Disclaimer: I don't own InuYasha, nor do I pretend to own the characters, this fan fiction is my tribute to the show, and just my own little adaptation as to how possible it is, for both Inuyasha and Sesshoumaru to have a little brother, based on a theory of mine xD.

However I do own Tenparumaru P, my character and my story, so read and enjoy.

The Third Son: A Tale of Inu no Taishou's Legacy

"My Existence is no longer a mystery"- Tenparumaru, Proud Son and Brother to Brothers

Prologue: Origins of the Lost One

Preface: Roaming the lands ever alone, enriching one's life by simple wandering, one is not likely to go wrong in that line of mere exploration, a Daiyoukai roaming the Feudal Lands aimlessly in his life, simply looking for knowledge to roam for seeking knowledge while still humble of his own powers and prowess; two rare traits not often passed onto such, but earned they were. The tale of the unfolding events that will change the lives of two brothers, separated by blood of a human, potentially brought together by a third.

Time and time again it is proven how arrogance led to downfall of great daiyoukai of power, yet in this pup's past it was kindness and love for humans that led to the downfall of a parent he never knew. Hatred by humans was something he'd learned, as did he learn the frailty of the species he'd come to see as simply needy and fearful of what was stronger than they. The humans were a troubled people, but held some potential and by meeting Kagome he'd learned a lot and how the world changed. In many respects he could understand, but as he traveled on the distance, his mind carried one jeweled thought the memory of his past and how he came to be…

"Remember my son; you are the proud and the future of your father's legacy, when you go to where I have instructed you…it will be time for you to know your place, you will seek out your brother in time when you've finished learning here." These words spoken by the regal Lady no Taishou, who knelt to her son, long pooling kimono gown resting at her feet, there huddled around her son's Sashinuki Hakama, there a light smile on her face as she rubbed his shoulders.

At the age of 12 now her son had come a long way in his growth, slowly developing under her watchful eye in the confines of her palace, and training was something common to ensure the boy knew of his own abilities and powers. She found it strange that his poison had differed still on a slight level than her own and her son Sesshoumaru; none the less she ensured he could summon at will the deadly poison claws that she named "Awai Dokkasou (Light Poison Flower Claw)" for the bright shine the poison emitted upon release. She found that he held some differences though left him to explore that depth on his own.

Knowing that he'd be ridiculed by those whom passed him along the road, she continued preparation to make her son as best fit at his young age that he would be. The world would be a difficult place for him to enter, but he would step forth and prove his worth, prove his very ability to survive the dangers of the world with strength that he'd been born with. She found his lack of drive and motivation for conquest slightly maddening but ignored it, and simply taught him what knowledge he should know of humans, the fact they made war and attacked youkai of all kinds. When questions arose, they were ignored…simply her son was indeed born differently than Sesshoumaru.

She had doubts of her son's ability to survive, more doubting him as a true Taiyoukai, was he capable of protecting himself by killing others? Could he take a life and not feel remorse? She questioned these qualities in him, and patted his head, sending him off to do what he wished, she had more plans; things for the future that had surpassed even her son in importance.

"Mother seemed a little bothered today, she wasn't so happy with my growth today, though I have improved, she wants more and more, and I can't give it to her." the young inuyoukai sighed as he strummed his fingers through the small brook just within the reaches of his mother's palace, he just found himself wishing that he impressed her more; he'd often asked her questions about his father and received little to his credit.

The pup had showed her his mastery of transformation, he could change to his truest form with great ease, even to point it wouldn't cause him as much hell on aches or devouring his youryoku (youkai energy) too much. Also maintaining a large amount of his control during the state; while not uncommon it wasn't something that happened often, and his ability to use the Awai Dokkasou grew dramatically, it was a thing of beauty to his mother; yet his stride of improving just didn't fit her margin of impressiveness.

"What does she require..? I can't be as dashing as Sesshoumaru...such drive and ambition...I just don't have it. I guess I'll have to try at ingenuity then, I have to get somewhere, I can't let this be the ends meet for me. I suppose I can only improve, but it'll have to be with more practice." He said with a light sigh, though determined he still had some annoyance that his mother continued to compare him to his great brother...who was many times his own age, but still he aspired to be great in his own way.

The life of Tenparumaru, second son of Lady no Taishou and third son of Inu no Taishou was unfolding now, as the pup was barely of age by human standards to leave, yet he had very few years left with his mother. He'd matured quickly, learned everything his mother had taught him about being a Inuyoukai Lord and carrying himself the certain way, but his curiousities and his love of life itself would bring about him. His visions of humans being pathetic lower beings was all he knew, but not what he believed entirely. His interest in humans; the lesser beings would be what leads the Inuyoukai on a wild adventure of life.

(End Prologue)

Well here's the opener for the story, while I have only just started this adventure.
