This comic breaks into three reading aspects: (1) A Prose about the history of the Tarot and its relationship with Madame Xanadu, (2) The Madame Xanadu story "Dance for Two Demons" and (3) the back-up story "Falling Down To Heaven".
 

Dance for Two Demons:

In this story there are two random wanderers to enter "freely" into Madame Xanadu's home.  Both wanderers seems unrelated at first but it seems they represent two characters of the tarot as their vices possess them. The first is a male drug user named Joseph (Who will represent the Kind of Wands) and the other is a curious female (Who will represent the Queen of Cups) who finds a Grimoire of destructive power. Both wanderers "fall in love" and a strange power takes over them and it is up to Madame Xanadu to stop them.
 

Falling Down To Heaven:

This is a story about alien invasion.  This time it is Humans that are the invaders to a strange alien planet.  It is a story about the restrictive and self centered way of Humans.
