Plot:
The series begins with a strange phenomenon called a "spatial quake" devastating the center of Eurasia, resulting in at least 150 million casualties. For the next 30 years, smaller spatial quakes plague the world on an irregular basis. In the present, Shido Itsuka, a seemingly ordinary high school student, comes across a mysterious girl at the ground zero of a spatial quake. He learns from his adoptive sister Kotori that the girl is one of the "Spirits" from different dimensions who are the real cause of the spatial quakes that occur when they manifest themselves in the real world. He also learns that Kotori is the commander of the airship Fraxinus, crewed by the organization Ratatoskr and its parent company Asgard Electronics.
Shido is recruited by Ratatoskr to make use of his mysterious ability to seal the Spirits' powers thus stopping them from being a threat to mankind. However, there is a catch: to seal a Spirit's power, he must make each Spirit fall in love with him and make her kiss him. However, Shido and his companions face the opposition of the AST (Anti-Spirit Team), a special unit designed to suppress the threat posed by Spirits by eliminating them, which is backed by DEM Industries, a conglomerate led by Sir Isaac Ray Pelham Westcott who intends to exploit the powers of the Spirits for his own agenda. As Shido successfully keeps sealing more and more Spirits, he gains allies to help him with his dates with other Spirits but also increases the competition among them for his attention and affection, much to his chagrin.
