The Suzaku and Byakko clans have been fighting over territory for generations. Their leaders, Shiranui of the Suzaku and Aura of the Byakko, have dueled countless times, always ending in a draw.

A prophetic shrine maiden appears before Shiranui with shocking news about the future. To save the world, he must marry his sworn enemy?! And their child is destined to be a savior? "Do you know how men and women can have a child...?" But Aura, despite being an unparalleled beauty, is completely clueless about matters of love. During the day they are powerful warriors; at night, these two novices set out on a quest to conceive a child—with the fate of the world at stake! (Source: Kadokawa, translated)
