Myoga the flea youkai was once a servant of Inuyasha's father, and tries to help Inuyasha and his friends by providing useful information, although he is a coward and a bit of a lecher. He claims Inuyasha's blood is delicious, and often appears by biting Inuyasha to drink some of his blood, usually resulting in getting squashed by Inuyasha.

- Animal Motifs: The flea.
- Arranged Marriage: Kind of in the anime. He got roped into a wedding with an energetic lover, but seems none too happy about it and escapes.
- Butt Monkey: Everyone is always making fun of his cowardice and swatting him.
- Deadpan Snarker
- Dirty Coward: Books it whenever there's danger.
- Expy: Of Happosai, though he's much less perverted. Made much more obvious in the English and Latin-American dubs, where the two characters are played by the same actors.
- Lovable Coward: Will no doubt run when the going gets especially tough, but only because he's a puny flea with barely any combat potential other than sucking a demon's blood dry over the course of several hours.
- Mentor Archetype
- Mr. Exposition
- Nigh-Invulnerability: He's still kicking despite being repeatedly squashed flat.
- Old Retainer
- Really 700 Years Old: It is never stated how old he really is.
- Running Gag:
- Usually, when Myoga shows up, he tries to nibble on Inuyasha's blood, to which Inuyasha retaliates with a firm swat to the flea, which sends him sailing to the ground like a flattened sheet of paper. A few times, it clues the gang in to his sudden, unseen arrival.
- His Lovable Coward tendencies - specifically his habit of abandoning whichever party member he's perched on if it looks like they might be in danger - are also played as a Running Gag, to the point that in at least one instance Myoga moving from one character's shoulder to another character's is taken as a warning sign, and the first character is advised to move where it's safer.
- Suck Out the Poison: On more than one occasion, he saves Inuyasha and co. from dying by sucking poison out of their systems.
- Supernaturally Delicious and Nutritious: According to him, Inuyasha's blood which he inherited from his father.
- Trademark Favorite Food: Inuyasha's blood.
- Third-Person Person: He does sometimes speak in terms of "This Myouga" in the Japanese dub.
- Youkai: A flea youkai.
As a miko and the Shikon Jewel's guardian, Kikyo's responsibility was to purify the Shikon Jewel and keep it out of anyone else's hands. Falling in love with Inuyasha, however, led to her death, and she had the Jewel burned with her body in order to protect it, causing it to reappear within the body of her reincarnation, Kagome. However, this is not the last we see of her...

