Sara Asano

Sara was an anime-exclusive character first appearing in Episode 133 of the anime. She was a human princess whom was infatuated with Sesshomaru and planned to steal the Tetsusaiga from Inuyasha in order to win the dog demon's love.

Background
Sara was the princess and daughter of a waning general losing a war. Sesshomaru happened upon the army's enemy's camp and slaughtered them all, ignoring the injury his brother inflicted on him. Sara laid her eyes upon Sesshomaru whom was slaughtering their enemy with such grace and power. Struck by his graceful beauty, the princess fell in love with him. She would often play her treasured flute whenever he was around which apparently kept him company while he still recuperated. In his sleep, he cursed his half-brother's name, calling out for the Tessaiga that he so desired. Word reached Sara's father about his daughter's infatuation for the demon. Unwilling to allow her to fall in love with a demon, he waged an attack against the injured, but still capable warrior. She tries to talk him out of it but his stubbornness gets the best of him as he brushes off her pleas. Sara plays her flute, hoping to further persuade her father to not fight. He ignores anyway and orders his battalion to attack. The humans were no match for him as Sesshomaru flicks away the rifle fire with a mere flick of his light whip. Defeated, the warlord retreats in cowardice. His fear towards the demon progresses into insanity as he commits suicide, burning down his own castle with him inside. Sometime after, Sesshomaru left and Sara succumbed to an illness which would leave her with a few days left to live. On her deathbed, Sara remembers Sesshomaru and desperately wishes to see him one more time. A legion of demons hear her plea and entice her with the chance to meet with him again. With nothing to lose, she lets the demons take over her body, giving her life again and new demonic powers. She emerges with full strength once more, seeking only to accomplish one goal; to be one with Sesshomaru, and she knows what he wants and she has the power to get it.

Synopsis
Sara appears to Sesshomaru hours after her cremation in hopes that he would remember her. While he does recall the event that transpired, he does not acknowledge ever actually meeting him. Sara quickly proposes that she can get him what he wants most, hoping that it would be the only way for Sesshomaru to reciprocate those same feelings to her. Although he does not agree, he lets her to go about her business, taking it as a yes. She returns to the village to pose as a sacrifice named Umineko to a sea god in order to lure Inuyasha out. Miroku, being his perverted self, rushes to her aid without a second thought. Sango goes on to free Sara but both she and Miroku end up suddenly petrified in glossy stone. As Inuyasha and the rest onlook the sight, Sara claims it to be the powers of the demon at work because they had saved her. Inuyasha easily dispatches of the demon but it does not undo the damage done. At a loss, Sara plans to explain as the group head back to the village...only to find all of the villagers petrified. The only way for them to undo the curse was to head to the sea god's shrine and move the stone inside. Though Inuyasha has trouble at first, Umineko suggests moving the shrine using the Tessaiga to move it. It succeeds but as the rock turns, Shippo catches on to the ploy at hand. The shrine suddenly repels Inuyasha and begins to cave in, crushing Umineko in the process, but pulverizes in a glob of seawood, revealing her to be nothing more than a demon puppet. As Inuyasha and his friends escape the trap, they encounter Sara as she reveals herself with Tessaiga in hand. Suddenly, Sesshomaru makes an unexpected visit before them.

Inuyasha attacks Sesshomaru, thinking that he had planned this. The full demon casually repels his attack. Sara attempts to move in for the kill, but much to her dismay, Sesshomaru releases his brother and fires a thick spray of his poison mist at her. She manages to avoid it in time, but now utterly confused. Sesshomaru stated that even though his desire for the Tessaiga hasn't wavered, he will not accept the sword if he himself does not obtain it alone, let alone having it taken away and to him by a human. The dog demon leaves the scene elsewhere. Inuyasha attempts an attack on Sara but uses her pendant to petrify him. Kagome thinks quick and fires an arrow at the jewel, shattering it and undoing the petrification inflicted on Inuyasha. The half demon continues his attack but Sara repels him and flees the scene. The demon princess later finds Sesshomaru standing in front of the tree he rested on while he was recovering. The two reminiscence about that day they met. Suddenly, Sara's eyes glint with an evil aura. Sesshomaru senses this and quickly catches on to the plan at hand. Sara, dumbfounded, is at a loss for words. Inuyasha suddenly appears to continue his attack but Sesshomaru draws his sword to repel him. His younger brother clinches his injured shoulder and flings his Blades of Blood as one of the stray projectiles lops off an arm which is quickly replaced with a group of snake-like demons that constrict him. As Sara attempts to finish what she started, Sesshomaru stands in the way again and vivisects her. The cut causes an entire legion of demons to suddenly spew forth from her body as it undergoes a metamorphisis into an ogre demon, revealing 'her' true form. The demons reveal that they were simply using Sara's body as a medium to carry out their plan to ultimately devour Sesshomaru, attempting to use Sara's wish to steal the Tessaiga and draw out the powerful dog demon. Sara's spirit appears and seeks to be forgiven for her actions. Without hesitation, he attempts to cut the demon down but to no avail as the demons feed on raw hatred, which apparently empowers him. Kagome attempts to purify them with a sacred arrow but her attempt is foiled. Seeing no other way to deal with this threat, Sesshomaru takes a risk and grabs the Tessaiga and draws out its battle form despite the seal rejecting him and uses the Wind Scar to vanquish all of the demons at once.

Sara, now free of the demonic influence, her body begins to dissolve into ash, expressing her own genuine love to Sesshomaru and apologizes for what she had done before finally passing away with a warm smile on her face. Though seemingly apathetic, he approaches the remains of Sara and sticks her flute into the pile, leaving away with a simple passing comment: Go play your flute in the netherworld....
