Kōga is worried over the disappearance of Athena and frustrated for his failure to protect her and his mentor Shaina. Kōga is determined to master his Cosmo to rescue his goddess. Kōga departs to improve his mastery over Cosmo, later meeting Sōma, the Lionet Bronze Saint, who teaches him about the elements of Cosmo. Eventually, Kōga and Sōma are greeted by the challenge of Mantis Ordykia, one of Mars' henchmen, who puts their command over Cosmo to the test, an experience that strengthens their newfound friendship.
