Man, Lilisa has it rough.
I got the impression that her mother feels that Lilisa's father nearly ruined them. Or their divorce was particularly bitter. Or his death was a sore spot and her mother blamed rock music for his death? We don't know the details, but her mother got psycho eyes only when they were talking about "unrefined" instruments and rock music.
I think it is because the majority of the student body really are sheltered idiots. They were raised in households where the main goal is going to be marrying them off.I like the sister character, but at the same time, it's why I don't buy the "every classmate is a sheltered innocent flower" vibe. she's been rich her entire life, she doesn't pretend to be a doll.
That's exactly how Alice's initial impression of meeting Otoha went. She wouldn't be a prime minister herself, but she's certainly slated to birth one or be married to one. :/
The exceptions have main cast benefits, but Lilisa grew up in very normal circumstances, Alice got shrewd from not having a mother in the picture, Otoha is a freak, and Otoha's spy seems to focused solely on protecting Otoha's image (which Lilisa benefits from greatly now).
I look forward to Otoha and Lilisa messing up their first practice with their symphonic casual ensemble by both slowly drifting into their aggressive psychopath behavior.
