The Kings Converse
Voban tells Mariya that he intends to re-enact the ceremony that Doni had crashed 4 years ago as he's bored and wants something interesting to hunt. Amakasu asks Godou and Erica to rescue Mariya as only a Campione can stand up to or stop another Campione. Meeting Voban, Erica manipulates the conversation to get Voban eager to fight Godou, who (naively) is stubbornly trying to find a way to settle things without violence. The end result is that Voban will release Mariya, but will hunt Godou down and take her back after giving them 30 minutes to run. However, if they can last till sunrise he'll admit defeat. Thus begins the duel of Campiones.

Campione!
Some people suddenly find religion, but for 16-year-old Kusanagi GoDo, it's that REALLY old time religion that's found him! As the result of defeating the God of War in mortal combat, GoDo's stuck with the unwanted position of Campione!, or God Slayer, whose duty is to fight Herectical Gods whenever they try to muscle in on the local turf. Not only is this likely to make GoDo roadkill on the Highway to Heaven, it's also a job that comes with a lot of other problems. Like how to deal with the fact that his "enhanced status" is attracting a bevy of overly-worshippy female followers. After all, they're just there to aid him in his demi-godly duties, right? So why is it that their leader, the demonically manipulative sword-mistress Erica Brandelli, seems to have such a devilish interest in encouraging some VERY unorthodox activities?
