This all began a certain night when a storm was about to pass. In a basement where the ceiling loomed over its guests like a tombstone over its grave, a monster boy was born. His name is Adam.

A ghost claiming to be Adam’s friend comes to him: "Your heart shattered and its fragments got scattered about. Let’s collect them together." Led by the ghost, he goes out to the city night after night in search of the pieces of his heart. Meeting people, unveiling mysteries, recovering his heart...

One day, the secret of his birth shall be revealed.
