The Tenth Pillar. (Kimetsu No Yaiba X OC)

Hiiro vs Douma

Their eager weapons whip and trash, the steel against steel sings a macabre song. Douma and Hiiro clashed again, sparks flying and deadly glares were exchanged.

The Upper Moon was able to escape from the black blade, but he was not unscathed at all. His regeneration wasn't working as he expected to, it was slower and if he was using his blood demon art, he couldn't generate at all.

"You're having trouble?" The night pillar mocked his foe as they broke the strength duel, taking distance between them.

"And you're underestimating me." Douma was grinning behind his fans, he could waste battle time and heal himself. "You're not attacking me with your Breathing techniques."

Hiiro Kojima couldn't contain his laughter, even when he was mocking the demon, his sharp eyes never lost their target.

"I know that you can't regenerate, are you an idiot? Why do you think that is for?" He pointed his sword at the demon, the black blade had some of the Upper Moon two blood, still crimson and fresh. "Take your time to power up. It doesn't matter if you are at your peak or at your worst. I'll bring you down, you'll see.

A smile drew itself on the demon's face, he won't tolerate such disrespect, he was being looked down.

"Blood demon art: Barren hanging garden!" A series of ten successive attacks were generated by the blonde man as he danced around with his fans creating razor-sharp gusts.

The man in black made some acrobatics to evade the attack, he landed safely, ready to strike again.

He smiled as he lifted Zangetsu into the air and with a extreme speed, he closed the distance between him and his foe.

"Breath of the night, second style. Dusk impact!" The swing of the blade had such force on it that even when Douma evaded a certain death, the ground was shattered by the sword strength. Hiiro eyed his enemy. "Didn't I told you? Take your time to power up. I'll take you down."

Shinobu Kocho liked to tend the wounds of the demon slayers, but when it comes to her own injuries she's hard to handle. Her ribs were plummeted and she could barely stand, even with the medicines and the muscle relaxants.

"That would do it, Onne-chan." Kanao cheered as she cut the bandages. The young girl was the most concerned about Shinobu's health status. She was unable to fight anymore.

"Let's go, Kanao. I can't fight anymore, but we can treat the wounds of the demon slayers." The Butterfly girl stood up, gracefully and prideful.

Even though she won't help at the battles, she could still be useful in the battlefield. Her sister smiled at the determination of her sister.

The pair of female swordsmen ran through the maze, every turn they took was similar to the other, they felt like there was no way out. Fortunately, a yellow with white triangles pattern haori boy found them.

Zenitsu was resting against a wall, covered in bruises and blood, yet he was victorious, he defeated Kaigaku and got revenge for his grandfather.

"Hello~" Shinobu Kocho had a flashback, it felt like when she found him injured, back in the mountains of the spiders. "Are you okay, Zenitsu-kun?"

The Butterfly sister were surprised when the boy lifted his hand, giving then thumbs-up and a wide smile plastered on his face.

"I did it." He mumbled weakly.
The insect pillar blinked twice and giggled as she patted his head, she felt like a mother, proud of her little boy.

This caused her to be flustered by the thought of the night pillar being the father, since he's the boy's sensei.

"Hiiro-kun will surely praise you." The amethyst eyed girl began to treat the blonde's wounds.
