Naruto: the Amnesiac Eye Demon Otsutsuki Teira

A 1-meter-tall mysterious man fell into the world of Naruto and was rescued by 14-year-old Uchiha Sarana and brought back to his home. However, the man even forgot his name and lost his memory. In fact, he is the Eye Demon Otsutsuki Teira, the strongest member of the Otsutsuki clan, extremely bloodthirsty and loves fighting. But as the saying goes, when he invaded other universes, he encountered a strong opponent, who beat him to the point where he couldn't even remember who his mother was, and he couldn't display his original strength. He didn't even have the impression that he could transform. His strength was completely different from before. However, will those enemies who were defeated by him let him go? How is that possible! The earth was no longer peaceful. Sasuke and Naruto had no platform to perform and became supporting characters. So can our protagonist regain his glory?
