A basic weapon used by AKB0048 members.
Microsabers are regularly used as microphones in concerts. When there is danger, they can suddenly become lightsabers that shock and cut to defend against the opposition.
A microsaber looks like an ordinary microphone when not in saber mode. They are microphones with a slim blue body. When in saber mode, they develop into a lightsaber with an aqua and green spear.
