Ai was scouted at a young age and became a member of the idol group B-Komachi under the Strawberry Production agency. Though she quickly rose to prominence for her charm and enigmatic allure, Ai’s life before fame was marked by hardship and loneliness. Having grown up in an environment where trust and affection were scarce, she developed a habit of lying to survive, believing that false love was still meaningful if it brought joy to others.

As her popularity soared, Ai’s desire to experience real love led her into a secret relationship. This resulted in an unplanned pregnancy at age sixteen. Unwilling to give up her dream of being an idol, she went into hiding and gave birth to twins with the help of a rural doctor, Gorou Amamiya, who was a devoted fan. Ai raised her children quietly while maintaining her public image, navigating the delicate balance between motherhood and stardom each role dependent on secrecy and sacrifice.

Ai was a stunning young woman with long, wavy magenta-pink hair, usually tied in pigtails, and vibrant, star-shaped eyes a signature trait symbolic of her idol identity and visual motif. Her eyes are later inherited by both of her children.

Her idol outfits featured bright, frilly designs with heart or star motifs, enhancing her innocent and ethereal persona. Even in casual settings, Ai maintained a cute and stylish appearance, in line with her public image. Her expressions were often warm and radiant on stage, masking the emotional complexity and weariness she carried behind the scenes.

On the surface, Ai was cheerful, flirtatious, and seemingly affectionate, embodying the perfect idol who made every fan feel personally loved. However, this was a carefully curated act. Ai believed that lying was a necessary part of being an idol, and she carried that philosophy into her personal life. She openly admitted that she didn’t know what love truly was but wanted to learn how to feel it one day.

Despite the lies she told to fans and even herself, Ai was not heartless. She cared deeply for her children and staff, often pushing herself to the brink for their well-being. Her biggest fear was being unworthy of love or losing everything if the truth came out. As such, she developed a persona built on performance masking her trauma, her insecurity, and her yearning for affection.

Ai’s character is a poignant exploration of the price of fame, the fragility of identity, and the blurred line between performance and authenticity. Her final declaration of love to her children, uttered while dying, was both her greatest tragedy and her redemption.
