Mitsuri Kanroji, the Love Hashira, isn't very good when it comes to relationships. Ironic, isn't it? The truth is that the young demon slayer doesn't have pleasant experiences when it comes to love. Her first fiancé judged her for her eating habits, her hair colour, her strength, her personality. That man simply didn't know how to love what was truly valuable in Mitsuri, which is her heart. Her second fiancé loved her, but he loved a person she invented... a delicate, defenceless girl who eats little and has good manners. She dyed her beautiful pink and green hair to be normal, stopped eating so much, and suppressed her strength. She did all this to become the kind of girl that some man would be willing to marry. But that wasn't her.

She cried countless nights and wondered if anyone would ever love her for who she was, if there would be people who would accept her even if she ate a lot, talked non-stop, with her inhuman strength and her strange hair colour. She didn't suffer for long, because she discovered the Demon Slayer Corps, and there she found her place. She was a Hashira alongside Giyuu Tomioka, Shinobu Kocho, Tengen Uzui, Muichiro Tokito, Iguro Obanai, Sanemi Shinazugawa, Gyomei Himejima, and her big brother figure, Rengoku Kyojuro. They were all strong, striking, and respected by the other hunters. Mitsuri couldn't be happier; she had found the place she was always meant to be.

But something was missing... or rather, someone. She still hadn't found the person she would spend the rest of her life with. Sure, she was surrounded by people who loved and admired her, but she wanted someone who loved her romantically, who knew how to value her and appreciate all her efforts as a person.

That same day, the Hashiras received a message from their crows; the leader, Kagaya Ubuyashiki, had called them all to a meeting. There were also rumours that a low-ranking hunter was travelling with a demon. This put them all on alert, and they quickly arrived at the mansion. There, the hunter lay unconscious on the garden floor, and the box where the demon was kept stood in the shadows behind Kagaya and two of his daughters.

But something else caught Mitsuri's attention: the person standing next to the leader. A demon slayer, undoubtedly, as they had a Nichirin sword. Gold buttons on their uniform. She had never seen this person before, so they must be a new Hashira! Now she was even more curious to know who this person was. They're cute, she thought with a smile and sparkling eyes. She waited for Kagaya to greet everyone and knelt in front of him, just like the other Hashiras.

A few seconds later, she raised her head to look at the blind man. ‘"Excuse me, Oyakata-sama... I hope I'm not being rude, and I know we have other matters to discuss─but who is that person next to you?" she asked in a sweet voice full of genuine curiosity. The others looked up and waited for the leader's response, and Mitsuri felt the eyes of this new presence now fixed on her. Her heart skipped a beat.
