I was expecting a lot from Cait's debut on LoR... but then nothing happened.
I don't know if Rito is against it or just loves to tease us with these two.
Someone on another thread asked about the origins of Neko / Tachi. It's quite simple. People wanted to use words that sounded like Nico/Maki. Nico became a neko and Maki was a tachi. Everyone else in Tokyo went, "oh, that makes sense!"
