lord dearche

One of the antagonists of Mahou Shoujo Lyrical Nanoha A's Portable: The Battle of Aces. Material-D, also known as King Ruler over Darkness and Lord Dearche is a "dark copy" of Yagami Hayate. She wields Yersiniakreuz, a copy of Hayate's Schwertkreuz, and the Tome of the Purple Sky, a copy of Hayate's Tome of the Night Sky.

In Mahou Shoujo Lyrical Nanoha INNOCENT, she is known as Dearche Kings Claudia and her resemblance to Hayate is merely coincidental.
