After transmigrating as Yagami Taichi, he even has a cute little sister!
It's just that the story has taken a rather chaotic turn. The Hikarigaoka Incident never happened, and the Digital World is shrouded in darkness.
Time and space overlap, and darkness invades.
To protect his sister, Yagami Taichi gradually sets out on the path to becoming the strongest, and along the way, saving the Digital World.
