Suikotsu (睡骨, すいこつ, "Sleep Skill") was a member of the Shichinintai. Like the others, he loved carnage and killing; however, unlike them, he had a split personality. This personality was that of a kind-hearted doctor, who may have been the original personality until a traumatic event caused the birth of his other, more bloodthirsty, personality.


Fifteen years before the series began, the Shichinintai took a job for a lord. They were soon betrayed by the lord due to the Shichinintai being considered too dangerous to exist. They fled into the mountains, but they were soon captured and executed. Suikotsu and the other Shichinintai members would then be revived when Naraku would give the leader Bankotsu seven Sacred Jewel shards.

During the storyEdit

Suikotsu was looking after orphans near Mount Hakurei. He was met by the priestess Kikyō. She could sense the jewel shard in his neck, but was puzzled by it because it was not corrupt. They were then approached by the Renkotsu, Jakotsu, and Ginkotsu. They came to pick up Suikotsu, but he did not remember them. Inuyasha and his friends then arrived to where the Shichinintai were. During the fight, Suikotsu became injured. This sight of his own blood caused him to have a psychotic break. His evil persona awoke, and he joined up with the other members of the Shichinintai. They soon joined up with Bankotsu. They attacked the castle of the lord that betrayed them. After they destroyed the castle, they were approached by Kōga. Inuyasha's group arrived shortly thereafter. Suikotsu fought against Miroku; professing his hatred towards monks and doctors. The Shichinintai made a retreat after ordered to by Naraku's saimyōshō. They met up with Kanna and Kohaku, and were given new orders to kill Sesshōmaru with the rest of Naraku's enemies. Bankotsu ordered Suikotsu and Jakotsu to kill Sesshōmaru.


Suikotsu died after a battle with Kikyō and Sesshōmaru, the latter of which decided to fight him after he kidnapped and threatened to kill Rin. After suffering a fatal attack, he asked Kikyō to remove his jewel shard from his neck so that he can die peacefully. Sadly, Jakotsu violently removes the shard instead. Suikotsu claims it is alright however as he is still allowed to die.


Suikotsu suffers from multiple personality disorder. He has two, definite split personalities. One a gentle, philanthropist doctor who looks after orphans, the other a psychopathic and sadistic thrill killer with a Wolverine-like appearance that earns him his spot in the Band of Seven. When his evil side takes hold, he seems to possess a dry sense of humor and an insatiable desire for blood, while when his good side is in control, he often hallucinates that he has blood on his hands.

Physical descriptionEdit

  • Good Suikotsu.
  • Evil Suikotsu.

Suikotsu appears as a tall young man with brown hair and pale skin. While Dr. Suikotsu is in control, he has his hair tied back in a ponytail and wears a traditional haori of a common villager.

Suikotsu's true appearance is very different from his good half, his facial expressions are described as being quite similar to that of a yōkai.

Powers & AbilitiesEdit

When he is good, Suikotsu is a skilled healer who can make several remedies with various herbs for various injuries. He is often compared to a saint.


Suikotsu's Tiger-Claws.

While his evil self is out, he has athletic attributes that rival those of Bankotsu, and strength that rivals Inuyasha. He wields a pair of Tiger-Claws. He also claims to be an expert of close-range combat.

Manga vs. AnimeEdit

  • In the anime, the circumstances surrounding Suikotsu's multiple personalities are revealed. Suikotsu starts out as a doctor, but seeing so much death and bloodshed due to war begins to affect him psychologically. He finally snaps when he kills a soldier out of self-defense. Knowing that he killed someone causes him to develop a new personality that enjoys killing others.


"That ridiculous, do-gooder physician, he's held me back for far too long."
"I won't let you go any further. I've decided that you're gonna fight me; to be honest, I can't stand doctors or monks!"
"What are you doing, foolish man? Why don't you do us both a favor and stop acting like a saint! The real you couldn't care less about saving people; deep inside you want to hurt people, to kill them, isn't that so?"
"Jakotsu... I can do it now, right? I can kill this little bitch?"
"You're wrong, lady Kikyō, I would likely do it all again if I were able to, I couldn't stop myself. The mere thought of it is unbearable. Please, I beg of you, lady Kikyō, remove the jewel shard; give me death and release my tormented soul."



Evil Suikotsu awakened.

Suikotsu Awakening

Evil Suikotsu's awakening for the first time.

  • Suikotsu's name comes from two kanji (睡, "Sui"; 骨, "Kotsu"), and is translated as "sleeping skill," possibly referring to his "sleeping" personality.
  • Suikotsu's Theme-Music from the InuYasha Official Soundtrack, Vol. 3 is entitled "The Two-Faced Suikotsu".
  • Suikotsu's characteristic resembles that in Dr. Jekyll and Mr. Hyde, as the good half is a doctor while the evil half is a mad killer.
  • His eyebrows also disappear when his evil personality surfaces.
  • The evil Suikotsu's "claws" and hairstyle look similar to Wolverine's from X-Men. He has even copied some of his more well-known poses, such as crossing his arms over his chest or spreading his arms apart.
  • The blades of his tiger-claws have constantly changed their size, from being the length of the glove/handle, to being three times as long. The angle of the blades are also inconsistent.
