Synopsis：Once mocked as a worthless orphan, Cross awakened only a useless F‑rank Titan and was cast out by everyone… until the Titan System activated. He awakened the apocalyptic beasts Nidhogg and Fenrir and gained Devour—growing stronger by consuming every foe. Now his former bullies return to provoke him, and the demon legions invade the world. From total trash to 3S supreme genius—can this fallen loser rise to seize the Titan God throne?
