Infinite Dendrogram

In 2043, a groundbreaking full-dive VRMMO called Infinite Dendrogram is launched, offering a fully immersive experience with realistic sensory simulation and a range of advanced features. Two years later, Reiji Mukudori, a high school graduate about to start college, purchases the game and begins playing. With assistance from his older brother, Shu, and a companion named Embryo, Reiji enters the game's world. The game is known for its high level of realism and the promise of limitless possibilities. As he explores, Reiji encounters various experiences and challenges within this expansive virtual environment.
