Amazon’s listing of the 14th volume of Midori Amagaeru and Kyokatsukasa’s Online: The Comic manga states that the manga is approaching its climax and will end in the 15th volume.
The game she is forced to play, “Nightmare,” is a dangerous game in which one risks both the lives of the ones they love and their own body!!
The horror of this game spreads throughout society in a flash, and, to fight it, Mai’s company creates a “Nightmare” Strategy Team.
If you lose battles in the game, parts of your body (your arms or legs, your voice, etc.) cease functioning.
