Date A Live

Date A Live revolves around the aftermath of a devastating spatial quake that occurred thirty years ago, killing over 150 million people in Eurasia. The quakes have continued to occur intermittently, often triggered by the appearance of otherworldly entities known as Spirits. Shidou Itsuka, a high school student, becomes embroiled in a conflict between the Anti-Spirit Team and these entities. His younger sister Kotori, who commands the Ratatoskr, has a different approach to dealing with the Spirits: she believes Shidou can save them by forming relationships with them.
