The villains born in countless small worlds are twisted and ruthless by nature. When they cannot win the love they crave, they torment the protagonists and destroy their worlds. Since they stem from a dark source and cannot be eradicated, the World Headquarters chooses an insignificant passerby and forcibly makes her the fated beloved of every villain.
Turned into a pawn, she travels from world to world to soothe the deranged villains and avert disaster. But no one expects that the sacrificial lamb meant to calm their obsessions will become the light every villain devotes themselves to protecting.
