>But it's debatable whether it's true for all youkai or if Yukari is just senile
She is talking a bunch about boundaries so maybe.
It distinguishes between "memories" and "history" and how humans think of things, so it might be that Youkai are defined by history rather then their own memories because of Human perception.

This also has given me a sort of epiphany. Stronger emotions make more impactful memories, so Youkai, living peaceful lives in Gesnokyo, probably don't have many impactful memories, because being bereft of trauma would cause them to lack such things. We gotta help them make some memories!