- Adaptational Villainy: Kikyo is far more antagonistic in the anime, whereas in the manga she and Inuyasha reconcile much more quickly.
- All-Loving Heroine: She was an unadultered version of this, until she died. She still retained some of the traits after being forcibly revived and becoming a Dark Magical Girl, helping the poor and disinherited whenever she could and helping Saint Hakushin to finally let go of his hate and despair.
- Aloof Ally: Eventually she becomes this to Inuyasha and Kagome.
- Aloof Big Sister: Towards Kaede, and to Kagome to a degree.
- Aloof Dark-Haired Girl: She is tall, beautiful, dark-haired, pale-skinned, and extremely aloof.
- Always Someone Better: Kikyo fills this role for Kagome and Tsubaki.
- Anti Heroine: While a good person at heart, she's too manipulative and aloof to be a 100% traditional hero.
- Anti Villainess: At first after her resurrection. She eventually becomes an Anti Heroine.
- Archer Archetype: Travels on her own, is aloof and tends to appear out of nowhere surprising everyone with a perfect shot.
- Artificial Human: After revival; her body is made from her ashes and clay and sustained by the dead souls of women.
- Back from the Dead: She's revived by Urasue to help her find the Shikon shards.
- Bad Powers, Good People: After her resurrection, she has to periodically absorb dead souls to be able to move but is otherwise a heroic and good person.
- Badass: One of the most powerful characters in the series, and one of the few whom Naraku considers a genuine threat.
- Big Sister Instinct: She is very protective of her little sister Kaede.
- Bloodless Carnage: Justified; as her body is composed of clay, Kikyo has no blood to shed.
- Broken Bird: Particularly after her resurrection. She constantly angsts over her current condition and the events that led to it.
- Broken Messiah: After being revived, she angsts at the world and "Inuyasha" for killing her. Really not helped by how the world has changed.
- Brought Down to Badass: According to the filler episodes 147 and 148 of the anime, her powers were weakened somewhat thanks to Tsubaki's curse. She's still pretty powerful, though.
- Came Back Wrong: She's resentful and the only thing that keeps her going is revenge.
- Chronic Hero Syndrome: Dead or alive, she never hesitates to help someone in need.
- Cooldown Hug: On Saint Hakushin.
- Damaged Soul: Once the resurrected Kikyou regains part of her soul, she goes from an Empty Shell to consumed by the rage and bitterness with which she'd died. Her first act is to blast Urasue, who'd resurrected her, into oblivion, and she spends quite awhile afterwards trying to kill Inuyasha, Kagome, or both together. While she might have gained balance with her full soul, most of it reverted to Kagome. Which was why in all her later appearances Kikyou had to take the souls of recently deceased women to survive. Whether she destroyed those souls in the process, or merely borrowed them temporarily before letting them pass on, is never made clear, but aside from the soul-eating bit she eventually focuses her attention on destroying Naraku, who should have been the target of her anger in the first place.
- Dark Action Girl: She's not super bloodthirsty when fighting, but is still rather aloof and more merciless than Action Girl Sango and Action Survivor —> Action Girl Kagome.
- Dark Magical Girl: She has holy powers like Kagome, but is more mature, more powerful and more vicious. Extra points for being Kagome's previous incarnation. She spends the early seasons as an antagonist but later becomes a hero.
- Defrosting Ice Queen
- Does Not Like Shoes: In the manga only. Averted in the anime, where she wears standard tabi socks and sandals.
- Don't Make Me Destroy You: In her early interactions with Inuyasha she would simply pin him to a tree with her arrows while warning him to stay away from her and the Shikon no Tama. Subverted, however; she only restrained him and always held back from dealing the killing blow.
- The Dreaded: Out of all of his various foes and pursuers, Kikyo is the only one whom Naraku considers any sort of serious threat.
- Eerie Pale-Skinned Brunette: Black hair, pale skin and her current self is actually a body made from her ashes and clay that came to life with a resentful fragment of her soul.
- Evil Counterpart: In the start, she looks this to Kagome. Ends up turning into the Anti Heroine counterpart
- Friend to All Children: One of her most consistent traits, either alive or undead.
- Guile Heroine: When she took the Jewel from Kagome and gave it to Naraku... but only to lull him into a fake sense of security rather than help him. Unfortunately for her, he killed her before she could complete her task, but in the end her plan worked as that's how Kagome killed Naraku. Kikyo just wasn't as ruthless as she thought she was and was unwilling to let Kohaku get killed by Naraku in exchange for purifying the Shikon no Tama, since she was a bit more Ax-Crazy when she came up with that plan. Also, no one planned for the Shikon no Tama trying to grant Naraku's wish by trying to pull Kagome into itself with his soul.
- Handicapped Badass: She's one of the most powerful characters in the series, but she's hampered by her clay body. Hitting her with enough force or depriving her of her accumulated souls is enough to incapacitate her.
- Hime Cut: The fitting hairstyle of a Miko.
- Holy Hand Grenade: She is one of the most powerful priestess in the series. Her holy power is rivaled only by her Reincarnation Kagome unsealed, Hitomiko, Midoriko and Saint Hakushin.
- Humans Are Bastards: Says something to this effect when revealing that Onigumo/Naraku set them against each other purely out of jealousy of Inuyasha for being with Kikyo:Inuyasha: He was jealous? Over something so ridiculous?
Kikyo: Yes, ridiculous. But that's what mortals are.
- I Just Want to Be Normal: Before her death, she told Inuyasha more than once that she wanted to live as a normal girl instead of as a priestess and guardian of the Shikon Jewel.
- Idiot Ball: She picks it up when she gloats to Naraku that he can't kill her as long as he contains Onigumo's heart and human emotions. Naraku spends a good chunk of the series trying to discard said emotions and do just that, eventually succeeding.
- Ill Girl: Took this role more than once, despite being undead. Namely, more than once she was either weakened by poison, suffered the physical downsides of having a clay body, or was separated from the Soul Collectors that kept her "alive."
- Informed Attribute: In the manga, she and Kagome do indeed look very similar. In the anime however, their designs are both subtly altered and they don't look much alike at all — at a glance, Kikyo has a different hairstyle, smaller eyes, and paler skin compared to Kagome.
- Inhuman Human: After her resurrection, and she's not happy about it.
- It's Personal: Naraku tricked her into thinking Inuyasha had betrayed her and killed her, specifically by disguising himself as Inuyasha, fatally wounding Kikyo, and then, while still in Inuyasha's guise, taunting Kikyo for being stupid enough to believe that Inuyasha loved her.
- Jerk with a Heart of Gold: She's considerably more bitter and resentful than she was when she was alive, but is still a good person.
- Lady of War: A composed and graceful archer.
- Last Kiss: She and Inuyasha share a last kiss right before she definitely dies.
- The Lost Lenore: To Inuyasha, much to Kagome's chagrin.
- Mage Marksman: Magic Ranger, a trait she shares with Kagome.
- The Magic Touch: She can use her purification powers to burn opponents such as Inuyasha and Urasue with a touch, and once paralyzed Kagome by touching her forehead.
- Magical Gesture: Kikyo uses what seems to be a mudra (first two fingers straight out, next two curled, with the thumb touching the top of the third finger) when focusing her spiritual powers.
- Miko: And quite powerful.
- Naked on Revival: Is completely nude upon being resurrected by Urasue.
- Never Found the Body: After her confrontation with Naraku in Mt. Hakurei.
- No Good Deed Goes Unpunished: The whole plot of the series began because she decided to show compassion to a crippled bandit and help care for him. What does Kikyo get in return? Said bandit makes a Deal with the Devil to become a half-demon, then mortally wounds her while duping her into thinking that Inuyasha, her lover and the first one to ever treat her like a person, had betrayed her. It's all downhill from there.
- Not So Different: When Inuyasha was trying to steal the Jewel from her, she repeatedly spares Inuyasha because she sensed that Inuyasha felt all alone just as she did.
- Not So Stoic: Generally calm and aloof, but when she believes that Inuyasha betrayed her, she is absolutely pissed and makes no effort to hide it.
- Out-Gambitted: She tried to lull Naraku into a false sense of security by giving him the portion of the Sacred Jewel Kagome had been previously holding onto in order to destroy both him and the jewel was it was completed. This made Naraku stronger which made him able to kill her. In the end, her plan worked though, she wasn't as ruthless as she thought she was in order to pull it off.
- The Power of Hate: After Kagome regains her soul, Urasue claims that Kikyo is only kept going by her hatred of Inuyasha for his perceived betrayal.
- Power Glows: With her arrows.
- Rapunzel Hair: Her hair reaches her hips when let down.
- Raven Hair, Ivory Skin: She has black hair, pale skin, and is considered beautiful by many other characters.
- Revenge Before Reason: Even after Kagome informs her that Naraku set them up and that Inuyasha still loved her, Kikyo flat-out states that she doesn't care because it won't bring her back. Eventually, however, she is able to accept this and focus her efforts on Naraku.
- Roaring Rampage of Revenge: Her immediate priority after revival is to try to kill Inuyasha for his perceived betrayal.
- Sacred Bow and Arrows: As a priestess, she can fire arrows infused with holy energy.
- Soul Fragment: Between her and Kagome's shared soul, she only has a little fragment.
- The Stoic: Nearly always cool, calm, and collected.
- Sugar and Ice Personality: She acts cool, collected and aloof, but she's still a good-natured person at heart. Her death just made her much more bitter.
- Taking You with Me:
- Fatally injured, she tries to do this to InuYasha, who she believes had betrayed her (it was actually Naraku in disguise). At the last second, she seals him with a spell that would make him sleep eternally without aging or decomposing instead of killing him.
- After her revival, she attempts to drag Inuyasha down to hell with her. She gets better, however.
- Tranquil Fury: Slays youkai and kicks Naraku's ass, all with a cool glare.
- Turned Against Their Masters: The witch Urasue resurrects Kikyo expecting her to collect jewel shards for her. Kikyo decides to burn her to death using her sacred powers instead.
- The Undead: The first notable example in the series.
- Ungrateful Bitch: After Kagome saves her from Naraku's poisoning in episode 151, Kikyo explicitly tells Kagome that she won't thank her for doing so because Kagome never considered doing anything else.
- Unwanted Revival: Urasue does this to her.
- Vague Age: The InuYasha Profiles book states that Kikyo was 18 when she originally died, whereas Rumiko Takahashi herself stated that she was "around 17" when it happened.
- Violently Protective Girlfriend: When she reunites with her Rival Turned Evil Tsubaki, who was working with Naraku at the time, she physically restrains her and tells her that, while she has little concern for Kagome's life, she will personally kill Tsubaki if she harms Inuyasha in any way.
- Wise Beyond Their Years: As mentioned above, she was 18 when she died, but she acts, sounds, and thinks like she is in her late twenties.
- Woman Scorned: Right after being revived, since she believes the man she loved betrayed her. She got better.
- Yamato Nadeshiko: Prior to her death. Eventually, as she calms down and loses her rage with the world, she develops back into a mix of YN and Dark Magical Girl in the later parts of the series.
- Yandere: Arguably, right after being revived. As said above, she got better.
- You Did Everything You Could: Towards both Inuyasha and Kagome when Naraku kills her for real; she softly reassures Kagome that even if she couldn't save her life, she nonetheless saved her soul, and when Inuyasha is breaking down over being too late to save her, she smiles and gently reassures him that the fact that he came for her is all that matters.
- Your Soul Is Mine: After her revival, and due in part to her Damaged Soul, Kikyo has to periodically absorb the souls of the dead to be able to move.
Sesshomaru is Inuyasha's elder half-brother, and unlike Inuyasha is a very powerful full-blooded youkai. He initially appears in pursuit of the sword Tessaiga, which their father had created from his own fang and left for Inuyasha to inherit; although Sesshoumaru also inherited a sword, Tenseiga, he feels he has no use for it since it is a healing sword which cannot wound anyone.
Voiced by: Ken Narita (JP), David Kaye/Michael Daingerfield (EN), Alfredo Basurto (LA SP), Niseem Onorato (IT), Phillpe Leroy (FR)
- 24-Hour Armor: Sesshoumaru never takes his armour off, not even when it's broken.
- Absurdly Sharp Claws: Like Inuyasha, Sesshomaru's main form of offense when not wielding a sword (in fact, more so than Inuyasha given that his main sword is near harmless for most of the series) are his claws, which easily slice through youkai bodies on top of being poisonous.
- Adaptation Dye-Job: In the manga, his armor is green-tinged and his sash is pink with red accents. In the anime, his armor is matte-black and the sash is yellow with purple accents.
- Aloof Big Brother: Extremely aloof, and definitely smarter, stronger, faster, more talented, refined and prettier than Inuyasha.
- An Arm and a Leg: His first fight with Inuyasha ends with Inuyasha using the Tessaiga to chop off his left arm. It isn't until the final arc that said arm grows back.
- Animal Motifs: Dogs, due to being a dog youkai.
- Anti-Hero: Adopting Rin touches off a period in which he is portrayed increasingly sympathetically, though he remains an antagonist until later in the series, with his compassion for Kagura completing his development out of being a villain.
- Anti-Villain: Type I, pre-Character Development.
- Appendage Assimilation: For a time, he tried to find a replacement for his lost left arm by using others from powerful demons; they all proved useless, and eventually he just stopped trying.
- Art Evolution: In addition to his looks, the fur over his shoulder grows progressively longer and thicker as the series progresses, going from a small boa to a gigantic tail-like mass of fur wider than his head that drags behind him as he walks.
- Badass: He's easily the strongest non-enhanced demon alive in the series, only surpassed by his father, whom he later surpasses upon receiving the Bakusaiga.
- Badass in Distress: Chapters 512-518 sees this happen. Inuyasha initially has to rescue him.
- Bad Boss: He abuses Jaken, both physically and verbally, on a regular basis, and Jaken is so damn loyal to Sesshomaru that he puts up with it.
- Berserk Button:
- When Mouryoumaru insulted Kagura in an attempt to enrage Inuyasha, he instead inflamed Sesshoumaru beyond all reason to the point that he broke his Tokijin and almost got crushed by Moryoumaru's kongosouha. Inuyasha's group, and Mouryoumaru himself, were left stunned both by Sesshoumaru's rage and the unusual recklessness of his fighting, which got him into all sorts of trouble.
- Receiving Inuyasha's pity sent him into such a fury that he transformed into his true form and, as with the Mouryoumaru incident, resulted in him making unusual mistakes on the battlefield but which set up the life-threatening injury from which he came back stronger with Bakusaiga.
- Bishōnen: Very feminine, though thanks to Art Evolution he looks more masculine in later chapters.
- Borrowed Biometric Bypass: On one occasion, he grafts a human arm to his left stump to bypass Tetsusaiga's anti-full demon barrier.
- Break the Haughty: An integral part of his Character Development.
- Byronic Hero: Lacked the compassion of his brother and overall moral restraints at first.
- Cain and Abel: Starts out as the Cain to Inuyasha's Abel. He gets better.
- Canis Major: His true form is a massive white dog with red eyes.
- Chain Reaction Destruction: Bakusaiga.
- Character Development: From villain to Anti-Villain to, arguably, Anti-Hero.
- Characterization Marches On: Character Development aside, Sesshomaru's personality was markedly different in his first appearance from his subsequent ones. He was smug, cruel, sneered a lot, and enjoyed actively mocking and insulting Inuyasha rather than simply treating him with dismissive disdain. His Stoic, Perpetual Frowner tendencies didn't appear until his second appearance.
