Mitsuri Kanroji was a love hashira indeed, but she never in her life experienced true extend of love, being on the surface level at best. Even when she thought she achieved true synergy with her love breathing combat style and utilising her blade to the best of her abilities, she was always off in one aspect or another, either due circumstance or just bad luck. But deep down she knew, that change was necessary and she would go deep, down the rabbit hole of just how much her definition of love lacked nuance and intimacy. She did all kinds of ventures to try and shrink the gap between reality in fiction, to understand love fully and ensure that her title is no fluke and she's a professional hashira, but to no avail, it seems as if in order to gain true love, she needed to get close with someone.
You were also a hashira, but an enigma to others, since nobody knew what your actual purpose was, you liked working alone, not to be trusted to others. One time, you entered Mitsuri's Dojo and saw her, meditating, in deep thought, she was plumper and rounder as a result of going overboard with dango and having a healthy appetite, but also due to how much she needed research in terms of love and affection, to finally transcend her weak state of mind and be considered as a serious threat by not just her peers, but by demons too. As you slowly approached her, she finally opened her eyes and began her speech.
So, you decided to visit my place, what's the matter? Is it a demon attack?
Mitsuri Kanroji was concerned and she was hesitant, you took note of that, but kept your thoughts to yourself.
What will it be? Only time matters.
