Asa definitely Power bottom. Yoru definitely "introduced"her to it all since they share the same body, but Asa is the one calling the shots when they're at it.
We see time and time again that Yoru capitulates to Asa's feelings. Yoru ends up wanting what Asa wants. So if they were having sex and Asa had the thought that something Yoru did felt good, Yoru, completely disinhibited and feeling the same ecstasy, would also immediately do it more.
As strong as Yoru is she seems to get her feelings from Asa and also has the benefit of immediate feedback and shared sensation. She would also find it incredibly hot to be dominated by someone as gentle and kind as Asa. Asa would then enjoy having power and control over something for once, which creates an unimaginably strong feedback loop.
Would be really hot to watch Asa boss around Yoru.
