After Elfin overhears Preyas talking down about her receiving the energy and rash behavior, Elfin runs off into the city and encounters Shadow Prove and Hydron. Marucho and Preyas arrive in time to rescue her and a battle ensues. At first, Elfin and Preyas have trouble getting along but they put their differences aside and almost defeat the Vexos, but Elfin shields Preyas from an attack and therefore loses the Aquos energy.
