Welcome, to this world of chaos and rebirth. Welcome to the Vortex World. The Vortex World-where the story of the original video game Shin Megami Tensei: Nocturne unfolded-was born after the Conception, an event devised by a man named Hikawa, a leader in the cult known as the Ring of Gaia. It is a world teeming with gods, fairies, and other creatures, all of them summarized with a single word: demon. Whether chance, whether destiny... Whether desired or not, those who remained after the Conception were forced into a life of survival. Some took in a Magatama and became a fiend. Others chose to cling to their humanity, remaining as a human. And some poor souls could not continue without borrowing from the strength of demons. In this game, you will take on the role of a human, fiend, or demon who wanders this Vortex World, and you will be swept up into matters that could happen only in a world such as this. Behold the Vortex World, the egg of the new world. Behold the war, waged between the Assembly of Nihilo and the Mantra Army. And know that to survive the strife of the Vortex World, you will need to unravel its mysteries. Shin Megami Tensei: The Roleplaying Game - Tokyo Conception is an isekai action-adventure TRPG reproduces the world of Nocturne for you to enjoy.
