Wake up!! Tamala  

In 2050, the world's climate has worsened significantly. On a rainy day, Tamala rescues a honeybee named Kuronosuke from drowning in a gutter. As the last bee of his kind, he invites Tamala on a magical journey through time-back to our near future. However, as her era approaches quickly, she witnesses civilization's destruction and degradation of nature. She roams around a land where all other animals are extinct and eventually begins to starve. Kuronosuke then offers himself as food to Tamala.
