Rain's understanding of the sea dragons' technique made him think that it was similar if compared to the leviathan dragons. Both techniques involved storing and harnessing energy, which was then utilized during combat to enhance the dragon's abilities. However, there was a fundamental difference between the two approaches.
Unlike the leviathan dragons, who could grow to massive sizes and turn the energy into parameters, the sea dragons used their stored energy more efficiently. Rather than growing in size, they conserved their energy for the next combat encounter, making them more adaptable for shorter but intense bursts of power. Initially, Rain thought this distinction would make it easier for him to learn the sea dragon technique, but he quickly realized that it was far more challenging than he had anticipated.
