- Anti-Villain/Hero Antagonist: They only attacked Inuyasha because Tsubaki tricked them into doing so. When they realize that Tsubaki duped them and are defeated, they stop.
- Color-Coded Characters/Red Oni, Blue Oni: Botan wears blue while Momiji wears red. Their hair colors and eyeshadow match their clothing as well.
- Curb-Stomp Battle: Given their apprentice status, Inuyasha and co. are more than a match for them.
- Cuteness Proximity: They're smitten with Shippo and Kirara from the minute they lay eyes on them, and as soon as they're convinced that the two aren't evil, they begin fawning over them.
- Horrible Judge of Character: They instantly trust Tsubaki of all people after she reveals herself to be a priestess.

- Sympathetic Magic: They make giant doll replicas of Inuyasha and Kagome by getting ahold of locks of their hair.
- Sympathy for the Devil: Even after discovering her true colors, Momiji still expresses pity for Tsubaki.
- Unwitting Pawn: Of Tsubaki.

Voiced by: Hiroshi Matsumoto (JP), Lee Tockar (EN), Alberto Caneva [Izumo] and Roberto Draghetti [Gyu Oh] (IT)
- Adaptational Villainy: In the English dub he's portrayed as a full-fledged villain, while in the original dub is clear that he's just driven by his madness.
- Carry a Big Stick: As Gyu Oh wields a wooden club embedded with fake Shikon Jewels.
- Genius Bruiser: Oxen and bovine creatures are usually portrayed as dumb or stupid, but Gyu Oh is far from this stereotype, as he managed to built several artificial (though weaker) Shikon Jewels.
- Half-Human Hybrid: Half-bull demon. Unlike most other half-demons in the series, his father was the human and his mother the demon.
- Hoist by His Own Petard: He ingests a large quantity of his fake Shikon Jewels to go One-Winged Angel and fight Inuyasha, but the toxic properties of the fakes end up killing him by sunrise.
- Jekyll & Hyde: A more radical variation.
- A Load of Bull: He's a minotaur
- Tragic Monster: Izumo is genuinely a good person, but, y'know, turning into a savage bull demon every single night will probably be bad for your sanity.
A moth demon and the brother of Gatenmaru.
Voiced by: Tomokazu Seki (JP)
- Avenging the Villain: Defied: he laughs it off when Inuyasha asks him if he's coming after them to avenge Gatenmaru's death.
- Even Evil Has Standards: He finds Gatenmaru's tendency to suck human blood abhorrent.
- Facial Markings: Red stripes on his cheeks.
- Guyliner: Wears purple lipstick.

Once a powerful ninja demon, he was in love with Tsukiyomi, a human woman. However, he was possessed by the dark powers of the Naginata of Kenkon, forged by Kaijimbo, and turned evil.
Voiced by: Kazuya Nakai (JP), Giuliano Bonetto (IT), Salvador Delgado (Latin America)

- Heel–Face Turn: Did one, thanks to Tsukiyomi. However, it didn't last thanks to the Naginata.
- Omnicidal Maniac: When possessed by the naginata, he decides to create a black hole to destroy humanity and possibly all of existence. This is especially jarring, especially most of the villains just want power, killing and eating.
- Outside-Context Villain: Most villains including the Big Bad are merely selfish egotists that want things their way and kill whatever disrupts them. It's jarring to see a villain that wants to destroy everything due to personal tragedy.
- Suicidal Cosmic Temper Tantrum: He thought Tsukiyomi betrayed, so he decided to destroy all humanity with a black hole, thanks to the naginata.

- Blessed with Suck - Cast from Hit Points: She had to use her spiritual abilities constantly, which greatly weakened her. Hoshiyomi got his Evil Weapon to actually support her so she wouldn't have to use her power in excess!
- Grand Theft Me: Heroic example. She possesses Kagome's body to try talking to Hoshiyomi, but he's too consumed by his rage and power so she channels what's left of her powers through her so Inuyasha and Co. can finish him.
- Magical Girl Warrior: She's both a skilled naginata user and a Barrier Maiden able to purify spirits.

- Not So Different: There are some parallels between her and Naraku. Both of them made deals with hordes of demons to either gets the affections of those they were in love with, or destroy them while trying. However, Sara was far more sympathetic than Naraku for obvious reasons.
- The Ojou
- Parental Marriage Veto: While Sesshoumaru wasn't planning to marry Sara, her father Souju heard that she liked Sess and tried to pull this. Things went From Bad to Worse immediately afterwards.
- Rescue Romance: Subverted. Sesshoumaru didn't rescue her, he mostly happened to be passing in the middle of the army.

