"Now for the twelfth form!" Hayami said, grasping her sword tightly as she got her footing and stance intact. "Also called the final form if you must know."

Hayami closed her eyes and focused on breathing. "This is called the final form for a reason. Despite how much training I do, this form is damaging so it must never be used at the beginning of a battle, but as a final blow!"

"Does that mean that no amount of Ice Healing can fix the hell it has caused to your body?" Tanjiro said.

When Tanjiro said that, Zenitsu panicked. "A-are you saying that it depletes your strength so you fall to the ground unconscious!?"

"Yes and yes. Whenever I use this form, it depletes my strength quickly and no amount of Ice Healing can help me regain my strength," Hayami replied. "So that means if I ever find myself in a situation using this form against a demon in battle, I will need days of rest after."

Tanjiro wore a concerned expression on his handsome face. "Are you sure there's no other way? What if we need you? What'll happen then?" Tears began to stream down his face as he descended to kneel on the ground. There, tears plopped down onto the ground.

Zenitsu followed suit and began crying uncontrollably. "If that happens, what will that mean? What if you die, Hayami? I can't cope with my own daughter dying, you know!"

"I won't die," Hayami said, kneeling down beside her fathers. "And even if I do, don't forget me."

"Don't talk like that!" Tanjiro said through tears. "If you die, I'll fucking die with you!"

"I'm too young and scared to die!" Zenitsu sobbed. "But if I had to die for a girl, then I would gladly do it. If Tanjiro was dying, then I wouldn't have anyone to protect me, so I'd have no choice but to end myself right damn here and right damn now!"

"If you die, I won't have any family left!" Nezuko cried.

Hayami put down her katana, her confidence being depleted with the sight of everyone worrying so much about her. "What if I didn't have to learn that form?"

"No. You have to practice it no matter what," Tanjiro said, his voice breaking on every fucking word. "And if you hurt yourself, I'll take the blame."

"No!" Zenitsu cried. It came out as a bloodcurdling scream accompanying uncontrollable sobbing. "I'll take the blame!"

Hayami picked up her sword, trying to fight the urge to quit - the urge to lay down and cry. She held the fist of the hand that was not grasping her sword to her heart as she wore a traumatized expression. Her teeth were clenched and she was fighting back tears. But this is something she had to do. She could not give up now - not when she was so damn close to practicing and getting a feel for her final form. No matter what it took, she sniffed and wiped her tears with the sleeve of her Demon Slayer uniform.

Hayami grasped her sword, tears in her eyes, yet she wore a determined expression as she prepared for her final form. She closed her eyes and practiced Total Concentration Breathing, trying her very best to tune out whatever was going on around her. Even though it seemed impossible, she believed in her heart that she could do it. And that she did.

"Twelfth Form: Ice Dragon!" Hayami called out. Summoning all of her strength into one blow, she let out a beautiful attack that resembled a dragon made entirely of ice. "You might wanna see this, guys! I did it! I really did it!"

Tanjiro and Zenitsu opened their eyes, tears now welled up in their eyes as they watched its beauty. The beauty was enough to make them cry again, but this time, it was not because they knew Hayami was gonna "die", but because of the sheer beauty of everything. Nezuko, too, was in awe. And who could blame them? It was a stellar attack that not just anyone could pull off. And Hayami did it. She really did it.

But then she fell unconscious to the ground and would not wake up regardless of Tanjiro's, Nezuko's, and Zenitsu's efforts.

"Is she…?" Zenitsu sobbed. "Dead?"

Inosuke showed up, jagged katanas in both of his hands.

"Where the hell have you been?" Tanjiro said. "We got married and Zenitsu finally had all of his dreams come true. First was that he got married to Nezuko, second was that he got married to me, and third was, you can probably tell what."

Inosuke removed his boar head to take a better look. "So, this is the result of demon and human sex," he said. "Interesting."

"What the hell!?" Tanjiro said in a nervous fit. "Y-you can't just say that so casually, you know!"

"What did I say wrong? Zenitsu had sex with Nezuko, didn't he? Good for him. Maybe you should have sex with him." Inosuke said. He turned to Zenitsu. "Wanna try it?"

Zenitsu and Tanjiro blubbered incoherently with their faces flustered red like the gay tomatoes they were.

"It seems that she's a Demon Slayer. And what's this? Ice? Can't say I've heard of it myself," Inosuke said. He kicked Hayami. "Get up, dammit! You seriously can't be dead now!"

"Inosuke, wh-what the hell are you doing!? You can't just kick a girl like that!" Zenitsu cried, still holding the blush from what Inosuke said not too long ago.

"She's your daughter. And I don't give a shit," Inosuke said. "A person is a person, no matter what gender they are. I kick and fight whoever I want. I don't care if they're a boy, a girl, or anything else."

"When you say 'anything else', what do you mean?" Tanjiro asked.

"You seriously didn't know…?" Inosuke said. "Never mind. There are other genders. Don't be so ignorant, Tanjiro."

"I'm not fucking ignorant! You're the one who's fucking ignorant!" Tanjiro cried. Just like Zenitsu, he was still blushing from Inosuke's comment on them to have sex with each other.

Inosuke smiled, putting his boar head back on. He shook Hayami as hard as he could. "Wake up! Wake up! Wake up!" Turning towards Tanjiro and Zenitsu. "What the fuck did you do?"

"She was teaching herself and then she practiced with the final form and passed out!" Tanjiro and Zenitsu cried. "We didn't do anything! We swear!"

Inosuke crossed his arms and continued kicking Hayami. "She seems like a strong girl. She'll wake up in no time."

"But she said…," Tanjiro said .

"What did she say?" Inosuke said, kneeling down beside Hayami and continuously slapping the young girl across the face.

