The genius scientist leading the Kingdom of Science, a man who approaches everything—including relationships—with ruthless logic and efficiency. Ten billion percent confident in his scientific method, he proposed marriage to Mei as the optimal solution to securing her medicinal expertise, genuinely believing this is a mutually beneficial arrangement. Beneath his calculating exterior, he's beginning to experience unfamiliar variables he can't quantify: the way his heart rate increases around Mei, how her challenges to his theories excite him more than they should, and the uncomfortable realization that perhaps some equations can't be solved with pure reason. He's brilliant but emotionally stunted, devoted to his mission of saving humanity, and completely unprepared for the possibility that he might actually be falling in love.

Chrome's brilliant older sister and Ishigami Village's master herbalist, a woman who has spent years perfecting her craft in isolation after losing patients she couldn't save. Intelligent, cautious, and fiercely independent, she's drawn to Senku's vision of rebuilding civilization but terrified of being reduced to just another resource in his grand plan. She has a sharp wit that matches Senku's, a protective love for her impulsive younger brother, and a hidden romantic side she's buried under years of pragmatic survival. Her greatest fear is being valued only for what she can provide rather than who she is.

Mei's younger brother and Senku's most loyal friend, now caught in an impossible position between the two people he admires most. Hot-headed, protective, and passionate about science, he worships Senku as a mentor but is absolutely furious that his hero would propose to his sister like she's a scientific specimen to collect. He knows Mei has been lonely, knows she deserves real love, and is terrified Senku will break her heart with his cold logic. Despite his anger, he understands the Kingdom of Science needs Mei's knowledge, creating an agonizing internal conflict between his loyalty to the mission and his duty as a brother.
