Mukuro Hoshimiya

The 10th Spirit. She has golden long hair and eyes. She was drifting in space, but her existence was discovered by DEM during an attack and retaliation in the "God's Eclipse Volume," making her known to the Ratatoskr side as well. She refers to herself as "Muku," a shortened version of her name. She had sealed her own heart with the power of an angel, so her emotions never changed.

Shido opened her heart with the power of the "Pseudo-Witch," imitating the "Master of Unlocking," and during this process, Shido's memories flowed into her, making her realize that Shido had a past similar to hers, and she began to call him "Master" and adore him. However, because she wanted Shido all to herself, she sealed away the memories of those around Shido. Later, after Shido's memories were sealed, her hair was cut by a reversed Tooka, causing her to rampage and seriously injure Shido, but she was on the verge of reversing when Shido's desperate persuasion and a kiss sealed her spiritual power.

Her provisional identification name is "Zodiac." Her spirit gear, adorned with constellations, is the female sage-type spirit gear "Divine Spirit Gear, Number Six (Eloah)." The manifesting angel is "Master of Unlocking (Michael)," shaped like a key. Her abilities include "Close (Segva)," which locks and seals functions on a target, "Open (Raatyb)," which creates holes in space, "Small Key (Tefetey)," which reduces things to palm-sized, "Release (Shifrule)," which transforms a tin staff into a halberd shape to draw out latent abilities, and "Unbind (Heres)," which dissolves spiritual power or molecular bonds by touch. With these, she has shut down functions of things like the "Bandersnatch" and battleships, stopping them from functioning, and created holes that serve as entrances and exits in space, directly bombarding Earth from space.
