I've read that body odor can play an important role on partner attraction/selection, you would prefer someone whose scents is different and pleasant to you. Also applied to kinship which gives similar odor to each other, and it is used to prevent incest.
That means Reimu x Marisa is the perfect partners <3
Hello. vanilla here.
This time's theme was: What if Reimu and Marisa's smells were compatible down to the DNA level...?
I bet Marisa's hair would smell like futon hung out to dry and white musk.
Also, I fiiinally started playing 100th Black Market, but turns out it's super difficult!! I haven't yet managed to clear it (I wish bullet hell games would love me). Have you done it already?
