Essence In The Blood

Mitsue is just a normal teenager who had some abnormal experiences in his life. However, things got more abnormal when he and his family moved to Tokyo and met this strange girl who he had to sit next to during classes. Will these abnormalities turn out in a good way?? Who is this strange girl??

P.S: I used Yu & Asuramaru's pictures (although Asuramaru is a guy) from Owari no Seraph mostly because I pictured the main characters based mostly on their features.
