Comprehensive Manga: Nishimiya Glass's Guardian Ninja

Indra Otsutsuki, the son of the Sage of Six Paths and the ancestor of the Uchiha clan. A person who relied on his own will to escape from reincarnation and became a being similar to a heroic spirit. In a world that I don't know, there are demons, monsters, and even gods who kill those who disobey. But tell me, you guy, who only knows a little bit about assassination and doesn't even know the three ninja skills, is called a ninja? Don't underestimate ninjas, you bastard. Looking at the world, Otsutsuki Indra felt the need to let these guys know how terrifying ninjas were. Of course, he had to get out of the body of this girl named Nishimiya Glass first.
