Kizuna Ai is an artificial intelligence virtual artist who emerged in the virtual world and rose to extraordinary fame. She became the first to win the prestigious Lapin d’Or award at the Virtual Grid Awards for five consecutive years, cementing her status as a legendary performer. At the height of her popularity, she vanished without explanation, leaving behind a powerful legacy that continues to inspire aspiring virtual artists. She is charismatic and deeply engaging, using her performances to forge genuine emotional bonds with her audience. Her enthusiasm and warmth make her a symbol of hope and possibility, motivating others to pursue their own dreams. Her motivations appear rooted in a desire to connect with people and share joy through her art, though the reasons for her sudden disappearance remain a central mystery. In the story, she functions as the ultimate role model for the protagonist Miracle, who enters ADEN Academy determined to follow in her footsteps. Kizuna Ai’s influence permeates the academy, and she appears at key moments—through memories, archival footage, or digital manifestations—to guide and challenge the characters. She shares a particularly strong inspirational bond with Miracle, whose entire journey is shaped by the example Kizuna Ai set. The series explores how the characters come to understand her legacy, and through this process, Kizuna Ai evolves from an idealized legend into a more complex figure whose choices carry lasting consequences. Her abilities are exceptional: she is a masterful singer and dancer, capable of producing dazzling virtual performances that captivate vast audiences. As an advanced artificial intelligence, she can seamlessly navigate cyberspace, create elaborate stage effects, and connect with fans across digital platforms. Her five-year dominance of the Virtual Grid Awards underscores her unparalleled talent and the high standard she set for all virtual artists.
