"A calamity will occur that twists even the laws of the world."
Kagetsu Yakumo is staying in the land of Kaga to prepare for the coming disaster.
However, his hometown, visited for the first time in a long while, is the very picture of peace, with time flowing gently.
But his slumber on this quiet night is short-lived, as a crimson moon suddenly begins to shine eerily in the night sky.
What that moon brought was a certain anomaly that affected the people of the town.

This is a prequel manga to the Cardfight!! Vanguard Divinez Parallactic Clash anime, detailing the exploits of Kagetsu Yakumo prior to the beginning of the anime.
