S1.E3 ∙ A Battle Between Two Evils

A-ko and B-ko are fighting as usual, as C-ko watches from the sidelines feeling neglected by both. Ayumi-sensei has been behaving strangely lately. She's wearing a heart-shaped crystal with a hexagram inside, and is chanting mysterious prayers in private. At the ruins of an ancient civilization, an archaeologist spies a hexagram among the hieroglyphics. Deep in outer space, an alien fleet is on a course for Earth, and its flagship bears the same hexagram shape.

It's summer in Graviton City, and the girls all have a break from school! A-Ko decides to lose a few inches, C-Ko makes a list of all the cool things that she'll buy, and B-Ko vows to get A-Ko out of the way once and for all so that she can have C-Ko to herself. To this end, she designs a new giant mecha, better than all the others. But her father steals her designs and uses them to attack the crashed alien spacecraft (now high-class restaurant) in an attempt to steal the advanced technology of the aliens.

Taka(Tamahome) and Miaka has started their lives as a married couple. While waiting for their child to be born, Tamahome and Miaka are faced with a new challenge. A new girl entered the world of the four Gods determined to make Taka hers.

It revolves around A-Ko and B-ko's pursuit of a handsome stud named Kay. He likes coke and motorcycles and is quietly courted by both A-ko and B-ko. Meanwhile, C-ko grows very jealous of him.. Also meanwhile, the aliens' ship in now floating in the bay and they've tried again to turn it into the ultimate nightspot. Good luck. Catastrophe always occurs when the three 'Ko's get together.
