Like Father Like Son

Chapter One: New Moon

The sun had just set, casting darkness over the land as a red clad human male sat huddled in a small cave, back pressed firmly against the chilled rock walls. His breathing was slightly harsh, human senses on high alert as he knew these lands were occupied by demons. A shuddering breath left his pale rose pink lips as dark eyes scanned uselessly the woods around him. A loud snapping sound echoed in the darkness, made all the more menacing by the silent backdrop. Black clouds moving away to reveal hundreds of twinkling stars that cast dim light on the world below. With a tiny gasp the figure jumps as something moves in the distance, the trees shift and sway as an unquestionably powerful aura makes itself known. With a frightened whimper the crimson clothed male abandons his shelter to seek refuge else where, preferably far away from the looming heavy shadow of power behind him.

Almost four miles ran and the male collapses, his exhausted weakened body making a dull thud as it hits the slightly damp ground. Dark blue eyes look up into those of a young female, no older than perhaps seven or eight. The girl looks down at the raven beauty, her eyes sparkling with recognition as she gazes upon the lovely angel sculpted face. "Lord Inuyasha?" she asked, her head tilting in confusion as to why the silver haired inu-hanyo would appear as a human. For a moment she thinks she has made a mistake and shakes her small head only to see that it was indeed her Lord's younger brother.

"R-Rin?" Inuyasha asked softly, reaching out slowly to touch the girls cheek to make sure she was really there. Of course she had to be, if he were hallucinating Inuyasha would have certainly conjured up someone more familiar like the Miko Kikyo or someone else close to him. "Yes, it is I. But why are you like this? I mean, why are you human? Has some witch cast a dastardly spell upon you?" The young girl asked as she reached out to touch the tired males raven locks. "No I- I need someplace to hide. Just until morning." he told the other human, grasping her hand in desperation.

The young female child nodded, gripping Inuyasha's hand and pulling him slightly. With great effort the hanyo turned human forces himself to rise, limping slightly as he follows the girl to her campsite.

The second they enter the small clearing there is an obnoxious squawk from a small imp like creature, "Rin! What is this!? I send you for firewood and you bring back a human!? Why when Lord Sesshomaru gets back he's gonna-" Inuyasha cut the kappa off right there, "You sent a human child out to gather firewood in this forest?" he asked appalled, "You idiot! She could have been killed!"

"Hey! Who are you to raise your voice to me stupid human? When Lord Sessho-" Inuyasha scoffed before rolling his navy colored eyes, ignoring whatever else the imp had to say "I've got no clue why anyone would put up with you. Least of all Sesshomaru." he mumbles to himself before sitting down beside the fire, Rin coming to sit next to him. "Lord Sesshomaru will be back soon." She told Inuyasha happily as she handed him a cup of water. A sudden wave of nausea hit him. What would his brother do if he were to see Inuyasha in this state? He'd butcher the young hanyo most likely. He hoped he could perhaps distract or stall his brother long enough until his own demon powers returned and he'd be able to defend himself. Suddenly, as silently as a ghost the daiyokai himself appeared like an apparition across the clearing.

Sesshomaru had been making his way back to the campsite, he was in no hurry to have to listen to Jaken's obsessive babbling but knew he'd have to put up with if for the sake of looking after Rin. Ah-Un could only do so much and the Lord was positive he could not trust the kappa to look after his ward.

It was with a start that he noticed the scent of a human, one not belonging to Rin. He hastened his steps, only slowing down as he neared the clearing. He could see the figure perfectly even through the darkness, his view crystal clear as he stared at the person before him. For a moment he thought his eyes were betraying him for he could have sworn he was looking right at the Lady Izayoi. But that couldn't be, she had died many years ago and this being was obviously male, though his features and stature were rather delicate.

A single step closer and Sesshomaru was able to make out more from the human male, his shining raven hair and bright vivid navy blue eyes. His skin was glowing from the light of the fire and only seemed to make him that much more enticing. In this moment Sesshomaru understood just what his father had seen in that human mate of his, for now he saw the same in the being before him. Pure, untainted beauty. Innocence yet passion combined in a single form. Sesshomaru felt as if his heart had began to beat for the first time, and in all honesty it terrified him. The cold hearted Lord of the Western Lands was practically brought to his knees by a mere human, a simple mortal that he hadn't the slightest clue of their identity.

Did his father, the Great Dog General of the West, have this same fear as he had gazed upon the Lady Izayoi for the first time? The kind that gripped your chest, stole your breath and made your knees weak as that of a newborn babe. Making you feel as helpless as a pup. It was in that moment, that short elapse of time that threw Sesshomaru's entire world for a loop. Taking on the duty as Rin's protector, and for all other purposes her father, was one thing. But falling for a human, male or otherwise, was simply inconceivable and unthinkable. And utterly real, he could not say how or why, but at that moment he realized with great displeasure that the raven haired beauty before him had stolen his once frozen heart.

"Lord Sesshomaru!" Rin called out when she spotted the alabaster clad male enter the clearing. She stood, running over to him before stopping in front of her lord and bowing. "I'm so glad you are back!" Sesshomaru gave a slight nod of his head, showing Rin that he accepted her welcome before raising the unavoidable question. "Who is this human?" he questioned the girl who looked up at him in confusion. "The man over there. Who is he?" Inuyasha flinched at the icey tone in his brother's voice. "Lord Sesshomaru… Don't you recognize him? That's-" the girl was cut off by the red clad raven, "My name is Shingetsu. I beg your pardon Lord but it seems that I have gotten lost in these woods and came across the young girl." Inuyasha said softly, hoping Rin would catch on to where he was going with this and play along. Thankfully Rin was a very smart girl.

"Yes Lord Sesshomaru, he was lying on the ground and I was very worried. I didn't want to leave him all alone out in the woods so I brought him back here. I hope that is okay…" she trailed off, turning to Inuyasha and giving him a small smile. He returned it slightly but kept his head down, hoping against hope that Sesshomaru would not recognize him.

The Lord of the West seemed to consider this for a moment before letting out a small wisp of air, that for him passed as a sigh, "Shingetsu you said?" Sesshomaru questioned harshly already knowing he was correct but simply wanting to test the name out for himself. It felt slightly nice, though misplaced somehow, as if it did not fit the man before him. At the ravens slightly nervous nod he continued, "Very well. You may camp here the night but not a moment longer." the Lord replied formally.

"Thank you so very much my Lord." Inuyasha/Shingetsu said breathily as he looked up from under his lashes at his brother. He was struck with a small tinge of confusion as he gazed upon the ivory flawless face, swearing for a moment he had seen a bit of pink dusting the others cheeks. The human/hanyo shook it off as a trick of the fire light before turning his back to his brother. Unconscious of the other males' golden stare.

Note: Shingetsu means New Moon.

That's it for the first chapter, chapter two is already written and will most likely be up next week if not sooner depending on the popularity of this story.
