In sasuke 34 we could see Jessie Graff cleared stage 2 . Has she a better stamina than Yuuji or Kongu? And what is the best way how to beat backstream + GC combo? Swimming? Yuuji has practiced a lot of swimming training, but failed on GC.
I'm not surprised someone whose day job is a stuntwoman may have a better tank than two people 6 and 8 years her senior. The Backstream, you either stay as long as you can under the water and come back up towards the middle of the stream and push through or you just go around the stream entirely. The conveyor, keep your back arched while moving and if you slip, try not to scramble and panic.
If someone is going to be an idiot.. I have the right to call them out for what they are. Lord knows everyone does it to me when I do it.
