Warm 3D animated cartoon, anime-inspired, vibrant colours, smooth natural animation and expressive movement. At sunset in a fictional Pakistani town surrounded by lush green hills and an old forest, 14-year-old Ren, a quiet protective boy with an older-brother demeanor, walks home with his 11-year-old sister Yui, a cheerful, curious girl carrying her drawing. They reach a small bridge as orange sunset light fades into blue twilight. Yui suddenly stops and listens. Leaves rustle in the forest, and a faint mysterious humming fills the air. A tiny glowing blue light slips between the dark trees. Yui points toward it, eyes wide with wonder, while Ren instinctively takes her hand and steps protectively in front of her. The camera slowly pushes toward the forest as the blue light flickers mysteriously among the trees. YUI whispers, "There." The scene ends with the siblings hurrying away as the distant hills and forest fall into deepening twilight.
