Mori, a silent child discovered in the wreckage of an abandoned home, has spent his early years tucked away in a protection center while the world around him is ruled by ancient, advanced alien beings. Also known as *On the Way to See My Mom*, this stirring tale truly begins the day Mori watches his only friend vanish into the embrace of a long-lost mother, sparking a realization that he, too, has a parent waiting for him somewhere in the vast unknown. Clutching a bag of small treasures and a heart full of courage, he escapes the facility and hitches a ride on a departing train, setting out on a lonely and dangerous quest to find the woman who has been sending him secret care packages from across the stars.

The journey proves to be a grueling test of spirit as Mori navigates a landscape where humans are often seen as nothing more than prey for roaming demons and the cold logic of galactic overlords. A fateful encounter with a hardened bounty hunter named Rider and a mysterious, high-ranking alien named Miria transforms his mission, as these unlikely guardians find themselves drawn to the boy's unwavering innocence in a universe that has long forgotten the meaning of warmth. Caught between the physical dangers of a hostile wilderness and the internal struggle to find his own voice in a galaxy that doesn't understand him, Mori refuses to let his spirit break. He remains driven by one singular, radiant dream: to bridge the gap between human and alien worlds and finally find a place where he truly belongs in the arms of his mother.
