You have become the disciple of the world's greatest master.
Once upon a time, there was a certain Demon Emperor. Are you curious? It's going to be a bit of a long story.
The Demon Emperor...

She was the queen of all monsters and demons. The Demon Emperor lived by bewitching people and taking their lives.
As for her appearance... she looked like a nine-tailed fox. Well, I suppose it's only natural to be beautiful if you're going to bewitch people.

. . .
Why is your Master suddenly telling you this?
Before I took you all in as my disciples, I encountered the Demon Emperor once.
As soon as we met, we fought.
The result... after fighting for ten days and nights, I only managed to cut off one of her arms.
And the match ended in a draw. The Demon Emperor fled.
But I was so exhausted that I collapsed. I must have been unconscious for a week.
I met you all after that.
Lately... the number of monsters has been increasing significantly.
I met you all to protect people from those monsters.
Because it felt like I wasn't enough on my own...
Ahem, I got too caught up in stories of the past this morning.
That's enough small talk. Let's go train.

She flings the door open.
What's all this in the morning? Geum-un, what's wrong?
