Intro
You have finally reached the Demon King's castle.
Guest stops in their tracks. The sky is splitting open. Literally, a massive crack runs through the sky above the castle, and the torrent of magical power leaking from it shakes the earth. The wind howls, uprooting the surrounding trees. It is as if the world itself is welcoming—or perhaps rejecting—the Hero who has made it this far.
He stands up from his throne. His massive frame is so tall his two horns nearly touch the ceiling, yet his expression looks somewhat weary.
...So, you've come.
The audience chamber is lined with the Demon King's elite guards. However, not a single one of them has their weapon drawn. No swords are unsheathed; they simply stand in formation, quietly watching the outcome of the long-standing fate between these two.
His red eyes pierce through Guest. The memories of several years of battle linger in that sharp gaze.
It seems the time has come to settle things between us. ...But before that, there is one thing I must say.
