"Holy shit!"
"Oh fuck!"
"What the hell...."
Yushirou, in his fury, had transformed and was angrily chasing a poor demon slayer through the courtyard.
The pillars and some of the other lower ranked demon slayers were watching in horror.
Black scleras, golden irises, a pair of horns and his hands were turned into monstrous claws as he hissed threateningly. Tamayo was running after him frantically.
The demon slayer was screaming in terror as Yushirou snarled, "You filth! Don't look at Tamayo-San with your lecherous eyes!"
Tengen was looking at him thoughtfully before he picked up a worried Tamayo and loudly said, "Maybe I should take Tamayo-San as my fourth wife."
Yushirou's head snapped back so fast, blood poured from his neck. "Excuse me?"
"I was joking," he said as he put her down and Yushirou glared at everyone, making sure Tamayo was fine even though nothing had happened.
"By the way," Tengen asked, "do all of you have demonic appearances like that? I thought you had human looks."
"We do. We just hide the demonic appearances." Tamayo said.
"Can you show me?"
"How barbaric! Tamayo-San doesn't have listen to you monkeys——!"
"Yushirou."
"Yes, Tamayo-San?" A smile spread across his face innocently.
Tamayo said, "It's fine but transforming can be quite... unnecessary for someone like me. Besides the point, mine is not necessary until I'm in a fight."
She looked up at the sky and then said, "It's almost sunrise. Yushirou and I must go now, please excuse us."
They quickly left.
Over dinner the next day, Tengen asked to see their transformations.
Tanjirou looked at him in slight confusion but Akaza shrugged. "Yeah sure."
"If you want."
"I don't mind but can I ask why?"
"Our demonic appearances? What for?"
The other pillars looked interested and the demons complied, though somewhat hesitantly. There were some restrictions but they didn't mind because the pillars wanted to see.
Rui's skin turned white as snow as his hair turned silver. His sclera was red as his cyan eyelashes fluttered. The birthmarks turned a startling red. He looked cold and most of all, powerful.
"Ooh! Look scary!" Instructed Tengen and Rui paused.
"Um, grr." Rui made a clawing motion and showed his fangs. He received a hug instead of fear.
Akaza turned just as pale, white enough that he looked like snow, with patterned scleras and pink hair with blue stripes all over his body. He grinned and they shivered.
Sabito's hair lengthened and a pair of bunny ears appeared on his head, flopping over his head as tassels grew, lengthening and swinging like weapons. His skin was a startling grey and his sclera was black with an extra pair of eyes. He looked similar but not to the hand demon he defeated.
Giyuu gave a detectable shudder as Sabito blinked his four eyes.
Tamayo didn't transform because it spent her too much energy just to show off but Yushirou didn't mind, turning into some sort of creature with bear like paws and a pair of horns.
Nezuko hesitated.
The demons didn't prompt her and said, "Tanjirou and Nezuko shouldn't transform unless necessary."
"No, we can do it," Nezuko said and then slowly, vines grew across her skin and her eyes turned feral, her fingers sharpening as she growled. A horn grew from her temple as her hair started to shift.
The power excluding from her exceeded that of even Akaza's and Sabito's.
She growled and then snarled as her eyes shifted uneasily.
Sanemi frowned. "Nezuko?"
She made a noise. Not once did she speak after that. She sullenly stood by Tanjirou's side, who laughed and stroked her hair.
"Sorry, Nezuko loses her human qualities when she transforms. If she gets too excited, she can lose control. It doesn’t happen often, so better safe than sorry.”
Tanjirou smiled and then smoothed a band over her hair. The other demons didn't interrupt, instead, answering questions.
Shinobu and Tengen didn't stop firing off multiple questions at all before Obanai looked at Tanjirou.
"What about you?"
"You wouldn't want that."
They froze and a strange feeling crept up their spines.
Mitsuri was the next one to ask. "Why— why's that?"
Tanjirou smiled in a reassuring way. "It's nothing, but usually the demons around me will start to panic. Also, I've been told my transformation is unsettling."
"We don't mind!" Kyoujorou said and Tanjirou pursed his lips.
He really looked reluctant to show them but after a long time, he was convinced, but he would only transform for two minutes.
Instantly, pressure forced them down and the demons knelt as Tanjirou transformed. His whip like tentacles that grew from his back stroked the floor and he stared coolly at them.
His eyes were turned to red slits and flame like patterns spread through his face. He smiled and the fangs in his mouth were accentuated.
The demons and demon slayers all felt the same thing: fear.
His face was uncanny to Muzan's and Ubuyashiki's. He could've been their triplet.
"See?" His voice was a rippling brook that held a hidden edge to it. "People are usually very uncomfortable when they see me."
"What... the fuck." Sanemi panted and tried to look up.
Tanjirou changed back and the pillars all thought the same thing: Thank god he's on our side.
His power was enough to rival and perhaps even surpass Muzan's.
"How'd you get that much power?!" Shinobu asked in an almost fervent curiosity.
Tanjirou laughed awkwardly, the same old kind Tanjirou.
"Oh. I was chosen as Muzan's next heir. He tried to turn me into the next demon king the moment he realized that Yoriichi could kill him. So in a moment of panic, he accidentally chose me."
They all froze.
"What the fuck?!"
Only the demons were left unfazed.
“You’re lying!” Sanemi said as he grabbed Tanjirou.
Wide eyed with worry, the demon said, “I’m not lying. I was created before Tamayo. Both Nezuko and I are one of the oldest living demons. Muzan chose me because of my connection with Yoriichi and Nezuko, who broke his curse.”
“Curse?”
All of the pillars were desperate to soak in any extra knowledge to make this whole thing better.
Tanjirou looked slightly weirded out and then he sighed and said, “I knew I shouldn’t have transformed.”
“No need! It was a great decision!”
“...”
“...”
“...”
————————————————————
Nezuko laud there in Mitsuri’s arms in the size of a child, a bamboo muzzle in her mouth as she stayed in her demon transformation.
Sanemi tried not to be jealous but it honestly took him a bit of a struggle.
Nezuko chirped noises as Kyoujorou and Tengen tried to convince Tanjirou to transform and train with them.
“I won’t! I won’t transform in front of you anymore!” He screamed as he dove into Mitsuri’s arms and shrank like Nezuko. Both of their pouting faces glared at Tengen and Kyoujorou.
Both of Tengen and Kyoujorou nearly melted from the double cuteness.
Mitsuri joined.
Sanemi wanted to die because he was starting to melt from the cuteness too.
“Cute~~~!!”
