What is so strange about beings that don't naturally exist in the world? Imagine you are making your way along an isolated street in the city of Tokyo, clear but solitary. You take a stroll through this street, touching them, but you still do not see them. Perhaps you are walking alone through a deserted alleyway in some remote village. You might walk right pass them and never notice. They are not ordinary. They can move as silently as ghost, as they are one...unseen by the human eye. And when they do appear, they strike fast. It could possess your body for all we know, and yet never see who or what did it to you. But we would not overlook this. Because we cannot ignore it for it is our job solve these events and we are a group of teenagers not ordinary unlike others. Ah, I see you blink with surprise. Teenagers? You are thinking. Surely teenagers cannot deal with ghost? But you are wrong. My friends and I are one of a kind and are very unique. Together we are known throughout our school by treading the path of as a spirit detective, a path full of hardship and danger. It is strange to think that we once knew little of these events could happen but truth was told when I came to this country of Japan along with my mum. But now I decided that I will join my comrades with their duty but them and I all have something different.
