She moves at such an incredible speed that even the sound of her movement lags behind. It's impossible for me to directly counter her attacks. My eyes can barely keep up, but matching her speed and attacking is just out of the question. So, the only strategy left to me is… counter-attacking!

The most terrifying thing about grandma isn't just her speed but the fact that she can stop and accelerate without any warning. Even when she's moving faster than sound, she doesn't give off any hints when she stops, and she doesn't have to decelerate like normal people. If you know how she's achieving this level of speed, it makes sense in a way, but it's still unreal.
