Naruto: Retired Savior

This book is also called: The savior who is about to retire randomly comes to a world and prepares to live an ordinary life anonymously. However, because he violated some of the rules of time travel, his strength is sent back to the mortal world. However, he finds that the world is extremely dangerous and he has to work hard to level up. At the same time, he becomes a savior again. Isn't it very long? Anyway, the introduction I wrote is rubbish T_T. Please read the text. The protagonist's full set of JOJO powers, ripples, stand-ins, etc. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
