This is probably gonna be more tribalfag fuel, so sorry in advance, but it's genuine curiosity, no tribe autism intended. Is it me, or does the "major appearance in the other company's individual project" thing feel like kind of a one-way road? I'm not referring to group streams, more along the lines of how Himawari popped up on Polka's show, or how Toko and Hoshikawa appeared on Suisei and Haachama's 3D streams/concerts. What were the cases of the other way around happening? The main one I can really think of is Subaru popping up for Maimoto years ago, like sending a birthday message or playing in the 2019 Niji Koshien.
