I recently thought that it may be a good idea to make a pool with the above theme. It obviously comes from Ganbare! Kogasa-chan, but I see it elsewhere as well. Basically, it would be images that depict interactions specifically between Stage 2 bosses from Touhou games.
Team 9 images would not go here, because those depict more general interactions between the members. However, images with only Cirno and Mystia interacting would qualify.
Quick reminder: Stage 2 bosses are Cirno, Chen, Mystia, Hina, Parsee, Kogasa, Kyouko, and Kagerou.
I'm not sure if there's enough to justify making this pool; in fact, I don't even know if this is the right place to suggest this. I just thought doing this was a better idea than simply making a pool that may not be wanted.
If this is considered feasible, I can provide examples. If not, I'll leave it alone and never bring it up again.
