The Daichis are far from a model family: money grubbing mom Seiko longs for excitement and is ready to divorce dad Mamoru, who's too nerdy and wimpy to stand up for himself. Sister Nozomi takes care of all the housekeeping as her parents carry out their drama, and little brother Dai just watches in confusion. Things don't look good for the future of the Daichis, until they're recruited by Galaxy Federation to help fight evil aliens. Now a family that could barely save themselves is saving the world -- and they might even save their family while they're at it.