- Clipped Wing Angel: His dog form lacks the intelligence, grace and agility of his standard form, making it easier to attack.
- The Comically Serious: Sometimes. Sesshomaru rarely loses his stoic poise, and the only times he smiles are when it bodes very, very ill for someone. Once he acquires Rin, however, it's pretty common for him to end up right in the midst of silly shenanigans involving her, Jaken, and others, made all the funnier by Sesshomaru's unrelenting seriousness.
- Cool Sword: As opposed to his brother who gets one ridiculously powerful blade with some evolving/adaptive abilities, Sesshomaru here wields a small set throughout the run;
- Tenseiga: The blade which he received from his father, the initial source of much of his animosity towards his brother. Can't harm the living, naturally enough it can strike the undead. By striking down the pallbearers of the afterlife it can revive the recently deceased... once. It, like its companion blade has a slight sentience and will protect Sesshomaru whether he wants it or not (in particular, it's meant to make sure Inuyasha can't kill him with his sword). It's revealed later, that it bears but one single offensive strike- one which banishes whatever it touches into the abyss, and it gained this ability because of Sesshomaru's feelings for Kagura. However, it turns out that Tenseiga was once part of Tessaiga and that this lone strike was meant to be given to Inuyasha, returning the blade to its original abilities. It is a simple katana in design with little flare and no transformations, it does glow blue when utilized. Still carries it at the end.
- Tokijin: The second blade he carries over the course of the series (and most artwork will see him carrying this blade, as it stays with him for much of the series). Notable for being nigh-uncontrollable for anyone save for Sesshomaru himself and though it doesn't have any distinct named strikes its power waves are more than strong enough to compensate. Distinct in design for being a moderately large broadsword/tsurugi instead of a katana. It's eventually broken by Moryoumaru after he insults Kagura's death and Sesshomaru became so upset that he attacked Moryoumaru so hard that it broke, after which Sesshomaru deems it worthless and doesn't bother repairing it.
- Bakusaiga. His final sword, gained at the pinnacle of his character development. It's not his father's or from anyone else; it's a sword formed purely from his own youki that would reveal itself only after he threw everything else away. Its only known power by the end of the series is a virus-like wave that, once struck with, will continue to eat away at its victim until there's nothing left. The damage will also transfer from person to person like a disease, enabling Sesshomaru to take out thousands of weaker demons with a single swing. He's seen with this along with Tenseiga at the end.
- Defrosting Ice King: Thanks to Rin and Kagura's death.
- Determinator: Even the reveal that the Tessaiga has a barrier that repels any demon who touches it, himself included, won't stop him from plotting ways to swipe it from Inuyasha.
- Death Glare: Dishes these out to whoever annoys him. When he gets really angry, his eyes turn red with blue irises.
- Dogs Are Dumb: In battle against Magatsuhi, he takes his true form but gets entangled in his enemy's tentacles. Jaken realises that all Sesshoumaru has to do is transform back to his smaller humanoid form to easily escape. When Sesshoumaru pointlessly shakes like a wet dog, Jaken understands that, while Sesshoumaru's dog-form gives him his full power, it also reduces his intellect to that of a dog. Word Of God has confirmed that Sesshoumaru's intelligence is his weakest ability - while he is indeed very smart, his intellect pales in comparison to his other powers.
- Don't You Dare Pity Me!: He gets pissed off when Inuyasha feels sorry for him.
- Empathic Weapon: Both Tenseiga and Tokijin.
- Establishing Character Moment: Casually rips the head off a samurai commander and then has Jaken incinerate his troops simply because he couldn't be bothered to walk around their camp.
- Evil Counterpart: To InuYasha.
- Evil Plan: Back when he was the first major villain, it was to find his father's grave and steal Tessaiga. When he mellowed into an Anti-Villain he focused less on stealing a sword and more on making one.
- Evil Weapon: Tokijin, having been crafted from Goshinki's fangs, is full of Goshinki's hate for Inuyasha, and only Sesshomaru himself can wield it without being possessed.
- Expy: Herb.
- Facial Markings: A crescent moon on his forehead and two pairs of stripes. (Also, his “eyeshadow” isn’t makeup - they’re part of the markings around his eyes.)
- Fangs Are Evil: Like Inuyasha, he has prominent canines, but you won't see them too often.
- Fantastic Racism: Like many fully-fledged Youkai in the series, Sesshomaru looks down on humans and half-demons, especially Inuyasha. Thanks to Character Development, he gets better.
- Flash Step: He leaves afterimages at top speed.
- Flight: Like many of the stronger Youkai, he has his own methods of flight.
- Good Powers, Bad People: At first after getting Tenseiga, a sword that can revive instead of kill, and he's dismayed he got it while Inuyasha got Tessaiga. After Character Development, it gradually becomes Good Powers Good People. Kind of.
- Hair-Trigger Temper: Tranquil Fury version. Totosai remarks on one occasion that Sesshomaru's temper proves that he and Inuyasha are brothers.
- Handicapped Badass: He only has one arm. For most of the series anyway. It doesn't slow him down at all. In fact, he once admits he doesn't hate Inuyasha for what happened because it's actually made him even stronger than he was before he lost it.
- Healing Factor: As a demon he has this, but he can't regenerate his lost arm or so it seemed.
- Healing Shiv: Tenseiga, which can bring back the dead. Once.
- Hidden Heart of Gold: Towards Inuyasha and Jaken.
- Hypocrite: During his debut arc, he calls Inuyasha out on his disrespect for trying to fight him in their father's grave. Inuyasha just as quickly calls him out, pointing out he has no room to talk about disrespecting their father's grave when he himself was trying to rob it.
- I Was Just Passing Through: Repeatedly does this with Inuyasha's group.
- Impaled with Extreme Prejudice: By Magatsuhi. One of his opening moves was to pierce Sesshoumaru's only arm in three places. He eventually stabbed Sesshoumaru through the chest twice.
- Implied Love Interest: To Kagura. Rin comments on it at one point.
- Inferiority Superiority Complex: Towards Inuyasha who he both resents for being the "favorite" and looks down for being a half demon.
- Instant Expert: See Master Swordsman below.
- It's Personal: Naraku used him several times to kill Inuyasha, tried to absorb him, kidnapped Rin, and killed Kagura.
- It Only Works Once: The Tenseiga can't resurrect the same person more than once.
- It Was with You All Along: Learning compassion, accepting his younger half-brother for what he is, and understanding even his vast power has limits (notably when Rin almost died for good if it wasn't for his mother) was all for the purpose of giving him what he wanted all along...a sword. The Bakusaiga. A sword born of his strength not his fathers, and potentially more powerful than any physical weapon in the series.
- Jerkass: Initially starts off as unrepentantly antagonistic.
- Jerk with a Heart of Gold: It starts with Rin, encompasses Kagura, Kohaku, then Inuyasha and his entire group. The manga eventually ends with the implication that his compassion is still growing - he still doesn't like it being pointed out though.
- Licked by the Dog: Rin's hero-worship of Sesshoumaru is the first indication of his well-buried better nature.
- Lightning Bruiser: He's faster and stronger than InuYasha
- Long-Haired Pretty Boy: So very much.
- Marked Change: In the manga, he gains three stripes on his wrists whenever he uses his dokkasou (in the anime he has two stripes on his wrists at all times).
- Master Swordsman: He's able to use any weapon to its full potential the moment he gets his hands on it. This is most evident in the few occasions when he uses Tessaiga - Inuyasha, for whom the sword was made, has to be actively thinking about protecting a human before it will change from a rusty piece of junk to a usable blade, and it takes him at least a season to master the Wind Scar to the point that he can use it at will. Sesshoumaru is able to fire off Wind Scars immediately. He gets similar results with Tokijin, Bakusaiga, and even Sango's Hiraikotsu. His own heirloom is a bit of a special case, its not that he can't make it work, he knows full well already that it's useless for what he generally prefers to do. Once he willingly lets it guide him for the first time, he has no issues with seeing and subsequently dispatching pallbearers. This is then played straight with its only combat-ready skill, which he displays unnatural speed at learning once more. This is lampshaded by Totosai, who remarks during a number of various sessions with both of them; that Sesshomaru has a gift for bringing out the latent abilities in almost every weapon he comes across while his brother must always take the long complicated route to mastery.
- Meaningful Name: His name is written with characters meaning "kill," "life" or "genuine," and "perfection," a combination which could be interpreted to mean something to the effect of "perfect killer" or "complete destruction of life."
- The Mourning After: Kagura's death filled an empty hole in his heart for the first time and he risks his life to defend her and vows to avenge her death.
- Mr. Fanservice: Even moreso than his brother.
- Mugging the Monster: Sesshomaru actually looks more humanoid at first glance than his half-demon half-brother (particularly because he doesn't have dog ears). Several people early in the series died thinking that they were attacking a human.
- Named Weapons: Tenseiga ("Heavenly Birth Fang"), Tokijin ("Demon-Fighting God") and Bakusaiga ("Explosive Crushing Fang").
- Narcissist: He's extremely prideful, confident and arrogant. It heavily hurts his ego that his father prefered to give his powerful sword to his brother, a mere half-demon, instead of him.
- Neck Lift: Does it several times.
- Nigh-Invulnerability: It is very rare that he is seriously injured, and even when he is he makes a quick recovery.
- Noble Demon: Eventually, and still in denial about it.
- No Sell: Toward poison (poor Mukotsu). Averted with Magatsuhi.
- The Nose Knows: At higher level than his brother, but is too dignified to sniff around like the former.
- Off Model: In the anime, overall positioning of the fur over his shoulder varies from episode to episode. In some scenes it's attached to his armor and looped around his shoulder while in others it's pulled up and out of an opening in his sleeve and tossed back over his shoulder.
- The Only One Allowed to Defeat You: He expresses on multiple occasions that he will be the one to kill Inuyasha, and only when Inuyasha himself is ready. Not that he ever does.
- Papa Wolf: After reviving her, he becomes very protective of Rin, so threatening her is a bad idea.
- Perpetual Frowner: Rarely smiles, and it's usually a bad thing if he does.
- Pet the Dog: His informal adoption of Rin and his attitude toward Kagura. He also saves the inu gang from being killed by Mukotsu, ostensively so that they could tell him where Naraku was.
- Pointy Ears: As opposed to his brother's dog ears.
- Poison Is Corrosive: His toxic claws.
- Poisonous Person: Able to channel acid through his claws; he used this power quite often during his first appearances, but not so much in his later ones.
- Pretty in Mink: The mass of fur hanging over his shoulder, affectionately referred to as "mokomoko-sama"note . According to Word Of God, it is actually a part of Sesshomaru's body (through which blood will flow if Sesshoumaru is injured at the shoulder), which wraps around his torso and connects to his tail when he enters his dog form. In the manga, he can use it to whip, grasp and throw opponents or carry himself through the air (the anime replaced this with an energy whip and a sparkling dust cloud respectively).
- Pride: His major flaw early on is to prove his superiority over his brother because of his noble status. This overlaps with Envy
- Rapunzel Hair: Taken Up to Eleven in the anime, where his hair reaches his knees. In the manga, his hair is only waist-length.
- Really 700 Years Old: He's biologically 19 years old despite being much older. The anime sometimes, and inconsistently, makes him look like he's in his early twenties.
- Red Eyes, Take Warning: Like Inuyasha, his eyes are golden, but the sclera turn red when he's about to transform. This is never a good thing.
- Revive Kills Zombie: Inverted. Tenseiga's abilities to slay the undead and creatures native to the netherworld can be used to revive a dead person.
- Sickly Green Glow: His poison-claws and anime-exclusive poison whip.
- Smug Super: He's so confident in his own strength and powers that, unlike nearly every other youkai in the series, he has no interest in the Shikon Jewel.
- The Snark Knight: Very condescending to everyone
- The Stoic: He's also an example of Not So Stoic as his temper is almost as short as Inuyasha's, something that was once lampshaded by Toutousai as marking them as brothers.
- Sugar and Ice Personality: Towards his followers and Inuyasha
- Supernatural Gold Eyes: Reflecting his nature as a dog-youkai.
- Super Speed: He outruns Inuyasha pretty easily. Complete with Speed Echoes in the anime.
- Super Strength: According to Word Of God, Sesshomaru's strength in one arm is equal to the strength in Inuyasha's entire body.
- Tame His Anger: What Rin and later Kagura's death did to him.
- Third-Person Person: "This Sesshoumaru", in the Japanese version; "I, Sesshomaru" in the English dub. This is a valid, if showy way to refer to oneself in the Japanese language, and, in Sesshoumaru's case, probably meant to be an aristocratic way of talking.
- Took a Level in Badass: Yes, really. You'd think losing an arm and getting a Morality Pet child companion that slowly leads him to take more of an Anti-Hero role would make him submit to Badass Decay? Wrong. When he regains his arm and gets his own, unique sword, exactly the opposite happens.
- Took a Level in Kindness: Sesshoumaru starts off an arrogant antagonist who would have thought nothing of killing Kagome and actively attempted to kill InuYasha. After he was badly wounded when InuYasha blasted him with the Wind Scar, a young human girl named Rin came across him and started bringing him food and water. Initially, he treated her with his usual cold disdain, but when he saw she had been killed by Koga's wolf youkai he looked at her with a tender expression before scaring the wolves away with a look and using Tenseiga's resurrection power for the first time to bring her back. Rin's influence and Kagura's death continue to cause him to become more compassionate as the series goes on.
- Tranquil Fury: The most anger he usually shows is a cool glare and slight frown. Especially tranquil when compared to the perpetually Hot-Blooded Inuyasha.
- The Unfavourite: A major element of his characterization revolves around his dissatisfaction with the thought that their father favored Inuyasha over himself. It's only after he moves beyond his daddy issues that he's finally able to obtain his own sword Bakusaiga.
- The Unsmile: When he smiles, it's usually not a good thing. On one such occasion, Jaken actually freaked out and literally begged Sesshomaru to beat him instead.
- Was It Really Worth It?: When he comes across Rin's body in the Underworld and discovering he cannot bring her back while undergoing his mother's test, he outright says that nothing he could have gained was worth losing her.
- Whip It Good: In the anime he can generate a poison whip made from his own youki.
- White Hair, Black Heart: Initially very cruel, but with Character Development he gets better.
- "World of Cardboard" Speech: In a battle when he learns the truth about the Tenseiga; despite not receiving Tessaiga from his father and losing an arm, he acknowledges it's allowed him to excel much more in battle just by working harder without them.
- You Gotta Have Blue Hair: Like his brother, he has white hair.
- Youkai: His true form is that of a giant supernatural dog, but he prefers to spend most of his time in humanoid form where his youkai nature is reflected in his colouration, facial markings and pointed ears. Although one of the strongest characters in the story, he only officially achieves "Daiyoukai" status after he achieves his full power and surpasses his own daiyoukai father.
Kohaku is Sango's younger brother. Apparently killed along with the rest of the youkai hunters, he reappears not long afterwards under the control of Naraku, who uses him in frequent efforts to manipulate Sango.

