| The Chief of Staff of the Holy Harmonia Kingdom's regular army. He leads the army and supports Bishop Sasarai.
— Dios' profile
Dios is a military officer within the Harmonian army and the aide-de-camp of Bishop Sasarai. He's considered to be quite clever but due to bad luck and a lack of social skills he always seems to be assigned to thankless support roles. As such, he was never evaluated particularly highly within the military until his performance in the Higheast Rebellion caught the eye of Sasarai, earning him a promotion to Chief of Staff under his command.
Due to Sasarai's faith in him, Dios has felt a strong obligation to his commanding officer. During the War of the Champions, he always stood beside Sasarai, even after Luc turned on him forcing them into the arms of the Fire Bringer, despite his lack of martial prowess. Following the war, he continued to serve under Sasarai, supporting him both publicly and behind the scenes.
