I Quit the Hero’s Party

Once, there existed a group known as the Hero Party, tasked with defeating the Demon Lord to save the world. However, feeling frustrated by the Hero Party's reluctance to confront the Demon Lord directly, the Ashen Wizard Raniel decided to leave the Hero Party and returned to his hometown to reunite with his master. There, he was suggested for a role as an assistant professor at an esteemed academy. "Why are you so poor at this? Just create circuits, envelop yourself in mana, and utilize it." Yet, a prodigy like him appeared to lack any talent for instructing others. The mightiest of humanity embarks on his chaotic new role at the academy!
