Background / History

Inuyasha was sealed for fifty years after events surrounding Kikyo and the Jewel of Four Souls. Before the seal, he had promised Kikyo that he would become human so they could remain together, but later found himself unable to learn what had truly happened. Kaede ultimately accepted that he had not been responsible for the tragedy and allowed him to leave after he ran from the village in distress. 120 125

When Inuyasha first reappeared near Maple Leaf Village, he intended to take the Jewel of Four Souls. Yorii Tsugikuni's effortless killing of the Centipede Demoness, followed by Adai's overwhelming strength, convinced him not to act rashly. 121 123 129

He gradually became part of village life by helping rebuild the settlement, protecting the village from yokai, and secretly studying Yorii's sword instruction. His desire for the Jewel weakened after Kikyo's return and eventually disappeared entirely. 127 129 133 141 189

Appearance

Inuyasha is a silver-haired half-demon with distinctly canine traits. He wears a red Fire Rat Robe and carries himself with the speed and physical presence of a powerful yokai. 124

• Long silver hair, including two shorter temple strands that reach his chest. 124
• White dog ears, golden eyes, fangs, and sharp claws. 124
• Fiery red Fire Rat Robe over a white undershirt and red lantern pants. 124
• A black rope is slung across his shoulder. 124

Personality

Inuyasha is proud, combative, and easily provoked, particularly when others insult him or question his strength. He teased Adai for amusement, repeatedly challenged stronger opponents, and initially resisted the idea of recognizing Yorii as a master. 124 133 169

Despite his outwardly aloof behavior, he becomes deeply protective of the people around him. He watches strangers entering Kaede Village, calls the village's residents his friends when Sesshomaru disparages them, and defends Maple Leaf Village from an invading army without hesitation. 141 145 163

He dislikes owing others and initially feels uncomfortable with Yorii's kindness. Over time, however, he openly thanks Yorii for intervening against Sesshomaru and finds genuine satisfaction in Yorii's praise. 135 147 164

Abilities & Skills

Half-Demon Physiology

Inuyasha possesses superior physical strength, speed, durability, and demonic senses, though his half-demon nature also imposes a major weakness.

• His tough skin and Fire Rat Robe allowed him to endure repeated impacts from Adai without serious injury. 123
• He can move quickly enough to appear as a streak of red light. 122
• He loses his demonic powers and becomes an ordinary human during the new moon. 133
• His half-yokai body lets him train Breathing Techniques with little physical burden. 142

Breath of Qi

Inuyasha secretly copied Yorii Tsugikuni's teachings and rapidly mastered the Breath of Qi.

• Greatly improves his physical power, reaction speed, and resilience. 145 146
• Allows him to contend with Sesshomaru's demonic-energy whips rather than relying on demonic power alone. 145
• Can be combined with his demonic power and aura to enhance his full-body combat output. 163
• His progress is regarded by Yorii as the greatest among the students he has taught. 146

Tetsusaiga

Tetsusaiga is the sword Inuyasha inherited from his father and chose to wield in order to protect others rather than remain under Yorii's protection.

• Retrieved from his father's tomb after Myoga guided him to it. 149
• Its power, combined with Breath of Qi, at least doubled Inuyasha's strength. 160
• He learned the Wind Scar after further training. 171
• The weapon was later strengthened and became visibly larger and more powerful. 185

Combat

Inuyasha's fighting style emphasizes direct, high-speed assaults and close-range power.

• Defeated Wild Wolf Gan while investigating attacks on nearby villages. 149
• Crushed a human army's charge by transforming into a spinning humanoid tornado and killed its armored general. 163 164
• Fought Sesshomaru long enough to force him to take their battle seriously, though Sesshomaru's Azure Dragon Wave ultimately surpassed him. 145 146
• Continued fighting after Tetsusaiga was damaged during the yokai army's assault on Maple Leaf Village. 172

Equipment / Weapons / Items

• Tetsusaiga — Inherited sword obtained from his father's tomb; later strengthened. 149 185
• Fire Rat Robe — Demonic robe that protects him in battle; later recovered alongside Tetsusaiga's strengthening. 123 185
• Word Spirit Prayer Beads — Beads around his neck that Kaede can activate with the command “Sit.” 129
• Wooden barrier token — Grants passage through Yorii's anti-yokai barrier; Inuyasha later loses one, which Yorii suspects was stolen. 167

Relationships

• Yorii Tsugikuni — Initially a rival and obstacle to obtaining the Jewel of Four Souls; later becomes Inuyasha's unacknowledged teacher, protector, and someone whose approval he values. 129 133 147 164
• Kagome Higurashi — A companion whose resemblance to Kikyo initially confuses him; she worries for his safety and helps ease his agitation after his encounter with Kikyo. 124 140 146
• Grandmother Kaede — Kikyo's younger sister and a stern guardian figure. She recognizes Inuyasha's innocence but continues to discipline him through the Word Spirit Prayer Beads. 125 129
• Kikyo — His former beloved; he once promised to become human so they could be together. Her apparent return causes him considerable turmoil. 120 140 159
• Sesshomaru — His older half-brother from a different mother. Their hostile encounters drive Inuyasha to improve his strength and master Tetsusaiga. 144 145 171
• Adai — Yorii's mechanical guardian and Inuyasha's frequent sparring partner. Adai repeatedly defeats him, but these bouts support his rapid growth. 123 133 146
• Miroku — A fellow Society member and frequent bickering partner; they cooperate on missions despite constantly provoking each other. 159 164
• Sango — Fellow demon exterminator and ally who assists him in defending Maple Leaf Village; she also intervenes when he bullies Shippo. 171 173
• Shippo — A younger yokai companion whom Inuyasha frequently teases, though they take part in the Society together. 142 169 173

Story Role / Major Arcs

Return to Kaede Village

Inuyasha first observes Yorii's arrival and the Centipede Demoness attack while considering how to reclaim the Jewel of Four Souls. He withdraws after witnessing Yorii's strength, clashes repeatedly with Adai, and is eventually brought back into the village. 120 121 123 124

Joining the Demon Extermination Society

After helping defend Maple Leaf Village, Inuyasha begins secretly learning Yorii's kendo lessons. He masters the Breath of Qi, joins the Demon Extermination Society alongside Kagome, Sango, and Miroku, and starts protecting the village from threats rather than pursuing the Jewel. 127 133 142

Conflict with Sesshomaru

Sesshomaru's search for Tetsusaiga brings the brothers into direct conflict. Inuyasha uses Breath of Qi to fight far beyond his former limits, but Yorii must intervene against Sesshomaru's Azure Dragon Wave. The encounter motivates Inuyasha to obtain and master Tetsusaiga. 145 146 149

Defender of Maple Leaf Village

Inuyasha helps investigate yokai attacks and missing-person cases, defends Maple Leaf Village from a human army, and later faces the larger yokai assault alongside Sango and Miroku. His defense of the village earns Yorii's recognition. 149 163 164 172 173

Four Great Demon Nations Assault

During the Four Great Demon Nations' attack on Maple Leaf Village, Inuyasha fights beside Kikyo, Sango, and Miroku against the Young Master of the Leopard Cat Tribe. After beheading the enemy, he is struck aside by Sesshomaru as the battle escalates. 195 196
