Armor (after transformation)
Lux Sanctus: Murakumo has the shape of a large sword that can transform into armor; it is actually the Murakumo Unit's "true form". Murakumo means "Gathering Clouds", derived from Ama no Murakumo no Tsurugi - Kusanagi no Tsurugi - the Sword of the Gathering Clouds of Heaven. So far, all Murakumo Units appear to be physical replicas of Saya.
