I Became a Flashing Genius at the Magic Academy

'''Infernal difficulty, the worst performance. In a world where everyone uses magic, I'm the worst trash character, Baek Yuseol, discarded even by the most hardcore players for being unable to use magic. But… [You have reached a bad ending, resulting in the destruction of 90% of the Aether World.] [Please reach the true ending.] Why did I become Baek Yuseol? [You can use the skill ‘Blink Forward’.] Blink, the only magic skill given to me. Survive in Stella Academy, overflowing with genius mages! I am the fastest mage in the world.'''
