A young man's passion turns to a fantasy epic. There are no real evil people in Kyushu. The rebellion of the demons was caused by the influence and bewitchment of the thoughts of the evil tribes outside the territory. After the war, everything was cleared and reconciled. The only mortal enemy in the book is the evil tribe of the void outside the territory. With the rise of the twins of the human race, all races put aside their estrangements and jointly resist the invasion from outside the territory. The ending is tragic, requiring huge sacrifices, and not a happy reunion for everyone.
