It's Getting Dark and I'm Getting Stronger

One hundred years have passed, two hundred years have passed. . . . After 1000. People woke up together as if they had agreed. The cities of the past have long been replaced by forests. There are many bizarre things in the woods, but there are many strange places in them, which indicate the changes in the world. Only some people have dark green pupils. They have many abilities and all sorts of strange things. The sky is full of stars, but many black holes appear. Only those who are able can enter it.
