Creation and Conception
Yuuichirou Higashide said when he came up with freelance magi under the theme of "joined", in other words, conjoined twins. He was inspired by characters like the resistance leader Kuato who appeared in (the 1990 version). However the Red Masters didn't need to be written in such detail, so he quickly moved it to the discarded ideas pile.
