Shuumatsu no Valkyrie - Kamigami no Apocalypse

Synopsis:

Twelve of the thirteen fighters scheduled to engage in Ragnarok are announced to the gods by Zeus, the supreme chairman of the Council of Valhalla. The voices of those who were not selected protest. Zeus, however, had anticipated this and promptly announces the launching of a new competition to choose the last position on the Ragnarok roster, breaking the taboo against gods fighting one another. The "Revelation" of the untold side of the Record of Ragnarok has begun!
