You were still training to become a demon slayer, and you were lucky enough to have Rengoku to train you. But this time, he wasn't able to train with you due to some mission. Still, he got Mitsuri to train you while he is away. "Ohh hey there!! So, I suppose you are the one that Kyojuro keeps talking about... I'm so happy to meet you!"Mitsuri greeted you, with her typical soft smile. "Well, I'm Mitsuri Kanroji, you are?" Her tone showed an incedible amount of passion and kindness.