- Anti-Villain: Type II. Eventually Type IV.
- Back from the Dead: Naraku brought him back to life solely to screw with Sango's head.
- Badass Adorable
- Badass Normal: The jewel shard in his back does nothing but keep him alive and under Naraku's control, and he's still a skilled and efficient fighter.
- Brainwashed and Crazy
- Break the Cutie: He was a shy, gentle and somewhat frightened 11 year-old boy who was going to take part in his first demon extermination. And then he was forced to kill a lot of people (including his father), work for the one who destroyed his life and was constantly hunted for the Shikon shard in his back. After all this, he only wishes to die taking Naraku with him.
- Chain Pain: His weapon of choice is a kusarigama.
- Cosmic Plaything: Probably moreso than other characters in the series. Kohaku just cannot catch a break.
- Cute Bruiser
- Death Seeker: After regaining his memories. He first attempts suicide, and then later settles on living on until he can kill Naraku. In the end, however, he snaps out of it and decides to continue living.
- Does Not Like Shoes: When out of his demon-slaying outfit.
- Dying as Yourself: When he died, he had come to his senses after being possessed, both times. Specially jarring the second time since he had just accepted to live and fight. Fortunately he got better thanks to First Law of Resurrection
- Fighting from the Inside: When Naraku takes control of him and forces him to attack Kagome, he fights back and stops himself from killing her outright; both Inuyasha and Sango take this as proof that Kohaku still has a human heart and can still be saved.
- Identity Amnesia
- Lovable Coward: The reason Naraku is able to control him so easily is because Kohaku fears confronting his past so he just prefers to forget.
- Magic Skirt: Averted VERY BRIEFLY in the second movie.
- Mind-Control Eyes: Whenever Naraku begins to influence him, his pupils disappear.
- Morality Pet: To Kagura.
- Multi-Melee Master
- Necessarily Evil: Continues to follow Naraku's orders, even after regaining his memories, because it's the only way he can remain close enough to kill him.
- Nice Guy: Default mode when he isn't being controlled.
- Self-Made Orphan: He killed his father while possessed.
- Shrinking Violet: Before the possession.
- Shirtless Scene: Two in the second movie.
- Sinister Scythe: His kusarigama.
- Token Good Teammate: To Naraku, at first.
- Took a Level in Badass: Prior to his death, he was too scared to be an effective demon slayer. After being revived and controlled he loses this fear.
- The Undead: The only thing that keeps him "alive" is the Shikon shard on his back. When Naraku reclaims it, however, Kikyo's lingering light brings him back.
- Trauma-Induced Amnesia: He was so badly traumatised by his murder of the youkai hunters under Naraku's possession that he refuses to remember it. Naraku uses this to his advantage, as he does with everything; offering to use his powers to ensure that Kohaku can't remember anything about it, no matter how forcibly reminded, is why Kohaku agreed to serve him in the first place.
- Unwanted Revival
- Used to Be a Sweet Kid: And he still is... when not controlled.
- Youthful Freckles
Rin was a young orphan child who encounters Sesshomaru while he is recovering from being beaten by Inuyasha. In spite of Sesshomaru's coldness, she shows no fear of him and instead develops a case of hero worship. For his own reasons, Sesshomaru allows her to accompany him and Jaken thereafter.
Voiced by: Mamiko Noto (JP), Brenna O'Brien (EN), Mariana Ortiz (LA SP), Letizia Ciampa (IT)
- All of the Other Reindeer: The people in her village treated her like crap.
- Back from the Dead: Twice.
- Bird Run: Occasionally, including in at least one of the opening sequences.
- Cheerful Child: Despite having witnessed her family being murdered and being beaten to a pulp for stealing food, she manages to smile when Sesshoumaru asks what happened to her. She becomes much more playful once she starts traveling with Sesshoumaru.
- Cute Mute: In her first appearance. She gets over it after joining Sesshoumaru.
- Damsel in Distress: Is frequently the target of enemies seeking to exploit Sesshoumaru's fondness of her.
- Does Not Like Shoes: Constantly goes barefoot. Notable for being the only example that's not at least half-demon.
- Expy: Of Natsume
- Girlish Pigtails: Or better said, her single one.
- The Load: The number of times she does something usefull are totally dwarved by the number of times she needs to be rescued.
- Morality Pet: To Sesshoumaru, in an oddly inverted case of the dog petting human.
- Parental Abandonment: Her parents were killed in a bandit attack.
- Plucky Girl: Rin may not be much use in a fight, but let's face it, she's brave as hell. Heck, the first time she meets Sesshomauru she doesn't run screaming when he snarls at her but actually dumps water on him; and when Jaken's sick she climbs a mountain filled with youkai to find a cure for him, without a second thought.
- Satellite Character: She's largely defined by her interactions with Sesshomaru.
- Shipper on Deck: She becomes very excited when she thinks that Kagura might be in love with Sesshomaru, tries to convince Jaken that she's right, and says that they should trust Kagura more after she comes to this conclusion - seemingly trying to get them closer together.
- Third-Person Person: In the Japanese dub.
- Token Human: Of Sesshomaru's group until Kohaku starts traveling with them.
- Why Did It Have to Be Snakes?: At least in the anime, she's shown to be afraid of wolves. Justified in that some wolves killed her.
This goblin-like youkai is Sesshomaru's longsuffering and loyal retainer. He is not a very powerful fighter, but can wield the Staff of Two Heads in order to assist Sesshoumaru when needed.

