"The Usual Cliche" (from episode 8 of season 2)

My big sister is better than yours!! She's a beauty and her singing and dancing are top notch too!

Ruby's onee-chan doesn't fall short either! I think...

She can't do a backflip, can she!?

If it's a Japanese dance, she's already able to teach others! She can even play the koto!

That has nothing to do with school idols!!

That's not true!

Kanan-chan also said that the foundations were the same too!!
