Date A Live Vol. 1 (Light Novel)

Shido Itsuka’s life has been a whirlwind as of late. Or more precisely, a spatial quake. Several of them, in fact. Powerful “Spirits” from other dimensions that take the form of girls are unintentionally causing these spatial quakes in his reality. And Shido is the only one who can stop them with his unique ability: kissing them! By having the girls kiss and fall deeply in love with him, their devastating quake powers are sealed. But an organization called AST (Anti-Spirit Team) isn’t interested in sealing their powers and is actively trying to eliminate them instead. Can Shido protect the girls by dating them and having them fall for him before they’re eliminated?
