[The mention of 'Love Live' doesn't seem to ring any bells. How awkward (for Natsuru). But then, she'd never heard of any of her other idol friends before coming to this place, either.]

Other school idols? I don't think I've met any yet...

Ah, but there are other idols here! There's Sayaka, and Minako-chan's even a goddess of love too! Rise-chan, Athena-chan, Chieri-chan and everyone used to be in our group too, but they've all been sent home.

[She didn't list herself as one of the idols, but she did say 'our group'...]
