One word: incredible! It takes place in Hiroshima during the war. I'm not a fan of anime at all but I think this anime will always hold a special place forever. The story was fast-moving and it's not too preachy. I thought it was written about our imagination. You know, the war only brought sorrow and took our imagination away. I actually was moved to tears sometimes since I empathized with her. I'm sure you'll be moved too :)
