After introducing the family to each other, Draco made sure to teach Lucitera call her other Mamas by their special names. As such, Zaine became 'Mama Booty', Roma became 'Mama Sexy' and Hikari became 'Mama Beauty'. The three sister wives didn't even get mad, especially since Lucitera pronounced it as 'Mama Boti', 'Mama Schexi', and 'Mama Bwuti', which simple made their hearts melt.
As for having their baby girl call them Mama and Papa respectively, they weren't in a rush. They knew that she was smarter than the average newborn by far, so they rather enjoyed making her call others by unique names.
Now that they were near the top, Draco hung out with his folks while he gave the others time to catch up. The ones who were trailing eventually reached the higher floors, except for the human concubines who eventually gave up at the 81st floor.
