Koi & Kirai

Growing up in the demon dimension within the Land of the Yin-Yang after the brutal war between ninjas and assassins, hatred fuels the heart of young Sapphire Takahashi as he's forced to grow up parentless and wondering if his twin brother, Eriko, is dead or alive. Having the burden of high expectations placed upon him, Sapphire follows the footsteps of his father and dedicates himself to becoming not only an elite ninja, but beyond what any Takahashi has ever done. But first he must ace the try-outs, become a ninja in training, and graduate from the Ying-Yang Academy.

Through this training he becomes part of team one, led by the best and hardest sensei in all the land, Tamotsu Muraki. Along with his best friend the risk taker Ryu Sasaki, his flirtatious and hyperactive friend Kioshi Ayachi, and smart and gentleman friend Takeshi Nakamaru; they become teammates with shy Hiromi Hayashi, boy crazy Hikaru Inoue, caring twin Sayuri Yoshida, tomboy twin Minori Yoshida, their over-protective-over Sayuri friend Mamoru Ito, and the infamous ex-assassin Amaya Oshiro.

But being the prime target of the dreaded Lord Hashimoto and his assassins, team one must be cautious with who they trust and who they befriend. But the road to even fully trusting each other may not be possible as Amaya, Minori, and Sayuri are the legendary demon dragons, immortal enemies to the legendary wolves, who are none other than Sapphire and Ryu. The journey of Sapphire becoming Lord, team one breaking the barriers of rivalry within themselves, facing many enemies, and encountering many types of demons; along with uncovering many secrets of the past and discovering who they are, what they will become, and what their purpose is for living won't be an easy one. Pain, loss, betrayal, and deceit will either corrupt team one or help them become stronger. As love and hate go against each other, they only lead up to one thing and one thing only, Death.
