This is my first fanfic. It's pretty bad and only gets good from the 160th chapter. I hope you have fun reading! Synopsis. Truck-kun works again to send another soul to the Isekai post office to be sent to the Naruto world but our MC feels something strange and finds out there's someone else here with him! A/N : This book will be put on hiatus going forth since I want to rewrite the book due to improving over time while writing this book. A/N: The MC is a researcher at heart and wants to explore the world of Naruto with his own knowledge combined with what is possible in Naruto. There will be quite a bit of fan fiction behind the theory of the jutsus. Part one deals exclusively with setting up the relationships between the characters and reads more like a slice of life story, while part two will deal with the enemy of the novel and is more action and planning oriented. THINGS TO NOTE THAT PEOPLE COMMONLY DON'T LIKE! -MC shared body with Sakura for a few chapters. -MC 'reveals' his past life to one other person. (Nothing really negative happens because of it, though. I think so.) -Things in the first part are too 'reasearchy'? Too much depth in jutsus. -No Shadow Clone Jutsu. None of the characters are mine, except the OC's. The images are generated using AI.
