Sakuya, Tobias and Mary explore the online world of The World R:X together, treating its quests as an escape from ordinary school life. A difficult expedition goes awry, and Sakuya encounters Hermit, a mysterious catlike player whose presence unsettles their familiar game.

When the consequences begin reaching beyond the screen, the friends can no longer treat what happens to their characters as harmless play. Searching for answers draws them into hidden dangers within the game and a struggle in which their real lives are at stake.
