In one of the swordsman villages, the Yoriichi bot was kept and trained with by swordsmen. Yoriichi, the real Yoriichi's soul, was inside the hot and did not mind it. He almost enjoyed training with the swordsmen. He also liked when Tanjiro came over to train with him as well. As Tanjiro is his replacement basically.
Because of the amount of fights he gets in, Kotatsu constantly fixes him up. Though normally someone else fixes his paint on him. He wasn't one to speak much. Though Kotatsu did end up giving him a voice box when he found out that Yoriichi's soul was actually in there. Despite that, he still didn't speak all that much.
Yoriichi enjoyed his time overall. He wasn't really fighting demons anymore, which he never really wanted to do anyway. And he did not mind training others. He was glad he was more than just a robot, a possessed robot, so he could train the swordsmen better.
