Inuyasha

Biodata

Power Progression

Background / History

Inuyasha grew up between two communities that rejected half-demons. Humans treated him with fear and hostility, while demons hunted him. His mother, Izayoi, protected him despite enduring criticism from the nobles around her; after her death, he wandered alone. These experiences left him sensitive to prejudice and reluctant to trust anyone completely 22 31 50.

His relationship with Kikyo developed from sympathy between fellow outcasts into mutual support and love. Although he originally wanted the Shikon Jewel to make him a great demon, he agreed to become human for her. Naraku exploited their incomplete trust by disguising himself as Kikyo, attacking Inuyasha, and provoking him into stealing the jewel 31 33.

Kikyo subsequently sealed him to the Sacred Tree rather than killing him. He remained sealed for fifty years until a companion broke the seal. Li Xia later pointed out that Kikyo’s choice of a Sealing Arrow over a Sacred Arrow contradicted the idea that she had simply wanted him dead, prompting Inuyasha to recognize that someone had manipulated them both 26 28 31.

Appearance

Inuyasha is a silver-haired youth with small dog ears, sharp claws, and a red Fire-Rat Robe. During his new-moon transformation, his claws disappear, his silver hair loses its luster, and his dog ears shrink as he becomes human 11 25 50.

• Dog ears: Immediately reveal his nonhuman ancestry and provoke Ogi’s initial hostility 23.
• Sharp claws: Vanish as his demonic blood becomes dormant 25.
• Fire-Rat Robe: A childhood inheritance that adjusts to his size 37.
• Tessaiga at his waist: Normally carried as a battered, rusty sword before transformation 24.

Personality

Inuyasha is candid, courageous, and quick-tempered. His blunt remarks frequently cause arguments with Kagome, and his habit of speaking before thinking becomes particularly dangerous when he tells the resurrected Kikyo to return her soul to Kagome. He means to help Kagome, but Kikyo interprets his words as a demand that she disappear 13 32 40.

His apparent indifference to other people’s opinions conceals a deep sensitivity to rejection. Li Xia’s acceptance of half-demons genuinely delights him, though he initially keeps that happiness to himself. Later, sincere praise of his strength draws an openly cheerful response 22 37.

Despite his rough manner, he protects others instinctively. He shields Kagome during the ghost incident, catches Ogi before she hits the ground, and stands between his companions and the Spiderhead leader. He also thanks Li Xia for saving his life and repays his help by recovering the Thunderstrike Blade 11 23 24 34 37.

His ambition to become a great demon is tied to strength, independence, and freedom from mistreatment. He insists that the Shikon Jewel will not corrupt him even when Miroku warns that it might make him kill his companions 41.

Abilities & Skills

Half-Demon Physique

His inherited strength, speed, reflexes, and vitality allow him to fight opponents with greater Demon Power 22 49.

• Catches Ogi after she falls from a ten-meter cliff 23.
• Recognizes Li Xia’s rescue plan immediately and attacks as the Spiderhead leader releases its hostage 25.
• Lifts and handles a wine vat weighing at least five hundred kilograms with one hand; Li Xia cites a four-star arm-strength rating 49.
• Recovers from Kikyo’s severe attacks within days 37.
• Rating discrepancy: Li Xia cites two-star Demon Power earlier and two-and-a-half-star Demon Power later. No corresponding advancement is described 22 49.

Enhanced Senses

His hearing, eyesight, and sense of smell provide information his human companions cannot readily perceive 23 27.

• Overhears Li Xia’s quiet explanation of half-demon vulnerabilities 23.
• Spots Urasue moving beneath the moonlight when Kagome cannot see her 27.
• Detects tomb soil and familiar fresh blood on Urasue, prompting concern for Kaede’s village 27.

Tessaiga Wielding

Inuyasha supplies the Demon Power that changes Tessaiga from a rusty sword into its imposing combat form 24 25.

• Uses it to cut through spider silk, Spiderhead minions, and two of their leader’s arms 25.
• Previously cut the Thunderstrike Blade’s shaft in half 39.
• Initially treats it largely as a weapon for hacking and smashing, drawing Totosai’s criticism 39.
• Its advanced abilities were deliberately stripped away by the Dog General so that Inuyasha could learn to control it gradually 48.

