Reincarnated Immortal Senpai

I got tired of waiting for more books to read, so I decided to write my own. This is basically my Reincarnation Plan for R.O.B., if I get the chance. This story involves Multiverse Traveling, but will mainly be in Naruto world. Sorry Truck-kun, but not this time. (This is definitely Wish-Fulfillment. Disclaimer: I don't own any characters who appear in this story, other than my MC. The artwork and characters belong to their respective owners. I don't earn anything from this story and it is written only as a Hobby.) {This is my first time writing and English may or may not be my first language.} [Warning, this book will involve topics of homosexuality, you have been warned ] Hope you enjoy!
