𝐋𝐞𝐯𝐢𝐚𝐭𝐡𝐚𝐧 𝐱 𝐎𝐭𝐚𝐤𝐮! 𝐑𝐞𝐚𝐝𝐞𝐫(𝐅𝐞𝐦𝐚𝐥𝐞) He saw her once in the human world, only to feel attracted then. Yet, ever since he returned to the Devildom, did he continue to think of her. The way she smiled after she apologised for bumping into him. Only for her to appear in the House of Lamentation as an exchange student. Where Leviathan started to keep his distance, for he never believed his worth. But little did he know, that she and him had something in common. And thus, Leviathan found his home in her arms.

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.

"Trust is important because it is the basis around which all human relationships revolve. Without trust, there can be no relationship. Trust can come naturally or it can be manifested. But then again, it will be my decision to trust you," Those words lingered through his mind as Kamado Tanjiro, the hidden Upper Moon that was tasked by his supposedly only master, Kibutsuji Muzan, to assassinate the ever so calm Ubushiyaki Kagaya. Yet, nobody knew he was a demon. Until she found out.

He was known to be a hot-blooded individual. Showing little to no concern about anything or anybody. Except towards the swords he creates with his burning passion. Many disliked him, finding him to be very difficult to approach. Given how hot-headed he was, yet the passion he had for swords made him stand out from most of the swordsmiths who made swords for the sake of it. He didn't need anything else. Nor did he need love. He just wanted to create swords after swords. Only to realize he had other feelings, for a particular Hashira. Then many started to question then, why would someone like her fall in love with someone as hot-tempered as him? And how?

"[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.

He was known to be reserved. And she was known to be the newest Upper Moon to ever exist in the era. Yet, she was so similar to him. He watched her often getting called upon by their Master. He watched her smile at something that he couldn't understand. That's when he realized, she had retained her human emotions. Unlike him, driven by a certain hatred within his demon soul. Yet, on the night he went out hunting together with her, watching the way she glowed beneath the moonlight. He felt a burning sensation within his cold heart, a feeling he found familiar but was long forgotten once. Was it love? He thought. Soon it turned into a competition, a constant need to see her every day. Getting irritated whenever the other Upper Moons were near her. He was known to be reserved, but oh well, he was known to be hot-headed when it comes to her.

She was born special despite being blind. She is persistent and enduring. She is none other than the younger sister, Let alone the tsuguko of Himejima Gyomei. The only thing worst than being blind, is having sight but no vision. But all she ever wanted, was to see the colors of the world.

There was something awfully great about her. That made them want to protect her at all costs. There was something awfully pleasant about her, That they feel at ease when she was around them. There was something about her. That made them decide that she was their favorite.

"I promise to come back to you," - Tokito Muichiro. They were so innocent. Just playing in the courtyard. The adults called it puppy love But little did the adults know, It meant a whole lot to them.

Opening up to him was another milestone but he was happy with it. Little by little did her heart heal and she started to fall. To fall for the ever so reliable Master of hers.
