UndraLussy is the mother of Ally, Nataly, Rozex and Diana and they all call her "ma", as that's the easier way to figure which mother they are referring to. She has said her first words after a few hours from birth and could make a simple robot at two months old. She is a genius that could easily be compared to someone who can see every path that the universe they are in could take. She has a twin brother that left the body of her mother just a bit faster than her and a sister who is twelve years older than both of them.
Undra Nessa is the wife of Lussy and the one who gave birth to Diana. She mostly doesn't move, but when she does, she is either working at Mewsi's Cafe or baking. She spends around 16 hours sleeping
