Red Angel Vol. 1 (manga)

From the streets of modern day New York and the hallways of a Japanese high school, to the confines of a British boys’school dormitory, Mika and her twin persona Eru have stalked and hunted. The two are vampires—creatures driven by their thirst for blood. A fateful encounter with the enigmatic Kinsei reveals a clue to a forgotten past. Mika remembers nothing, but Eru knows of a shared past with Kinsei. Are Mika and Eru merely creatures of darkness, or, like Kinsei, are they something more ancient and powerful?
