Maria visits her sister in the hospital to meet her newborn nephew, but her plan takes an unusual twist when she notices a strange yet endearing boy who seems to be enchanted by the baby. Curiously, only Maria can perceive his presence, leaving her puzzled about whether he is a ghost or a demon. Further escalating her bewilderment, a second charismatic guy carrying a bouquet of roses becomes fixated on the baby too. As events unfold, Maria is flummoxed when the peculiar boy reappears at her house, manifesting out of her nephew's body. He urges Maria to shield the child, without conveying any reason, and also instructs her to meet Ichirou KOUZUKI. Could he be the same man from the hospital? Maria is impatient to learn why the infant is stirring such intense interest among these enigmatic characters.
