There was a small town near the Abyss Train's path and a kid always play alone in the town. He couldn't have friend and he always wanted to get a friend who can play with him.
As usual, the kid was playing alone and accidently saw many souls in the train. He thought among that many souls, there can be at least one soul that will play with him. So he road on the train to find his friend. Since he always runs and plays in the train with souls, other souls call him as Jr. Jack.