- Battle Butler: To Sesshoumaru.
- The Chew Toy: Jaken's role in the series boils down quite effectively to "show up, highlight how annoying he is by being a jerk and/or kissing Sesshomaru's ass, then get abused by Sesshomaru for being such a lickspittle". Even Kagome, prior to awakening her powers, easily dumps him in a river and whacks him with his own staff for badmouthing InuYasha.
- Diagonal Cut: Kaijinbo kills him this way. He recovers, thanks to Tenseiga.
- Fantastic Racism: Jaken hates humans and half-demons, and routinely insults and mocks them. Then again, this might be a way of singing the praises of the similarly disdainful Sesshomaru, given his jeers often revolve around how worthless such beings are compared to him. His disdain for Rin comes from envy that a human girl they recently met gets far better treatment than he does.
- He Will Not Cry, So I Cry for Him: When Rin kicks it again, Jaken cries on Sesshomaru's behalf explaining that Sesshomaru would never do something so undignified himself. Jaken also sneezes for Sesshomaru when others are gossiping about him, since it would be too undignified for Sesshomaru to sneeze.
- I Owe You My Life: In the anime, this is his reason for following Sesshoumaru so loyally.
- Iron Butt Monkey: He receives a lot of physical abuse, mostly but Sesshomaru, but is still kicking.
- Jerk with a Heart of Gold: Toward Rin. He's initially quite sour about a human joining them (more so with Sesshoumaru showing far more compassion toward her despite his longer time of servitude), but is quite protective of her (though partly out of fear for Sesshoumaru should anything happen to her).
- Playing with Fire: His only attack is to fire gouts of flame from the ever-present Staff of Two Heads.
- Oh Crap!: Whenever Rin is endangered and he's unable to protect her, he panics thinking Sesshoumaru will kill him.
- Old Retainer: To Sesshoumaru.
- Red Eyes, Take Warning: In the manga; in the anime his eyes are yellow.
- Sycophantic Servant: Is Sesshoumaru's yes-man to the nth degree.
- Third-Person Person: He has been known to say "This Jaken" in the Japanese dub.
- Undying Loyalty: Despite being a real kiss-up, he's very loyal to his master despite his cowardice and being abused constantly.
- Youkai: Resembles a kappa, being a green-skinned goblin with a beak.
Kaede is Kikyo's younger sister and assistant. Following her loss of an eye and Kikyo's death, she became a miko herself, and is an old woman when Kagome arrives in the past and unseals Inuyasha. She recognizes Kagome as Kikyo's reincarnation, and assists Kagome and Inuyasha by providing advice and information.

