Blink Master of the Magic Academy

The character with the highest difficulty and the worst performance, Baek Yuseol, was considered a trash character in-game because he could not use magic in a fantasy setting where everyone else could. However... [Because the wrong ending has been reached, 90% of Aether World has been destroyed.] [Please reach the "True Ending."] Suddenly, those words echoed in my mind before I was transmigrated to the Aether World. [You can use the skill "Blink."] "Just why did I possess this character?" Blink was the only magic skill I had. Surviving in Stella Academy among genius mages, I became the notorious Blink Mage.
