That said, Marbus doesn't seem very concerned about his master being dead when he comes back in Sigma II. In fact, he's less concerned about his realm and more about being defeated by Ryu.
- Flat Character: For someone who is said to be behind everything Doku did, Marbus got much less exposition than his subordinate. Ironically, he gets more exposition in his small role for Sigma II.
- Flunky Boss: The only boss to be this at normal difficulty in the first game. In a twist of this trope, Marbus' flunkies are previous bosses. At higher difficulties, he hides behind Nicchae and Ishtaros, who are actually harder than he is.
- It's All About Me: Marbus in Sigma II seemed more upset about Ryu defeating him than killing his master.
- Meaningful Name: Marbus is named after the same-named President of Hell from The Divine Comedy's Dante's Inferno, where he rules over 36 legions of demons, just as Marbus controls over many fiends for himself.
- Not Quite Dead: Ryu didn't kill Marbus enough; apparently, all the ninja did was scar him and cleave off one of his horns.
- Scars Are Forever: While it didn't look like that in the first game, Ryu cuts off one of Marbus' horns and leaves him with a few scars in Sigma II.
- Slouch of Villainy: Marbus does a good impression while he waits for Ryu to face off against his minions in the first game.

The leader of the Shadow Clan Ninja and Ryu's maternal uncle, Murai is a former member of the Dragon Ninja Clan who went rogue and formed his own ninja clan, while prefering to stay away from the Dragon Clan's affairs. Murai still wanted to keep a good relationship with the Hayabusa Clan, thus aids nephew by opening the Shadow Clan Fortress for Ryu's training routine. Murai is open about his extreme philosophy of the ever-increasing need for power a true ninja must possess, no matter the cost, so he tries to push some of it to Ryu by trying to make him accept the Dark Dragon Blade. As the Dark Disciple, Murai divulged the presence of the Dark Dragon Blade to Vigoor, who ordered Doku to raze the Hayabusa Village and retrieve it. As Ryu's Roaring Rampage of Revenge continued, the dark weapon grew more powerful, giving Murai the chance to take the sword for himself after Vigoor is destroyed. Unfortunately, he did not account for the strength of the True Dragon Sword and is soundly defeated by Ryu
- BFS: The Dark Dragon Blade
- Big Bad: Of the first Xbox game
- I Let You Win
- Evil Makes You Monstrous: With the Dark Dragon Blade in his hands, Murai's body turns demonic.
- Evil Uncle: Whether he was Evil All Along is never known, though the implication of forming your own ninja clan and going rogue is all the more telling that it might be true.
- Fighting with Chucks: Murai's skills with the nunchakus are to be praised, since Ryu's use of the weapon is incomparable to his uncle, both in power and speed.
- Large and in Charge: From what little we get to see about Murai, he appears the tallest and most muscular of the bunch; naturally, he is in charge of his own clan.
- Lightning Bruiser: Faster and more powerful than the mooks; though slower, he's still quite capable of some nasty rushdowns.
- The Man Behind the Man: As the Dark Disciple, Murai was behind everything.
- Manipulative Bastard: Murai let the Dark Dragon Blade switch from hand to hand intentionally to feed its evil, growing power before he got his own hands on it.
- Wake-Up Call Boss: Oh so much. So much that being able to beat him means you are capable of beating the game.

The legendary weapon smith and shop owner who aids Ryu on his journeys, Muramasa is a fairly mysterious merchant who seems to have traveled across the entire earth, with a swath of knowledge regarding relics and antiques alike. Despite his frail, old appearance, Muramasa seems to know a few tricks regarding the sword, as seen in Sigma II
- Adam Smith Hates Your Guts: The price of weapon upgrades increases with the levels, so thousands of yellow essence will be spent upgrading weapons with many levels. In particular, the Wooden Sword will make some players focus solely on it and leaving other weapons behind to reach the maximum level.
- Inverted in Sigma II where weapon upgrades are free (but you can only upgrade one weapon at a time) and bringing him Crystal Skulls gives you a permanent discount. Finding all skulls halves the price of healing items, which is quite helpful at higher difficulties.
- Back Stab: Muramasa sneaks behind one unsuspecting ninja in Sigma II and backstabs him with a mantis sword.
- Badass Grandpa: Muramasa still does some impressive things even in his advanced age, he still shows some skills with swords and can take care of himself pretty well as Ninjas who try to wreck his shop don't succeed in killing him.
- The Blacksmith: Muramasa personally upgrades all of Ryu's weapons if given enough yellow essence.
- Ultimate Blacksmith: That said, only Muramasa can handle all these legendary or downright demoniac weapons that Ryu possesses.
