Oseam

They both tell the story of sibling love, the innocence of children and their games and the often tragic lives of orphans. While Grave of the fireflies is based on facts of the lives of war children, Oseam is based on a legend/fairy tale. Oseam doesn't have the feeling of a brutal reality as Grave of the fireflies and has a more religious tone in the story using the ideas and believes of Buddhism.
Simply put, they both are beautiful and tragic stories, and if you like the one, you'll definitely like the other
