Succubus (サキュバス, Sakyubasu) is a demon who seduces men so she can absorb their life energy. She currently resides in the first chapter ("Lust") of the Book of Eibon, after an unsuccessful confrontation with Noah resulted in both her permanent imprisonment and addition to his collection.
In a further attempt to attract men in addition to her rampantly seductive appearance, the Succubus conducts her movements in the most perverted way to expertly accentuate the most bewitching and attractive aspects of her female form. She is extremely erotic and flirtatious, but in fact, it is shown that she too has a strong lust for good-looking members of the opposite sex, which can be used as her weakness.
Befitting her need to entice men in order to fulfill her respective desires and vice, this particular demon has assumed an alluring form that she believes best caters to a perverted man's wants: A young and voluptuous female with an ample bust. Her softened facial features are contrasted by the stark addition of a vertical line descending from both of her eyes (Which are shown with heart shaped pupils); these lines are connected by a horizontal line that runs over the bridge of her nose, together creating an "H"-shaped marking.
The rest of her face is concealed beneath a layered and spiky hood, featuring two prominent curved horns (similar to a ram's) protruding from the sides. Further placing emphasis on her seductive qualities, the Succubus wears the bare minimum of clothing; consisting simply of skintight gloves and stockings decorated with "H"-shaped accents at their openings and a revealing apron that exposes the majority of her back, except for where a few small strands keep it attached to her body. This wardrobe choice's open back also prominently displays a...certain aspect of her appearance. A small, slightly coiled devil-like tail extends from just below the small of her back.
When the consequences of entering the first chapter of the Book of Eibon afflict various members of the Spartoi group sent to rescue Death the Kid (in order to serve him like a slave) with a sudden gender reversal, a strange yet shapely female leg emerges from one of the surrounding columns of fabric that inhabit this realm. From the narration provided by the Index, it is revealed that this appendage belongs to the Succubus, whose full form elicits a small trail of blood from the nose of the recently turned male Maka Albarn, who comically admits that she now knows how it feels to be a man. Her partner, Soul, who is not affected by the Succubus since he is now female, argues with her, asking 'what's so great about that thing?' resulting in an amusing switching of roles between the partners, as it is often Soul who breaks into a nosebleed and Maka that argues with him.
The Succubus continues to flirt with the 'male' members of Spartoi (who were originally female). Although Tsubaki manages to keep her feelings under control, Liz and Patti begin to notice the Succubus's attractiveness and Maka still cannot stop her nosebleed (which Soul doesn't hesitate to chastise). Kirikou, dismayed by his friends' actions (he himself is not affected since he is now female) turns to Blair. Since Blair is in her cat form, she looks no more different than she usually is, and Kirikou asks her why she is the only one who hasn't switched genders and wonders why she isn't affected by the Succubus. Blair replies that she is a seducer, not someone who gets seduced and that even as a tom (a male cat) that fact still remains true. She then smirks and states that in this erotic dimension, she should be a 'mindblowingly sexy devil.' She then goes on to transform into her human form. True to her word, she is an incredibly attractive young man. The Succubus immediately falls head-over-heels over Blair and rushes to her side. Blair compliments the Succubus's eyes, before telling her that she is 'sucked in.' She then uses her Halloween Cannon to blast the Succubus far away into the distance, before coolly remarking that they should be getting on to the next chapter.
- The character of the Succubus is in fact derived from the demons of the same name that often appear within actual medieval folklores, where these succubi conduct themselves in a similar manner to that envisioned by Ōkubo.
- The numerous "H"s on the Succubus's person are most likely a reference to the Japanese word ecchi, denoting sexually explicit material or behavior; "ecchi" is a spelling-out of the Japanese pronunciation of the letter H, and could have originated as a polite codeword for hentai in the 1960's.
- There is a small clothing fetish niche called hadaka apron, notably popular in Japan. Consisting of an individual -- Usually a woman -- wearing only an apron over their nude body or with minimal clothing, it is extremely popular on Japanese CG artwork websites and is accepted as the sign for newlyweds.
