Power Progression

Background / History

Ai was already an established member of the Dimensional Chat Group when Chen Mu and Tokisaki Kurumi joined. She helped reassure the anxious Gotoh Hitori, enthusiastically explained the Chat Group's cross-dimensional nature to Kurumi, and earned 100 Points for answering a newcomer's questions. 2

She introduced herself as a sixteen-year-old ordinary person working toward becoming an idol. At the time, she and Hitori shared the dream of becoming famous; Ai also began studying Kochou Kanae's Breathing Techniques for self-defense and fitness. 3 4 She had recently joined B Komachi and possessed some early recognition, though the group was still far from major fame. 6

Chen Mu's warning that she should not date soon was followed almost immediately by Kamiki Hikaru's confession. Intrigued by the apparent prediction, Ai rejected him because she had no plans to date and intended to question Chen Mu about how he knew. 7 Chen later revealed that Kamiki would impregnate, abandon, and ultimately arrange her murder; shaken by this possible future, Ai decided to focus on her idol career rather than romance. 11 12

As B Komachi's public face, Ai received a protective ring from Chen Mu. Despite manager Saitō Ichigo's concern that wearing a ring would damage her idol image or provoke dating rumors, she refused to remove it. 42 Her success also isolated her from the other members of B Komachi, whose relationships with her deteriorated as her popularity grew. 188

Seeking companionship outside the Chat Group, Ai invited Aqua to her world and proposed that they form an idol group together. Aqua accepted the invitation and entered Ai's world. 187 188 205 Ai later attempted to secure a uniquely close relationship with Chen Mu by offering to recognize him as her godfather, but he declined. 205

Personality

Ai is energetic, teasing, and quick to engage with newcomers. She playfully mocks Hitori's awkwardness, openly tags Chen Mu for answers, and readily turns extraordinary events into lively group discussions. 2 11 40

She is also stubborn when she has made up her mind. This is especially apparent in her refusal to stop wearing Chen Mu's protective ring despite the professional risks to her career. 42 Although she presents herself cheerfully, Ai feels the absence of genuine friends in her own world; her invitation to Aqua was motivated as much by loneliness as by interest in building a new idol unit. 188
