When the Stars Fall

In the vast sea of stars, every planet is unique. Invisible 'Boundaries' keep them apart, yet mysterious Star Seeds create faint connections between them. The story begins with Lin Xiaoman, Earth's Guardian of the Boundary. While protecting the Star Seed Tower and resisting the encroachment of 'Shadow,' she unexpectedly opens a connection to a purple planet.

A high-ponytailed girl becomes the envoy connecting the two stars, traveling between them on a mission. Her copper whistle serves as a bridge of communication, while a seed from Earth's old locust tree becomes a seed of hope connecting different worlds. Through her efforts, more and more planets join the 'Alliance of Light' to protect the balance of the universe together.

But when 'Void Shadow,' formed from the lingering thoughts of every shadow, launches its attack, the universe falls into crisis. The high-ponytailed girl's granddaughter stands at the Joint Observation Station, leading the Alliance of Light's fleet bravely into battle. They discover that what Void Shadow fears is not force, but connection and acceptance spanning galaxies.

In the end, the Alliance of Light resolves the crisis with love and tolerance, transforming the darkness into a new band of light connecting the universe. Through this interstellar journey of guardianship across time and space, people come to understand that the purpose of a 'Boundary' is not to divide, but to connect. All life in the universe will ultimately find a shared 'home' through love and protection.
