Godou Kusanagi is in Italy, he has no clue why, but his grandfather has sent him to deliver an ancient stone tablet to an acquaintance.
For Godou, this is quite an experience, especially because he has no clue of the Italian language, and he can’t figure out what is so great about an old stone. Anyway, in the middle of the street, Godou stares to the tablet.
Soon after, a good looking girl, Erika Blandelli, begins to shout something to him. Godou doesn’t understand a word, but it seems that Erika can understand and begins talking Japanese. She asks him to give her the stone and do it quickly.
Godou tells Erika that he has come from Japan to deliver it to her real owner, but Erika doesn’t care at all and threatens him with a dagger. At that moment, everything changes and something estrange begins to appear in the near street.
A magical creature begins to destroy everything around. Erika waits no more and jumps to stop the ‘Heretic God’, after all, she is a knight and it’s her duty to save the innocent from suffering.
Godou can’t understand what he is seeing but still begins to run after Erika to help her. Godou falls down and drops the stone tablet, he begins to look after it and a strange kid stands still holding it. He asks Godou if it belongs to him, and if he intends to save the witch that is fighting the crature.
Of course, Godou responds affirmative and asks the kid for the tablet. A little after, a white stallion appears and suddenly disappears into the air. Then, Godou runs to help Erika, and after a huge burst, the creature disappears.
Once calm down, Godou tells Erika the name of his grandfather’s friend. To Erika’s surprise, it is Lucretia Zola, one of the most powerful mages around and well known as the Witch of Sardinia.
Now, Erika takes Godou to Lucretia’s place. Right in the front door, a cat asks them why they are in the front of her door. Godou tells his story and Lucretia receives them.
Now, Godou has been able to fulfill his task, but for some reason Lucretia is amused with him. Godou tells her about the kid he saw during the fight with the Heretic God. At that moment, Lucretia decides the tablet belongs to no one but Godou.
That night, a god appears to fight Verethragna, who is no one else but the kid that Godou met before. Erika stands up between both gods to stop their fight; instead, they try to kill her.
Godou saves Erika and uses the power of the tablet to steal Verethragna’s most precious power. As the result of defeating the God of War in mortal combat, Godou is stuck with the unwanted position of Campione!, whose duty is to fight Herectical Gods whenever they try to muscle in on the local turf.
