Mahou Shoujo Ai San - Season 1

The magical soldiers Ai, Rin, and Meg combat Yuragi, malevolent entities that emerge on city streets after dark. While these foes typically act alone, they have recently begun coordinating their assaults on young women for an undisclosed purpose. Central to these events are Shin and his young daughter, Mayu. Rin is Mayu's mother, having given birth to the child following an act of rape perpetrated by Shin.
