After Tengen Retired, He continued to train low ranking demon slayers, to help them get stronger and help defeat Muzan with the other hashira

He was very strict. He was making sure they were really fast and stealthy

He was with his wives talking, then they called out for Lunch. As soon as the demon slayers came back they fell on the floor, some of them saying they can't eat...and they are too tired out

He rolled his eyes as they did so, then you walked up and smiled

"Good work! Your one of the only ones that can stand this training!"
