Although he was born into a ducal family, Kaizar is treated as worthless because he lacks talent for magic. Overshadowed by his brilliant younger brother and even scorned by his childhood friend and fiancée, Liliana, he endures one humiliating day after another. But everything changes when his memories return, and he realizes this world is the very VRMMO he once poured countless hours and money into in his past life. And when he opens his status window, he discovers that the save data from back then is still there. With his "Display Character Stats" setting activated, he resolves to get ruthless revenge on everyone who ever looked down on him.
