The "Absolute Royals," proud and glorious, are the only ones who can offer this planet hope. The narrative describes the Kijuushi's daily lives. Laughter, sadness, pleasure, perplexity, and suffering would not deter them from their unwavering commitment to fighting. What are they fighting for? What are their options?
