[Owari no Seraph AU: Mika x Yuu | Boy x Boy] Around the age of 6, Yuu had lost his best friend, Mikaela, during a kidnapping incident. Both of them were victims, but luckily for Yuu, he was able to escape. The bad thing was that Mikaela didn't. From that day on, Yuu swore to find the kidnappers, avenge Mikaela and protect other children. Unfortunately after 10 years of protecting children from kidnappers, Yuu stumbles upon an accident that caused him to be hospitalized for a week. How else was Yuu going to avenge Mika now?