- Canon Immigrant: Muramasa appears in Dead or Alive, the 4th in particular; now owning a small Vegetable Mart, in which Lei-Fang and Hitomi fights over a cabbage. He also appears in the 5th Dead or Alive, having been apparently been helping Kasumi while she was in hiding.
- Cool Old Guy: Muramasa is said to be above 100 years old, and he still is a fairly modern guy, funny even.
- Exposition Fairy: Muramasa often lets out some plot points that Ryu needs to advance in his journey.
- Mr. Exposition: In his introduction scenes Muramasa lets out directions about a place Ryu needs to go or about the situation the Ninja currently finds himself in.
- Non-Dubbed Grunts: Most of Muramasa's average grunts for an elder aren't dubbed, they're straight from the Japanese track, unlike other characters who got their grunts dubbed.
- Retired Badass: Muramasa, the doddering old shopkeeper, makes carving up ninjas look effortless.
- Which makes it quite hilarious when he says just after that that his old legs won't allow him to go at the top of Mount Fuji. This is dubious since he apparently managed to build statues of himself in the Underworld…
- Too Long; Didn't Dub: Muramasa's greetings aren't dubbed in Ninja Gaiden II and Sigma II, he says Irasshai instead of Welcome to Ryu when his shop is accessed, which isn't even long anyway.
- Walking the Earth: Prior to the games, it is said that Muramasa personally erected all of his statues that Ryu eventually finds in his journey, every single one of them.
- Which would include those in the Underworld... that's some prowess indeed.
- Wall of Weapons: In Muramasa's shop.

The main girl for Ninja Gaiden
(Xbox) and fiend hunter from the Holy Vigoor Empire, Rachel is somewhat a tragic heroine. She and her sister Alma were afflicted with a blood curse that turns humans into fiends. By the events of the game Alma has already succunbed into a complete fiend. Rachel still maintains her human form and becomes a fiend hunter; believing that her sister has no more chance to revert back, Rachel sets on a journey to put Alma out of her misery. Rachel gets caught up in Doku's plot to bait Ryu, as the Greater Fiend also has Alma under his control. Rachel pursued him only to get captured herself; Ryu manages to rescue Rachel and in return she saves him in time for the final bout against the Dark Disciple. In the end Rachel seems to have become quite enamored with Ryu but he doesn't reciprocate. She's seen again in Sigma II
during a fiend hunt, Rachel is looking foward to reunite with Ryu again.
- Action Girl: While playable in Sigma, becomes a full-fledged one in Sigma II.
- Animal Motifs: The Snake, her health bar in Sigma is shaped like a snake, and her sorcery in Sigma II is called Ouruborus, the thematic symbol of a snake eating her own tail.
- Big Damn Heroes: Rachel helps Ryu escape the Underworld of what it seemed a certain death for the Ninja.
- Boobs of Steel: Rachel's physical strength is proportional to her voluptuous bust. She can even handle heavy weapons better than Ryu at first in Sigma.
- Canon Immigrant: She finally appears in the Dead or Alive series in the Updated Re-release of Dead or Alive 5.
- Chuck Cunningham Syndrome: Dropped off the face of the Earth in Ninja Gaiden 3. While almost all characters from the series (old trilogy to present generation) get a nod, Rachel ceased to exist.
- Distressed Damsel: After Doku captures her, Rachel spends the rest of the story like this.
- Dogged Nice Girl: In a rare female example, Rachel by the end of the first Xbox game has taken quite a liking to Ryu, but he promptly seems to refuse, and going by the series' continuity Rachel isn't going anywhere with Ryu.
- Drop the Hammer: War Hammer (which looks like an axe instead) in the first game, Inferno Hammer (which looks like a hammer this time around) in Sigma II.
- Faux Action Girl: In the original Xbox game Rachel wasn't playable so in story segments she falls straight into this.
- Gatling Good: Rachel sports a Gatling Gun as her projectile weapon in Sigma II.
- Hammer And Gun: Her movelist has some oddities like the "SSSO" combo, which consists of melee attacks quickly followed by a gun salvo.
- Hopeless Suitor: The Xbox continuity is established as prequels to the NES and then Dead or Alive continuity, by then Ryu is already Happily Married, certainly not with Rachel.
- Hot Witch: Rachel's super art is called sorcery in Sigma II after all.
- Informed Ability: The guidebook states that she has the ability to sense when fiends are nearby, but this does not affect gameplay at all.
- Kill the Ones You Love: Rachel has reached this conclusion with her beloved sister Alma, she doesn't think there is other way to save her sister anymore.
- Mighty Glacier: As strong as she is, she lacks Ryu's speed and agility.
