Start with a Zanpakuto and build the strongest Mist Village

The Third Ninja World War.
The evildoer Mizunotsuki Yoru from the Hidden Mist Village suddenly appeared, defeated the Golden Flash, killed Shunshin Shisui, overwhelmed the three ninjas, and defeated Konoha!
"In terms of status, I am the head of the Mizunotsuki clan and the head of the Kirigakure Anbu! In terms of merit and contribution, I led Kirigakure to defeat Konoha and gained countless resources and money! Third generation, I think you are getting old and confused. You actually passed the throne to Yagura instead of me?!"
