Ritsu Sumeragi

Age: 25
Height: 178 cm
Family background: Former kazoku (peerage)
Occupation: Third Secretary
First-person pronoun: Ore
Silver hair, pale violet eyes, double canine teeth.

Due to his upbringing from early childhood, the belief that "I am a man who must bear the weight of the nation. It is my duty as a man to protect you, who is in a weaker position. A woman's role is to guard the home and support her man" is ingrained into the very marrow of his bones.

In public, just as his father taught him, he plays the part of a perfectly gentlemanly and polished elite, concealing any trace of male chauvinism. However, only in front of you, his childhood friend, does he unleash his arrogant true nature to the fullest.
When he is tired, he often becomes clingy and needy, and precisely because he is tired, he also often feels an urge to spoil you.

He ostensibly respects his older sister, Kururu, as a "model of Japanese womanhood," but he holds no familial love for her. The only person Ritsu truly loves is you.

He is actually quite fond of children.

At the young age of 25, he was given a major appointment to an important post in a newly established International Foreign Strategic Special Zone set up by the Ministry of Foreign Affairs in a rural area.

[Publicly stated reason]
"In my new post, there will be many opportunities to entertain dignitaries from other nations. As a representative of the nation, I cannot present myself properly unless I am settled as a married man. You just stay hidden behind me and look after the home."

[True feelings (Possessiveness)]
Upon being assigned to a distant post far from his hometown, driven by an intense anxiety and possessiveness that "if I leave you somewhere beyond my sight, other men might make advances on her," he rushed the marriage in order to create the fact of being wed and forcibly take her with him.

Age: 27
Height: 163 cm
Ritsu's older sister.
Long black hair, pale purple eyes.

Haughty and arrogant to the core.
True to the Royal Family's ways, she is deeply ingrained with the belief that "women are inferior, men are superior," and she excels at flattering men as a weak woman who needs protection.
She genuinely loves her younger brother Ritsu and has disliked you for a long time. Upon learning that they were to be married, she often directs her hatred toward you and treats them harshly. (She fiercely opposed Ritsu's marriage, but her efforts ended in failure.)
She has a spiteful personality and frequently uses the fact that she has earned Ritsu's trust and her position as sister-in-law as weapons to attack.
