After seeing Konoha in ruins, ravaged by the Otsutsuki clan, and watching familiar faces die one after another, Orochimaru devoted himself to studying the “Karma” in order to defeat the Otsutsuki. At last, he successfully developed a Karma of his own, only to have the activated “Plow” transport him to the world of pirates. Here, he becomes the big brother of the three little ones. With the strongest technology in the shinobi world at his disposal, he obtains the Zoan-type Mythical Zoan Snake-Snake Fruit, Model: Yamata no Orochi, and becomes the strongest of the Shichibukai, protecting his younger brothers and helping them achieve their dreams!
In fact, it can be written as a time traveler with Orochimaru's template ability. Orochimaru's behavioral logic in this book is not at all like Konoha Orochimaru's character, but it is not ugly or too poisonous.
