Ichigo was a normal kid, he fared well in school, had a handful of friends, lived happily with his mother and twin sisters... but was also able to see ghosts. And a fateful encounter with a special group of, as he says, insane spirits, all of which are looking for someone from their past, turns his life upside-down. The moment he decides to join them, suspecting his father's disappearance is somehow linked to them, is the moment he stops being a normal kid.
