Date A Live (Japanese: デート・ア・ライブ,Hepburn: Dēto A Raibu) is a Japanese light novel series written by Kōshi Tachibana and illustrated by Tsunako. An anime adaptation by AIC Plus+ was broadcast on AT-X between April and June 2013. Each episode was streamed in lower quality on Niconico a week before its TV premiere. The series continued its broadcast run with Date A Live II from April to June 2014, produced by Production IMS. A film adaptation premiered on August 22, 2015. A third season by J.C.Staff has been announced, and it is set to premiere in January 2019.
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, and is recruited 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 deep kiss with him. Shido's intelligent classmate, Origami Tobiichi, is a sergeant of the AST (Anti-Spirit Team), a special unit designed to suppress the threat posed by Spirits. As Shido successfully keeps sealing more and more Spirits, he gains allies to help him with his dates with other Spirits. Shido also increases the competition among them for his attention and affection, much to his chagrin.
