An unruly Valkyrie on a flying tiger, a stern angel in love with the rules, and evil pounding at the gate… What could go wrong?

Riddled with survivor’s guilt after Ragnarök, Valka wanders the universe as a bounty hunter. But when hired by angels to recruit warriors for the final battle against evil, she welcomes a chance at redemption.

General Konrad Lagarde, First Mate of the angel ship Blue Phantom, strongly rejects Valka’s methods. A stickler for discipline, he also considers this fascinating woman hazardous to his sanity, as she could make him forget all the rules.

Evil from another universe has infiltrated a secret society of former dictators hungry for power. Having massacred all the angels in his former world, the evil one wants to do the same here. The angels of this universe face their greatest challenge yet… destroy the evil one and avenge their fallen brethren… or the bringer of darkness will enslave us all.
