Nobody talks about this one. A Nepalese boy follows a crane into the Himalayas and finds a kingdom that feels like it exists in the margins of every adventure story you've seen, the place those heroes never actually visit. The animation moves like old watercolor, and the mystery of the letter pulls you forward without ever feeling like it owes you answers. This is a one-shot that knows exactly what it wants to be and doesn't stretch itself thin trying to be anything more.
Surya is a young Nepalese boy from a small village overlooking the Himalayas. One day a crane arrives carrying a letter, a heartfelt plea for help from a princess. Though he is far from the bravest of boys, Surya sets out to find the person who wrote it, and his search leads him to a mysterious kingdom in the mountains. Along the way, his adventures help him find the courage to carry out his mission. The story is told as a single-episode fantasy adventure OVA.
