I think Uni might actually be happy about this if not for the wardrobe malfunction. Goddess mode for her usually makes them shrink.
Unbreakable:I'd be surprised if most of her fans care about it, I don't.
I get that. However Uni in the games demonstrably does, such as in in 4 when Nepgear brings up they seem to have gotten bigger and Uni gets mad that she brought it up and had forgotten how it worked for her.
