Episode 1 – "The Spark"
[Opening Scene – NeoLuna Skyline, Night]
The city floats among the clouds, neon lights glittering like constellations. Steam vents hiss from skyship docks, and the hum of reactors blends with the faint whisper of wind across the skybridges.
On the rooftop of a small repair shop, KAITO HOSHIKAWA (19) works beneath a hanging lamp, sparks flying from the mechanical limb that replaces his left arm. His jacket is rolled up, revealing silver plating etched with old, faded symbols.
HARUTO HOSHIKAWA (10), barefoot and holding a tiny telescope, points toward the horizon.
> Haruto: "Kaito… the sky's… cracking."
Kaito laughs softly without looking up.
> Kaito: "You've been reading too many of Grandpa's ghost stories."
But then — the air trembles. A faint ringing, like a glass about to shatter, fills the night. A thin fracture of light slices across the distant sky, widening like a wound.

[Impact]
A burning shard streaks toward them. Kaito grabs Haruto and dives as it slams into the rooftop, sending tools clattering. The heat dies quickly, leaving behind a crystal fragment, humming with an alien pulse.
When Kaito picks it up, his prosthetic arm glows. Strange runes ignite along the plating.
Mariko Hoshikawa (40), their mother, bursts onto the roof. Her eyes widen — not at the damage, but at the shard itself.
> Mariko (quietly): "…It's begun."

[Cut to: Streets of NeoLuna]
Kaito walks with Haruto through neon-lit alleys toward Yume Arakawa's crystal shop. The bell chimes softly as they enter. Yume (19) stands behind the counter, tying up her dark hair, the workshop around her filled with shimmering glass and gemstone creations.
> Yume: "You brought me a meteor, or a bomb?"
Kaito (grinning): "Not sure yet. Thought you'd like the mystery."
They share easy banter, but when Yume touches the shard, it glows faintly in her palm. She looks at him — serious.
> Yume: "Kaito… this isn't from the sky we know."

[Night Attack]
Shadows ripple along the rooftops outside. From the fracture in the sky, inky creatures pour into NeoLuna, their bodies flickering like broken silhouettes.
Haruto's pocket begins to glow — the Little Star Stone he carries reacts violently to the shard in Kaito's arm.
Rina Hoshikawa (16) rushes in, her handheld device projecting holographic illusions to confuse the shadows.
> Rina: "Kaito, Mom said to get home now—"
A shadow lunges. Kaito's arm flares, releasing a blinding arc of light that slices the creature apart. He stares at his own hand in shock.

[Final Scene – Rooftop Again]
The family regroups at the workshop. Mariko says nothing, but in her eyes there's both fear and recognition.
From far above, the sky fracture grows wider.
Narrator (V.O.):
> "And so… the night the sky broke, the Hoshikawa family's fate began to turn — toward a battle written in the first stars."
