Valkyrie of the End: The Villain's Redemption

The Divine Realm decides to unleash divine punishment on humanity. The Valkyrie Brunhilde wins humanity a chance to take part in Ragnarok.

Thirteen against thirteen: humans versus gods. If humanity wins, it will be allowed to endure for another thousand years.

But Shakyamuni insists that the human contestants must be villains.

So the Valkyrie transmigrates through the worlds of anime and manga, recruiting villains from across the ages.

And so, the Suicide Squad of the Multiverse is formed!
