Abel and Sr Esther are "guests" of Count Gyula at his mansion. Gyula admits that he is a vampire but he does not drink the blood of Terrans...

A meeting turns deadly for the terrorist group Fleurs du Mal. Abel accompanied by an android, Tres Iqus, are sent to investigate, but end up discovering a young girl who possesses a great power. Now it's up to Abel and Tres to determine what she is and why was she in the custody of Fleurs du Mal.

A routine flight on the airship "Tristian," turns into a nightmare when hi-jacked by a vampire, Aflred, who belongs to a radical vampire group known as Fleurs du Mal. After making a threat to the Vatican (by dropping the Tristian if his comrades were not released from Vatican custody), Alfred believes that things are going according to plan...until he meets Abel Nightroad, a traveling priest from the Vatican. Little does Alfred know that Abel is not like any ordinary priest.
