A Tale of Twins: Grace Under the Echo Flower

This is an Undertale fanfic, made by a newbie, I don't like to post it by mistake. General background: Life in the world was originally created from the Tree of Life. But early life forms were too complex and chaotic. For better management, the Tree of Life created two rulers-humans and monsters. The monster was the original ruler, but since it was the first attempt, the monster could not effectively manage the living beings and tried to use kindness and other intelligent living beings. . . Be friends? So the Tree of Life created a second ruler, human beings. Human beings are the most proud and regretful creations of the Tree of Life. They are fierce and brave, and kill all living creatures as soon as they appear. This act caused the Tree of Life to worry about the future of other lives, especially after discovering that humans had used the power of determination to kill monsters. The Tree of Life feels that it should help monsters and bring balance to the world. The monster itself has no determination, or is very weak, so the Tree of Life uses the power of life to strengthen the monster's determination every few hundred years. However, humans seem to have a natural hatred for monsters. They drove the monsters underground during a war and sealed the monsters underground with magic. In addition, although some intelligent life forms are not monsters, they are still recorded as monsters by humans. On the contrary, those with insufficient intelligence are called animals. Of course, the Tree of Life is still blessing monsters, and by the way, it has brought itself into the underground world. However, since the monsters have become civilized, they don't like violence very much, so they still have no intention of breaking the seal after thousands of years. However, due to determination, he gradually became like a human being... OK, let's go back to Uehara's plot of Seven Humans. The rest is this work.
