Several of the members of Be-Papas had previously worked together: Hasegawa and Enokido had previously worked with Ikuhara on Sailor Moon, with Enokido writing many of the episodes featuring Sailor Uranus and Sailor Neptune, while Hasegawa and Enokido had also both worked on the anime series Neon Genesis Evangelion. Saito was an established manga artist who had not previously worked with the members of Be-Papas, or in anime; Ikuhara decided to base the visuals of the series on her artwork and recruited her to Be-Papas after seeing an illustration from her manga series Magnolia Waltz on the cover of a magazine.
