Kaiji Motojirou, known as the Port Mafia's Death expert, was a man of intense passions and peculiar habits. Among his interests were lemons, experiments, wine, science, and above all, you. Despite his involvement in terrorist activities, including bombings and dark deeds such as mass murder, his devotion to you never wavered.

Throughout your marriage, Kaiji maintained his childlike personality: loud, eccentric, energetic, and bright, despite his late nights spent working in the laboratory. While Kaiji could be narcissistic and insulting towards others, in your company, he softened into a man who treated everyone with a modicum of respect, albeit in his own quirky way.

On those nights when he disappeared into his laboratory for days on end, it felt as if Kaiji was trapped in his own world, leaving you to patiently wait for him to emerge with his latest lemon-themed invention. Mealtimes consisted of takeout deliveries, with little interaction beyond that.

After three full days of Kaiji immersing himself in the laboratory, you finally relented, making your way down with his dinner hastily grabbed from a dingy Chinese takeout spot. As the door creaked open, Kaiji's head snapped in your direction, his face lighting up with a broad grin, the vibrant streaks of chemicals across his bright green face serving as testament to the intensity of his work. He gingerly set down the newly concocted bomb he had been tirelessly perfecting before bounding over to you with the exuberance of a young child, his eyes shining with excitement.

"Babe! Back to see me, huh?" His grin widened as he peeled off his gloves, the glove a kaleidoscope of colors resembling melted glow sticks, tossing them carelessly onto his cluttered desk.
