Lucifer

is a Demon who once attempted to usurp the royal throne in the Demon World, and a member of the Seven Deadly Sins. 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 silver 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 white and very long, flowing down her back in a wavy manner.

Lucifer dresses in the Gothic Lolita fashion. She wears a light pink dress and a white, long-sleeved shirt underneath with frilly lace outlining the ends of her sleeves. The center of her dress bears a white stripe with thin lavender borders that extends from the top of her dress down to the ends of the skirt; several dotted lavender marks are patterned throughout the strip with small, lavender, 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 black 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 lavender rose with green leaves underneath and a white ribbon sewn beneath that, just under a bright blue jewel. Similarly, there is a large ribbon tied at the back of the dress near the same area. Lucifer wears a thin, frilled, light pink shawl over her shoulders that is held together by a white bow, placed beneath the collar of Lucifer's dress. A small, lavender jewel is sewn beneath the closed collar. Lucifer completes her outfit with black shoes.

Personality
Lucifer is an extremely silent and indifferent girl, practically to the point where she even appears mute. Instead, Lucifer communicates with her hair, using them as a type of feelers; she can also use her powers with this.

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
Before Beelzebub III united the Demon World under his rule, Lucifer was the queen of one of its countries. Sometime later, Lucifer fought against the Demon Lord for possession of the royal throne, effectively pulling the Demon World into turmoil.

Lucifer eventually fell into a deep slumber within an old castle, where she was later discovered by Takamiya's Father. He had her placed within a crate, marked by the number 02, and took her to his home. Lucifer continued to sleep until she sensed Shinobu Takamiya's hand near her face, quickly opening her eyes in alertness as she proceeded to touch his hand. Suddenly, dark threads emerged from her and they viciously attacked the men who brought her to the household, bloodying them and leaving the room in wreckage. Lucifer later emerged from the crate and used her hair to touch Takamiya's child-like face, staring intently in his eyes.

She later came to possess Takamiya, forcing them to live together in a dark room filled with spell tags.

Six months following their meeting, Lucifer used her hair to communicate with Takamiya and requested that she be brought outside. She then listened to him talk though she simply stared at him, even when he told her that he would like her to actually talk to him.

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.

Lucifer continues to assist Takamiya when they head to the rooftop with Oga and Baby Beel, where she uses her gravitational abilities to nearly send their opponents past the high fence and into the courtyards. When they manage to hang on, Lucifer decides to show them Takamiya's memories of his childhood when they first met. The transferring of memories ends shortly after.

Later, however, she becomes immobilized on the ground after Oga uses a surprising technique.

Powers & Abilities
As one of the Seven Deadly Sins, Lucifer has great power, and is stated to be on the same level as the Great Demon Lord, Beelzebub III. Gravity Manipulation: Lucifer's main ability resides in being able to manipulate gravity, typically using just her right hand as a perimeter to do so, although she can use this power without having to do so. She demonstrates her ability during Takamiya's fights 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. In a subsequent confrontation, she propels both opponents backwards and nearly knocks them off of the rooftop of which they are standing on. 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.

Memory Transfer: One of Lucifer's other abilities include being able to transfer the memories of one person to another. As a dark shroud envelops over her, with her hair moving freely through the air, she "streams" the memories directly to the person whom she wants them to see while looking directly at them. Lucifer is able to transfer the memories of a different person from before she met them, as shown with Takamiya.

Levitation: Lucifer can levitate her body above the ground. She can also freely move her hair at her own will, similar to that of feelers.

Shinobu Takamiya
Despite having possessed him when he was a child, Lucifer and Takamiya are on amicable terms. In the two years after they met, Lucifer spent her time in a dark room with him though she occasionally asked whether they can go outside together.

Presently, 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.
