So Demon Lord, care to tell me why your speech is all broken?

Back in the other world your words were smooth as silk.

Also, you're way too close.

That world is one language.

And I made it so Hero could speak.

So you're saying I was speaking another language without realizing it?

That correct! Hero, I am happy you understand!

With the dark magic

I can do same thing here.

Make my speech into perfect Japanese

But I do not.

Wha? Why not?