- Badass Cape: Has one in the form of wings.
- Barrier Warrior: While in Chrisalys mode.
- Big Bad: Of the first movie.
- Bishōnen: Till he transforms.
- Cool Sword: Actually a pretty normal broadsword, though he does use it to deflect Inu Yasha's Wind Scar.
- Dance Battler: His fighting style, not surprisingly since his origins are in China.
- Dangerously Genre Savvy: In order to release the power of his father, he decides to kidnap Kagome in order to instigate Inuyasha into doing a Leeroy Jenkins so he'd release his father for him, and also take control of Kirara and Kagome to gain an advantage while he's metamorphosing into the next Lord Hyoga. Also has his minions attack Sesshomaru just to find out whether he has the sword capable of releasing his father's power, and has one of them copy Miroku's power so they'd cancel each other out in case he tries to use it to not of being sucked into the Wind Tunnel.

- Hoist by His Own Petard: Death by Bakuryuha.
- Legacy Character: His goal is to literally become the same being as his father.
- Lightning Bruiser: While by no means as fast as Sesshomaru, he was able to outpace Inuyasha in their first bout.
- Manipulative Bastard: In a particularly mean way: brainwashes Kagome into killing Inuyasha in the same manner as Kikyo. More generally, everything in the movie is all part of his plans; he also takes advantage of Inuyasha's Leeroy Jenkins tendencies to release his father.
- One-Winged Angel: After becoming the New Lord Hyoga, he turns into a colossus with moth wings and antennae.
- Poisonous Person: As a moth, it's obvious.
- Sealed Evil in a Can: Was sealed in a tree, along with the remains of his father.
- Smug Super: The reason he doesn't need the Shikon Jewel for a power booster, is that, like Sesshomaru, he already has power to back his claims.

- Not So Stoic: After merging with his father.
Ruri and Hari
Menomaru's servants who aid in his evil plan.

- Didn't Think This Through: Ruri really should have done more research on the Wind Tunnel before she copied it.

- Hoist by His Own Petard: Ruri who tries to even the deadlock against Miroku's Wind Tunnel by expanding hers. However she winds up losing control and ends up sucked into it.
- Power Copying: Ruri who copies Miroku's Wind Tunnel for her own.

- Badass Princess: At least pretends to be one

- Cool Sword: Makes a giant golden sword out of her hairpin.

- Manipulative Bitch: No Naraku by any means, but is still very manipulative
- No Body Left Behind: Deprived of the Celestial Robe, she's hit by Inu Yasha's attack and turns into a handful of cherry blossoms.
- Noodle Incident: It's implied she had an old score with Naraku in the past, but it is never elaborated upon. All that is known is that they were both enemies of Miroku's grandfather, and whatever grudge they had with each other was serious enough for Naraku to fake his own death simply to lure her out of hiding.
- Sealed Evil in a Can: Was sealed in a mirror. She spend the first part of the movie still inside it.
- Time Stands Still: The effects of the Eternal Night.
- Vain Sorceress

