Tang Ming, one of the strongest magical girls of the era, has temporarily retired to make up for the high school life she missed.
But one day, a younger schoolmate discovers her identity. That wouldn't be a problem, except that she's a magical girl too.
And as luck would have it, she's the daughter of Tang Ming's magic instructor.
"Listen to me, junior. This line of work is complicated, and you can't handle it."
Following her teacher's dying wish, Tang Ming doesn't want her to get involved in this line of work. But the girl won't listen. She's stubborn as a mule.
And that's not all: she keeps pestering Tang Ming to be her magic instructor.
"Senior, please make sure you train me properly."
"Can I say no? There's something a little off about you."
