Minerva is slim and has a distinctly Eastern appearance: long, straight, purple-black, waist-length hair with center-parted bangs on the forehead and hair tied into a bun on both sides, and the most Eastern feature of her face is her makeup, which is reminiscent of that of a Japanese "geisha". Her lips are painted with green lipstick, her glasses are tilted to give people a sense of horror, her eyelashes are long and thin, and she appears to have diagonal black spots that act as (cover) her eyebrows.
During her debut, she wears a strapless gown, similar to a cheongsam. After joining the Dreaming Eye guild, her attire is a black fur coat with exposed belly button, thigh-high stockings and high-heeled boots, and the Dreaming Eye guild crest is still on the left side of her waist. After being transformed into a demon and joining the Gates of Hades, the right eye and part of the body is covered with a black coat of arms, wearing a long black cloak, light-colored arm bands, black gloves, and knee-high black boots. Her entire body is covered in bandages, revealing the black crest of a demon and the "Gate of Hades" crest on her left waist. Minerva is a very calm and confident magician, who usually speaks in an ancient syntax, calling herself "my little daughter" and "my concubine", and has extraordinary strength, specializing in intrigue and power tactics. She has an irreplaceable position in the "Saber-Tooth Tigers", and regards the reputation of the strongest guild in the "Saber-Tooth Tigers" above all else, and is ruthless and will do anything to achieve her goal. He is outwardly very mature and wants people around him to behave in a proper and reasonable manner, but at the same time, he has a tendency to be abusive. For example, he abused Lucy Hattefelia by leaving her on the field in the "Sea Battle" match of the Daimonic Duel Tournament when she could have easily won with her magic, and he also used a trick to make Eloisa Shukaku and Kagura Mikazu to fight against each other, and he also used a trick to make Eloisa Shukaku and Kagura Mikazu to fight against each other. She also used a trick to get Eloisa Shukal to abuse Miriana because she was bored while she was fighting Kagura Mika Ziki.
Like her father, Jermaine, the former president of the Sabertooth Tigers, Minerva sees the Sabertooth Tigers as the strongest guild, one that can only be matched by the strongest, and weak magical guides are no different than trash. When her plans are thwarted by her opponents, the usually calm and haughty Mineba becomes furious, and when her own plans are completely thwarted, she will cry from the humiliation she feels. But Minerva seeks revenge for this humiliation, and this twisted personality for the sake of being the "strongest" pushes her into darkness.
Because her father, Germaine, had instilled the idea of "being the strongest" in Minerva when she was a child, and had verbally abused and beaten her because she was too weak to bear "the strongest blood," this childhood experience led to the distortion of Minerva's character, but her heart was not bad at all. But her heart is not bad. This distorted character forged her belief that she wanted to enter the strongest guild, and after Sabertooth Tiger lost to Goblin's Tail in the Grand Magic Tournament, Minerva left Sabertooth Tiger to enter the dark guild "Dream Demon's Eye", with the purpose of "going farther", believing that the so-called "loyalty to the guild" was not enough. Minerva's goal was to "go farther", believing that loyalty to the guild would not help her become the strongest, and not caring if her way was the "right" way permitted by the law. The Dark Guild has a lot of interesting magic, and only the strongest guild, even the Dark Guild, can match her strongest, Minerva's confidence shows.
