Yae Sakura is a rabbit?

Just started the new Star Rail Patch story (4.0) in order to prepare for the article I'll write later today in the main blog and it's pretty hype to be honest, we're going to Planarcadia which is the home planet of of Himeko that has really strong ties with the Aeon Aha and is the place where the Astral Express fell in the past. The first thing we see before even reaching is a small scene with Yae Sakura, one of the ever recurring expy of this franchise. She looks stunning and she even has the same way of talking of Yae Miko from Genshin Impact. She even has a manga/light novel on her face (seems like related to the Astral Express)!

I'm curious about the ears though, as I mentioned in the title those are clearly rabbit ears, but I don't remember seeing any other unit in the game so far with anything resembling those. Is it a special race or just an accessory?

Seems like IPC is still meddling in order to try and create an anti-destruction alliance and they basically made sure we reached this place. The representative this time is Pearl who looks to be a beautiful lady. Himeko says that she has different appraoch compared to Aventurine, but she's still "cut of the same cloth". Black Swan also left us apparently so we technically have a free slot for someone else joining us in this journey? Hope it's someone that will change the dynamics within the team a bit...

Seems like the planet is currently in a ceremony period called "Phantasmoon Games" in which the winner "becomes an Aeon". It's clearly some sort of joke by Aha isn't it? There has to be a big catch to it...
