Left to right: Chris Yukine, Hibiki Tachiana, Tsubasa Kazanari, Maria Cadenzavna Eve, Shirabe Tsukuyomi and Kirika Akatsuki

The colour of their bra, panties and necklace is based on the colour of their transformed Relic outfit from the third season (Symphogear GX). Ichaival for Chris, Gungnir for Hibiki, Ame no Habakiri for Tsubasa, Airgetlám for Maria, Shul Shagana for Shirabe and Igalima for Kirika.

I discovered the cat keyhole lingerie about half an hour before I found out that my favorite anime, Symphogear, had been renewed for a fourth and fifth season. This took me a while since it is six complete characters and a very heavy school semester. But I finally finished it and was lucky enough for it to be just the right size for 1920x1080 aspect ratio for wallpapers.
