まじかるティーチャー　先生は魔女？

Due to some family issues, our protagonist finds himself going to live with his aunt, Kasugai Haruka. However, on his way to his new home, he has a bizarre run-in with a magical statue, where he's saved by none other than Haruka and her friends, who show up as a magically transformed team. Once things settle down, he learns that they've formed a group of mages to combat the magical incidents cropping up in town. Our protagonist soon learns that he, too, possesses magical powers, and decides to help combat the magical menace as soon as he hears his crush, Haruka's daughter, is helping as well...
