"You should be careful," Midnight Duchess told Rever with her signature chilling tone. 

 

The recent skirmish with the menacing skeletons had narrowly spared him from an untimely demise thanks to Midnight Duchess's timely intervention.

 

But instead of offering gratitude, Rever was ecstatic. He couldn't contain his awe as he exclaimed, "Whoa! You're alive?! You're truly immortal!"

 

A subtle arch of Midnight Duchess's brow conveyed her bemusement. "Of course, I'm alive. To whom do you think you speak?" 

 

Even without the help of the mysterious woman, she could still get out from there alive with her life-saving item. But she thanks her nevertheless. 

 

With her intervention she got to keep her precious items.