A clone of Kikyo who had been hibernating in an artificial womb for 50 years. She was created from a blood sample taken from the real Kikyo 50 years prior to the events of the movie to do the Shitoshin's bidding. She is a soulless body with no will of her own. She is unleashed to seduce and kill InuYasha but is easily taken out by the real Kikyo.
- Ambiguously Human: Revealed to have fangs prior to her demise.
- Artificial Human
- Cloning Blues
- Composite Character: A clone of Kikyo who wears Midoriko's clothing and wields the latter's Weapon of Choice.
- Deadly Hug: When Inuyasha can't kill her, she embraces him and seems poised to bite into his neck before the real Kikyo shows up and takes her down.
- Dropped a Bridge on Him: She's foreshadowed throughout most of the movie but killed very quickly and effortlessly by Kikyo.
- Emotionless Girl: She has no will of her own and wears a blank expression on her face.
- "I Know You're in There Somewhere" Fight: Inuyasha initially tries this on her, but gives it up when he realizes it's not the real Kikyo.
- Innocent Fanservice Girl: She's completely naked for most of the movie. There's a few camera pans showing off her butt and legs.
- Lightning Bruiser: Unlike the real Kikyo, she wields a sword and is fast and strong enough to physically fight Inuyasha on an even footing.
- Naked on Arrival
- Shapeshifter Guilt Trip: Inuyasha manages to overpower her, but can't bring himself to finish her off; the real Kikyo shows up at that moment and kills her before berating Inuyasha for letting himself be tricked by the fake.
- The Speechless
The protagonist of the DS game "Secret of the Divine Jewel."
- But Not Too Foreign: She's an American exchange student, but was initially born in Japan before immigrating to the U.S.
- Everyone Loves Blondes: Several characters in-game remark on how pretty her hair is.
- Naginatas Are Feminine: Her weapon of choice.
- Reincarnation: She's the reincarnation of a demigod child of the storm god Datara.
- Shock and Awe
- Token Minority/America Saves the Day: She's the first and so far only American to be featured in the entire Inuyasha franchise.
The protagonist of the PS2 game Secret of the Cursed Mask.
- Audience Surrogate: Oh heck yes, and a rather awesome example, at that. He/she quickly becomes very useful thanks to the Shikigami powers and is integral in solving some of the major problems that come up (for example, one of his/her powers is essential to taking away enemy barriers so attacks will actually damage them). He/she's the "player character". Not to mention that given that Kururugi can "hook up" with one of the members of the group, he/she's also a "fanboy/fangirl surrogate". Although that last part's kind of spoiled during the ending when Kururugi is sent back to the modern era...unless it's Kagome's ending, since of course Kagome lives in the modern era as well, so they can meet up pretty quickly.
- But Now I Must Go: How his/her story arc ends.
- Calling Your Attacks: Since Kururugi must rely on the powers of Shikigami in order to use any of his/her moves, every attack gets its own phrase.
- Canon Name: The default names of the male and female Kururugi are Michiru and Kaname respectively.
- Character Development: When Kururugi is first sent to the Feudal era, he/she's a fish out of water and is upset that there are no supermarkets around and his/her cell phone doesn't work. Then he/she is granted "Shikigami" powers, and eventually develops into a brave warrior in his/her own right. Also, in another example albeit a more minor case, Kururugi eventually learns (through his/her optional "romance" arc should the player choose to become especially close to a specific member of the group) to be more true to his/her feelings.
- Guide Dang It: It's possible for Kaname (and not Michiru, since he isn't gay or bisexual) to end up with Sesshomaru of all people... but that requires a convoluted effort to not only not build up much affection with the other group members but also to do all the Sesshomaru events in the right order when you get them so you don't miss any. And at one point you have to choose to worry about Rin instead of your friends, but the impact of the choice isn't apparent right away. You'll only know you're on the right track if the "profile picture" on your save file suddenly has Sesshomaru's picture on it instead of one of the group members' pictures.
- On the other hand, it can be surprisingly easy to get the Sesshomaru ending, even if you wanted to get a different ending. All that's required is to worry about Rin and trigger the random event on the road to Castle Town when it's available towards the end of the game; seeing the other random events involving Sesshomaru is not necessary.
- Hello, [Insert Name Here]: Because the player can change Kururugi's first name, said first name is never uttered during audible dialogue. As shown in the opening cutscene, s/he's apparently on a Last Name Basis with his/her friends.
- Level-Up at Intimacy 5: Michiru/Kaname Kururugi can learn more "team-up" techniques depending on which member of the group Kururugi chooses to spend his/her days off with. (This is also indirectly how the others learn different "team-up" techniques, since if Kururugi pairs up with one of the group, the rest of the group must then pair up with different people for their days off).
- Nice Guy\Nice Girl
- Schrödinger's Player Character: Some plot details change slightly depending on whether you pick Michiru, the boy, or Kaname, the girl. For example, the senior citizen "Kakuju" whom you meet early in the game is an old woman if you pick Michiru, and an old man if you pick Kaname, so Kakuju is always the opposite sex of whomever you pick as the player character. Likewise, if you pick Michiru, the antagonist "Utsugi" turns out to be a man, and it's a fake person who looks like your identical ancestor. Utsugi is also your identical ancestor (not really) if you pick Kaname, but Utsugi is female instead. So unlike Kakuju, Utsugi is always the same sex as whomever you pick as the player character. This is a major plot point; you find out near the end of the game that Kakuju and the real Utsugi were lovers, but Utsugi died and Kakuju created fake versions instead. And since the real Utsugi is your identical ancestor, this is why both Kakuju and Utsugi are each a different sex depending on whom you pick.
- Squishy Wizard: S\He serves as this to the group.
- Took a Level in Badass
The Big Bad of Secret of the Cursed Mask alongside Naraku, and the one responsible for Kururugi's arrival in the feudal era. Like Kururugi, his/her gender is chosen by the player.For the sake of clarity, Utsugi will not be referred to by any gender-specific pronouns.
- Artificial Human: Utsugi is actually a Hitogata, an enchanted clay doll created in the image of the real Utsugi.
- Big Bad: Part of a Big Bad Duumvirate with Naraku.
- Blood Knight: In their first encounter with the gang, they injure Inuyasha and remark that his wounds are "beautiful like the setting sun."
