Date A Live II takes place in a world where Spirits, powerful entities that cause spatial quakes, must be dealt with either by force or romance. The goal is to seal their powers by making them fall in love, a strategy employed by Shidou Itsuka, who has already sealed three Spirits with Ratatoskr's help. Their efforts now face a new challenge, as a more significant threat detects their activities, complicating their mission to protect the world.
