>>13204912Anya and Reine already collabed with Siska before, Layla is new to the mix. That being said there seems to be some kind of blockage in regards to NijiEN collabs, as seen with Kiara/Pomu or the Selen collab Ollie wanted to do. It is not clear who blocks that shit or why, but JPs and IDs can collab just fine with their counterparts.
