Godou Kusanagi receives from his grandfather a stone grimoire, tasked with delivering it to an old friend residing in Italy. There, he finds himself immersed in a world of the supernatural. His path crosses with Erica Blandelli, a striking …

Godou awoke to an unforeseen presence beside him in bed, one who seemed destined for a prolonged stay.

Athena has journeyed to Japan in pursuit of Medusa, and with this quest, Godou will face his demise once more.

Godou would be forced to abandon his pacifism, compelled to meet the newly resurrected Athena with unrelenting force.

A quiet intimacy is blossoming between Yuri and Godou, a development that stirs a flicker of jealousy in Erica. However, such personal matters pale in comparison to the emergence of a new Campione within Japan's borders.

Godou has provoked a confrontation with Voban, one of the most ancient and formidable Campiones.

Voban has finally overtaken them, and Godou finds himself with no apparent recourse. In a scene witnessed by Erica, Mariya offers the ultimate sacrifice.

What began as a casual outing to the shore quickly escalates into a battle for Godou’s heart, a contest from which he can only flee with Athena’s aid. His difficulties, however, represent but the opening act of a far greater conflict.

Following his encounter with Perseus, Godou found respite at Liliana’s residence. Unable to contend with Perseus on equal terms, he was visited by Athena, who proposed an arrangement.

Godou stands no chance against Perseus without the necessary knowledge. He could ask Liliana for it, but that is not how he operates. How then will Godou overcome this legendary warrior of old?

A young woman has offered herself to serve alongside Godou, yet the Knights currently under his command harbor different intentions.

Erica's salvation hinges on a complete surrender; she must offer herself—entirely, spirit and flesh—to Godou.

Godou faces Metis, the serpent goddess of death and shadows. Her sole purpose is the annihilation of all things.
