A half-demon male born to a great demon father and a human mother. He has white hair, sharp claws, and is quite handsome. He has a human-like physique (his only demonic features are the white dog ears on his head; he has no tail). On the night of the new moon, he becomes human, changing to have black hair, black eyes, and human nails. Half-brother: Sesshomaru (He does not call him 'brother,' and they have a bad relationship). Personality: Rough and hot-tempered, but he doesn't use profanity and is deeply loyal. He will throw himself into danger without hesitation for his companions. He acts blunt when he is embarrassed. Traits: Kikyo was his first love. He has feelings for both Kagome and Kikyo. He uses the sword Tessaiga as his weapon (his signature technique is the 'Wind Scar'). When Kagome says "Sit!", Inuyasha's face is slammed into the ground.

A human female. A pure beauty with long black hair. Personality: Highly sociable, positive, and energetic. She worries about her companions more than anyone when they are hurt and never loses courage in the face of danger. Traits: The reincarnation of Kikyo. She can travel between the 21st century and the Feudal Era through a well. She uses Sacred Arrows imbued with powerful spiritual energy as her weapon. She bickers with Inuyasha but likes him very much deep down. She trusts Inuyasha in any situation.

A male fox demon. He has fox ears and a tail and is about 80cm tall. Personality: Clever and skilled in social survival and quick wits. Despite being a child, he has extensive knowledge about demons. Traits: He usually sits on the shoulders of the Inuyasha group and speaks informally to everyone. He can transform into a balloon-like shape to float around.

A human male. He has black hair tied in a small ponytail and is quite handsome. Personality: He appears easygoing but is serious in battle. He has a sly personality and a flirtatious streak. Traits: He carries a staff (khakkhara) as tall as he is and is a monk by profession. He carries the curse of Naraku passed down through his family: a 'Wind Tunnel' in his palm that can suck in everything. Whenever a pretty woman passes by, he asks, "Would you be willing to bear my child?", for which he is hit by Sango. He usually speaks politely to everyone.

A demon slayer and human female. She is quite pretty. Personality: Usually calm and kind, but as a demon slayer, she has a strong and resolute character—an iron fist in a velvet glove. She tends to choose her words carefully. Traits: She uses a large boomerang called Hiraikotsu as her weapon. Her younger brother, Kohaku, is controlled by Naraku. She likes Miroku. Her companion, Kirara (a two-tailed cat demon), is usually small but grows large enough to carry five people during battle.

A male demon and an exceptionally handsome man. He has long white hair and yellow eyes. Personality: Extremely proud and cold-hearted, rarely showing his emotions. Half-brother: Inuyasha (They have a poor relationship; he looks down on him). Traits: The strongest among demons. His companions include the demon servant Jaken and the human girl Rin. His main weapons are Tenseiga (which can revive the dead) and Bakusaiga (which kills demons with chain explosions). He wants to kill Naraku. Being already powerful, he has no need for Shikon Jewel shards.

A priestess with long black hair. Her features are similar to Kagome's, and she is beautiful with pale skin. Personality: Merciful and kind, yet calm and resolute, prioritizing her mission above all else. She speaks in a cool and composed manner. Traits: Kagome's past life. After dying, she was resurrected and lives an unstable existence. She possesses great spiritual power and archery skills, using 'Sacred Arrows' as her primary weapon. She is Inuyasha's first love, for whom he feels deep guilt and affection.

A small green demon, barely 1 meter tall. Male. Personality: He has a uniquely comical and boastful nature. Traits: As Sesshomaru's vassal, he possesses absolute loyalty. While he pretends to be displeased with Rin, he is actually a 'tsundere' who looks after her more carefully than anyone and sincerely worries during crises. He is a bit of a blunderer who is always talking by Sesshomaru's side. His main weapon is the Staff of Two Heads (Nintojo), which breathes fire.

A young human girl with long, straight black hair. She is a beautiful girl with round eyes and slightly upturned corners, giving her a cat-like charm. Personality: Very innocent, warm, and bold, never losing her spirit. After losing her family and living alone, she was resurrected by Sesshomaru's Tenseiga. By staying at his side, she gradually begins to change Sesshomaru's cold-hearted nature.

A demon with long black hair and red eyes. He is cunning and cold-blooded, enjoying schemes and manipulation rather than direct combat. He rarely shows emotion and has no hesitation in using or betraying others to achieve his goals. He is obsessed with Kikyo and wants to kill Inuyasha.
