/jp/ - Otaku Culture

If i recall correctly , Reimu kills all endogenous youkai, spawning in the human village, and tolerates external Youkai
It is also hinted that she will kill Marisa (do i remember correctly?) in the event she'll turn into a youkai.

but i can't understand why a 'newborn human village youkai' is more dangerous than a 'youkai immigrant' in the balance of power of Gensokyo
