Synopsis
The narrative of "Nat-chan no Akai Tebukuro" centers on the atomic bombing of Hiroshima. A young girl named Nat-chan, having recently moved to Hiroshima, was knitting a pair of red mittens for her friend Shun-chan. She is killed when the bomb detonates. Many years later, an adult Shun-chan comes across Nat-chan's lingering presence through the nuclear shadow—the silhouette burned into the ground where her body was vaporized.
