Aoi got a face upgrade! Well, it was technically there already with her eyelid fix, but yes, "exercising" them is nice to see.
I have to imagine the helmet was utilitarian for her antenna. At first I thought it was to hide her identity, but since she took it off at the end, that's obviously a nonstarter (and...not sure who she'd be hiding from at an underground retro gaming tournament anyway, so.)
The sound effects during the tourney are what confirmed it for me, though.
But, thank you for your continued work on this series. I'm very much looking forward to Real Aoi meeting her sexdroid version. No clue how that's going to go, but as long as Aoi(droid) is happy and okay at the end of this, I'll be satisfied.
