The "Angel" had completely become a legend. She could no longer enter the Upper City District with a halo, nor dare reveal her identity as an Angel in the Lower City District...
After the loss of her parents' protection, the eleven-year-old Paradise Bird relied on her intelligence, far beyond that of ordinary people, to struggle for survival in the Lower City District as a Codeless.
Her family had once joined a small mutual aid organization called "Cave House". Before her mother's death, she also entrusted her old friend to take care of Paradise Bird.
There, she was very happy, as if she had a home for the second time.
Her parents' old friend was also a good person. Although life was impoverished, it was joyful... Her Healing Ability was a help to others.
She had hoped to maintain such a stable life, to live a secure and happy existence... even if she never saw the bright sunlight again, it wouldn't matter.
