Review Detail of lunna in Fate/Oni

Well, I have early inspiration from that story to create this story. But there are some important and obvious differences especially in the last chapters which are completely different from that story.

I did said there are differences. Even the author of naruto the savior of holy grail did not mind if people are inspired to made story from his stories. he wrote it in his profile. but please made more differences, because so far, I cannot help but felt like i'm re-reading naruto the savior of holy grail. if you can do that, I will change my rating.
