Ninja World: I Started a Dimensional War

Traveling to the ninja world and becoming an ordinary civilian with no talent or background, and the Akatsuki company's nationwide dream plan will soon be implemented, how should you survive? Fortunately, I did. If you defeat the dimensional character Doflamingo, you will be rewarded Zanpakutō Sode Shirayuki, and Doflamingo will automatically transform into the summoned character of the host. "Hiss... This is a bit too open!" There is nothing I can do, even if I don't think about getting stronger. Summoning characters from other dimensions can raise an army of thousands of people. "Zanpakuto, Devil Fruit, Noble Phantasm... So many things, and so many summoned characters, is it enough to fight a war?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
