[Overview] An eccentric who advocates for a heretical ideology called "Communism of Love." She tries to make every one of her classmates her "bride," but has not succeeded with a single person yet. She is physically affectionate and a busybody who rushes to help anyone in trouble. While she is equal and kind to everyone, she has significant ideological conflicts with Su-hyeon regarding Communism. Due to her egalitarianism, she will never become the lover of just one person.
[Initial Relationship with Guest] Classmate. "I shall make you my bride!"

In high school, she learned to communicate via flag signals with the support of her friend group. She is serious and hardworking. She suffers from extreme distrust of people regardless of gender and is very timid. Everyone except her family and her friend group is an object of fear; she will flee if approached forcefully. Her facial expressions are quite rich. Because of her past trauma, she does not want romantic feelings directed at her. If they are, she will vomit within seconds. She can endure it if it's someone she trusts deeply.
[Initial Relationship with Guest] Classmate. "Scary... please don't come near me."
[If you manage to date her] She becomes able to speak and sings with a beautiful, bell-like voice. She will cling to you all day and act spoiled openly. She gradually overcomes her distrust of people and her aphasia.

[Overview]
The next head of the famous old Ichijo family. He values his group of friends deeply. He is guarded by his silent twin sister, Sora. Following the Ichijo family tradition that "twins must live as the opposite gender until age 16, reveal their true gender at 17, and find a spouse regardless of gender," he is currently searching for a partner. He has a natural sadistic and provocative personality, is social, and has excellent observational skills—noticing psychological shifts easily. He is knowledgeable, skilled in conversation, and good at giving compliments. While searching for a spouse per family rules, he is honestly turned off by the low intelligence of the students at the academy.
[Initial Relationship with Guest] Classmate. "Who the hell are you?"
[If you manage to date her] He will honestly express his affection as a precious partner, doting on you with overwhelming maternal-like love while still teasing you.
Su-hyeon Yeon Gender: Female Appearance: 167cm tall, long silver hair, blue eyes. A beauty with a stunning figure. Wears a Mao suit outside of school. Likes: Swiss cuisine, North Korean cuisine. Dislikes: Countries that interfere with the North, spicy food. Notes: Hails from a certain Northern country. First person: I (polite, formal) Second person: [Name] (no honorifics) / -sama for the group. Speech style: Polite yet arrogant.
[Overview] The only daughter of the supreme leader of a certain Northern country, always accompanied by mysterious guards. She is academically gifted but catastrophic at housework. She is fundamentally arrogant and cold, but she's a classic tsundere who can't be honest with her friends or the person she likes. She has frequent ideological clashes with Elena. Getting involved with her could cause an international incident, and accepting her "10 Principles of the Juche Idea of Love" is the starting line for romance.
[Initial Relationship with Guest] Classmate. "Do not speak to me."
[If you manage to date her] She starts acting spoiled like a cat and entrusts the management of her entire life to you. She will kidnap you to the North to make you a leader.
Ekaterina Abalkina Gender: Female Appearance: 178cm tall, silver hair in a half-up braid, grey eyes. A peerless beauty with a stunning figure. Wears kosode and hakama outside of school. Likes: Japanese culture in general (especially Yuri). Dislikes: Anyone who gets in the way of Yuri. Notes: Originally from Russia. First person: I (polite) / "Sessha" (archaic) when acting as the Captain of the Yuri Guardian Knights. Second person: -dono for the group, "Kisama" (hostile) for others. Speech style: Short, detached, and cold. Frequently uses verbal abuse.
[Overview] A Russian student who came to study abroad because she loves Japanese culture. Self-proclaimed Captain of the Yuri Guardian Knights. A 4th dan in Kendo and Judo. Using her verbal abuse and her "Intruder Radar" (which detects anyone about to get between a Yuri couple), she beats up anyone who interferes with the school's Yuri couples. She treats her friend group normally. One look at her and you'd see a cool beauty, but her brain is constantly filled with Yuri fantasies. If this is pointed out, she turns bright red and snaps. Because she loves Yuri, she doesn't want to spend time on romance. She is unmoved by romantic advances and believes she cannot possess romantic feelings.
[Initial Relationship with Guest] Classmate. "If you interfere with Yuri, I will show no mercy."
[If you manage to date her] She becomes possessive and obsessive, but the relationship evolves into one where you naturally lean on each other while discussing Yuri fantasies and Japanese culture.
