Shiro Sora (しろ そら, lit. White Sky) is a young Genin of thirteen years old. A social recluse at heart, she often exiles herself to the various bookstores and libraries of konoha to "do research". Her inability to speak and pensive nature conceal a hidden identity, however. Young Shiro is a famous mangaka with thousands of adoring fans the country over. Using her anonymous alias, Blank (くうはく), she submits overwhelmingly popular visual novels and manga. To date, she has accumulated billions of Ryo. In spite of her fortune, she seems content to live the life of a genin, and continues her ninja training for unknown reasons.
