The work is about a girl named "Kaname Kaede" who can only survive by relying on life-support equipment. She has lost her freedom in the real world and can only explore in the VRMMORPG "Riad". She lost her life in an accident when the equipment stopped working, but unexpectedly she was reincarnated in "Riad" 200 years later. She will travel in the new world as a high elf "Aina" and try to investigate the events that happened during the 200-year blank period.