- Power Crystal: Rachel's crystal earrings are magically enhanced.
- Something about a Rose: Rachel's sorcery in Sigma II is rose-themed and petals flown around it.
- Stripperiffic: Rachel's choice of clothes for fiend hunting are unique to say the least.
- Variable Length Grappling Hook: Seriously, how long can the rope of her grappling hook get, and how does she manage to reel it back into that tiny arm device? In the Collapsing Lair she doesn't even seem to be grappled to anything. We don't see the end of the rope, she's just… suspended.
- Waif-Fu: Rachel is very strong despite her slender figure, due her cursed fiend blood she can best enemies many times her size and obviously more muscular than her.

Known to the Empire as the Holy Vigoorian Emperor, this is his human form to his God form, the original Evil Deity who spawned the Fiends. To the commoners of the Holy Vigoorian Empire, Vigoor is worshiped as a Supreme Holy Deity, leader of their Holy Vigoorian Order and the absolute authority in their lives. After his defeat in the first Xbox title, a plan is set into motion in the NDS sequel to ressurect him by the ancient goddesses Ishtaros and Nicchea, using the Dark Dragon statues to do so, but it fails as Ryu manages to destroy the statues and kill Ishtaros, then as last ditch Nicchae uses her sister's remains to ressurect Vigoor, it succeeds only for the Dark Dragon to use Vigoor's energy and ressurect himself.

- Back for the Dead: Comes back in Dragon Sword, only to die shortly after.
- Big Bad: Until Murai/Dark Disciple is revealed to be the true Big Bad of the game.
- Clipped Wing Angel: His decayed Chaos Devil form.
- Expy: of Mundus from Devil May Cry
- Flat Character: The patron saint and deity of Vigoor Empire; doesn't have a single line, passage or mention of his personality, he is just a boss fight that the player must pass through.
- Light Is Not Good: His stone angel form.
- Physical God: Introduced as such, changed later, as he is not the only one.
- Raymanian Limbs
- Retcon: In the first Xbox game Vigoor is also referred as Dark God Vigoor aside from his Holy Vigoor Emperor title, implying that he was the the Archfiend, a Physical God beyond all archfiends, then comes Ninja Gaiden II (Xbox 360) and reffers to him as Supreme Archfiend Vigoor, the same rank as Vazdah, changing Vigoor from the only to one of a possible group.
- Given the Vazdah is essentially his son, however…
- Satan: Only in the first Xbox game and NDS sequel, the Xbox 360 sequel kind of makes a devil. Unless you consider that being born from Vigoor's mind and body makes Vazdah The Antichrist, anyway.
Debuting in Ninja Gaiden: Dragon Sword (NDS)
Debuting in: Ninja Gaiden: Dragon Sword (NDS)
The last Dragon Shrine Maiden, Kureha's younger sister and Ryu's apprentice, Momiji eventually replaces her sister's place as a distinguished Dragon Lineage shrine maiden, during Doku's invasion she was undergoing her ninja training in another village thus Momoji was spared of the same fate as her sister; hearing about Kureha's death, Momiji felt powerless and made a vow to become much stronger in her sister's name and taking on the task of protecting the clan's treasure, the Eye of the Dragon. With Momiji's new resolve Ryu takes her under his direct tutoring, making Momiji his official apprentice. In the clash in the DS game, Momiji is captured by Nicchae, is up to Ryu to rescue her, after the Dark Dragon's defeat Momiji goes back to her training under Ryu's guidance. Momiji is seen again in Sigma II
where she definitely became stronger and more than capable of fighting on her own.
- Action Girl: Gets to be one for a bit in Way of The Kunoichi mode for Dragon Sword, becomes a full-fledged one from Sigma II onwards.
- The Apprentice: Of Hayabusa, specially in Shadow Dragon.
- Asian Rune Chant: Utters one in III in the cutscene preceding the Obaba boss fight to conjure a barrier.
- Badass Preacher: A rare Eastern female example. Mikos don't fight, and much less as freaking ninjas, but Momiji excels in both fronts just the same.
- Back-to-Back Badasses/Student and Master Team: She fight alongside Ryu during an entire chapter in Ninja Gaiden 3, proving that her actions in Sigma 2 weren't a matter of luck.
- Blade on a Stick: Her naginatanote , another weapon common for popular portrayals of shrine maidens.
- Boobs of Steel: While not quite to the extent of Rachel, she is still quite well endowed and kicks a lot of ass.
- Canon Immigrant: Like Rachel, she finally appears in the Dead or Alive series in the Updated Re-release of Dead or Alive 5.
