Yasei no Last Boss ga Arawareta!

It was in the year 2800 of the Midgard calendar. Back then, there was a Overlord who once reigned supreme and had reached the very brink of subduing the world. Her name was Lufasu Mafaalu, a great woman dreaded as the Black-Winged Overlord. She was too strong, too fast, and too beautiful. However, she was defeated by Heroes who opposed her ferocity, and her ambition was brought to an end.
