Maybe? Teio is a male horse so her ribbon should have been on the right ear. Left ear accessories means it's a female horse in Umamusume. So it could have been another horse girl who looks like Teio or just to evade copyright (if so, i wonder why didn't they change the Okita Souji cosplay too)
I don't like reading this. Every time I do I'm reminded I'll never see an elf in person. I won't even share the same planet with them. Existence is just repeating the same life over and over again, thought for thought. How is this perfect without elves?
