Disclaimer: This is a fan fiction using characters from Owari no Seraph (Eng: Seraph of the End), all created and owned by Takaya Kagami and Yamato Yamamoto.

Author's Note: I'd like to point out that this is my first fanfic, so I want to ask for criticism. As you might have noticed English isn't my native language but I will try my best to write as best as I can and avoid most spelling mistakes. If I repeat a mistake feel free to make me aware of that. Well, that's it for now. Enjoy reading!

AU: I really like Owari no Seraph but I always asked myself what if Mika wouldn't have become a vampire and died as Yuu thought he did. So in this fanfic, I want to write a story where Yuu and his squad realize that they killed Mika by accident while they were trying to save Guren (Ep 10). I will also only take inspiration from the Anime since I didn't read the Manga and therefore don't know how the story will continue (but hey season 3 will come sooner or later.. lol). See how Yuu handles the loss of the last member from his old family, how will he change how will his relations with his friends change? Fanfic shows Power struggle, which Yuu is a part of, in the Japenese Imperial Demon Army.

Major Changes in this Story:

Yuu: He is stronger (don't worry there's a reason for this although only mediocre)He is smarter(idk I hate it when the Protagonist is an idealist that can't keep his mouth shut at least sometimes)He falls for a girl..yes Shinoa x Yuu the only ship that makes sense for me.

Shinoa: No real changes planned for her.

Kimizuiki: He falls for a lady...yes Idk how I'm going to write that since the telephone pole is unromantic as fuck but we'll see about that.

Mitsuba: She hasn't got a crush on Yuu but on Kimizuki and helps Yuu understand the power struggle and politics of the army.

Yoichi: I legit have no clue what to do with him ^^ Does someone actually care about him?(Oh boy triggered tones of people now, didn't I..)U can suggest some ideas if u want so I make something out him. Let's just say he's work in progress.

Note: I know this was the most boring thing to for me to write and u to read but next chapter will be more interesting, I promise.
