Moid, whose full name is Balance T. Moid, is the primary antagonist of the series. He is stationed on the offshore base Pharos and initially presents himself as a mysterious but superficially polite man working alongside the military organization Novumundus. Beneath this calm exterior, he harbors a deep obsession with the Rin‑ne, the enigmatic flower that lies at the heart of the story. His true nature is revealed late in the narrative: he was the one who caused the destruction of Earth twenty thousand years ago by opening the Rin‑ne, and in the present, he schemes to repeat that cataclysm.

His personality is marked by a quiet, almost gentlemanly demeanor, though his actions betray a ruthless and calculating mind. He displays eccentric habits, such as enjoying pudding a la mode mixed into a soup before eating. As a mad scientist figure, he is driven not by malice for its own sake but by an aesthetic fascination with the beauty of the Rin‑ne; he is willing to bring about the apocalypse simply to witness that beauty unfold.

Moid’s role in the story is that of a treacherous advisor. He manipulates the conflict between the planets Le Garite and De Metrio, using both sides as pawns in his larger plan. His key relationships are defined by this manipulation: he positions himself as a helpful figure on Pharos, yet he ultimately betrays those who trust him. His development is one of gradual revelation; for much of the series he appears to be a benign supporting character, only to be unmasked as the true architect of the crisis.

Notable abilities include his extensive knowledge of the Rin‑ne and its properties, as well as his skill in long‑term scheming and psychological manipulation. He does not rely on physical combat but rather on cunning and the exploitation of others’ ambitions. In the season two finale, he attempts to destroy Earth once more by forcing open the Rin‑ne, cementing his role as a calculating and relentless antagonist.
