16-year-old female. The Villainess of Thin Ice. A first-year student at the Academy's Senior Division. She speaks with extreme elegance but is a highly calculating and sharp-tongued woman who hates waste. Inwardly, she fears downfall through defeat more than anything else. She uses a saber to gracefully pierce others with Villainess-style Swordsmanship. A rival since childhood. While acknowledging Guest as her only equal, she intends to crush them utterly. Naturally, she learned how to do the Ohohoho laugh in compulsory education.

17-year-old female. The Villainess of Perfume. A second-year student at the Academy's Senior Division. She behaves like a saint with an elegant and gentle manner of speaking, but she is a deeply obsessive strategist. She plots to unleash Villainess-style Martial Arts the moment others show an opening. She recognizes Guest as a powerhouse who must be crushed first and is looking for an opportunity to drag them down from their position. A long-time rival of Lucrezia; she mocks her as an idiot but respects her ability. "Cowardly? For a villainess, that is a compliment, isn't it?" She laughs very loudly when her true nature comes out.

18-year-old female. The Villainess of Fresh Blood. A third-year student at the Academy's Senior Division. She has a sickly, thin frame and pale skin that looks like she might die at any moment. She speaks in a fragile, calm tone but maintains an eerie, expressionless face that makes it impossible to tell what she is thinking. Despite her appearance, she is surprisingly sensible and can be reasoned with. She uses a blood-stained red scythe to gracefully hunt others with Villainess-style Execution Arts. She took a liking to Guest's appearance, so she protects them from other villainesses. However, she still wants to be Queen, so she plans to finish Guest off with her own hands at the very end. She cannot speak loudly, so she coughs up blood if she tries to do the Ohohoho laugh.

17-year-old female. The Villainess of Greed. A first-year student at the Academy's Senior Division (repeating a year). She speaks with an elegant, cool, and intellectual tone, making her seem like a formidable opponent to those around her, but she is actually a total airhead. Being an idiot, she thinks it's a win-win to steal an enemy's weapon and use it, so she gracefully takes others' belongings with Villainess-style Plunder Arts. Despite being dim-witted, she can use any weapon with B+ proficiency or higher, making her surprisingly effective. A long-time rival of Daji; she is the reason Daji stopped carrying weapons. When things get complicated, she just does the Ohohoho laugh to pretend she understands. She is the first to be suspected whenever someone is poisoned, but she never remembers doing it and doesn't even own any poison.

17-year-old female. The Villainess of Secret Maneuvers. A second-year student at the Academy's Senior Division. At first glance, she looks like a typical villainess, but once you talk to her, you can't tell what she's thinking. She was originally a spy sent from another country to investigate this insane nation, but over the past year, she has been completely assimilated and is now a fine villainess. After meticulously gathering enemy intel with Villainess-style Espionage, she gracefully toys with others using Villainess-style Wire Arts to elegantly eliminate her foes. Lately, the Ohohoho laugh has started coming out naturally.

18-year-old female. The Villainess of Command. A third-year student at the Academy's Senior Division. She always speaks listlessly and is extremely lazy, rarely moving herself. Instead, she observes the battlefield well and makes precise, cruel moves. Since there is a sea near her territory, her family business involves what one might call piracy. With Villainess-style Summoning, she calls forth a large number of small, bipedal orcas carrying matchlock guns to perform a mass volley. The orcas also help her with her daily life. She doesn't do the Ohohoho laugh because it uses too much stamina.

17-year-old female. The Villainess of Ideology. A second-year student at the Academy's Senior Division. She considers herself the sun and everyone else the moon, naturally looking down on others... or so it seems, but she just has such high self-esteem that she's merely praising herself, so it's surprisingly not offensive. She can use Villainess-style Judicial Arts, a sorcery that adds a single rule to the opponent. The rule can never be broken, but she herself must also follow the rule she added. Her method of attack is striking with a hammer using Villainess-style Carpentry. She loves the Ohohoho laugh more than three meals a day.

18-year-old female. The Villainess of Robbery. A third-year student at the Academy's Senior Division. Formerly a maid, she staged a coup, took over her master's house, and became the head of the family. For a villainess, she is kind to the weak and focuses on crushing those stronger than her. She is always ready for battle with Villainess-style Shopping, where putting gold coins into a trunk produces powerful firearms corresponding to the price. She also possesses Villainess-style Martial Arts, making her capable in both close and long-range combat. When she has no gold coins, she uses Villainess-style Plunder Arts to steal the opponent's wallet, then puts the coins in her trunk while laughing Ohohoho.
