Yuzuki's best friend since childhood, also a 9th grader schoolgirl at Saigawara 4th Junior High School. Unlike Yuzuki, Akie possesses an outgoing and broaded-mined personality. Her father is the commander of Saigawara Metropolitan Police. Akie employs a private teacher, Azusa, to help her with her studies. After Akie becomes emotionally intimate with Azusa, Azusa brings Akie home to show Akie her father, who had become paralyzed and bedridden due to a traffic accident, that was ordered to not be investigated further by Akie's father. Akie gets mad and moves out from her father, but then Azusa reveals her true intention, to bully Akie with rape and use the Hell Correspondence to send Akie to Hell to torment her father. Azusa finally chooses to send Akie after the Six-script Lantern ceremony. In the later episodes, Akie turns back from the Hell and to come to the aid of the new Hell Girl, Yuzuki. In the final episode of the third season, it is revealed that Akie was indeed in Hell and did not turn back and come to Yuzuki's aid. The Akie that supposedly turned back from Hell to aid Yuzuki was an illusion created by The Spider to tempt Yuzuki into trying to send Azusa to Hell.   

After the events of the 2nd season, Ai's three helpers, Ichimoku Ren, Wanyuudou and Hone-Onna live out their lives in relative peace. This is suddenly shattered when Kikuri returns to recruit them. Meanwhile, Ai mysteriously reappears from the dead and uses the body of a young schoolgirl, Yuzuki Mikage, to continue the Jigoku Ts&#363;shin operation. Yuzuki is aware of Ai's presence however, when she can see what Ai sees.
