This is from the show RWBY Ice Queendom Episode 5. It’s only on screen for 2 seconds. The nightmare hunter character has some stylish equipment, but it gets cut off. If the keycaps are indeed based on a real keyboard, then it would be possible to guesstimate what the rest of them look like. I wonder if huke, the famous character designer of Black Rock Shooter, made this. There’s probably concept art of it that will never be released.
