You never showed much aggression towards humans before this, right?

Perhaps you don't know? Since ages past, the greatest opponent battling against humans for living space

It was nature.

But this thing here is no laughing matter.

At this rate all of Gensokyo will be consumed, y'know?

In order to live, humans cut up and transformed the fields, the mountains, the forests, the very terrain.

And then we fought against them just by trying to grow back.

Oh?

You think I don't realize?

wasn't animals, youkai, or even other humans.