Wind Scar

The Wind Scar exploits the rift created when two demonic winds collide. Cutting that rift with Tessaiga releases a destructive gale 47.

• Totosai describes it as capable of destroying a hundred demons in one strike 39.
• Kirara serves as Inuyasha’s training partner by releasing an opposing demonic aura 47.
• He has not mastered its basic wind force when the Medicine Elder examines him 49.

Bone-Eater’s Well Travel

Inuyasha can cross freely between the modern world and the Sengoku Era without relying on a Shikon Shard 5.

• Travels through modern Tokyo with Kagome while pursuing Mayu 11 13.
• Unlike him, Kagome requires the jewel’s power to use the well at this stage 5.

Weaknesses and Limits

• New-moon night: His demonic blood becomes dormant once a month, turning him into an ordinary human and preventing him from maintaining Tessaiga’s transformation 22 25.
• Poison vulnerability: The Spiderhead leader’s venom incapacitates him during his human transformation; Myōga removes it 25 26.
• Purifying spiritual power: Kikyo’s Sacred Arrow dispels Tessaiga’s transformation and nearly kills him despite his defensive equipment 32 33 34.
• No innate flight: He seeks a replacement Wind-Fire Wheel specifically to address his inability to fight effectively in the sky 39.
• Limited ghost expertise: He tells Kagome that he does not know how to deal with ghosts and leaves their resolution to her 11.

Equipment / Weapons / Items

• Tessaiga — Forged by Totosai from the Dog General’s fang and left to Inuyasha. Its concealed potential and deliberately restricted abilities make learning to wield it a continuing challenge 33 39 48 50.
• Tessaiga’s scabbard — Absorbs part of the spiritual lightning from Kikyo’s attack, contributing to his survival 32.
• Fire-Rat Robe — Left by his father at his birth. Resists ordinary weapons and fire, repairs itself, and changes size to fit him. Kikyo’s spiritual attacks nevertheless tear through it 32 34 37.
• Single Wind-Fire Wheel — Recovered from the Thunder Beast Brothers. Its partner was destroyed by Kagome’s Sacred Arrow; Totosai declines to recreate it because it is a flying artifact rather than a blade 39.
• Enhancement Talismans — Supplied by Li Xia during the Spiderhead incident. Their magical enhancement later helps him react quickly enough to seize Kikyo’s pursuing arrow 33.

Relationships

• Kagome Higurashi — Traveling companion and Shikon Shard collector. Their frequent arguments coexist with his concern for her safety. Li Xia’s intervention in the Spiderhead incident prevents the intimate near-death experience that would have advanced their romance in the original timeline 11 26 27.
• Li Xia — Trusted companion whose lack of prejudice wins his goodwill. Saves him during the Spiderhead and Kikyo incidents, helps him understand the old betrayal, and encourages him to develop Tessaiga’s potential 22 25 28 34 48.
• Kikyo — Former lover. Their relationship was destroyed by Naraku’s deception; her resurrection renews both his attachment and her resentment. After nearly dying at her hands, he questions whether their love arose from genuine affection or shared suffering 31 33 34.
• Izayoi — Mother and the only person he trusted completely during his early life. Protected him from social hostility 31 50.
• Dog General — Father and the model for his ambition to become a great demon. Encounters his lingering soul during the immortal-wine trial, then punches him while recalling the hardships of his childhood 41 50.
• Sesshomaru — Elder brother who threatens him and covets Tessaiga. Inuyasha agrees to Li Xia’s proposal offering a six-month loan of the sword in exchange for thirty Shikon Shards and a gemstone leading to the Demon Graveyard 40 50.
• Myōga — Retainer who calls him “Young Master.” Removes his poison, explains his father’s arrangements, and introduces him to useful contacts 26 39 48 49.
• Totosai — Tessaiga’s creator. Repairs the sword and bluntly criticizes Inuyasha’s maintenance and lack of technical understanding 39.
• Miroku — Monk companion whose Wind Tunnel helps defeat the painter’s demon army. Challenges Inuyasha’s confidence that a Shikon Jewel wish would leave his mind intact 37 41.
• Kirara — Companion and Wind Scar training partner; also transports him to Totosai and the Medicine Elder 47 48.
• Naraku — Enemy responsible for manipulating him and Kikyo into turning against one another 28 31.
