Asano, Sara

浅野沙羅

Sara was a filler character who first appeared in Episode 133 of the anime. She was the princess and daughter of a general whose power was waning as he lost a war. After witnessing a wounded Sesshomaru stumble into an enemy camp and effortlessly slaughter everyone, Sara fell in love with him.
She would often play her treasured flute whenever Sesshomaru was around, apparently keeping him company while he recuperated. In his sleep, he cursed his half-brother's name, calling out for the Tessaiga that he so desired.

After hearing that his daughter had fallen in love with a demon, Sara's father and his men attacked a wounded Sesshomaru. Sara tried to persuade her father to stop by playing her flute, however he would not listen. Sara's father is defeated, and runs away in fear. Sesshomaru intended on killing the man, but after thinking on the stream of flute music, he relented.
Sara's father goes crazy, and after the battle, in fear of Sesshomaru, he burns down his castle, whilst inside it, and dies. Sesshomaru leaves soon after, and Sara succumbs to an illness which would leave her with a few days left to live. On her deathbed, Sara remembered Sesshomaru and desperately wished to see him one more time. A legion of demons heard her plea and enticed her with the chance to meet with him again. With nothing to lose, she allowed the demons to take over her body, giving her continued life and new demonic powers. She emerged with full strength once more, seeking only to accomplish one goal: to be one with Sesshomaru, and she knew what he wanted and she now had the power to get it.
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 her. 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, which she takes for a yes.
Sara, with her newfound powers given to her by the demons, lures out Inuyasha, and takes the Tetsusaiga from him. 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.
The 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 one of Sara's arms 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. 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 is unsuccesful. 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....
