This is a Touhou pairing I had not considered but I really like it.
Way back when I had only recently discovered Touhou Chen and Tewi were an immediate pairing for me. I knew nothing of the two characters at the time and simply paired them since I like the idea of loli cat and bunny girls together.
Chen and Nazrin is a pairing I see pop up now and then. That's another one I really like.
Perhaps Chen only pretends to be an innocent little girl in front of Ran and Yukari. When she slips out into Gensokyo she becomes the ultimate playa.
I wonder, ChenxTewi=Cabbits so what would ChenxNazrin and ChenxMomiji give us?
