Giant sword, bladed armor
The Murakumo Unit (ムラクモユニット Murakumo Yunitto) is a weapon used by Kiiro Hikagami in BlazBlue: Bloodedge Experience - Part 2.
When activated, the Murakumo Unit takes the form of a set of armor that attaches itself to the user. It forms massive greaves to protect the legs and a large blade that is attached to the right arm's wrist. A visor is also included in the battle form of this weapon.
When not being used, Murakumo turns into a giant form behinds its user. Kiiro Hikagami is the only known wielder of this weapon and used it to kill Spinner Superior when he went insane and mutated from getting too close to the Boundary. While the weapon is strong, it cannot take on someone on the level of Clavis Alucard. When Kiiro uses the weapon, she summons multiple swords of light, but it's unknown if this is part of the weapon or if it is her Drive.
Murakumo comes from Ame-no-Murakumo-no-Tsurugi which is the original name of Kusanagi-no-Tsurugi. Literally, Murakumo means "gathering clouds."
