Y/N L/N lives an entirely normal life, before one night, he goes to sleep and wakes up the next day to realize he's not at home anymore. It doesn't take him long to also realize something isn't right after he gets attacked by someone from a popular anime franchise! Y/N suddenly has to partake in the Holy Grail war even though not even a week has passed since he was transported somewhere! Will his average knowledge of the series get him through it, or will he perish?

I thought it would be cool to write this, so here ya go Y/N L/N, he was a knight who was fighting for the angels in the old wars between the devils and fallen angels. He was only human, so he had no powers, but his skill with a sword is enough for him to be a challenging opponent. He participates in what is rumoured to be the final battle in the war, and that peace would soon follow. Or at least, that is what he hoped...

Iku, was an orphan, but he didn't mind. He was always a smart kid, always thinking. He was a genius, and because of this nearly all school education was funded. All the way to highschool, until he was summoned along with his classmates.

Y/n was shy and innocent kitsune when Yasaka found him she asked her if she wanted to go with her Y/n said yes and Yasaka was so happy that he had his own son she decided to train and teach him to suppress his power to that of a human so nobody can detect his power about the supernatural so he can be ready when the time comes. He met ophis when he was training in the woods one time when they first met Y/n thought who is the little girl Staring at him funny things ophis knows the boy too well and thought he was cute Y/n was the first one To approach say hi to ophis staring emotionless at the boy she said hi too and that's how they met they Talked to each other whenever they have time. When he was older Yasaka decided to enroll him to an all girls school now co-ed school also known as Kuoh Academy and that's when he met a certain white haired girl with hazel-eyes and that girl name is Koneko Toujou and lets just say his life will turned upside down. (P.S the yandere in this is not the one on killing but close to it it just like possessive and obsessive toward him and I don't own anything besides my OC.)
