The Returned Former Hero Dominates in VRMMO. ~A Life Aiming to Support His Vtuber Little Sister to the Fullest~

The reason for returning to Earth? To pamper his little sister? One day, I was suddenly summoned to another world and successfully fulfilled my role as a hero within a year, then returned to Japan. I safely reunited with my little sister, all’s well that ends well… or so I thought. To my surprise, my little sister had become a VTuber! Not only that, she was the promotional manager for the popular VRMMO “Little Brave Online” that was garnering attention worldwide! To contribute items to my sister, I promptly purchased “Little Brave Online” and started playing. In that world, where levels and stats matter, one’s skill is paramount above all else. While many struggle in battles with swords and magic, having already experienced them, I effortlessly dominate with the fastest conquests, contributing items to my sister along the way! This is the story of how I support my sister.
