Reading, fashion, relaxation
Acht is a pale-skinned woman with blonde hair and green eyes. Her hair is waist-lengthed and curls upward at the tips; her forehead is exposed and her bangs fall to her shoulders on each side. Her hips and chest are fairly large, and there is a mole under her left eye. During her Drive Veil Skin, all of her skin except her face becomes a greyish blue; crystals cover her arms, chest, legs, crotch, and jaw.
Acht's normal attire consists of a blue, button-up corset with black and yellow trim. She wears two sets of underwear; a black pair with a blue pattern that rides at the edge of her corset, and underneath that, a black pair that hugs around her hips. She wears sagging, black trousers that start near her crotch and fall down under her knee; it also has a silver zipper. Over these pants, Acht wears long, black, high-heeled boots that go up to the middle of her thigh. The boots puff out at the top and have a black trim with silver ornaments decorating the front. She wears a long, black jacket that reaches down to her ankles from the back; from the waist the jacket is pleated. The inside of the jacket is blue, and the sleeves have a cuff with yellow trim. The top of the jacket has a blue pattern and a window exposing the cap of her shoulder, and at the neck, the collars pop out; the collar is joined by a blue ribbon. Over her jacket, she wears a large, black cape that she wears over her shoulder and tucks under her right arm. The cape has fur trim. Finally, Acht wears large sunglasses that she wears at the top of her head.
On the surface, Acht is polite and courteous, if not slightly condescending. When pushed to fight, however, she is maliciously cold, Acht treats those she deems under her as rough as she possibly can. She revels in taunting her enemies and has no qualms about attacking those weaker than her so long as it is part of her mission. Acht recognizes her actions as being morally reprehensible, even calling herself a "cruel witch" after holding Hinata Himezuru hostage. She finds Touya Kagari annoying, loud, and obnoxious, and dislikes him so much that she has no problems with attempting to kill him.
Acht enjoys fighting, being disappointed when she is unable to brawl because of her orders. She displays a confidence in her magical abilities that borders hubris. Acht left Ishana to follow Sechs, whom she loves, even allowing herself to become a Union just to help fulfil his goals; apparently using her Drive makes her giddy with excitement. She has a flair for the dramatic, pretending to be in pain and screaming when Kuon Glamred Stroheim attacked her using magic which did nothing because of Acht's own Drive.
Yet, Acht is not completely devoid of any positive qualities; even knowing that her leaving Ishana would lead to her execution, she still left to be by Sechs side out of loyalty and love. When confronted by Kuon, she parted her with advice, telling the younger Mage that she needed to learn to take responsibility for her actions. Most of Acht's more questionable actions happened when her Crystal had gone into its later phases, symptoms of which include mental instability. When close to Phase Six, her mental state had deteriorated to the point where she could not reason, only being able to instinctively yell and throw out powerful magic.
In her spare time, Acht likes reading and relaxing. She follows fashion and likes finding out the secrets of others.
