In the far future, Humans will be able to turn themselves into digital data.

People live in a metaverse called Crypton.

Crypton is a massive, ever-expanding metaverse built on top of many other metaverses. In here, people can be anything, but be cautious. There are numerous regions known as the dark zone that have yet to be explored. There's no guarantee you'll be able to find your way back if you get lost there.
