Welcome to C.U.P.I.D.S.: the Cherub Union for the Preservation of Intimacy, Devotion and Sensuality.
C.U.P.I.D.S. is a covert agency tasked with creating love in the world. Armed with chemically engineered crossbows, cloaks and superhuman skills, these operatives have secretly controlled human romance for millennia. But their reign is threatened when a mysterious man, who calls himself "The Engineer," initiates a complex and destructive plan to end all love on Earth.
If the C.U.P.I.D.S. can't thwart it in time, The Engineer's scheme will trigger the decay of human civilization.
