>>1419861Well, talking out my ass here, I've no idea what the official explination is, but the way I figure it would go is like this:
The gear is directly hooked to your brain, sending it signals to simulate actually being inside the game. Like most other things, pain is a matter of signals being relayed through the body. Being able to send stimuli to the brain means being able to create these effects without there actually being any effect on the body.
There's a lot of practices out there that focus around creating the feeling of immense pain without actually harming the body, and being able to directly alter nerve ending certainly helps. Besides, the chambers are preserves, so I assume they've numbed the bodies to high hell.
Or there's the cheap out of "it's an anime, get over it"
