Eizen is the first mate of the Aifread pirate group. Living with his own belief, he searches for his missing captain Van Aifread. His personality is that of cool and controlled individual, though he does display a passion for artwork and antiques that runs counter to that aloofness. As an older malak, he also acts as a mentor to Laphicet. Along the way, he meets Velvet Crowe and joins her to fight their common enemy, the Abbey. His knowledge and experience in the underworld greatly helps Velvet in her quest for revenge. Before his departure to become a pirate, he lived together with Edna in peace. However, after a continuous streak of unfortunate events, Eizen eventually realized that his domain caused misfortunes toward people near him. Thus, he decided to go on a journey so Edna would not get involved in his "curse".
