Gurafia

"Robe of Void Darkness" Graffia ( ヴォイド死闇ローブ ( グラフィア ), Voido Shi Yami Rōbu ( Gurafia )) is one of the Malebranche who rebelled against the True Demon Lord. He has a quiet personality and doesn't interact even with his colleagues.

Graffia took over the body of Deus Trinity, giving him enormous power. But this came with price of destroying his personality, turning him into an empty shell who only follow orders. Albalisha used this condition and make him as her puppet.
