Throughout his existence, Shiki has lived amid machinery. In the Granbell Kingdom, a once‑abandoned amusement park, he is the sole survivor of his species. That changes when Rebecca Bluegarden and her cat Happy arrive, oblivious to the fact that they are the first visitors in a century. Their mission is to film entertaining clips for their B‑Cube channel, yet they discover instead a companion in the shy Shiki.
When Granbell turns too perilous for the trio, they embark on a journey across the Sakura Cosmos. They aim to capture more captivating footage and locate the mysterious goddess Mother, while Shiki yearns for companionship inspired by his late grandfather"s counsel. Naturally the expedition is fraught with difficulty, as Mother has never been witnessed, but Shiki remains resolute to achieve his aim and explore the infinite expanse of space alongside his newfound allies through the endless reaches of the universe and share unforgettable adventures with them together today.
