Defying the Divine Mech

In the ancient mythological era, the gods fell one after another during Ragnarök, but unwilling to accept the impending apocalypse, they commissioned Herstos and Chiyou to jointly forge the divine mecha 'Celestial Armament' as vessels for their souls. After its completion, Chiyou miniaturized these mechas and hid them in unknown corners of the Milky Way, awaiting the awakening of the gods in the mythological age.
