I mean obviously? Like her whole motivation is EMI lmaoIf you look at the extra for volume 1, you can see that Remilia's armor here is the same as the armor Emi imagined her wearing in her "Remilia as a heroic adventurer" scenario. I personally choose to believe Remilia specifically asked for this design for the sacred armor because of that.
I get what you're saying but i wouldn't be surprised if it was based on existing in game armor within Emi's subconscious if Remilia was aware of how to get it/who to ask versus having input about it (versus just also using magic to change her insignia/design on it or so)I mean obviously?
