To support himself, he worked in a bakery, using his earnings to cover his daily needs and indulge in his favorite pastime—reading chapters of the novel “Humanity's Strongest Mage,” which had recently gone on hiatus.Eric had a love-hate relationship with the novel. While he was captivated by its world, he despised the Protagonist, Alex Whiteheart. Alex had it all from the start: strength, fame, money, and of course, a harem. He never faced any real challenges, effortlessly overcoming every obstacle, which made the story lack something Eric craved....... Chaos.One evening, while taking a walk with his headphones on, Eric was lost in thought. The music drowned out the world around him, and he failed to notice a car losing control and speeding toward him. The last thing he heard was a screech before everything went dark.When Eric woke up, memories flooded his mind, and he quickly realized something was wrong.

He was determined to introduce Chaos into the story, making it far more interesting than it ever was, and in the process, he'll also find out that there's more to his character than just being an Extra.Let the Chaos begin!
