Traveling Around with a Sword

If the world is unfair, then justice will be created. If the world is not benevolent, then create benevolence and righteousness. If the world is dishonest, then honesty will be created. Although there is a sun in my world, there is darkness everywhere. Until one day, the only sun also died... I want to cry and forget the darkest moment, but my brother cannot have tears. I want to go back to the past and change the ending, but even the Creation God Emperor can't do it. I want to grow up and become a brother like my sister, but after traveling through the world countless times, I don't even understand the human heart. A sword, a bow, and a song of separation. Traveling around the city with a sword.
