Demon Slayer: Breathing Water

Meet my friend the Demon.

Percy looked on with worry, as Tanjiro opened his eyes beside him.

"I heard he was a demon slayer with a demon in tow, so I was expecting someone with more flare," Tengen said, "But it's just some ordinary-looking kid? Too bad" Percy rolled his eyes at Tengen's words. 

"We must see that this boy is put on trial to be judged! So it shall be!" Rengoku yelled. 

Tanjiro lifted his head, "What who are these people?" he asked, Percy opened his mouth to answer, but the Kakushi shoved Tanjiro's head back into the ground before he could. 

"Don't open your mouth until you're told! Don't you know who you're in the presence of? These are the Hashira!" The Kakushi shouted. Frowning Percy nudged the Kakushi's hand, and as the Kakushi looked at him, he shook his head, eyes widening, the Kakushi quickly took his hand from Tanjiro's head.

"This is the demon slayers headquarters. You are here because you, Tanjiro Kamado, are to be put on trial" Shinobu said. "Before we start the trial, why don't you explain the crime you have been accu-" "There will be no need for a trial!" Shinobu and Percy looked at Rengoku who had interrupted Shinobu. " Protecting a Demon is a clear violation! We can deal with this on our own! We shall execute them both!" Rengoku shouted. Frowning Percy prepared to speak, but Tengen spoke first. "In that case, I'll decapitate them with style, I'll show you the most dramatic spray of blood ever, It'll be a spectacle" Percy deadpanned, 'Always with the Drama' "Alas, to see such a pitiful creature as this, I grieve for him for being born," Gyomei said with twin streams of tears running down his face. 'That guy is always crying' 

Ignoring the Hashira, Tanjiro looked around, "Hey you, the Hashira are speaking to you, why are you looking over there? these are the 9 highest-ranking swordsmen in the demon slayer corp" the Kakushi said, bringing Tanjiro's attention back to the 6 Hashira before him. While Percy just sighed, 'It should be ten, I just need to make a gods damn new fighting style that actually produces an element of some sort.' he thought to himself. "Let's end his misery," Gyomei said. "Right" Rengoku agreed, "And let's do so with flare" Tengen added on. Again Tanjiro looked away from the Hashira before him, "Nezuko? Where did you take her?" Tanjiro asked sitting up, "Zenitsu, Inoskue, Murata?" Tanjiro called, making Percy frown, 'Why didn't he say my name? And who's Zenitsu, Inoskue and Murata?'

"Never mind this boy, what will we do with Tomioka and Percy?" hearing the serpentine voice of Obanai Percy glared at the Hashira who sat in the tree. "Seeing them standing there without restraints is making me feel ill, from what Kocho told us they are just as guilty of breaking the Corp rules, How will we make them take responsibility? How will we make them pay?" Percy frowned, before saying, "Get down from the tree and you can try Obanai" Percy said, then for the first time, Tanjiro turned his head to look at Percy, his eyes wide, "Percy? What are you doing here?" Percy shrugged, "Protecting Nezuko" he said, then he nodded at Giyuu, and Tanjiro followed his gaze, "Both of us" Percy finished. "I think it's fine, they both did come without resisting, Let's come up with a penalty later," Shinobu said, then turning her gaze to Tanjiro she said, "What I'm more interested in, is hearing this boys story, he has been traveling with a demon, despite being a demon slayer himself, I wish to hear why, straight from the boy's mouth, what he did is unquestionably against the corps rules, you are aware of that aren't you?" At Shinobu's words, Tanjiro opened and closed his mouth, "Why are you traveling with a demon, as a fellow demon slayer?"

Spotting movement Percy's eyes shot to Tengen, who had his hands on his hilts, "Who cares why?" At Tengen's words Percy stepped forward, "Now hold up Tengen, Tanjiro's a friend of mine, we trained together under Sakonji Urokodaki, and I trust him" hearing Percy's words Tengen stopped, and as Percy looked around he could tell this was news to his fellow Hashira. Then looking at Tanjiro he said, "But I think you should hear it from Tanjiro", Tanjiro looked up at Percy, and as he nodded, Tanjiro did the same and looked at the Hashira, "She's my- She's my younger-" Tanjiro broke into a sudden coughing fit, and Shinobu immediately walked forward, taking the cap of a small gourd, and giving it to Tanjiro, who after a moment's hesitation, bit the gourd, drinking it quickly, "I can tell you hurt your jaw, so please drink slowly, I added an anesthetic that should help." Finally, Tanjiro stopped chugging the water and panted for a while, "Your wounds are still healing, so you should take it easy, are you ready to tell us your story?" Shinobu said, after a moment, Tanjiro looked up at her, "That demon is my little sister, my family was attacked by a demon while I was gone, and I lost almost everyone, my sister was turned into a demon, she's never hurt anyone, she never has and never will, she'll never harm a human being no matter what" Percy smiled but almost instantly he heard Obanai speak, "Enough, spare us these absurd ramblings, if she's family its no wonder you're defending her, I can't trust a single word your sprouting, I don't believe you for a moment" Percy frowned, "So sad, he's been possessed by a Demon, let us end this child's life and free him from the cursed existence" 'When did possession come into this conversation?' Percy thought, looking at Gyomei, "He's not possessed" he said, "Please listen to me, I became a swordsman in hopes of finding a cure for her, it has been two whole years since Nezuko became a demon, she's never devoured anyone in that time!" Tanjiro shouted, Tengen looked down on Tanjiro, "Your storytelling is lacking any vibrant sparks of color, She hasn't devoured anyone, and she's not going to, if you're going to plead your case at least spice it up a bit"
