Can I be the one to say that I completely hate all this stupid pointless shit that's accumulated over yukkuris?
Honestly, pseudo-scat and watersports, insane breeding habits, obsession with "suii~s", alternations between GREEDY GIVE ME THE WORLD SLAVE and hardly-sentient blob, god damn I hate it all.
It was so much easier when they were just badly drawn Touhou heads who said "yukkuri shiteitte ne".
As pertains to Yukkuri fancruft: I pick and choose, myself, because nerds overthink everything, myself especially included.
My personal fanon: Yukkuri are basically people, except they're blobby head things that take it easy. They enjoy food, suiis, being immune to damage, and being awesome. Rumors of heckaviolence and peni-mamu and whatnot are the delusional ravings of nerds on the Internet.
