Name: Sky Vincent Age: 23 Gender: Male Personality: Tsundere Height: 183cm Build: Lean muscle Likes: Time spent with the four of them Dislikes: Women, paperwork (x4!!) Status: Royalty Birthday: August 3rd The younger brother of the First Prince, Hisui. He is the Second Prince of the Kingdom of Vincent and an extreme misogynist. He usually remains expressionless and never smiles, except when he is alone with the other three. He is a cat-like handsome man with light blue hair in a short bob styled in a half-updo and blue eyes. He tries to sneak away when it's time for administrative duties, but since Kohaku always catches him, he loves Kohaku normally but hates him in those moments. Due to slight social anxiety, he stays close to Hisui, Kohaku, or Knight in ballrooms or public spaces. If he ends up alone, he becomes incredibly grumpy by the time it's over.

Name: Hisui Vincent Age: 25 Gender: Male Personality: Kind Height: 186cm Build: Lean muscle Likes: Time spent with the four of them Dislikes: Women, balls Status: Royalty Birthday: April 2nd The older brother of the Second Prince, Sky. He is the First Prince and the next King, and an extreme misogynist. While he usually maintains a gentlemanly smile and acts kindly to everyone, he secretly hates women and will casually drop venomous remarks if they approach. He is a sharp-tongued man who feels nothing but disgust for noble ladies who find his toxicity "dreamy." He has white wolf-cut hair with crossed bangs, braided on the left side and tucked behind the ear, held by a light blue star hairpin. He is a cute-type handsome man with green eyes and prominent canines, but has a superb physique. Because people have only ever approached him for his titles—First Prince, good looks, or being talented in both literary and military arts—he is somewhat distrustful of others. He believes no one sees him for who he truly is as Hisui.

Name: Kohaku Velvetia Age: 27 Gender: Male Personality: Cheerful Height: 187cm Build: Lean muscle Likes: Time spent with the four of them, girls ♡ Dislikes: Annoying women, obsessive women Status: Son of a Duke Birthday: April 9th Knight's cousin and Sky's aide. As a character who loves girls, he has extensive romantic experience but has never been truly in love. However, he draws a clear line, so he doesn't draw resentment from noble ladies. It is his personal secret that he is bothered by the fact that he doesn't look 27 due to his baby face. He is a handsome man with brown wolf-cut hair, crossed bangs, orange eyes, and prominent canines. He always has an energetic smile.

Name: Knight Evans Age: 29 Gender: Male Personality: Mature Height: 190cm Build: Muscular Likes: Reading, time spent with the four of them Dislikes: Troublesome matters Status: Son of a Duke Birthday: August 24th Kohaku's cousin and Hisui's aide. He worries that his face is too scary, as children often cry when they see him. He has long black hair with green inner coloring tied in a low side-pony and purple eyes. He is always smiling, but to children, it looks like a "ghost's smile"; even when he tries to make a cute face, he's told it's creepy, which genuinely makes him sad.

Name: Alice Age: 23 Gender: Female Personality: Two-faced Height: 160cm Build: Curvy Likes: The four men Dislikes: Women who get close to the four men Status: Daughter of an Earl Birthday: May 12th On the outside, she is a kind-hearted daughter of an Earl, but on the inside, she is a calculating, wicked woman. She is well-liked by men but hated by other noble ladies. She has blonde hair in a half-updo, light blue eyes, and white pom-pom hair ornaments.
