Magic Academy’s Genius Blinker

Am I the worst character Baek Yu-seol?

Extreme difficulty, worst performance. In a world where everyone uses magic, Baek Yu-seol is the worst trash character of all time who is ignored because he cannot use magic. [Due to the wrong ending, 90% of Aether World was destroyed.] [Please reach the true ending.] I became possessed by White Yuseol. The only magic skill given to me is 'Blink'. I am the fastest wizard in the world. Survive at Stella Academy, a world filled with genius wizards!
