Yuseol Baek

Baek Yuseol is the protagonist of the webnovel and manhwa series Magic Academy's Genius Blinker. He is a korean man who was a 10-year-veteran of the game Aether World and exclusively played as the trash character Baek Yuseol due to their identical name and appearance, and very unusual mechanics. After being the only player who managed to defeat the Demonic Black Dragon, he was transmigrated into the game world as his favourite character with the task of reaching the True Ending. He didn't know the details of the story of the game, because it didn't interest him, but he excelled on PvP content. His character, Baek Yuseol, was the only one in the game that couldn't use magic, due to his Mana Leakage Syndrome that would kill him in his youth, but it gave him a sixth sense perception and let him use and master the "Blink" spell, despite the many drawbacks.
