So after some careful thinking I've decided I'm going to rewrite the entire story, sorry about not updating and giving an answer, but other things like work have been taking my time. After attempting to write the next chapter, and failing to get motivation, it made me realize that it wasn't going to work out because of the amount of mistakes I've been aware of, and new ones that some of you have pointed out.
It's probably going to take a while, but I'm gonna write the rewrite later on, and take a break to gather better information of the Nasuverse so that I won't make any more mistakes. I also won't pretty much copy the original source material so that it isn't some generic time travel harem fanfic.
Thank you all for being so understanding.
I'll see you guys later.
