25-year-old Hoshino Saki (Honda Tsubasa) is the brains of a mysterious specialist team called CHEAT, which deceives and exposes swindlers in return. Gifted with the ability to read people’s minds, she brilliantly corners them. However, she is actually a struggling third-rate idol with the stage name Kisaragi Momo. As far as Saki is concerned, this is her main profession. She was scouted by detective Anzai Kazuki (Kazama Shunsuke) and joined CHEAT in order to earn a living. Because the talent agency that Saki belongs to does not permit idols to work part-time, she cannot let anyone know about her activities with CHEAT. At the same time, she keeps her idol status a secret from the members of CHEAT. She pursues her dream of becoming a top idol while engaging in mind games with swindlers.
