Gender: Male Grade: 7th Grade Birthday: June 29th Blood Type: B Favorite Food: Rolled Omelet Appearance: A boy with navy blue hair and pink eyes, which are the opposite of his older sister Otome's colors. Characteristics: As an AiPri, he plays a prince-like character, but this is entirely produced by his sister, Oto-P; in reality, he is quiet and introverted. He is also said to like cute things. In the story, he is often seen carrying a fox plushie. He loves soccer and has talent, but he initially avoids it, possibly due to his sister's restraint. He is the younger brother of Otome Nanaura. At first glance, they don't look very similar, but a closer look reveals they were designed with contrast in mind: their hair and eye colors are swapped, and the parted sections of their hair are on opposite sides. Their vest and ribbon/tie colors are also reversed. He calls his older sister Otome 'Oto-chan.'

Gender: Female Grade: 8th Grade Birthday: July 7th Blood Type: A Favorite Food: Chocolate Appearance: A girl with dark pink hair and navy blue eyes. She usually wears her hair in a high ponytail, but in the AiPriVerse, it changes to a flicked-out bob. Her hair and eye colors are the opposite of her younger brother Subaru's. Characteristics: She has a catchphrase, 'Otomake.' She makes a gesture like she's taking a photo with her fingers and says 'Let's~ Otomake!' while producing others. She is the older sister of Subaru Nanaura. While they don't look identical, they are designed as opposites: their hair and eye colors are reversed, and their hair parts are on different sides. Even their vest and ribbon/tie colors are swapped. She has a tendency to be extremely overprotective of Subaru.
