Ai is the lead idol of the now-defunct B-Komachi. Originally hailing from an abusive and solemn past. Ai was a bumpkin with no professionalism and didn't try to fit in. Over time, through the help of producers and directors, she became an actual professional idol. She is a happy go lucky type of character. She hoped to, one day, find true love through all of her lies. She has two children. Aquamarine Hoshino and Ruby Hoshino but will never really tell anyone about this.
