Leadale no Daichi nite

Due to a terrible accident, Keina Kagami was placed on a ventilator. Her only space of freedom is the VRMMORPG Leadale. One day, the machine keeping her alive stops working and Keina passes away. But when she wakes up, she finds herself in the world of Leadale, 200 years in the future. She is now embodied as the half-elf Cayna and possesses forgotten skills and statuses. She then grows closer to the other inhabitants of this world, especially the children she had created at the same time as her character.
