In the vast forests, towering mountains, and the wide seas, mythical creatures spread across the wide world. Some are large and terrifying, while others are small and gentle; half of them enjoy harming humans, while others wish to help them.No one knows exactly when they appeared. Some say they existed before the human race emerged, while others claim they appeared alongside the first humans in this world.Their forms and abilities vary, and different races deal with them differently. Some despise them and consider them monsters, while others revere them. Yet everyone agrees on one thing: it is best not to attempt to meddle with them.Everyone, that is, except for one person.

Setsuna Shū is a magical girl with temporal magic that allows her to go back to the past whenever she performs a certain action. She works as a magical girl, hunting monsters and helping people… or at least, that’s what she lets everyone believe. In truth, she made a contract with a demon so she could return to the past and rewrite the future.Her real reason for turning back time is to save her “sister.” As a child, she had no parents, relatives, or friends. When she was finally adopted, her sister became her entire world — and for her sake, Setsuna wouldn’t hesitate to sacrifice the world itself. She gave up her original gender, her past “existence,” and even parts of her freedom in a demonic contract, all for the sake of saving her sister and taking revenge on the monsters that hurt her.But… is that really all there is to it? Or is Setsuna, in the end, partially responsible for everything that happened?

Go back to 2000.

Lin Feng didn’t want to disturb the situation, he just wanted to protect the things he cherished.

However, there is no need to explain the open life.

Since it’s all over again, there’s no turning back when you open the bow!
