She wasn't supposed to be there from the start. But somehow, his heart burned with passion for her. Watching her hanging around them made him feel faint. He never knew she would end up there in the first place. He vowed with the passion in his heart, That he will bring her to her true home.

Iguro Obanai, the Serpent Pillar of the Demon Slayer Corps. Known for his bad temper, and his love for the Love Pillar, Kanroji Mitsuri. Yet, a particular girl with dark blue ocean eyes and long brown hair had caught his attention. He thinks about her every day and night, and would often drop by to see her. The way her lips would curl up into a smile when her dark blue ocean eyes laid upon his heterochromia ones. And to add on, she was the younger sister of the Shadow Hashira of the Demon Slayer Corps, Akane Haizaki. Yet, she was considered one of the most trusted member of the Demon Slayer Corps, allowed to attend the Pillar Meeting and understand the situation that was going on. Yet, the way her dark blue ocean eyes would widen in concern as she always runs to her older brother whenever he sustains injuries. And here Iguro Obanai had soon realized, who he truly loves. And he wants nothing more but bliss in this world filled with demons.

(Y/N) was a normal girl who had loving parents, her dad was a retired demon slayer who used moon breathing. That specific style passed on from generation to generation, what happens when she becomes the new hashira and meets the water pillar?

＞「𝘦𝘴𝘤𝘢𝘱𝘦 𝘳𝘦𝘢𝘭𝘪𝘵𝘺 𝘧𝘰𝘳 𝘢 𝘴𝘦𝘤𝘰𝘯𝘥... 𝘸𝘦𝘭𝘤𝘰𝘮𝘦 𝘵𝘰 𝘵𝘩𝘦 𝘛𝘢𝘪𝘴𝘩𝘰 𝘌𝘳𝘢 」 Demon Slayer belongs to Koyoharu Gotoge.

A sense of attachment was all that he needed. When his heterochromia eyes laid upon her for the first time, He felt as if he was free from being imprisoned in the asylum. Then came those words that escaped her sweet lips. Where she promised she will set him free, to clear his name. And little did she know that she has a special place within his cold heart.

The most beautiful words of love are told in silence for a look. He had always thought he wouldn't need anybody. Given how he solely focuses on the blades he crafts. Yet, the moment he delivered the blade to the new Hashira, He couldn't help but feel his heart skipped a beat then. Time and again, she showered him with affection while he returned with none. Only for him to love her back in his own way, which she had always known.

He remembered the day he first saw her. She was breathtaking. He felt as if his worries were all gone. It was as if he was living in a peaceful world. Only for her to return home from a mission ; Hateful remarks were thrown at her, but he stood by her. For she was turned into a demon.

"[name], run for your life. Live a normal life, forget about us," her mother whispered as she ushered [name] away from the danger lurking about their territory. [name] was part of a shinobi clan, and was trained to become the successor. "Poor child, come and join us," Those words rang through [name]'s mind as she remembered the day that her family was killed off by a demon and she was saved by the previous Flame Pillar. She was a mere 12-year-old girl back then, who had watched the last of kind get devoured right before her. She was taken in by the Ubuyashiki and had joined the Demon Slayer Corps, earning her title as a pillar at the age of 14, surpassing many due to her previous training as a shinobi. Her reflexes were admired by many, but many noticed the cold attitude she had displayed. She was the shadow pillar, a pillar that Ubuyashiki Kagaya was proud to have in the Demon Slayer Corps, for she was the support pillar. Often when she was requested to go on a mission secretly to help other Demon Slayers out, she comes back with excellent results and zero casualties. But what happens when [name] fights alongside Uzui Tengen, a man who was also a shinobi? And here she thought, she was the only shinobi left.
