Withered Rose said to Amberser, "This is the fate of the Undead, isn't it? Never being satisfied, thus always tormented. Once desires are fulfilled, it's the time when Undead vanish completely. No matter what, I'm glad my last wish was about you. Now that I see you have been resurrected, I have no regrets anymore."
Once, Withered Rose only wanted to destroy the Laine Empire, but for countless years she was powerless, failing over and over. It was Amberser who helped her fulfill this wish, and at that time, Amberser became deeply bound to this desire for destruction.
When the Royal Family of Laine was completely doomed and the Laine Empire was on the verge of collapse, Withered Rose found herself unconsciously placing Amberser on an equally important pedestal.
Next, her desire turned to resurrecting Amberser.