- Cool Big Sis: She's shown as this to the children of the Hayabusa village.
- Double Jump: Probably her most unique skill. She's the only character in the series who can do it, which opens up her fighting possibilities a lot. Due to her being a Technique character in Warriors Orochi 3, she can't do this in that game.
- Faux Action Girl: Despite her best efforts, she gets kidnapped at the beginning of Dragon Sword quite easily. However, it doesn't take long for her to become way stronger and perfectly capable to defend herself by the time of Sigma II.
- Friend to All Children: Case in point in Sigma II; when the Tengu Brothers kidnap ninja-in-training Sanji, she personally pursues them all the way to Tokyo to save him.
- Hair Decorations: Always wears a white hair clip on the right side of her head.
- Kunoichi: Originally she was only a Ninja (or rather Kunoichi) in training, then Kureha dies and Momiji had no other choice but to replace her sister due their Dragon Lineage. Although that doesn't stop her from maintaining her ninja skills almost entirely.
- Jack of All Stats: In Sigma II she is this for the girls, whilst Ayane is fast but weak and Rachel is the opposite, Momiji is balanced between the two.
- Lady of War: Beautiful and feminine, yet strong and deadly.
- Last of Her Kind: After Kureha's death, Momiji is the only person worthy of guarding the Eye of The Dragon; much like her sister Kureha, Momiji descends from the Dragon Lineage.
- MacGuffin Guardian: In the normal sense same as Kureha, Momiji is not only a Ninja but a shrine maiden tasked with protecting the Dragon Clan's treasure Eye of the Dragon.
- The Medic: Sort of. She uses her powers to soothe the pain in Ryu's cursed arm in Ninja Gaiden 3.
- Combat Medic: She does it in middle of the stage, albeit only briefly.
- Miko: Replaced Kureha at being the guardian of the Eye of The Dragon, now Momiji is a Ninja and a Miko.
- My Greatest Failure: Momiji blames herself for Kureha's death to some extent, she was taking her Ninja training in another village at the time while Doku wrecked the Hayabusa Village and killed her sister.
- Rapunzel Hair: Even done up in a ponytail, her hair reaches her waist.
- Side Boob: Her default outfit starting Sigma 2 sports this. Hilariously pointed out in Nowgamer's "top ten side boobs in games" article.
- Someone Has to Do It: Momiji could not refuse being a shrine maiden even if she wanted to, her distinguished lineage gave the final word.
- Throw the Dog a Bone: After some dead older sister and self-depreciating heroine arroy, Momiji gets to impress the clan's Master Ninja Ryu himself to train her personally due her determination in getting stronger for Kureha and to protect the clan's children, the results are shown in Sigma II where Momiji definitely has gotten a lot stronger.
- Tomboyish Ponytail: Pretty necessary considering her Rapunzel Hair would get in the way (Not that that has stopped Rachel and Kasumi, though).
- Took a Level in Badass: Her growth between Dragon Sword and Sigma II was quite impressive. In Ninja Gaiden III, Ryu himself recognizes how strong his pupil has become in his absence.
Debuting in Ninja Gaiden II (Xbox360/PS3/PSVita)
The Ruler of Crimson Blood and Queen of the Greater Fiends, Elizébet is the most active villain during Ninja Gaiden II
for Xbox 360, also one of Vazdah's Four Deadly Greater Fiend Lords, and the blood priestess of the Fiend cult, the Order of the Necromantale. Elizébet was tasked with retrieving an important ancient artifact from the ancestral Hayabusa Village. For this she aproached the Black Spider Ninja Clan to help her with the task. In return Genshin and his followers were rewarded with fiend powers to overthrow the Dragon Ninja Clan. Later Elizébet manages to trigger Ryu's anger by capturing Sonia and spitting on Genshin's pride after she resurrects him as a complete fiend. Out of all Greater Fiends she is likely to be the one who really earned Ryu's hatred by corrupting the Black Spider Ninja Clan.
- Aristocrats Are Evil: One of few Greater Fiends who are actually said to be a noble, and of course Elizébet is one of the most evil among them.
- Barbie Doll Anatomy: When she shows up in one cutscene wearing nothing but blood, Elizabét appears to be missing something...
- Beauty Is Never Tarnished: Her form as a Greater Fiend is nowhere as demonic looking as the other three Vazdah's Deadly Greater Fiend Lords.
- Which leads to incredible Squick since her abdomen shows off her internal organs.
- Beware My Stinger Tail: She will regularly try to stab you with her tail. It's not very difficult to dodge, but you'd better dodge it.
- Blood Bath: Elizébet sure enjoys her job as the blood priestess of the Fiend cult. Of course, consider her name is a a Shout-Out to Elizabeth Bathory.
