Moto Sekai 1-i no Sub Chara Ikusei Nikki: Hai Player, Isekai wo Kouryaku-chuu!

For the protagonist, video games were never merely a pastime—they were his entire reason for being. Having rarely shown his face at school throughout middle and high school, he drifted into adulthood without employment, devoting every hour from morning until night to the games he loved. His dedication paid off in spectacular fashion: he rose to become the number one ranked player in the entire world. Then disaster struck without warning. His prized character was suddenly hacked, and its data proved irretrievably lost—nothing could be done to restore it. Consumed by despair over the destruction of the rank he had staked everything to achieve in the virtual world that governed his life, the protagonist attempted to take his own life. When he next opened his eyes, he found himself inside the game—or so it first appeared. In truth, he had awakened in a genuine reality that closely resembled it, and he soon realized he had been reborn in the body of a sub character: one he had created long ago, outfitted with premium benefits he had purchased, and then abandoned to years of neglect.
