Yasei no Last Boss ga Arawareta!

It was in the year 2800 of the Midgard calendar. Back then, there was an 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.
