Hoshimiya, Mukuro

星宮六喰

Mukuro Hoshimiya (星宮六喰, Hoshimiya Mukuro) is the tenth Spirit to appear in the series and one of the strongest Spirits to date.
Mukuro made her debut in the series in volume 14, when DEM discovered her drifting in outer space. DEM approached her rudely, and she retaliated by sending the warships' debris across the globe.
In terms of power alone, she is the strongest spirit, as she is able to fight on par with Inverse Spirits.
So far, Mukuro's Angel, Michael, has shown the following abilities:
Segva - Lock [解（ヘレス)]: Decomposes spiritual power and the bonds holding molecules together. It was first used during her battle against Tohka to annihilate the Inverse Spirit's Astral Dress and the surrounding buildings.
In terms of speech, Mukuro speaks in an overly archaic style. She often speaks from a third-person perspective by referring to herself as "Muku" (むく).[放（シフルール)]: Unleashes the true potential of Michael by transforming it into a halberd-like weapon.
Jerez - Solution [開（ラータイブ)]: Allows Mukuro to open up holes in space that can be used to teleport herself, summon forth meteorites, and redirect incoming attacks.
Shifuru - Release [閉（セグヴァ)]: Seals away certain functions of the target. Mukuro first used this ability to shut down DEM's machines and Fraxinus' satellite Realizers. As seen from Shido's example with his copy of Haniel, she can also seal the abilities of other angels. It even works on sealing abstract concepts like emotions and memories. At full power, she claimed that it could be used to stop the Earth's rotation.
