Akane or Akane-san was a girl who died of a sudden heart attack during a radio show in the old school. Since then, her ghost curses all those who hear her voice and they will die at the sunset of the same day. Satsuki puts her into spiritual sleep by repeating the number four several times (in Japanese culture, "4" is an unlucky number, because "shi", the word for four, is also the word for death), with Hajime finishing the process by ringing the bell that announced the end of the radio transmission. Voiced by: Megumi Ogata(Japanese), Alice Fulks (English). Akane didn't appear in Episode 20 when Ouma resurrected her.
- She seems to be inspired in Sadako from the popular Japanese horror movie Ringu, known in America as "The Ring".
