Agramant commands the Jadou Clan in its quest to conquer the universe by reviving the Great Lord of Darkness. He directs key subordinates—Dr. Bible, Enuma, and Nabu—against the Long-Ear Tribe and their defenders. A critical revelation later exposes Agramant as V-Ramas, grandfather of Rabi, one of the three Madou Warriors. This confirms his origins within the Long-Ear Tribe before the Jadou Empire corrupted him, transforming him into the Jadou's malevolent leader. This truth delivers profound shock and turmoil to Rabi and allies like Shaman.

To achieve his ultimate goal, Agramant forcibly brainwashes Rabi, seeking to exploit the young warrior's innate power to fully reawaken the Great Lord of Darkness. He then deploys Rabi against the remaining Madou Warriors, Daichi and Gus. The brainwashing is only shattered when the Black Warrior—revealed as Sayuri, Rabi's mother—attacks Agramant from within the Great Lord's confines.

Agramant's singular ambition remains the resurrection and control of the Great Lord of Darkness, intending to wield its power to dominate all realms. His strategies involve deploying Jadou Gods, later merging them into more powerful but pilot-straining Jadou Kings. The final conflict centers on this apocalyptic resurrection attempt within Rabiluna's core regions.
