BLADE×BULLET 金輪のソレイユ

Valkyrie, the ultimate divine spirit weapon. Anyone who obtains its power can overcome the military of an entire nation. Deep in the North lies the closed city of Eljudnir, upon which many girls gather with varying aspirations. The last person left standing would be able to obtain its power. The resurrected Yagi met a girl who called herself Hela, the goddess of underworld. She told him that he possessed the spirit of the malicious god Loki, and informed him that, together with the black valkyrie Reginleiv, he was to hunt down those who sought the powers of the valkyrie.
