Kagome: Perception
Kagome does not really interfere much when the youngish daiyōkai – who is revealed to be Inuyasha's half-brother, Sesshōmaru-sama – comes to Inuyasha to try and find out where the resting place of his father is. Part of this is because – being trained as a miko from a young age – Kagome can almost see the anger, loneliness, and pain coalescing around the daiyōkai. The other part of it is because she is beyond irritated with Inuyasha's continuous slander of her person. Kagome is perfectly talented with a bow and arrows – the reason the Shikon got shattered was because she is used to far better quality weapons than what she was handed, which she remedies when she gets knocked back into her own time after meeting the hanyō.
Honestly, the only reason she even needs the idiot's help is because she can't actually manifest her weird pink ki unless she has been meditating. Her powers don't seem to work the same way that most spiritual ki does, and that weakens her. She can infuse her arrows but that is about it.
So she needs the jerk's help. Joy.
Once they are in the tomb, Inuyasha and Sesshōmaru-sama get into another argument, whilst Kagome studies the barrier around the Tessaiga. It is a unique barrier, and she figures out why Inuyasha is able to get past it – and unable to actually grab it – after a few moments of study. Sighing, she stands up, walks over, and pulls the sword out from its sheath. The daiyōkai and hanyō stare at her incredulously and she shrugs, her kimono moving with the shift in her body as she says, "What? The barrier was clearly meant to keep yōkai out but not ningen – it's likely that a ningen has to be the one to remove it. It probably doesn't hurt that I'm a miko, for all that I can barely use my ki."
She turns towards Inuyasha and sighs at him. "I will only give you Tessaiga if you swear not to attack your brother with it. He is hurting enough as it is, I'll not have you adding to that! Otherwise I'll just give it to Sesshōmaru-sama."
"Keh, what the fuck d'you mean by that, bit-"
"SIT Inuyasha!"
The hanyō is promptly buried in bones as the command forces him into the unstable ground beneath them. "I mean what I said. And I also mean that I'll bloody well continue sitting you every time you do not call me by my name! I am not "wench", "woman", or "bitch", damn it all! My name is Kagome! Ka-go-me! You know this by now!"
She sighs and turns around to see Sesshōmaru-sama staring at her as if she were a particularly intriguing puzzle. Well, for all she knows, she might be one to him. She knows that she doesn't act like ningen females in this time act, despite her manner of dress being appropriate, and she is a miko who can't actually use her ki very well, despite clearly having the training necessary to do so.
Sure enough, the daiyōkai deigns to address her, asking Kagome, "Why is it you are travelling with the hanyō when he treats you so distastefully, miko?"
She takes in a deep breath and explains what she knows to him, starting with how she was raised as a miko of the shrine she lives on, her inability to call her ki to the fore, and the resultant mess that had come of Mistress Centipede's attack on her, not leaving out Inuyasha's lust for the Shikon or her new duty to gather the shards. "So he is aiding me in my quest now. Not that I'll let him have the Shikon, but I do need to wish the nasty thing out of existence since it has been pulled from me."
"Hn."
Then he speaks again. "This one will come for the Tessaiga in the future, miko. Also, the reason that you cannot pull out your ki is that it is more akin to yōki than to reiryoku. Yōkai channel their yōki through their bones, then muscles, then veins, then blood, and only then can it be accessed properly. This Sesshōmaru believes this information should be beneficial to you. It is a waste to see power unused."
Inuyasha is strangely silent as they exit the tomb – probably wary of getting sat again – and Sesshōmaru-sama leaves them to their own devices, retreating with his kappa servant. Kagome does not for one second believe that the reason Sesshōmaru-sama would be visiting them again would be to honestly try and steal Tessaiga. That was an excuse. It was far more likely that he would be sating his curiosity about her and probing into her relationship with the Shikon, which he clearly despised.
Sesshōmaru: Perception
The ornately dressed onna standing by his brother was a puzzle to Sesshōmaru. A puzzle, a cipher, an enigma. She was clearly far above the hanyō, a strange sort of miko whose ki was untrained and far more akin to yōki than to reiryoku, and had some sort of… power over him. What kind of power she had was adeptly demonstrated when she subjugated him into the bones making up the floor of his honoured father's tomb when the impertinent hanyō had the temerity to begin calling her a bitch. His half-brother's insistence on treating females as ningen did was one of a dozen reasons that Sesshōmaru despised his younger brother. Yōkai did not treat females with anything excepting respect and devotion and the utmost care – even stupid ones. Even females they found distasteful were ignored, rather than abused. This miko travelling with the hanyō was clearly intelligent, and had a force of personality much like a yōkai had. Determined, volatile, and empathic. He had not missed that beneath words he would usually have lopped someone else's head off for saying, there had been genuine understanding. It had spared her life, and the story she told him only further heightened his curiosity.
Born with the Shikon inside of her, shattering the jewel due not to inexperience, but due to an unworthy weapon. Being on a journey to collect said shards so she could finally rid the world of that vile thing. Sesshōmaru was beyond intrigued. He would seek his brother out, yes – but not for the Tessaiga. It would be to learn more about this intriguing miko of his.
A/N: Welcome to one of my two current in-progress fics. I'm continuing to break with tradition and posting this even though it is incomplete. I will continue updating on Saturdays, but I thought I would be nice and give the first update today. This is probably going to be a relatively short fic, with short chapters (averaging about 1k words, some a little shorter and some a little longer. Tenses will switch depending on what the characters demand of me. I hope you enjoy this: As a warning Sesshōmaru is fairly OOC (to an extent) however THIS IS EXPLAINED IN CHAPTER THREE. (Not to mention I always use the manga portrayal of Sesshōmaru, and in the manga he was far more emotional to begin with, even if his emotions were all negative.)
