Soul Drop

A mysterious silver-haired man named Ameya helps a young boy, Norio, though no one else seems able to see him. Their story intersects with a locked-room murder and an unsettling threat left behind as the only clue. The note warns that within three days, someone will steal a value equal to the life of whoever is in the room. Isa and Senjō, inspectors working for Sircam Insurance, suspect a culprit known as Paper Cut. The identity of the enigmatic murderer remains unknown.
