FF14 players were on a mission to help the Sages of Dawn test the technology of separating souls and memories newly developed by Gulahatia in order to return to Eorzea through the gap in time and space. When they were wearing a game shell, they traveled to a new world, broke the crystal that stored memories, and ran around to retrieve the memories.
Past life memories are blurred due to the aftereffects of time travel, and game memories can be slowly retrieved through crystals
The heroine is an all-professional boss, and her race is the female Laraphil clan, which in layman's terms is a dwarf. She doesn't grow up. There is absolutely no difference between an 8-year-old and an 80-year-old. Her age cannot be judged from her appearance. In the later stages, she can use fantasy medicine to change her race/change her vest with one click.
Remember, as long as the heroine is strong and invincible, it's all good. After all, Kezi is the chosen one. He is skilled in both magic and martial arts. He kills gods to save the world on a daily basis, and he has a great background.
Try to write in a way that you can understand without playing the game.
Concept: The heroine's mission is to save the world! Positive energy!
