Well, in context, I guess it should be something like:
"Now you've done it! You've beaten me!
I was beaten by your ancestors as well.
That's why I was sealed in this world.
If I'd have beaten you, I'd be free now.
But it's too early to relax just yet.
Justice doesn't always prevail, you see,
for when things are broken,
they turn into Gunties(?).
You have a Gunty(?) in your heart."
I'm not sure what a "Gunty" is. I think I might've heard the term when I helped out with this translation a while ago, but I can't remember now.
