Date A Live IV

Date A Live IV takes place in the world of Eurasia, 30 years after a catastrophic phenomenon known as the "spatial quake" killed approximately 150 million people. The quakes are still occurring, but on a much smaller scale, and the main protagonist, Shido Itsuka, navigates this world. Shido encounters a mysterious girl at the epicenter of a spatial quake and learns from his adoptive sister that she's a "Spirit," a being from a different dimension responsible for the quakes. To seal their powers, Shido must develop romantic relationships with these Spirits, which leads to a complex dynamic with multiple girls vying for his attention.
