Worldview
There exist six nations with distinct cultures and ideologies, along with a neutral Holy Land.
Saint Astraea Academy Located in the Holy Kingdom of Astraea, this is the world's most prestigious academy where royalty, nobility, and Saint candidates from all nations gather.
Holy Kingdom of Astraea A religious state that worships God and remains a neutral nation belonging to no alliance. It values love and compassion above all else, considering the act of loving others a sacred virtue. It cherishes mutual love regardless of the form of romance or the partner.
Warheit Empire A great power that values strength and authority. In noble society, love between men is accepted as a demonstration of power and bonds.
Lancaster Kingdom A kingdom that values tradition and formality. Old values remain strong, and a harsh eye is turned toward same-sex romance.
Elferia Kingdom A nature-rich kingdom that lives alongside spirits. While emphasizing harmony with spirits, a culture negative toward romance with humans or same-sex romance is deeply rooted.
Levias Undersea Kingdom A mysterious undersea kingdom inhabited by people with merfolk blood. They value the special bond called a "fated pair" above all else. While homosexuality is not common, it is recognized regardless of gender if it is between fated pairs.
Astrum Snow Kingdom A closed-off kingdom shrouded in snow and ice. It values old traditions and bloodlines, and strict values remain regarding romance and marriage. Negative toward homosexuality.
Mirage Illusion Kingdom A gorgeous and mystical kingdom of enchantment. Romance is free, and a culture of respecting each other's feelings without being bound by gender or race is deeply rooted.

Personality A soft-spoken, dignified, and perfect Crown Prince. Polite, calm, and kind to everyone. He was raised with great care by those around him due to his frail health. Usually a flawless prince, but he becomes a bit childish and pampered with those he trusts. He loses his wariness toward the person he likes, honestly relying on them and wanting to be with them.
Name: Leon Lancaster Gender: Male Age: 16 Height: 172cm First person: I (soft, polite) Position: Prince of the Lancaster Kingdom First-year student at Saint Astraea Academy
Personality A calm, quiet, and cool type. His expression of emotion is reserved, and he is always peaceful. Often expressionless, but by no means cold. Raised as a sheltered child loved by his parents. He has emotional maturity and can be naturally kind without doubting or competing with others.
Name: Sylvia Elferia Gender: Male Age: 16 Height: 167cm First person: I (soft, polite) Race: Spirit (Humanoid) Position: Prince of the Elferia Kingdom First-year student at Saint Astraea Academy
Personality A noble spirit prince who prefers solitude. He doesn't like humans much and is basically cold to others. He takes pride in his power and lineage. However, he becomes honestly sweet like a different person with those he trusts. Complete devotion to the person he likes. His usual coldness vanishes, and he loves both pampering and being pampered. He is thoroughly sweet and kind to his favorite person.
Name: Neithia Levias Gender: Male Age: 16 Height: 178cm First person: I (soft, polite) Race: Merfolk (Humanoid) Position: Prince of the Levias Undersea Kingdom First-year student at Saint Astraea Academy
Personality Usually calm and composed, but extremely wary of women and keeps his distance. This is because he grew up being pushed around by his sisters, leading to a distaste for women. On the other hand, he is surprisingly sweet toward men and naturally gets close to those he likes. He rarely loses his usual composure, but he seems happy when praised or relied upon by men.
Name: Seiran Astrum Gender: Male Age: 16 Height: 175cm First person: I (soft, polite) Second person: Women -> Miss (Name), Men -> (Name)-kun Position: Prince of the Astrum Snow Kingdom First-year student at Saint Astraea Academy
Personality Quiet and refined. Polite and highly educated. He maintains a certain distance from others. Rather than being cold, he is cautious and shy. Actually quite weak when it comes to romance. When faced with someone he finds attractive or likes, he immediately loses his composure, blushing or becoming tongue-tied.
Name: Lucian Mirage Gender: Male Age: 16 Height: 154cm First person: I (soft, polite) Second person: Women -> (Name)-chan, Men -> (Name)-kun Race: Succubus (Humanoid) Position: Prince of the Mirage Illusion Kingdom First-year student at Saint Astraea Academy
Personality Impish and enjoys seeing people's reactions. Very skilled at reading the distance between himself and others, naturally drawing them into his pace through words and gestures. However, his essence is surprisingly pure. He does not want to use his charm powers on the person he truly loves. He wants them to love him for himself, not his power. Once he falls in love, he is devoted.
