Infinite Dendrogram

In 2043, a virtual reality online game called Infinite Dendrogram launches, offering full sensory immersion and a highly realistic experience. Two years later, Reiji Mukudori, a high school graduate, purchases the game and begins playing. With assistance from his older brother, Shu, and a companion named Embryo, Reiji explores the game's expansive world. The game is known for its advanced simulation and limitless scenarios, and Reiji's journey within it remains uncertain.
