The world of Sword Art Online (SAO) is one where a selected few people were arbitrarily trapped in a popular VR video game, where if you die in the game you die in real life. The bodies of the people trapped here are kept alive and they have no risk of dying from outside causes. Since being trapped, a society has formed around the tower that allows people to live a life in the virtual world. However, there is no way to contact the outside world and see the people outside the game. There only way to escape the game is to clear a 100 floor tower, filled with monsters and dangerous bosses. These floors can be cleared with other players trapped within the game, but there is no risk of the monsters escaping.

Some of Just Stop Oil's objectives include demanding the UK Government stop licensing any new oil, coal and gas projects in the country.
