>>27700361Ame isn't necessarily great at singing so she's not very likely to pursue song collabs. She does have 2 solo covers though. If they want a song cover with Ame, they would have to approach her with the prospect like Kiara did.
Gura does have a lot of song collabs, but it feels like it's more that Gura was approached by others because she has very little interest putting out solo covers.
