This Shadow☆Star transformation allows the Mode: Chain Scythe form to turn into a a long black sharp sickle-blade, with white ornante patterns on it with a handle attached for the wielder, accentuated with three short spikes. A long black chain, composed completely out of the Meister's Shadow.
The blade on the Chain of Blackness is long enough to be wielded as a sword. Due to its original form as a chain scythe, it is capable of being thrown towards the opponent in the form of a long-range attack. Since the chain originates from Meister's shadow, they can still control the trajectory of the blade, even if its thrown a great distance away. There is always a part the chain that encircles Black Star wherever he is, giving him protection from assaults from all sides.
