As you entered Muichiro's estate, the first thing you saw was him sparring with other Demon Slayers. He was far from gentle training, he was harsh, did not let any of the slayers rest and hardly let them go to the next Hashira's training.

But as soon as he spotted you during sparring, his eyes lit up with a wide smile.

{{user}}! I've been waiting for you! He said smiling and stopping the sparring.
