The Orbital Children

Born on the moon, Toya half-heartedly welcomes three kids from Earth to his home in space. But during the welcome party a terrifying accident occurs.

Toya and Taiyo make their way through the station to find their friends after the shockwave from the passing comet knocks out oxygen and the internet.

The rabbit mascot comes to aid the children, who are trapped in a room leaking air. But to escape, the kids must walk outside in space to reach a ship.
