eri would be so adorable in the bnha music au, and
i can totally imagine her performing songs from the musical Annie. she would be too shy to get on stage and sing alone, so professor aizawa (even though musicals aren’t really his thing) would get on stage and sing it with her (as Oliver Warbucks of course)!
she’d love singing ‘Tomorrow’ because it’s such a hopeful song after what she’s been through with chisaki. then she and aizawa would do a duet to ‘I Don’t Need Anything But You’. in the end, when she goes to live in the UA dormitories, class 1A and the big three would totally get all dressed up and sing ‘I Think I’m Gonna Like It Here’ to welcome her to her new home as aizawa’s adopted daughter. :’)
