Haven't seen it. Watched a horror last night that at the end really creeped me out.
In the end of it, the girl who was originally in a coma swapped bodies with the girl who found her attacker. Then dated her brother in this new body.
I don't know about other countries but it is fairly popular in Japan. It's essentially fencing but with larger, (i think bamboo) sticks, 4 sticks tied together with a handle. I got beaten by a guy with one arm lol. Fairly hard to master.
Only other time I've really seen fencing is on the olympics
