Yasei no Last Boss ga Arawareta!

Two hundred years ago, the black-winged Lufas Maphaahl was the greatest conqueror in Exgate until seven heroes defeated her in what the player behind her avatar thought was simply a spectacular in-game event. A strange message later pulls him into the world, where he awakens inside Lufas herself and discovers that Exgate is now real.

Two centuries have passed, monsters spread beneath the Devil King's shadow, and Lufas's name has become a legend of terror. She now travels to find her former followers, the Twelve Heavenly Stars, and uncover why she was summoned, all while the world reacts to her as a tyrant returned from the dead.