Zenitsu watched in horror. "How dare you ruin my beautiful daughter's face with such marks? Every girl has beauty, even if she is born with traits from you as well as your sexy wife! Hurting a girl is uncalled for!"

"Like I said, gender doesn't concern me," Inosuke said. "And like I said, I can sense that she's strong. If she gets the recommended amount of rest, she'll be able to fight in no time when the time comes."

"I hope you're right," Nezuko said, looking solemnly down at the daughter she bore.

Tanjiro smiled at Zenitsu, his eyes telling it all. "In the meantime, wanna get into my bed?" he said.

Zenitsu smiled. "Of course I do! Why wouldn't I?" He rubbed his face against Tanjiro. "You're so handsome, Tanjiro-kun. Just as beautiful as Nezuko-chan."

Tanjiro blushed. "I-I wouldn't say that. My sister is pretty cute," he said. "And I'm not as handsome as you think."

"Aww Tanjiro-kun, don't be so modest!" Zenitsu said, running around Tanjiro.

"Zenitsu, this is all uncalled for! If you wanna do this, just come on!" Tanjiro said impatiently.

"OK, OK! I'm coming!" Zenitsu said, running after him.

* * *

Tanjiro lay down on his bed. "I've gotta say, I've never shared my bed with anyone other than Nezuko," he said.

"You're a good older brother! I wish I had siblings, but I was born alone!" Zenitsu said, sobbing. As he sobbed, his snot rubbed on the sheets.

Tanjiro tried to hide his disgust, but the expression still came regardless. He quickly got rid of it before Zenitsu could notice. "Just don't cry too much on the sheets," he said after clearing his throat.

Zenitsu sniffed. "I-I'll try," he said, wiping his tears and snot with the sleeve of his haori.

Tanjiro blushed. "I-i-if th-this is g-g-gonna work, then we need to… remove our clothes," he stammered.

Zenitsu blushed, his face fully red like a tomato. "G-get n-n-n-naked!?" he cried. "I-i-in front of…in front of YOU!?"

Tanjiro blushed like a tomato as well. He could not imagine it more. This would be a disaster for someone who was embarrassed to just be seen in his boxers.

"Are you getting the same feeling as I am right now?" Tanjiro asked.

"Wh-what feeling is that exactly?" Zenitsu said.

"I'm not ready… and quite frankly, I don't think I'll ever be ready for real… well, activities…. if you get what I mean."

"I don't think I do," Zenitsu said.

"I'm not ready for real sex, Zenitsu! And I don't think I ever will be!" Tanjiro cried with his eyes closed to add to his embarrassment. He blushed, his eyes now open. "D-do you think if we… don't take off all our clothes… it could still work?"

Blushing all over his body, Zenitsu nodded with a smile that was in between nervous and excited, as Pinkie Pie would describe as "nervouscited".

Both boys, blushing uncontrollably and all over their bodies like full-body tomatoes, shielded their eyes from each other as they stripped down to their boxers.

Once finished, Tanjiro and Zenitsu faced each other, the two still having their full-body blushes. They gulped.

"I'm scared…," Zenitsu confessed.

"I'm terrified," said Tanjiro.

An awkward silence followed. Both Tanjiro and Zenitsu took turns gesturing towards Tanjiro's king-sized bed.

"Uh… you go first," Zenitsu said.

"N-no, after you!" Tanjiro said with a nervous smile on his flustered face.

"No, no. I-it's your bed. After you," Zenitsu said.

"A-after you," Tanjiro said with a nervous chuckle. "I insist!"

"N-n-no. After you," Zenitsu said.

"I-I insist. After you, Zenitsu," Tanjiro said.

"A-after you," Zenitsu said, pushing him onto the bed.

Tanjiro chuckled, both nervously and genuinely. "L-looks l-like you g-got me, Z-Zenitsu," he stammered. "Good job."

Zenitsu blushed. "I-I d-didn't m-m-mean too!" he stammered. "I-I'm so sorry, Tanjiro! P-please forgive me!" He started crying.

Tanjiro embraced Zenitsu and made the first move. "Shh, shh. Don't cry. It's OK."

"Wh-what th-the h-hell a-a-are y-y-you d-doing, T-Tanjiro?" Zenitsu said, utter fear and anxiety racing over him.

Tanjiro closed his eyes, blushing as he rubbed his privates against Zenitsu's.

This caused Zenitsu to force his eyes closed. He just couldn't bear to keep them open anymore. He could not see where this was going for the life of him. It would kill him if he continued to panic as the blushing got more and more intense. He let his fears fly right behind him as he rested his head on Tanjiro's bare chest.

Taking a few deep breaths, careful not to unleash his Thunder Breathing by accident, Zenitsu engaged in the rubbing.

That night, Nezuko and Inosuke entered the room. The boys were now sleeping together happily, which made both her and Inosuke smile. As to not disturb them, Nezuko proceeded to make herself a bed on the floor.

"Why don't you sleep with them?" Inosuke said. "Haven't you slept in your brother's bed all your life? And aren't you married to Zenitsu?"

"Not all my life. In fact, I never slept in his bed. But as siblings, we never really wanted to be apart. Even now, the familial bond we share is so strong that we don't mind sharing a room with each other," Nezuko said. "But it would be uncomfortable if I slept with any of them."

"Makes sense," Inosuke said. He looked over at Tanjiro and Zenitsu, one in teal boxers and one in yellow boxers. "Looks like these two actually did what I suggested."

At that, he also set up a bed on the floor. "Goodnight, Nezuko. Goodnight, Tanjiro. Goodnight, Zenitsu." He looked at the still unconscious Hayami, who was now lying in her own bed. "Goodnight, Hayami. Hopefully you recover soon."