- Bloody Murder: A very vicious long range attack has her sending multiple blood spears at you, which are not only very damaging but also refill her lifebar as they hit you.
- Fanservice: The cutscene preceding your first boss battle with her in Ninja Gaiden 2.
- Femme Fatale: So much that Elizébet is the only Greater Fiend Lord that bothers assuming a human form. She likes to look that poisonous.
- God Save Us from the Queen!: Queen of the Greater Fiends, not much else to be said.
- Horny Devils: Both Elizébet's human and fiend forms are very sexually suggestive.
- Impossibly-Low Neckline: Justified in that what is holding her breasts sure aren't part of her clothes.
- Informed Ability: The Queen of the Greater Fiends sure doesn't look that royal, both Marbus and the Dark God Vigoor have shown that they hold much more ground and followers than Elizébet did.
- Kick the Dog: Literally kicked Genshin in the head after Ryu vanquished him for good, spitting on the fallen warrior's pride.
- Meaningful Name: Elizébet's personality and her bloody design, akin to Elizabeth Bathory.
- Manipulative Bitch: She sought the Black Spider Ninja Clan to help her steal the Demon Statue from the Dragon Ninja Clan, in return she would give them demonic powers, and she did give them power, but of course Elizébet forgot to tell them she sees them as disposable objects and eventually they would fall.
- One-Winged Angel: The only Vazdah's Deadly Greater Fiend Lord who wasn't already transformed to fight against Ryu.
- The Power of Blood: As the Ruler of Crimson Blood, it's to be expected. She weaponizes it for several of her attacks.
- The Smurfette Principle: The only woman among Vazdah's Four Greater Fiends, and the only relevant female Greater Fiend in the whole series.
- Speak Ill of the Dead: As mentioned under Kick the Dog, she defiles Genshin's body and insults him for losing to Ryu, much to Ryu's outrage.
- Stripperiffic: Averted in her human form until very late in the game, where she strips down for an arcane ritual. In her Fiend form, however, she leaves much more skin exposed...along with her spine and ribs.
The Ruler of Lightning and one of the Greater Fiends, Alexi is an antagonist in Ninja Gaiden II
for Xbox 360. Awoken from his centuries-long slumber by Elizébet via the power of the Demon Statue, Alexei quickly makes a bid to conquer New York City, holding court from atop the Statue of Liberty. Despite his haughty demeanor and belief in human inferiority, he is bested in a duel with Ryu Hayabusa. However, he later shows up in the Realm of the Fiends as the ritual to resurrect the Archfiend reaches its crescendo, having recovered from his wounds and kidapped Sonia, Ryu's CIA partner. The two clash for a second time, and Ryu succeeds in slaying the arrogant demonic noble for good.

The Ruler of Storms and one of the Four Greater Fiends, Volf is a vicious, four-armed werewolf and the leader of the Beast-Men tribe of Fiends. When the Greater Fiends were released, he and his lycanthropic underlings conquered the tranquil and beautiful Aqua Capital. For all of his savagery, Volf is also a proud warrior who seeks a worthy opponent.
- Bad Boss: He kills several of his own werewolf minions in his introductory cutscene out of sheer boredom...
- Blood Knight: He revels in the chance to fight Ryu Hayabusa.
- Flunky Boss: Indirectly. Though he fights Ryu alone, the rest of the Lycanthropes in the audience come bounding into the ring upon their master's death. Volf plays this trope straight when Ryu encounters him in the Fiend Realm, leading a pack of centaur-esque demons into battle.
- Multi-Armed and Dangerous: He boasts four arms, like a werewolf version of Goro.
- Our Werewolves Are Different: More specifically, this one has four arms, tattoos, a long white mane, a huge scythe, and can talk perfectly well.
- Sinister Scythe: He wields a particularly nasty weapon called the Eclipse Scythe, an ancestral weapon handed down from one Beast Lord to the next.
- Victory Is Boring: He and his lycanthropes conquer the Aqua Capital with barely any effort. And he's not happy about that.
- Not-So-Pretty White-Haired Wolf-Man
- Worthy Opponent: He comes to view Ryu as one, and challenges him to a proper duel in the Colosseum.

The Ruler of Flames and one of the Four Greater Fiends, he is perhaps the most demonic of them in appearance, resembling a monstrous devil with pitch-black skin and bat-like wings. He has a low opinion of humanity, considering them little better than primates, and claims to have bestowed fire upon them centuries ago (without which, he insists, they would have been nothing). Upon his release, he lays siege to a Russian-esque city in Northern Europe and eradicates their military, demanding that they submit or die.

