The Next Morning

Everyone awoke at the same exact time, although Hayami still took some time. When Tanjiro and Zenitsu woke up, they looked at each other in gay panics.

"I-I'm in your bed! I-I slept with you! I-I spent the night in your…!" they cried in unison. "Fuck, fuck, fuck, fuck! Did we just…? Did we just fuck? Oh shit, shit, shit, shit, shit! Why'd I do that? Why the hell did I do that? That was stupid! I shouldn't have been so fucking stupid! Dammit, I'm such a fucking idiot for stripping down into my underwear? What the hell was I… what the hell was I even thinking?"

Tanjiro and Zenitsu banged their heads against the headboard of Tanjiro's bed.

Inosuke smiled. "Morning, loverboys."

Tanjiro and Zenitsu frantically put their clothes back on.

"I-Inosuke! Y-you woke up early!" Tanjiro said with a nervous laugh and a blushing face. "I-I'm so sorry you had to see that! I didn't know what I was doing!"

"Oh, uh… good morning, Inosuke," said Zenitsu casually. Then fear struck him. "I-INOSUKE!? Wh-wh-what are you doing here? I'm so sorry, I'm so sorry! Tanjiro and I didn't intend for you to see…"

"It's no big deal," Inosuke said. "Anyway, I think your daughter's waking up."

Hayami opened her eyes. "How long was I out?"

"A day," Inosuke replied. "I tried kicking you, but you didn't budge."

"Why the hell would you do that, Inosuke!?" Hayami cried. "What the hell is wrong with you, dammit!?"

"He's Inosuke," Tanjiro said. He sighed. "Let's forget last night ever happened."

"Aww! But I thoroughly enjoyed everything about last night!" Zenitsu cried.

"It was embarrassing!" Tanjiro cried.

"OK, OK. Wiped out of my brain," Zenitsu said.

"You promise?" Tanjiro asked.

"Pinky promise," Zenitsu said, interlocking pinkies with Tanjiro, which triggered a blushing response.

Hayami looked at them in disgust. "You two are disgusting. End of story," she said. "Well, now that I practiced my forms, I think it's time for a real battle. But only when a real battle presents itself, of course."

Tanjiro, Nezuko, Inosuke, and Zenitsu stood beside her. "We'll be ready when it does."

"As long as you don't engage in a threesome," Hayami said, eyeing Zenitsu especially.

"Wh-what makes you think I'd do something like that?" Zenitsu panicked.

"Because that's just the way you are," said the twelve-year-old girl.

Hayami tugged at her white belt and smiled. "If I'm gonna be a Hashira someday, it's time I begin my training."

"Big dreams for such a young girl," said Tanjiro. "But I have faith in you that you can do it. Since you're now an official Demon Slayer according to the Demon Slayer Corps records, you'll be due pretty soon for your first mission."

"Alright!" Hayami exclaimed. "A real battle is what I need right now!"

"But they are worried since you're the youngest Demon Slayer in existence at just twelve years old. They're saying you can't start your first mission until you're thirteen."

"Bullshit!" Hayami said. "I'm ready! You know I'm ready, dammit!"

Inosuke smiled. "I like her spirit."

"Don't encourage her," Tanjiro said.

"What!? You got a problem, you fricking Demon Corps? Huh!? If you have a problem with me, let's just sort it out right here and right damn now!" Hayami roared. "Come here and I'll show you that I'm worthy of slaying demons at twelve years old! My training starts now, dammit! Now, I say!"

"She could be my child, yet I am not married," Inosuke remarked. "I still am surprised how she came out of Nezuko and Zenitsu with this attitude and smarts."

"Yeah. It's uncanny how well she resembles you," said Tanjiro.

"Hey! Don't compare me to Inosuke! I'm my own fricking person, dammit! And I can prove it! I mastered all those forms in a day! A day! And I trained my ass off until my twelfth birthday to prove it! Tell me why I'm not qualified to be a Hashira! Tell me why I'm not ready for my first mission!" Hayami roared. "Come here right now and tell me, you fricking cowards!"

"I-I don't think that's such a good idea to irritate them like that," Tanjiro warned.

"What do you know?" Hayama said, crossing her arms. "I'm marching my ass right up to the Demon Slayer Corps and giving them a piece of my mind!"

"Th-that's not necessary!" Tanjiro said.

"I don't care. We're leaving," Hayami said. "Let's go."

Tanjiro, Inosuke, Zenitsu, and Nezuko all looked at each other. They were not about to take orders from a twelve-year-old girl. That just was not gonna happen.

"Ahem. I wanna kill those Hashira!" Hayami said impatiently, which got Inosuke going.

As soon as Inosuke got going, Tanjiro and his sister plus Zenitsu followed.