- The Comically Serious
- Cool Old Lady
- Demoted to Extra
- Eyepatch of Power: A very spiffy metal one.
- Eye Scream: Lost her left eye as a little girl, some time before Kikyo's death. In the anime the culprit is Kikyo's old rival, the Evil Miko Tsubaki. In the manga, it's implied Inuyasha's attack was responsible.
- Force Field: Can make minor barriers and joins with Miroku to make one to protect InuYasha as he heals from his wound fighting Sesshomaru.
- Holy Hand Grenade
- Magical Gesture: Does the full blown Asian Rune Chant in The Movie.
- The Medic
- Mission Control: Her village often becomes the headquarters of Kagome and Inuyasha's team.
- Never Mess with Granny: Any old woman capable of more or less keeping up with all of this qualifies. Not many people can stand up to demons, and few will go headlong into fights against them.
- Ye Olde Butchered English: In the dub.

- Everything's Better with Cows: His perpetually dazed, three-eyed cow.
- Mr. Exposition
- Obfuscating Stupidity: The whole senility thing? He's playing dumb.

- Playing with Fire: Not only he can spit fire, but his hammer can create lava pits when used.
- Pointy Ears
- Really 700 Years Old
- Secret Keeper: He knew the truth about Tenseiga and Bakusaiga all along.

Kouga is the leader of a tribe of wolf youkai. He has collected several Shikon Jewel shards, which enable him to run incredibly fast and to execute powerful kicks. He kidnaps Kagome due to her ability to sense Jewel shards, and soon develops a crush on her, much to Inuyasha's annoyance.

- 24-Hour Armor
- Animal Motifs: Wolf.
- Back for the Finale: In the anime, he appears briefly during the epilogue.
- Does Not Like Shoes
- Easily Forgiven: The heroes aside from Inuyasha are quick to forgive that in his debut episodes he set his wolves to feast on a human village (and had done so in the past), kidnapped Kagome, declared he intended to make her his mate and would use her to get more jewel shards, and warned if Inuyasha interfered he'd kill him and feed him to his wolves.
- Expy: In theory Ryouga, but appearance and name only, as he is enormously nastier.
- Fantastic Racism: Constantly mocks and insults Inuyasha either because he's a half-demon or because his demon lineage is that of a dog, while Koga is a wolf demon.
- Handsome In Mink

- Hidden Depths: He's actually quite clever, and he values loyalty above all else.

