Lucifer

is a Demon who once attempted to usurp the royal throne in the Demon World. She is currently with the young Spell Master, Shinobu Takamiya.

Appearance
Lucifer appears to be a small girl with large eyes and long hair but a very expressionless face.

Her eyes have a distinct ring encircling each pupil, vaguely similar to that of a hawk, and they also enhanced with Lucifer's long eyelashes. Her hair is light-colored and very long, flowing down her back in a wavy manner.

Lucifer dresses in the Gothic Lolita fashion. She wears a light-colored, long-sleeved dress with frilly lace outlining the ends of her sleeves. The center of her dress bears a light-colored stripe with thin borders that extends from the top of her dress down to the ends of the skirt; several dotted marks are patterned throughout the strip with small, hourglass-shaped ribbons covering the patches of cloth that are not marked. Near Lucifer's waist, the skirt of the dress is cut apart evenly, revealing three layers of frilly skirts on the underside of her main clothing piece, each marked by a dark strip running horizontally near the top, with additional lacy cloths over each layer. Over the topmost layer, near the spot where Lucifer's main dress splits into two parts, there is a delicate rose with leaves underneath and three ribbons sewn beneath that. Similarly, there is a large ribbon tied at the back of the dress near the same area. Lucifer wears a thin, frilled shawl over her shoulders that is held together by a light bow, placed beneath the collar of Lucifer's dress. A small jewel is sewn beneath the closed collar. Lucifer completes her outfit with light-colored shoes.

Personality
Lucifer is an extremely silent and indifferent girl, making her appear to be mute. However, she is described by Takamiya as being more cruel and heartless, which has yet to be proven false in any way, given how Lucifer mercilessly carved out Furuichi's heart with no show of hesitation or even remorse for her actions. This is further supported by the fact that Lucifer always has an expressionless, almost distant face in all situations.

History
Sometime in the past, Lucifer fought against the Demon Lord for possession of the royal throne, effectively pulling the Demon World into turmoil.

Lucifer eventually left for the Human World where she came to possess a young boy named Shinobu Takamiya.

Return to Ishiyama High School Arc
In the midst of Takamiya's fight with Oga, Lucifer reveals her presence as she sits upon Takamiya's right shoulder. She uses her abilities to help him launch an attack on Oga and remains on standby afterwards. However, she somehow disappears following a series of explosions caused by Oga.

Lucifer then returns and stabs through Furuichi's chest with her bare hand, pulling out his "soul" cleanly from his body. She looks at him callously before returning to her spot beside Takamiya's head, where Lucifer levitates Furuichi's "soul" over her palm with her power. She subsequently cuts it into six pieces and later sends them out across Ishiyama High School, each destined for a member of the Fallen Angels. Lucifer then disappears again at Takamiya's advice.

Later, Lucifer appears again to use her abilities against Oga once more; just as Takamiya prepares to punch the fellow first-year, Lucifer swiftly jumps away from Takamiya's arm so he can deal a successful hit. Standing from afar, she then watches the delinquents fight with a disinterested expression.

Powers & Abilities
Gravity Manipulation: Lucifer's main ability resides in being able to manipulate gravity, using simply her right hand as a perimeter to do so. She demonstrates her ability during Takamiya's fight against Oga. In this fight, she first users her powers to pull Oga and Baby Beel abruptly towards Takamiya so that he can punch the fellow first-year with a powerful uppercut, performing the exact same trick later on in a subsequent fight. With this ability, Lucifer can cause objects to float from the palm of her hand; however, she appears to require an electric-like link between her right hand and the objects which she is levitating.

Shinobu Takamiya
Despite having possessed him when he was a child, Lucifer and Takamiya are on amicable terms. She often rests upon his shoulder even during a fight and assists him when necessary. However, Lucifer usually lets him fight on his own and tends to disappear when she is not needed.
