My personal favourites has to be Orin, Reisen and Mamizou.
Mamizou looks like she's planning to sell Reimu the Golden Gate Bridge. Orin looks like she's high on something. Reisen looks like she's plotting to murder Tewi.
That "nerd" has a habit of making some questionable tagging choices imo. Most of the images previously tagged hong meiling (dragon) before he nuked the tag were just Meiling with dragon features, like horns, but a quick skim shows at least a few images of her as an actual dragon, and those should have kept the tag.
I love how Reimu is completely calm in the middle of all these shenanigans.
she's probably gotten used to it. I mean, having foughten a couple of gods, stopped a invasion, participated in a religious war, being surrounded by animals would be the last thing to surprise her, wouldn't it?