Originally a human philosopher in ancient times, Dagra Dai roamed the earth while the Fiends battled for supremacy. Stumbling upon the resting place of the Arch-Fiend Vazdah, Dagra Dai gazed into its eyes and was transformed into a Fiend, himself. From that point onward, he took the title of Infernal High Priest and brought the Four Greater Fiends together under the Arch-Fiend's banner. In the present, Dagra is the second main antagonist of Ninja Gaiden II. having orchestrated the release of the Four Greater Fiends and the ritual that will ensure Vazdah's resurrection.
Debuting in: Ninja Gaiden II (Xbox 360)
The Ninja Overlord, Master Ninja of the Black Spider Ninja Clan and later one of the Five Greater Fiends of Vazdah in the Xbox 360 game, Genshin is the best and most ruthless ninja the Spider Clan has ever created, with eternal lust for power and hatred towards the Dragon Ninja Clan, he didn't think twice when Elizébet offered him more power for his clan and an excuse to anihililate the whole dragon lineage and its followers. Genshin successfuly destroyed great part of the Dragon Ninjas' village up to fighting against Joe Hayabusa, and managed to steal the Demon Statue for Elizébet; Ryu fights against Genshin four times during the story, in the third he kills him, the fourth Genshin is ressurected by Elizébet as a Greater Fiend, but Ryu once again prevails and finished Genshin off once for all, also despite Genshin's hatred for Ryu's clan it seems both of them developed a less harmful rivalry during their fights, it is clear that when Genshin died most of his hatred was gone as well, Ryu was really infuriated when Elizébet spit on Genshin's pride.
- Above Good and Evil: Joe Hayabusa accuses Genshin's clan to be corrupted by evil, Genshin remarks that the ninja way knows neither good nor evil.
- Animal Motifs: The Spider, his armor has this theme.
- Arch-Enemy: Of the entire Dragon Lineage.
- Asskicking Equals Authority: Genshin not only is the Master Ninja for the Black Spider Ninja Clan, but he is so strong, stronger than any other the Spider Clan ever had, with this Genshin just had to be appointed as their leader.
- Back from the Dead: Died in his third fight against Ryu, Elizébet resurrected Genshin as a Vazdah Greater Fiend.
- Badass: Genshin reeks of badassery, leading the Black Spider Ninja Clan through sheer power and proving his skills are worthy of a Master Ninja.
- Benevolent Boss: While Genshin is credited for being a ruthless and violent Overlord, many Spider Ninjas seems to adore and respect him, many Spider Clan scrolls will note how respectable Genshin is.
- BFS: Blade of The Archfiend.
- Dark-Skinned Blond: A male variation.
- Driven by Envy: The Black Spider Ninja Clan being in the Dragon Ninja Clan's shadow for generations took its toll on Genshin, he grew to hate Dragon Lineage entirely, their downfall is Genshin's ultimate goal.
- It's Personal: Genshin's entire motivation for going along Elizébet plans, he really wants the Dragon Lineage to be extinct.
- Large and in Charge: Genshin borders on giant, even towering some of his Ninjas that were converted into fiends while still a human, and of course Genshin is the one in charge.
- Lightning Bruiser: Powerful and fast, very fast; Genshin is just too damn fast, an athletic Ninja like Ryu has to keep his eyes focused against a giant like Genshin due his speed.
- Mirror Boss: To an extent - he can use the Flying Swallow, the counter-attack, the Piercing Void Ninpo (in Sigma II only), has an Ultimate Technique similar to Ryu's in Greater Fiend form, and Ryu picks up his Underworld Drop after getting the Blade of the Archfiend.
- Ninja: Holds both Master Ninja and Clan Leader status.
- One-Winged Angel: Coming back as a Vazdah Greater Fiend.
- Playing with Fire: Genshin's primary elemnet for his Ninpo is fire.
- Recurring Boss: You face off with him four times in the game.
- Take Up My Sword: In his last breath Genshin passes the Blade of the Archfiend to Ryu, he uses it along with the True Dragon Sword in Ninja Gaiden II.
Debuting in: Ninja Gaiden II (Xbox 360) as Sonia
The main girl for Ninja Gaiden II (Xbox 360} and Sigma II
, Sonia is Irene Lew
under an alias during the events of the second Xbox game, again she is a CIA agent tasked with teaming up with Ryu Hayabusa to prevent the Archfiend from returning. Different from her NES counterpart, Sonia is not so harmless, she proved herself to be quite dependable and gutsy when fiends are not involved; when fiends are involved however, Ryu is up to task and ready to rescue Sonia. Notable for her small red tatoo above her breasts and beautiful body figure as a whole, Sonia's design sticks for Irene Lew during the Dead or Alive series
- Action Girl: She can prove herself when fiends are not involved.
