Every century, the twelve astrological zodiac gods make their way down to Earth and procreate with mortals to bear one single offspring. Each offspring has special abilities associated with the four major elements that are related to each god, fire, earth, air, and water. Aries, the god of war and famine, begins to plot his reign over mankind to express his hatred toward humans for being the outcast among the Astrals. He uses his offspring, Axel, as his puppet to carry out his evil deeds until he is able to manifest and create chaos on Earth. Reina, the daughter of Virgo, and Asher, the son of Leo, work together to try and stop Axel from being completely corrupted by Aries' chaos. With the help of the researchers at the Astral Research Center, the rest of the offspring from around the world are brought together for the first time in history. Despite being only teenagers, the offspring are faced with the challenge of defeating Aries in order to save mankind and restore order between mortals and Astrals.
