Patapata Hikousen no Bouken

In a world where the past and present collide, a young girl named Jane embarks on a perilous journey to uncover the truth about her missing brother's fate. Born without a mother, Jane's life is forever changed when her father, a wealthy English aristocrat, remarries and brings home a stepbrother, William, who harbors a deep-seated resentment towards his new family. As they grow up together, George, Jane's father, and her brother William share a childhood dream of building a flying machine. George's obsession with a mystical, blue-hued sand from the distant Asian deserts convinces him that this enigmatic substance holds the key to making their dream a reality. Believing that this sand can defy gravity and make machines take to the skies, George sets out on an expedition to find it, only to be declared executed for treason. Meanwhile, William vanishes without a word. A cryptic, unsigned letter bearing a handful of pale-blue sand that seems to defy gravity arrives at Jane's doorstep, setting her on a quest to find her brother and clear his name. Joined by a cast of new friends, Jane's journey takes her to the farthest reaches of the East, where ancient mysteries and hidden secrets await. As she navigates treacherous landscapes and uncovers hidden truths, Jane begins to realize that some secrets may be destined to remain forever buried in the sands of time.
