Nemesis Gremory

Nemesis Gremory(ネメシスグレモリー; Nemeshisuguremorī) is the main antagonist of the second Volume of Highschool DxD: Legacy, and the Headmistress in Kuoh academy. She's the older sister of Berolina Gremory, Cohen Lucifer's first daughter and the granddaughter of Grandmaster Millicas, the most powerful devil around. She's the eponymous Crimson King, sharing the title with Berolina, of the said volume and the King of her own Peerage in the Underworld, consisted in 8 special pieces, with Aria Argento as her Queen.

Appearance
Just like any devil from the Gremory house, Nemesis has crimson red hair that she usually let it loose or wrapped it in a messy bun that resembles a flower, her bangs making a whirl turn with some rebelious string sticking out of them. She has a busty, curvilious figure, a mature and imposing, yet gentle facial estruture, fair skin and purplish red eyes, which irises are slightly slit because of her Alastor lineage from her father's side. She's taller than her Queen Aria, which is herself taller than the Narrator Ichijou. Her disguise in the human world has deep-blue long hair, blue eyes and smaller measurements.

Much like any respectful figure, Nemesis is usually wearing expensive, fancy outfits that avoid "showing off" too much of herself, like tube-dresses with fur jackets, expensive suits and pimp-up dresses. During more relaxed times, she wears casual, yet composed clothes, like kimonos, loose formal clothes or bussiness suits. Since the majory of her clothes is actually her power of destruction taking physical form, during battles she wears nothing but underwear.

Personality
Unlike her sister and father, who are complete jokers that laughs at any situation, Nemesis is serene, calm and serious but sometimes very strict and even violent. Being somehow a counterpart of ichijou, she can be lovable and gentle, but her emotions are usually very cold and passive, to the point people wonder if anything positive she ever says she really means it. Even Aria, her childhood friend and closest acquantance, have problems in reading Nemesis emotions. Even when frustrated or angry she has problems expressing herself, and end most up most of the time being more frightning that she intended to be. Because of their similar mentalities, Ichijou seems to see Nemesis clearer that the others, while her sister Berolina despises her thinking she's nothing but a bully big sister.

however, despite not showing too much emotions, Nemesis do love her peers and friends like any other Gremory. She does love Berolina, cares deeply about her well-being as well as her development as a King of her own peerage, but the fact that she diverged her pieces away made Berolina resent her since that day. Nemesis is also unable to say "I love you" or "I care about you", since she doesn't understand the meaning in naming concepts, that sometimes make people think she's a sociopath without the feeling of empathy. The fact that her demands and orders sounds like threats because of her usual calm, monotone tone only strenghten such rumors. Only a few people can see pass through such intimidanting figure and see her as a friend.

On a lighter note, Nemesis can create very healthy relationships with people that come close to her. She'd die and kill for her peerage, apologizes for her sister if she ever thinks her shenanigans had gone too far, and believes in true potential and the power of will, albeit the amount of it she puts in one depends on her first impression of the person in question. She likes the idea that Berolina is around people that trusts and likes her, while also concerned about their well-being because of her behavior. According to Nero and Aria, Nemesis doesn't like to stand out too much, and is very shy while face-to-face to people she doesn't known. Her favorite dish seems to be lobster.

When translated to japanese, she speaks in a distinctive Kyoto dialect, which is polite and soft, yet vague and indirect. She also uses 'Boku' as a way to refer to herself, which is usually used by young males, while being considered gender-neutral.

To be finished.
