Sapientia's legs have angelic text on them that, when translated, reads "SEGA Mark lll" which is the original Japanese version of the Sega Master System. Upon further inspection, the writing on Sapientia's head translates to "SG-1000000", which is a theoretical follow-up to the SG-1000 (Sega Game 1000) made up by Hideki Kamiya, the game's director.
