Mikuriya Jin makes a woodcarving from the remains of a guardian tree, but he gets much more than he bargained for when girl materializes from the statue! Her name is Nagi, the troublesome and at times violent deity of the land; and with nowhere to go, she announces that she will stay with Jin. Now, with Jin’s help and a magical girl wand purchased at the local convenience store, Nagi aims to exorcise the impurities that are infecting the land. Though when the sacred tree is finally uprooted, it is only a matter of time before her powers will diminish; thus, a new object of worship is required, and what better object than Nagi herself! However, obtaining your goal of becoming a popular idol is not so straightforward, especially when you have to compete with your sister, who is unwilling to share her fan base and plans to sabotage you at every step!
In a world where magic is a reality, the young Louise is at the bottom of her class. Dubbed "Zero" by her classmates at Tristein Academy (due to her zero success rate for magic), Louise (along with all first year students) was charged with summoning a familiar; and instead of a cute magical creature, the familiar arrived in the form of... Saito Hiraga, a normal Japanese boy who was abruptly teleported from his own world?! Can both Louise and Saito come to terms with their new and complicated "relationship" and (more importantly) help Saito find a way home?
