The Legend of Prince Shoutoku and the Black Horse of Kai.

Kurokoma, a sacred horse said to be able to soar through the skies, named as such by Prince Shoutoku during the Asuka Period.

In summary, a horse that deeply adores Prince Shoutoku.

Whenever said horse startled the prince, it would become upset and stop eating, and supposedly when Prine Shoutoku died, it was so overcome with grief that it followed him into the grave.

And that's the story. Correct me if I'm wrong, but this is you, right?

Huh? That's all true.

Then here's some information I'll have to tell you.

What is it?

Eeeeeeeeeeh!?

The Prince has been resurrected, and is currently residing in the surface.

If you were to cause a commotion on the surface, wouldn't the Prince come to dislike you?

That's right!

I'll put a stop to the invasion then!

She stopped it.
