It was a family that lived an ordinary life. On a Sunday morning, a magic circle appeared in front of the family, and an ugly monster ran out of it. Just when the children didn't know what to do, mother Miyuki took out a strangely shaped mobile phone and used it to transform into an angel-like form wearing a white battle suit, and knocked down the monster in two or three strokes. After returning home, Miyuki told the surprised children that the monster that was defeated before was a dark beast from the underground underworld Inphisia that was sealed by the "Sky Saint" in order to invade the upper world. In order to fight the resurrected Inphisia, she was given the magic of the Sky Saint and could transform into a magician, the Magic Mother.
