Nikolai Avtotor is a supporting character in the anime Chaika - The Coffin Princess Avenging Battle. He serves as the second-in-command of the Gillette Corps, a field unit of the Postwar Reconstruction Implementation Agency, commonly known as the Kleeman Agency. A professional mercenary by trade, he is a capable and experienced fighter, wielding a large great sword comblade in combat. He is distinguishable by his short brown hair and mint green eyes. In terms of personality, Avtotor is portrayed as a loyal and dutiful subordinate, carrying out the orders of his superior, Alberic Gillette, without hesitation. His motivations stem from his role as a mercenary, following the directives of the agency to pursue and capture the Chaika clones and later to secure the remains of Emperor Arthur Gaz. Throughout the story, Avtotor remains a consistent presence within the Gillette Corps, participating in their missions alongside other members such as Vivi Holopainen and Zita Brusasco. As the narrative progresses and the greater threat of the Emperor's resurrection becomes apparent, the Gillette Corps shifts from antagonists to uneasy allies with the main protagonists, and Avtotor contributes to the final confrontation. He does not undergo significant personal development, remaining a steady, combat-focused secondary character whose primary function is to support his team in battle.
