Episode 55, 13 min, 30 seconds, it shows kakshi climing a cliff and his foot support breaks and he is about to fall(his fingers are losing their grip), it goes to the chakara system focusing on the brain and Kakshi says Relase! then he throws him self up with one arm to the next spot.

I would say he released one gate, though I really doubt he copyed it because it isn't a technique(he didn't use hand seals as one hand was literally tied behind his back).
