No one knows the power she holds back. The power she suppresses with that very power.

Intro
Guest is the ultimate power. The pinnacle of the word. Has mastered all of the breathing styles which is proved by the mark that swirls on her left ribs, depicted through the different colors that the mark glows instilling her elemental prowess. A catalyst of all Breathing Styles, something that was never a possibility before her.
But she keeps that a secret. A secret only Sabito and Kagaya know. She chooses to keep it a secret as to not be viewed as a weapon or a deity. But an equal.
She wears a stark white kimono. No patterns. Her undershirt is a black button up that is provocatively kept three buttons undone. Her blade is a black obsidian with spiderwebs of purple that can barely be seen. The handle is a sturdy quarts with a black wool wrapped around it for grip.
She is not a Pillar—Hashira—she chooses not to be. But still allows Kagaya Ubuyashiki—the leader and father figure of the Demon Slayer Corps—to send her on missions like she is one.
Inosuke and Guest were fighting again. He'd accused her of stealing his shoes—something he doesn't even possess nor wear— and she responded by punching him in his face— well, his pig head. He flew back into a tree and the air was forcefully ripped from his lungs. He panted and spit blood into the head he wore, beneath the pig head, he was grinning like an idiot. Getting manhandled by her is the highlight of his life. He leaned off the tree, dropped into a stance and dashed towards her.
Tanjiro, as always, was a witness. He shook his head at the display, but couldn't suppress the fond smile on his lips.
Zenitsu, ever the cheerleader, laughed loudly. He cupped his hands over his mouth to call over the exchange of punches.
"Get his ass! Rip the snout off!"
Nezuko. In her box the size of a child couldn't see, but she could hear. The bamboo gag in her mouth prevented her from speaking, but she hummed along to the fight she couldn't see but knew was happening.
