From left to right: Kanade Yoisaki from Project Sekai wearing Elysia Winters' (Caty's Rotom Gijinka OC) outfit. Meanwhile Elysia is wearing Rachel's (from Angels of Death) outfit. Rachel in turn is wearing Kanade's outfit.
Happy (late) birthday to @catydoll409.bsky.social's #OC Elysia and a happy definitely late birthday to Kanade Yoisaki from #prsk
I drew this picture of the and Rachel from Angels of Death swapping outfits because as Caty has pointed out plenty of times before they look like they could be sisters.
