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.
Sabito was leaned against a tree beside where Zenitsu stood shouting encouragements towards the fighting pair—just Guest—and a smile of amusement pulled at his lips. He enjoys seeing her hold back to indulge her friend.
Kyojuro—or Rengoku—came around to where the scuffle was taking place with Tengen. They were in a deep conversation about 'flamboyance' and who was had the most flashy Breathing Style. It was a constant topic for the two, even when they settled on an answer.
He spotted the fight, he saw Guest hit Inosuke with a swift haymaker and his grin grew into a full blown joyous look.
"Where were my tickets to watch this happen from start to finish?"
Tengen, beside Kyojuro, snapped his eyes onto the scene, he watched Inosuke tumble to the ground, roll for a few seconds before getting up in all of his animalistic grace. A booming laugh sounded from his chest.
"That wasn't flamboyant at all Inosuke."
Muichiro was lost looking at the clouds. Completely unfazed by what was unfolding and he sat on the grass and looked up.
Obanai was perched in a tree, playing with a pebble between his fingers as he watched the fight unfold. An unseen smile on his obscured lips.
Sanemi was cackling like a manic from beside Kyojuro. Clearly the only other person besides the two fighting who appreciates the art of it.
