He didn't know how him and Nezuko got separated but still they had to do there best to not let anyone get eaten.
Zenitsu kept slashing as much flesh as he could there was a lot of it, he hopes Tanjiro and Inosuke are protecting the people up in the other carts or at least trying to behead the demon.
"Thunder breathing 1st form: Thunder clap and flash!"
Zenitsu had used the same move again and again, he couldn't give up what would Kaigaku or Gramps think of him if he did!?
Zenitsu dodged an attack from a piece of flesh and sliced it, he had to keep going even if his body is screaming at him he has too! Zenitsu then noticed another piece of flesh aiming at a passenger and he quickly went to slice it, but it was a trick.
"What the!" Zenitsu said as the piece of flesh grabbed his wrist he tried to use his other arm to get free but another piece of flesh had grabbed his arm.
"No no no no!" Zenitsu panicked as the flesh had grabbed ahold of all of his limbs and started to crush them while other pieces of flesh were aiming for the passengers.
"NO!"
Flashback
Zenitsu was at the butterfly mansion it was currently nighttime.
Zenitsu was walking back to his room so he could go to his sleep but something caught his eye. It was Kaigaku he was awake using his sword for something was he training?
Zenitsu decided to go check up on him, he quickly made his way over and was about to call out his name before Kaigaku had cut the dummy with his sword several moons coming out of the blade.
Zenitsu stood there breathless, what kind of breathing technique was that?
Zenitsu didn't know how long he stood out there for until Kaigaku noticed him. Kaigaku dropped his sword before running up to hug him.
Zenitsu hugged back as he kept looking at the training dummies, all there heads were cut off along with there arms and legs, he needed to find more about this breathing technique.
And that's where Zenitsu found himself watching Kaigaku practice the breathing every night until he had to go back into one of his deep sleeps, but Zenitsu had been analyzing his every move the way he steps and slashes.
Flashback ends
Zenitsu breathes in.
"Moon breathing 1st form: Dark
Moon Evening Palace"Zenitsu cut up all the flesh that was holding him in place.
He then got in another stance and breathed in using total concentration breathing.
"Thunder breathing 1st form: Thunder clap and flash sixfold"
He dashed all over and cutting up all the flesh that was attacking the passengers, "don't you dare hurt these passengers!" Zenitsu yelled vein popping out of his head as he kept slashing up.
"Mhm!"
He heard a noise of pain, Nezuko she is hurt.
He was about to go the other cart Nezuko was in but flesh blocked his way.
"I can't get to her in time!" Zenitsu thought as he saw all the flesh in his way, but if he was able to use the speed in Thunder breathing then.
Zenitsu felt electricity through his legs he jumped out of the flesh before dashing forward into the other cart destroying everything in his way.
He cut Nezuko out of the flesh trap and got into his stance.
"Thunder breathing 1st form: Thunder flash and clap sixfold!"
