A kind of power appeared on an unknown planet. Its name is magic. Magic cannot be detected by ordinary people. Only those with talents can use it. Among those with talents, generally only girls aged 13 to 17 can exert its most powerful power. While magic gives humans power, it also brings despair to humans. A kind of monster-beast is created by the fusion of twisted emotions and magic in the human mind. They hunt humans without any scruples when ordinary people cannot see, touch, or fight back.
At this time, the magical girls stepped forward. They shouldered the responsibilities that should not be theirs with the bodies of girls. The girls paid a heavy price. The former magical girls are now out of ten, and the beasts are finally isolated from Dawn City, the last super city of mankind. However, humans have no strength to take a step beyond the magic protection barrier. There are even beasts that often take advantage of the void or are born in the city. Humanity once fell into a desperate situation. It wasn't until that day that the scientific expedition team opened a frozen warehouse from a thousand years ago, and a girl in a witch costume appeared, and mankind saw the light of day.
