On the planet Aya, death has been conquered.
Thanks to the "Regeneration" project, millions of people are returning to life-young, healthy, and with perfect memories. They have been granted a second chance. But what price must be paid for this miracle?Everyone knows Sophie as the ginger sunshine of Ikedor. Her laughter is contagious, her energy inexhaustible, and her kindness knows no bounds. She is the one who is always near to help, comfort, and arrange a party. But no one knows that her tireless optimism is the strongest armor, forged in the terrible old world.
When the past, which she has so diligently forgotten, begins to break through in bouts of inexplicable pain and panic, Sophie realizes she can no longer run. With the help of her friend Liza, she must open the locked door in her memory and relive that fateful day when a young girl was trampled by the cruelty of war.
This part reveals the biggest secret of the book-the origin story of the brightest soul in Ikedor. It is a story about how even the deepest wounds can be healed by love, and that true purification is the courage to look into one's own darkness to find the light within.
