In a future where humanity has discovered parallel worlds, a mysterious profession known as World Designers emerges. By 2112, Earth has advanced to a point where these alternate realities are within reach. However, not all parallel worlds are stable; many are incomplete and face imminent destruction. The vital role of a World Designer is to project their soul into these troubled worlds, identify the key individual crucial to their existence, and help rebuild the protective barriers that safeguard them. Ton Tuyen is one of the interstellar's most senior and skilled World Designers. Her missions take her across diverse realms, from ancient martial arts worlds where demon cult leaders seek her life, to post-apocalyptic settings, fantastical immortal hero sagas, deep-sea horrors, haunted palaces, and even modern worlds on the brink of collapse. Each journey presents a new challenge, a new identity, and a new destiny to shape as she strives to prevent the demise of countless realities.
