When I died I didn't expect to wake up with dark beings of immeasurable power looming over me. I didn't expect to be given new life in a brand new world. Now, armed with a powerful system that makes me stronger after every fight, I might be the last thing standing between the multiverse and absolute annihilation.

This is a Naruto/Naruto Shippuden/Boruto fanfic. It is possible that the MC might venture into other worlds but that depends on how everything goes. By the way, this novel will feature a system but before you start rioting, this system will not feature any bloodlines or summonings or anything like that. It's gonna be from one particular series, and the series in itself is going to be weaker than naruto so don't expect an OP mc from the start. There's gonna be a lot of training too.

So where do we go after we die? There are a lot of theories on that matter Most people all over the world assume that the dead move on to the after life. The good people end up in heaven while the bad have to suffer in hell. Others assumed that you just wake up in paradise or something. She even remembered someone saying that maybe you get to watch over the lives of those you love. And others like the Hindus and Buddhists believe in reincarnation. They believed that someone who died with good karma they would be reborn into a good life. Those who did not have good karma end up with a bad life. Like any normal anime fan that had read a ton of reincarnation fan fiction of course the thought of being reincarnated into a cool anime world crossed her mind... ________________ You guys know how this thing goes. I could give ya more details, but that would just ruin the fun

...Authors note... Just rambling, feel free to skip... Started this novel testing a lot of things out. Only when I started nearing the end of the first book and went on to the next is when I think I found some footing on how this will be written. In short, while the first book had some questionable decisions (and there will most definitely be more to come), I think the process helped me gain a better understanding of how I want this story to go and how I can improve on my writing skills. Well enough of me rambling, as always, thanks to everyone that gave this novel a chance and those that continue sticking around despite my slow updates, see you all around!
