The Aozaki family oversees the land on which Misaki is built and the heir is tasked with protecting it. Mysterious intruders have been disrupting the bounded field in Misaki, leading Alice and Aoko to investigate. A mannequin or puppet attacks them and is incinerated. As this happens, both of them spot someone running away, a civilian who must not get away having seen magic alive. Unexpectedly, a young boy named Sōjūrō Shizuki is drawn to the mansion and comes to reside with them as well.
Eventually it is revealed that the intruder who had been disrupting the bounded field is Touko Aozaki, Aoko’s older sister. She, having killed their grandfather, now seeks to unveil the Aozaki’s path to the root.
