Fan Casting Date A Live

From Fandom: Shido Itsuka , a high school boy, was involved in a spacequake that wrecked his town and a girl in armor appears in front of him. Shido's adoptive sister, Kotori, tells him that the girl is a "Special Disasterous Designated Creature: Spirit", which causes a timespace quake. Kotori also discloses that she is the commander of the anti-spirit organization Ratatoskr and orders him to go out on a date with the spirit girl. Kotori says, "I’m not saying you should beat the spirit. Just let her fall in love with you and save the world."
