This ninja is a ninja of Naruto world, a serious ninja. He traveled through time and space to become a ninja of the same generation as the Sannin, living and fighting in the ninja world, leaving behind the protagonist's own legend. A very serious Naruto love story, nothing wrong. (Tsunade is the only female lead, and she must be Tsunade, wife to all the gentlemen and ladies readers! No forced conflict, awkward pretense and slap in the face.)
