A sea otter and his friends, a raccoon and squirrel, live and play together in the forest.

Five years ago, something horrifying happened on Kamioki Island. Something so nightmarish that it stripped all memory from Mari Wakatake's mind even as it left every other human on the island dead in its wake! Now enrolled against her will at an isolated girl's academy, Mari is unaware that hidden eyes are watching her, waiting for her memory to return. Buried in her psyche is the most terrifying secret of all: while Mari was the only human who lived, she may not have been the only survivor! As something in a female skin invades Kaihou Academy, Mari's only hope may lie in a strange girl to whom she is inexplicably drawn yet cannot trust. (Source: Sentai Filmworks)

Above a nondescript kitchen counter quietly hangs a bunch of ripe, yellow bananas. Suddenly, one of the slender fruits begins to shake, gently at first but slowly increasing in ferocity until it tears itself away from the rest. With a graceful landing, the long and curvy edible gradually rolls back its golden peels, revealing what lies beneath its firm covering to be... a cat? This mysterious feline-fruit hybrid is named Bananya. Carefree and gentle, the adorable creature dreams of one day becoming a luscious bananya bathed in chocolate. Together with his fellow bananya, this kitten cloaked in yellow passes its days without a care in the world, enjoying a rather calm and peaceful existence as it experiences what the world has to offer.
