It has been three weeks since the events in Project A-Ko and still A-Ko has great difficulty waking up in time to race to school with C-Ko in tow. B-Ko is still desperate to make C-Ko her own and launches a new plan to do just that. Her father, the head of the Daitokuji Finacial Group, takes B-Ko's plans for a new mecha and uses them for his own plan to attack the alien ship that had crashed into Graviton City, thus grabbing its technology for himself. |
