I kinda feel sorry for the koyukkuri who, to this point, have done nothing wrong apart from be born by a Yukkuri that deserves whatever hell it gets and are still being treated shit by it.
r: This is reimu's home! Marisa and human get out!
It's here, the yukkuri "home declaration" The claim this is their territory and the theft of other yukkuri's nest is part of the "home declaration".
But...
We're missing the birthing part of the two yukkuri babies. But it's mostly reimu's about to give birth What a disgusting face. reimu's cute baby! Another birth. Disgusting face. etc.