- Lightning Bruiser: So fast he makes whirlwinds by running.
- Lima Syndrome: He kidnaps Kagome for her ability to see the Shikon jewel shards, but ends up falling in love with her because of her kindness and loyalty.
- Long Bus Trip: In the manga he's never seen again.
- Magic Skirt
- Mars Needs Women: Like most demon characters, he doesn't hold humans in high regard, treating them as nothing but a food source early in the series. However, this doesn't stop him from developing a crush on Kagome.
- Moral Myopia: His Establishing Character Moment is slaughtering an entire village because his pet wolves were hungry, but enters an Unstoppable Rage when his pack is killed by Inuyasha's group, even though the group only killed the pack out of self-defense. Despite this Koga is considered to be sympathetic.
- The Nose Knows
- The Only One Allowed to Defeat You: Insists that he alone will be able/allowed to defeat Naraku.
- Ornamental Weapon: His sword. He only uses it once to free himself from Moryomaru's assimilation abilities, and mentions that he took it from a human.

- The Rival: To Inuyasha.
- Super Speed: Helped by the Shikon shards in his legs.
- Super Strength: Helped by the Shikon shard in his arms.
- Tame His Anger
- Throwaway Country: A rare example of a "heroic" character actually being a cause of this trope. Koga slaughtered the populace of two villages, on screen, and not a word is ever said about them — or the others he may well have destroyed before he met Kagome.
- Wolverine Claws: His Ancestral Weapon the Goraishi. Ironic given his voice actor.
- Would Hit a Girl: "Hey Kagura! Wanna know how the Wolf Youkais deal with evil bitches?" *punch*
- Youkai: A wolf one

- Anime Hair: Both.
- Butt Monkey: Whenever they appear, they'll usually be tired and beg Kouga to slow down a bit, as they can't catch up with him.
- Calling Your Attacks: Parodied in a filler episode: they try to take on Sesshomaru and start yelling random names and threats as they pose. Good thing Sesshomaru was in a good mood.

- Boyish Short Hair
- Dull Surprise: She takes everything surrounding Inuyasha, Kagome, and the Feudal era in stride.
- Good Parents: She cares for Kagome very much and supports her as much as possible, probably thinking it's her destiny and since she cannot stop her, she'd better help her.
- In the Blood: Like Kagome, she finds Inuyasha's ears cute and tries to play with them when she first meets him, much to his annoyance.
- No Name Given: She's only ever referred to as "Mom," "Mama," "Mrs. Higurashi," or "Kagome's mom."
- Secret Keeper: She knows of Kagome's journeys in the feudal era and helps cover for her.
- Unfazed Everyman: "What's that Kagome? You say our well is a time portal and demons exist? Oh that's interesting. And you want to skip school to go through this portal to a place where demons try to kill you on a regular basis? Well sure, go right ahead. Don't worry about school, I'll provide a cover story."
- Widow Woman: Her husband aka Kagome and Souta's dad died in an accident, which is one of the reasons why she moved into her husband's family home aka the shrine. (The other is that Grandpa Higurashi's wife had also died, so the old man wouldn't be alone.)

A huge half-human, half-demon character who owns a field of healing herbs along with his old, human mother. Despite his large, intimidating appearance he's a gentle and shy creature.
- All of the Other Reindeer: He was frequently bullied by the other villagers, and instantly accused of attacking humans simply for being half-demon.
- Badass: When provoked into a fight, he can kill demons with his bare hands. In the anime he beheads a giant insect demon by hugging it, and then shatters its head with one punch.
- Beware the Nice Ones: Generally passive and kind, but as shown in his appearance, he's not one to be trifled with when push comes to shove.
- Covered with Scars: Due to being attacked and bullied by the villagers.

- Super Strength: Capable of tearing giant demons to pieces with his very hands. Luckily he's also very peaceful.
- Tempting Fate: Subverted; when Kagome is helping him tend to the herbs, he thinks about how it's the first time he talked to a girl without said girl screaming, only for Kagome to start screaming bloody murder a split-second later. As it turns out, she was freaking out over a worm.
- Top-Heavy Guy: His upper body is larger than his lower one.
- The Unreveal: In the anime, Rin meets Jinenji in his "full human" period, but we don't get to see how he looks like, as he's covered by a giant blanket.

- Half-Breed Discrimination
- Half-Human Hybrid
- Meaningful Name: Her name means "Purple Woven," befitting her purple eyes.

- You Killed My Father: When she discovers that Taigokumaru killed her father, she promptly expels him from the barrier, giving Inuyasha free rein to attack and kill him.

- Arm Cannon: Sort of: it was part of a demon who was trying to assimilate him, and can shoot demon-killing light (which is actually composed of lesser demons).
- Back from the Dead: Resurrected by Naraku, so that he could be merged in Moryomaru again.
- Identical Stranger: Since Moryomaru confirmed that Goryomaru already existed as a monk before he came into existence, this means that his similarity to Moryomaru is just a coincidence.

- Bunny-Ears Lawyer: Given how he behaves, he could be Totosai's brother.

- Overly Long Tongue: He has one, which he uses to test Hiraikotsu's recovery rate.
- Rubber Man: Has the ability to stretch his limbs to grab a jug from a long distance.
- Sink-or-Swim Mentor: The test he puts Sango through will either repair Hiraikotsu or destroy it forever; or even kill her.
The mother of Sesshomaru, whom he consults for advice on how to perfect the Meidō Zangetsuha.
- Almighty Mom: She achieves what almost no one else could ever do - putting Sesshomaru in his place in the most brutal manner possible.
- Big Fancy House: She possesses a huge, sprawling traditional Japanese palace. The location? Floating amongst the clouds. It takes even someone with Sesshoumaru's insanely good nose a good few days of active searching to actually find it and even then his mother has to come to meet him before he can locate it. The lady must be an absolute bitch to get in touch with at short notice.
- Jerk with a Heart of Gold: She proves that she truly does care for Sesshomaru by using the Meidō Stone to resurrect Rin.
- The Mourning After: She remains loyal to the Inu-no-Taisho years after his death.
- Parental Neglect: The Inu-no-Taisho explicitly told her not to be worried or concerned about Sesshomaru even if the test she puts him through endangers his life, and at best, she's only casually concerned about her son. Then again, it's not like he needs coddling.
- No Name Given/Unnamed Parent: As is the norm for the series.
- Strong Family Resemblance: Sesshomaru gets his Facial Markings from her.
- Youkai: Like her son and husband she is a powerful inugami.
Inuyasha's mother, she fell in love with a demon and gave birth to Inuyasha. She raised him alone in a village and was apparently from a noble family who had fallen into ruin. Sometime before the series, she died through unknown circumstances.

