A Wild Last Boss Appeared!
An MMO gamer awakens as the Black-Winged Tyrant, Lufas Maphaahl, rising from her sealed fate—only to find this is very real.

Now, trapped in the body of history’s most feared conqueror, he must survive a world that wants her dead…and uncover why he’s here. (Source: Crunchyroll)
