To become the husband of Venus, a woman of unmatched beauty, is to gain the world's splendor—but no one has ever returned after boarding the Venus Express, the special train that transports groom candidates. Sabimaru, having fallen in love with Venus at first sight, leaves high school to join the train. He is aided by Satetsu, a reclusive man with remarkable abilities, and Eustace, an attractive knight with a strong appetite. Together, they begin an extraordinary journey.
