200 years ago before the warring states era, the Inuzuka Clan bore an heiress Koimi Inuzuka who bonded with a male ninken and the two happened upon a man who wielded no chakra to speak of until she gifted it to him by making him an Honorary Inuzuka.
His name was Ren and bonded with a female ninken, the Elders of the Inuzuka Clan were furious but every test they threw at the previously civilian man he passed, Ren did the new moon ritual from night to morning to night again and grew stronger each day.
While this happened Ren fell in love with Koimi, the woman who had gifted him this chance to become something great but when he asked for her hand, Koimi's Father refused, her mother on the other hand wanted to give him a chance.
But no opportunities presented itself to her to test Ren, the chance came months later surprisingly when Koimi was kidnapped, Ren did everything he could to find her and get her back but was starting to become hopeless that he would never see her again.
Until one night in his sleep he felt her soul reach out to his, calling to him and soon after Ren found where Koimi was being held and rescued her successfully with his bonded companion and upon their return both of Koimi's parents granted Ren permission to marry their daughter.
Giving to them two rings that passed emotions to one another, they were special rings that when a promise was made on them and merged with the others chakra they would never come off and allow the other to feel emotions.
Their lives went on they married and their ninken mated, but one day after years of life together Koimi the pretty pink haired green eyed Inuzuka Heiress and Ren the brunet, onyx eyed man and their ninken passed on, only to reincarnate every generation, to find love with each other yet again over and over.
This is a tale of their reincarnations 10 generations later, the two will face hardships and trials the likes of which had never been seen, they will find love and friendship and lead the Inuzuka Clan into an entirely new era.
