Humans form history.

I bet it's only possible because their lives are short.

Humans really are such wonderful beings.

After all, they're fundamentally individual creatures that leave no offspring.

I've experienced so much different history with my eyes, my skin, my brain, but...

Hmmm.

They carry the past into the present, and their own history into the future.

Youkai can create their own history, sure, but it's rare for it to tie into someone else's future.
