No real name for it in japanese considering it's more of a transformation jutsu for enma.
The staff itself is made of adamantine, you can call it "Adamantine Staff", "Lightning Staff", or "Enma Staff", whtvr. It's sharper than a sword and is indestructible, as it is in cage-form. It can turn into a cage
And keep in mind, THE STAFF IS A LIVING BEING THAT CAN MOVE AROUND ON ITS OWN. IF YOU'RE TRAPPED IN A GENJUTSU, IT CAN ALSO DE-TRANSFORM AND INJECT ITS CHAKRA INTO YOU. It can also turn into a giant monkey and maul people
