In two very different worlds two tremendous battles took place. One was in a world of ninjas fought by two twelve year old boys with incredible power at the Final Valley. The other was fought by Soul Reapers the Gods of Death at Soukyoku Hill. In the final moments each of the participants clashed and let out tremendous energy. It distorted the space between the worlds and unknowingly brought them together. When Madara and Aizen finally moved forward with their plans they discovered what had happened as well as everyone else. The united ninja and Soul Reaper forces defeated Aizen and Madara for good. However the worlds will never be the same as Soul Society is now linked with the Ninja world. 500 years have passed and now a new foe has appeared with both Aizen and Madara's goals. His name is Daichi Yakunan.

He was born a ninja of the Hidden Leaf village and excelled at all aspects of the ninja. By the time that he was born the Soul Reapers who could be seen by the ninjas because of their chakra, but by no one else had made a pact with the 5 nations to form an academy where both races have been able to learn and master each others abilities. Only the strongest ninjas with exceptionally high chakra have been able to obtain bankai.

The ninja villages still maintain the 9 jinchuriki with all of the beasts returned to their respective countries. Daichi attempted to capture the nine tail jinchuriki and seal the beast in himself. He was stopped but managed to elude both the Soul Reapers and Ninja. That was 10 years ago. He has since started his own organization called Kurotaiyou. Recovering Madara's research Daichi has gained control of the Gedo Mado and intends to gather the beasts again. His next goal. The hogyouku. Can the Ninja and Soul Reapers stop him?

(This is subject to change and I am not trying to God mod this guy. I figured Aizen and Madara were the 'Gods' of their series and since this is a crossover well you know.)
