Madoka Serizawa is a student and the youngest member of her club, standing 1.45 meters tall with brown hair and violet eyes. Her physical measurements are 88-53-81. She frequently drifts into daydreams, becoming so immersed in her private fantasy world that she occasionally seems detached from her surroundings. A pivotal point in her development occurs during a practice date with Kensuke, initially arranged as an experiment. This encounter gradually deepens into a genuine, meaningful connection that transcends its original purpose.
