I don't think her aunt is the issue per se, it's more the fact that Airi idolizes her and if she can't be on her aunt's level then she is a worthless worm in her mind. I perhaps should've used another word but is not like her aunts shits on her maliciously, she gives her pointers and sometimes makes fun of her in a playful manner from what airi says. Her aunt seems very chill and playful, it's just airi's mindset that holds her back unfortunately.I had my suspicions that Auntie Chisaka being a Tiger Aunt was the reason and being critical is fine I just wish that Airi didn't interpret it as her "not being a singer" when so many see she's one of the best! Sure maybe not Clara level but surely a notch or two below her.