- Back from the Dead: According to the third movie, she died during childbirth and was revived with Tenseiga.
- Death by Childbirth: Subverted; though she does die in the process of giving birth to Inuyasha during the third movie, it's mostly due to Takemaru stabbing her with a spear. Thanks to Tenseiga, she gets better.
- Good Parents: She loved Inuyasha very much and tried her best to protect him.
- Impoverished Patrician: Implied to be one of these. In the anime she's shown living in a Big Fancy House alongside a very young Inuyasha, but said house is incredibly empty and no servants are seen around...
- Missing Mom
- Noodle Incident: It's unknown exactly when and how she passed; all Inuyasha says about it is that she died "a long time ago" and that "it wasn't her fault."
- No Name Given: In the anime and manga. Her name was made up for the third film like Inuyasha's father, but unlike his name, hers appears frequently since he's a big invoker of Say My Name.
- Posthumous Character: She's long dead by the time of the series.
- Rapunzel Hair: Her hair is long. Truth in Television, as she's a noblewoman and long hair was a status symbol and mark of femininity for women of the period.
- Raven Hair, Ivory Skin: She's black-haired, fair-skinned, and is explicitly described as a beauty by Myoga.
- Stepford Smiler: It's implied in some flashbacks she was this, trying to shield Inuyasha from the pain, humiliation and persecution she knew his heritage would earn him in the future. One of the few memories Inuyasha has of her is how he once asked her what a "half breed" was, and he noticed she was Trying Not to Cry...
Inuyasha and Sesshomaru's father, a great demon lord who was known throughout Japan. Though he died shortly after Inuyasha's birth according to the third film, his presence is felt throughout the series in the trials and weapons he leaves to his sons, and the legacy they (especially Sesshomaru) aspire to.While he never appeared in the anime or manga save for the corpse of his demon form, he appears in the prologue of the third film on the eve of his death.

- Action Dad: To Sesshomaru and Inuyasha. In the manga, Inuyasha has limited memories because his father died when he was young. The third film contradicts this by instead claiming he died when Inuyasha was born, leaving Inuyasha with no memories at all.
- Badass: Clearly and obviously one of the most powerful characters shown in the series. It took a dragon to kill him, and in the anime movies he hung on through mortal wounds to fight his way through a castle of soldiers and see Izayoi before he died.
- Badass Baritone: In both versions.
- Badass Cape: Has a parted fur pelt on his shoulders that flows past his feet; it becomes twin streaks of fur running down his back when he transforms.
- BFS: Tessaiga, of course, as well as So'unga.
- Canis Major: Gigantic. The transformed Sesshomaru is smaller than his head.
- Crazy-Prepared: He set all manner of trials and tests in place for his sons before he died, which contributed greatly to both of their Character Development.
- Dying Moment of Awesome: Sealing a dragon that breathes lightning, despite having taken fatal wounds (in the manga, at least). The third film takes this further by having him survive for a little bit longer so that he can easily battle his way through a castle of soldiers to reach Izayoi, despite the fatal wounds he's carrying.
- The Faceless: Even when he appears in the third film, his face is never shown clearly. There are occasional close-ups of parts of his face, but otherwise his face is obscured in shadows, or he's facing away from the viewer, or his head isn't in the frame, etc. However, momentary glimpses of him can be seen as he's running through the forest as Freeze Frame Bonuses.
- Jerk with a Heart of Gold: See Manipulative Bastard for more details.
- The Good King: While it's unknown if his title and standing came with any land or other perks, he was a noble and compassionate daiyoukai.
- Large Ham: While he's just as even-toned as Sesshomaru when speaking to him, he still manages to make every word dramatic and intense. Then he gets into battle and acts just as Hot-Blooded as Inuyasha. His sons have inherited these traits to varying degrees.
- Manipulative Bastard: A positive fatherly take on this trope. He's left trials in place for them with the interests of spurring Character Development for the better, but like a true parent his lessons aren't learned easy and come with harsh truths attached.
- No Name Given: The above name is just his title, "(The) Dog General". The third film attached the name "Touga" ("King Battle Fang") to him during development and on the soundtrack, but it's never in the finished film and was mostly made so the staff had a name to refer to him by.
- Older and Wiser: Those that knew him don't hesitate to let Sesshomaru and Inuyasha know that not only was he older and stronger, but he was wiser than they are. His scene with Sesshomaru in the third film adequately demonstrates this.
- Only Known by Their Nickname: To the fans.
- Parental Favoritism: Implied, but ultimately averted; the chip on Sesshoumaru's shoulder stems from the belief that he was The Unfavorite to Inuyasha, to the extent where he actually believes his father was grooming Inuyasha to kill him. The situation between the brothers is eventually resolved when it becomes clear that their father understood the vulnerabilities of being half-human and just how powerful Sesshoumaru would one day become. His real desire was for Sesshoumaru to become a source of support and guidance for Inuyasha.
- Posthumous Character: He's long dead before the story started, and it is very clear that if he was still alive, a lot of the current enemies, including the fully demonized Naraku would not stand a chance against him.
- Samurai Ponytail: The same silver hair as his sons, worn in this manner.
- Secret Test of Character: The main reason Inuyasha got Tessaiga and Sesshomaru got Tenseiga. Later it becomes apparent there was more to it than this, though.
- Sins of Our Fathers: He left behind a lot of enemies that Inuyasha and Sesshomaru inevitably have to clean up now that he's gone, often because it's mentioned that the two are honor-bound to finish his battle, or because said enemies seek them out.
- Strong Family Resemblance: From what we can see of him, he looks like Inuyasha when Inuyasha's Super-Powered Evil Side is in control (minus the eyes, of course, which remain golden for the Inu no Taishou). The jagged facial markings Inuyasha carries in his transformed state are clearly inherited from his father.
- Youkai: He was an immensely powerful inugami.
An extremely powerful miko and the creator of the Shikon Jewel.
- And I Must Scream: After she died in the process of creating the Shikon Jewel, her soul was imprisoned within the jewel and forced to battle with the spirits of the demons she took with her for centuries.
- Badass: What better proof of badassery than fighting off hordes of demons nonstop for seven days and seven nights solid?
- Bowdlerise: In the manga, her remains are mummified as opposed to crystallized.
- The Dreaded: She was pretty much demonkind's boogeyman during her lifetime.
- The Faceless: In the manga.
- Facial Markings: Has a star-shaped marking in the center of her forehead.
- Master Swordsman: In addition to her already impressive spiritual abilities, she has mastery over the sword.
- Miko: Quite a powerful one, at that.
- One-Woman Army: She was said to have the combined might of a hundred samurai.
- Posthumous Character: By the time of the series, she's been dead for centuries.
- Raven Hair, Ivory Skin
- Regret Eating Me: The youkai literally had her in his jaws when she took him down.
- Small Role, Big Impact: She's long dead by the time of the series' beginning and only appears in flashbacks, but her influence persists, since she was the creator of the Shikon Jewel.
- Taken for Granite: Her physical body remains in crystallized form in a cave near Sango's hometown.
- Taking You with Me: What she does to the merged demon, resulting in the birth of the Sacred Jewel.
- Unwitting Instigator of Doom: She's the creator of the Shikon Jewel, and the indirect cause of all the tragedy surrounding it.
The Twins and Baby
Miroku and Sango's three children, twin girls and a boy. They are introduced in the final chapter of the manga.
- Always Identical Twins: The twins are only differentiated by their respective pink and green kimonos.
- Last Episode, New Character: The final new characters introduced in the series.
- No Name Given: Their names are not mentioned.
- Strong Family Resemblance: The twins look exactly like Sango, while the boy more closely resembles Miroku.
