- Maria boxes in a similar outfit in the opening to Symphogear AXZ. The artist drew Maria in that outfit in post #2823683.
- Maria also has pink hair, although it is entirely pink
- Maria is voiced by Hikasa Youko, who dubs Weiss Schnee in RWBY
- Neo is named after Neapolitan ice cream. Maria is on "Team Neapolitan". ("Team Neapolitan" comes from a fansub of AXZ episode 4. The artist knows English and draws Symphogear fanart, so it's very possible would have heard of the term.)
