Little Demons to Totty Demons

[Temmiedasithlowd]

Nezuko slept the whole way home a small bit of drool starting to drip down her chin as she reflexively began to suck her thumb in her slumber.

———————————

“Hush you’ll alert the whole house, listen you’ve been hit with a blood demon art that made you a baby, I don’t know if you’ll turn back but I’m gonna call someone up here and up I’ll tell them your gonna be gone for an undetermined amount of time and then I’ll start biding time till I can find a way to turn you back.” Guytaro explained.

Tanjiro slipped a pacifier into her mouth as he brought her closer to the butterfly house, hoping Ms. Shinobu could help.

Daki stopped in shock as she realized what she now was. “Are you kidding me? I’m the most beautiful demon moon I can’t be a baby!.” She yelled before calming down, realizing her brother was right. “That makes sense, at least I won’t have to wear diapers like human babies.” She said not knowing how wrong she was.

[Temmiedasithlowd]

Nezuko cooed in her sleep as she sucked on the pacifier finding her brother’s chest very warm as she slept.

“Oh dear Tanjiro what have we here? Stressful day for her?” Shinobu asked knowing Nezuko got small when she was really exhausted or stressed.

—————————————

“Yeah no you still need them.” He said laying in her down and quickly powdering her before fitting her into a diaper. “Master Muzan says he has no idea how this affects you but just deal with it for now okay.” He said smiling to hopefully make her feel better after he trying reassurance from her big brother.

[Neran]

“Umm, no. She was hit with a blood demon art and was turned into this, I was wondering if you knew anything I could do about it.” He said showing her that Nezuko was now diapered to hammer in the point.

—————

“What?” She said as she was diapered. “Brother, I am the nosy beautiful demon moon! What will people say when they see I’ve been reduced to this! Remove this diaper this instant! I don’t need them!” She said as she stomped her feet. However, she was so loud she didn’t even notice the hissing sound coming from her or the yellowing of her diaper.

[Temmiedasithlowd]

“Oh I see well unfortunately I have no idea how to reverse a blood demon art like this, especially for demons so I’m afraid there’s not much I can do to help, but the girls would gladly care for her when your on a mission, even though it seems like she can still fight.” She said with a smile as she pet the sleeping Nezuko’s head.

———————————

“Daki stop yelling this instant.” He said getting a cold but not terrible tone towards her when she was yelling and getting upset.

[Neran]

Tanjiro sighed, but thanked her for her help anyway. Maybe he should check out the butterfly trio. They could help take care of her while trained or was recovering from missions.

———————

Daki immediately stopped as she realized there was nothing she could do. “Okay big brother.” She timidly before she realized her diaper was wet. After a few seconds of shock, she started crying, unable to deal with what was happening.

[Temmiedasithlowd]

Nezuko slept for quite a while before beginning to nudge and wake up letting out a yawn and rubbing her eyes as she looked up at her big brother. “T-Tanji.” She babbled with a whimper.

——————————————

“W-woah hey hey it’s okay Shh.” He said as he tried to calm her down as he got some changing supplies to change the soaked diaper.

[Neran]

Tanjiro brought his little sister to his face. “What’s wrong Nezuko?” He said as he began rocking her back and forth.

——————

Daki continued to cry. “Gyu! I dun like this diapee!” Her distressed state likely causing her to regress to more infantile use of words. “I shouldn’t be dealing with this! I’m upper six!” She said, not considering she wasn’t the true upper six.

[Temmiedasithlowd]

Nezuko kept whimpering before looking down at herself as she shifted her legs, which caused the diaper to crinkle and then she looked back at him kinda hoping he would check it.

————————————

“Come on Daki there’s no use crying it’s just making you even more upset, deep breathes little six.” He said as he gently bounced her in his hold to try and calm her down since he could change her while she was this upset.

[Neran]

Tanjiro realized what was going on. “Don’t worry Nezuko, let’s get you changed.” He said as he laid her down and untaped her diaper. He then wiped her lower half down before powdering her and placing a new diaper on her. “There, feel better now?”

——————

Daki slowly started to calm down. “P-please change me b-big brother.” She asked timidly before snuggling into her older brother.