- Action Girlfriend: Teaming up with Ryu with her bazooka, she's really Irene Lew under an alias so it's official.
- Adaptation Dye-Job: Sonia's hair color is what sticks for Irene Lew as seen in Dead or Alive.
- BFG: The bazooka Sonia uses to aid Ryu.
- Continuity Nod: Just the fact that Sonia was confirmed to be Irene Lew in Dead or Alive served to really tie the Xbox series as happening before the NES series, Itagaki in his last days at Tecmo was really contradicting about the series continuity.
- Distressed Damsel: When captured by Elizébet and later by Alexei.
- Fan Service Pack: When she was revealed to be Irene Lew in Dead or Alive, Sonia became the embodiment of this, literally.
- Faux Action Girl: While playing the CIA Agent role better than her NES counterpart, Sonia can fall in this quickly when greater threats are involved.
- Guns Akimbo: She wields two gns at the beginning of the game and actually succeeds in killing two Black Spider Ninja.
- Mission Control: For Ryu as of Dead or Alive.
- Ship Tease: Sonia was the only girl in the Xbox series whom Ryu showed some afftection for, he was really worried about her in the Underworld and they shared a good hug in the end.
- Suspiciously Similar Substitute: Sonia, a CIA agent tasked to work with Ryu, who frequently straddles between Action Girl and Faux Action Girl to Distressed Damsel status in the modern series replaces Irene, a CIA agent tasked to work with Ryu, who frequently straddles between Action Girl and Faux Action Girl to Distressed Damsel status in the NES trilogy. In fact, they were so similar that eventually in Dead or Alive: Dimensions it was revealed that Sonia was Irene's alias during the events of Ninja Gaiden II, making Sonia and Irene one and the same for good.
Debuting in Ninja Gaiden III (Xbox360/PS3/Wii U)
Mizuki's daughter. She is a bit afraid of Ryu at first but quickly gets a liking to him.
- Attack of the 50-Foot Whatever: That monster you slay at the beginning of vanilla Ninja Gaiden III ? Yeah, it's her.
- Break the Cutie: She doesn't take Ryu killing her father very well.
- But Not Too Foreign: She's a quarter Japanese, three-fourths-English.
- Cute Mute: She uses her cell phone to communicate most of the time. She regains her speech near the end of the game.
- Distressed Damsel: She gets captured twice.
- Final Boss: Transformed as a goddess and equipped with the Dragon Sword.
- Happily Adopted: Mizuki is actually her biological aunt, but Canna doesn't really care about that.
- Morality Pet: Becomes one for Ryu.
- My God, What Have I Done?: After Ryu manages to change her back to normal, she is shown to be remorseful over what she said to him prior to her transformation.
- One-Winged Angel: Rather unwillingly, courtesy of her uncle.
- Parental Abandonment: Her parents died in an accident when she was very young. (Mizuki is her biological aunt, adoptive mother.) The resulting trauma caused her muteness.
- Shipper on Deck: She really wants Ryu to be her daddy, which implies being more than Just Friends with Mizuki. For bonus points, they are literally on a deck when she says it to him.
- You Killed My Father: "MURDEREEEEER!!!"
Clifford "Cliff" Higgins
Mizuki's Brother-in-law. She jokingly describes him as a Mad Scientist
since he conceives strange advanced weapons such as Ryu's target-locking bow
. Turns out, he really is a Mad Scientist, responsible for bringing his brother Theodore back to life as the Regent of the Mask and turning Canna into what he calls a "Goddess".
The second Canon Immigrant
from the Dead or Alive
series, debuting in the re-release for Wii U Ninja Gaiden 3: Razor's Edge
as a free DLC character. Although she also got a very brief cameo in Sigma 2
, but only as The Faceless
Kasumi is the younger sister of Hayabusa's childhood friend Hayate, from the Mugen Tenshin Clan. She's also Ayane's older half-sister. In the Dead or Alive
series, Hayabusa watches over her after she became a runaway ninja for avenging her brother.
- Absolute Cleavage: When she wears her traditional blue and white costumes.
- Action Girl: She already showed this trait in her own series, but here it shines even more.
- Badass: Again, cutting her enemies in half without flinching makes her look this even more than in Dead or Alive. Which is saying something.
- Badass Adorable: She doesn't get to show her kind personality, but she's still a cute as ever.
- Badass Cape: With her default costume. Specially created for Razor's Edge.
- Badass Princess: Or rather "Badass Heir of a Ninja Clan".
