Nao

Nao (ナオ, Nao), alternatively known as Nao Zheng (ナオゼング, Nao Zengu), is the wife of Longwei Zheng, and prior to meeting him, a slave in Bosco, having spent the majority of her life as one. She was found by Longwei, heavily wounded for unspecified reasons, and was soon after under his care, and due to having no place to return to, moved to his household, until eventually marrying him after he proposed. Her past is mostly left ambigious, due to her own refusal to speak of it, much less speak in general.
