Kinda tempted to make a AU for Little Witch Academia, where Ursula is Akko’s adopted mum, and dealing with the struggles of raising a hyperactive daughter and fighting against stern teachers to make sure she gets an education at a fancy prep school that Akko got into a scholarship there for their music program.
With a twist being that Ursula used to be world famous rocker/leader of rock band, Chariot, before something made her disappear off the stage. Akko’s parents were huge fans before passing, and snuck Akko into one concert when she was little, making her into a mega-fan too. Though part of the obsession could be attributed to that being one of the last big memories she has being with her parents before a car accident happened with her being the only survivor.
And part of the reason Akko went for the scholarship is because she wants to be a famous musician like Chariot, and she went through the same school and program. Unfortunately, as the school is mostly focused on classical, Chariot became something of a blemish on their reputation, and so they think less of her, and of Akko for only wanting to be like her.
Other characters would be in there. Diana still a prodigy, probably with violin or piano, or perhaps maybe both or more, tipped to be the next big thing out of the academy. Lotte and Sucy are there studying music as well, Lotte probably folk music, Sucy into dark classical music/gothic music? Amanda and the green team aren’t in the music program, but excel at sports, cooking, and engineering. Croix later comes on as like a music expert/celebrity doing a favour to her old school by coming on as a teacher for a while, taking an interest in Akko, especially when she finds out about Ursula.
All this from Ursula’s mum attitude, and that I noticed Akko’s and Ursula’s eyes are pretty much the same.
