The Girl from the Well & The Suffering

Okiku is a restless spirit that has been wandering the earth. As her own life was stolen from her by a murderer, Okiku devotes her afterlife to finding and killing anyone that has taken the life of a child, as well as helping other ghosts find the eternal rest that she has continually been denied. It's an unhappy existence and one that seems like it will be forever unchanging until she meets Tark, a teenage boy whose body contains evil that's only barely contained by tattoos that cover his body.
