Synopsis:
The year is 2800 of the Midgard calendar. At that time, there was a Sovereign who ruled with absolute power and was about to subjugate the entire world. But her name was Lufasu Mafaalu, an imposing woman feared as the Sovereign of the Black Wings. She was too strong, too fast, and incredibly beautiful. However, she was defeated by Heroes who rose up against her ferocity, and thus, her ambition came to an end.