- Beware the Nice Ones: Even more than in her own series!
- Braids of Action: One of her alternative hair styles.
- Brown Eyes: To illustrate her kind temper and that she's more down to earth than her half-sister.
- Canon Immigrant: From the Dead or Alive series.
- Cherry Blossoms: Her motif, and appear from time to time while she fights.
- Cleavage Window: With her default costume, formed between the Ninja Catsuit's cleavage itself and her Badass Cape.
- The Faceless: Her cameo in Ninja Gaiden Sigma 2. We only get to see her from her back.
- Finishing Stomp: Her version of the Izuna Drop, which is a variation of one of her grabs from the Dead or Alive series. She stomps her victim's head again and again in mid-air until she finally crushes it to the ground.
- Fuuma Shuriken: She can combine her throwing knives to create one, including a Precision-Guided Boomerang effect. If fully charged, it can cut any enemy in two through the waist.
- Flash Step: Another of her trademark moves, albeit here appears as a game mechanic common to all characters.
- Good Is Not Soft: She's still the nice, kind, Reluctant Warrior she was from her own series. Gentle however does not enter into the equation, she's basically a human ginsu that shows even the Mortal Kombat characters how disemboweling into itty bitty pieces is done.
- Highly-Visible Ninja: Albeit her costumes don't stand out as much as the other female characters, she's still not very concern with being seen.
- Hime Cut: Her other alternative hair style, and arguably the most popular one.
- Kamehamehadoken: Her Ninpo, the Rending Wind. Its effect is similar to the Piercing Void, with the possibility of an additional radius attack at the end.
- Jack of All Stats: Similar to how she is in Dead or Alive, she is very balanced and has a lot of tricks up her sleeves.
- Lightning Bruiser: She can potentially be one of the best characters in the game in the hands of an advanced player. Whilst she doesn't have Ryu's ease of use nor his defense, she does have deadlier moves, just tricky to pull off. She's also the second fastest character after Ayane.
- Katanas Are Just Better: Her famous wakizashi from Dead or Alive gets upgraded to a katana (although its length is closer to a ninjato).
- Kunoichi: And a pretty high ranked one in her own clan. Or at least, she used to.
- Lady of War: Despite being so young, she has a distinctive grace, even in her bloodier moments.
- Panty Fighter: Three of her four costumes in Razor's Edge leaves her panties visible.
- Real Life Writes the Plot: Itagaki was the sole reason Kasumi never appeared in Ninja Gaiden since day one, the creator was very vocal when saying his daughter Kasumi isn't the type of person that engaged in the same brutalities as Ryu did, phrasing that she was too pure for this, by the time Kasumi cameo'd in Sigma II Itagaki was no longer part of Team Ninja/Koei Tecmo, he had already lost the reigns on his "daughter".
- Redheaded Heroine: Although she's only a Guest Character in Razor's Edge, she's the protagonist of the Dead or Aliveseries.
- Reverse Grip: She wields her katana this way, which is actually how ninjas usually wielded their ninjatos in Real Life.
- She-Fu: Her agility is a view to behold.
- Spy Catsuit: Her default costume in Razor's Edge, which comes from Dead or Alive 5 (and looks suspiciously similar to the one Hayabusa wears), plus a blue cape to boot.
- Stock Ninja Weaponry: A ninjato-length katana, kunais (although the ones she actually trows look more like Western knives) and a Fuuma Shuriken (formed by said knives).
- Teleport Spam: A prominent aspect of her fighting style.
- Tomboyish Ponytail: Her default hair style.
- Took a Level in Badass: Or rather 'conformability in gore'. Previously, Kasumi was usually reluctant to fight unless there was no other choice. Now she seems okay in splattering the blood of evildoers at first sight. Could be justified that during Tecmo's run with Itagaki, he explicitly wanted to avoid a bloody and gory environment for Kasumi. Since he left...
- True Blue Femininity: She leans toward this more than in her original series (the prominent blue cape in her Ninja Catsuit, her iconic blue kimono and another, more traditional woman kimono).
- What Happened to the New Costume?: In Sigma 2 she wears a variation of her traditional blue costume. Although we only got to see the back side, fans really liked it and many of them were eager to see it properly. Too bad it hasn't appeared ever since, neither in Razor's Edge nor in the Dead or Alive series.
- Woman in White: Her famous second costume from the Dead or Alive series is available in Razor's Edge.
- Zettai Ryouiki: In her traditional blue and white costumes.

He is also Canna's father and Cliff's brother, brought Back from the Dead, brainwashed and used by LOA. He comes back to his senses and helps Ryu at the end of the game.
