So she is the next color in the colorful Yakumo family XD ?

I think this is the most taboo pairing in Gensokyo.
One party would say, "Ran would never do that to Chen!"
The other would say, "Ran has been waiting to do that!"

Controversial! That was the word I was looking for, not taboo!

And some would say, "Ran has already been doing it all the time!"

But green is somewhere between orange and indigo. Could she be Chen's older sister…?
