Patchouli smiling?
Honestly, it's the first time I see that in Danbooru. And even in the games, and in the doujins.

Speaking about that, I don't think I ever saw Patchouli smiling.
But it's nice, so it's okay.

There are several examples available, usually similar to post #674233, if you search patchouli_knowledge smile. But a smile this open and cheerful... I think I have to agree with you.

IRL seeing a girl like her smile is so beautiful it is addictive. You just wait and wait to see it again.

I wonder if we are going to see more art by Baniko.

She smiles (or smirks, anyway) in EoSD.
