I accidentally delete the RWBY Reaction book when I was about to publish it and it pisses me off to no end. And I've seen that there are only a few books reacting to FGO. Or maybe only one that is called Observe F/GO. And this is a practice for my future book. But yeah, I've been thinking about this idea so yeah... Note : -I don't own anything except my book -English isn't my first language -Bad grammar -Maybe OOC -Sorry about my low knowledge. The Nasuverse is one of the most complicated stuff I ever seen -This book is heavily inspired by "Observing Fate/Grand Order" by @Sherlock145 so you will see many resemblence
