The Hungries are light combat operatives. Both Gakis and Pretas are likely trained using a reward-mediated trial-and-error system, expedited by the EI artificially stimulating their appetite centers. This might explain the Combined Army military designation for these creatures: ‘The Hungries’. Humans met them for the first time on Paradiso, where they codenamed them Gakis and Pretas, the Japanese and Hindi names for hungry ghosts, after their fierce attacks and their inclination to move in ravening packs.
