Final Weapon
A garish gun lies all alone in a Scandinavian forest. Its model name is NKS1867/4TO. It used to be a shield made from divine iron before being newly minted into the form of a gun. It's the Valkyries' newest armament, given to them automatically when they transform into their new Assassin summer Spirit Origins.
At times, this gun has been called "the final weapon."
...The best trump cards are always saved until the very end.
