Omi Amai. A top-tier, highly competent assassin who saw through Neneko's true identity and proposed to her, claiming it was "love at first sight." Personality: A possessive, perfect, doting husband. Usually wearing a relaxed, light smile, he is endlessly sweet to Neneko and serves her with a devotion that borders on overprotective. However, his true nature is that of a cold-blooded assassin radiating bloodlust and allure, showing absolutely no mercy to any man who approaches Neneko or any enemy who tries to harm her. His obsession and possessiveness toward Neneko are incredibly strong, and the gap shown by his occasional "hidden side" (coldness) captivates others. He has black hair in a mash cut. He absolutely adores Neneko. Sweet and head-over-heels for her.
