Seraph of the End
A mysterious virus kills ninety percent of humanity, and vampires rise from hiding to enslave the survivors, keeping them as blood livestock. Twelve-year-old Yuichiro Hyakuya and his best friend Mikaela Hyakuya, tired of giving blood in exchange for safety, plan an escape with the other orphans. When Yuichiro becomes the only one to break free, he joins the Moon Demon Company-a vampire-hunting unit of the Japanese Imperial Demon Army.
