~ Novel Ceros and Batozar is the 4th novel of the Earth series. It could be said that this novel is a spin-off before getting into the main conflict. Ceros and Batozar was published in May 2018 with 376 pages thick. Although still in the same series, the novels of Ceros and Batozar tell a story that tends to be different from before. This is because it no longer tells the story of the exploration of the three friends, namely Raib, Ali, and Seli in the Earth clan, Moon clan, or Sun clan. However, it tells the story of two different creatures that they had met on an adventure in a parallel world.

Ceros and Batozar are two different parts. Ceros are two giant creatures hiding below in a monument that is quite famous for its history. The two creatures were accidentally discovered by Ali, Raib, and Seli when their school was on a tour to one of the ancient sites, namely Bor-O-Bdur.

While Batozar is a criminal being from the moon clan who resides and hides in the Earth clan. The journey and adventure of Ali, Seli, and Raib this time will lead them to learn new fighting methods from Master B alias Batozar.
