Keina Kagami was injured in an accident so badly that she could not survive without being hooked up to life-support machines. One day, those life-support machines stop functioning and she loses her life. When she wakes up, she's in the world of the VRMMORPG "Leadale," and in the form of her avatar, Cayna. But something seemed a bit different than the game world she was used to...

così tanti giocatori...
Meu passado sombrio, de quando
passei por cima de outros jogadores...
