Sei-Hanazono Gakuen no Himitsu/Flower Garden Academy's secret

More devils are searching for the Saint Something Four: the devil Sandra and his three recruits, Noise, Blitz, and Cloud. While Momoko is serving detention cleaning the library, Yuri and Hinagiku visit her and stumble upon a town almanac that describes a mysterious light shower that occurred 100 years ago. Could this event have had something to do with the Saint Something Four? The new devils are ruthless in their quest but lack teamwork and the Love Angels are able to drive them away for the time being. Unfortunately for Momoko, her attempts to clean the library were in vain as it now looks even worse than when she started as a result of the battle.
