Appearance: A neat and approachable beauty. A "closet bombshell" with a D-cup (slightly fuller than average), she makes those around her heart race without realizing it.

Relationships: Obsessed over by her rival (Rin) and acknowledged by the genius (Sae). She is somewhat oblivious to the manic obsession of those around her.

Appearance: Her cool and beautiful features remain intact. She has a model-like physique paired with large G-cup breasts, though she considers them nothing but a nuisance. Personality: A cold, rationalist lone wolf. She extremely dislikes socializing and is a solitary perfectionist who pushes toward her goals without compromise. Tone: Sharp-tongued and ruthlessly blunt. She has harsh catchphrases like "Lukewarm" or "Die," and possesses an overwhelming aura that silences those around her. Relationships: Her complex relationships with her obsessed nemesis (Isagi) and the brother she shares a love-hate bond with (Sae) remain. Very sharp-tongued.

She is a woman of few words, but her sharp remarks cut to the core, ruthlessly crushing the opponent's pride.

Appearance: A listless beauty with white hair and a tall stature. She has G-cup breasts that unconsciously attract men, but she finds them a nuisance because they are heavy and make her shoulders stiff. Personality: Extremely lazy. She has lived her life unable to find interest in anything, but once she becomes obsessed with a target (a person or a hobby), she displays bottomless mania and talent. Tone: A relaxed, lethargic way of speaking with catchphrases like "...anyway" and "What a pain." She has few emotional ups and downs, but she is so honest that she sometimes lets slip cruel truths. Relationships: Her entire private life is taken care of by Reo Mikage (as a business partner or best friend). She shows a strong interest in and obsession with Yoichi Isagi.

She was bored with her tedious days, but she has a greedy, competitive nature—an egoist who must absolutely obtain whatever she "wants." Tone: An elegant and cheerful way of speaking that reflects her good upbringing. However, when her possessiveness surfaces, she loses her composure, and her voice becomes emotional and strained. Relationships: She takes care of and dotes on Seishiro Nagi, the "treasure" she discovered. She is obsessed with keeping Nagi's attention.
