#reader is a little...

Tanjiro, Zenitsu, and Inosuke were in no way new to hectic things. Hell, every day with them was an adventure! But this day Zenitsu was absent due to the stomach flu, so it left Tanjiro with Inosuke.

Or so the young baker's son thought, but he couldn't find the wild friend of his. Tanjiro was confused since they were by this time usually talking and heading towards their first class of the day. The young man started to get worried that Inosuke had also gotten stomach flu, but a sudden yelling caught his attention.

"Stop right there!"

"Hold it!"

"Oi, stop!"

Tanjiro turned to look and to his confusion, he saw Uzui-sensei, Tomioka-sensei, and Shinazugawa-sensei run after Inosuke.

"Nyah ha ha ha!" The young man laughed as he ran, "Just try and stop me!"

"I- Inosuke!?" Tanjiro gasped as he saw his friend run towards him… With a young woman thrown over his shoulder?!

"I- Inosuke-!" The baker's son was saying when he was suddenly caught by his friend and thrown on his other shoulder, "Janpiro! Good, come with me!"

"Eeh!?"

Finally, the two of them managed to lose the teachers who were after them, or rather, after Inosuke, but they had also left the school grounds and arrived at the park by the river close to the school.

"Nyah ha ha! I told you we would lose them!" Inosuke laughed and Tanjiro looked at his friend, ready to scold him a little, but then he noticed the woman, you, looking at him with big pretty eyes and a small smile.

"O- oh, greetings! Are you perhaps a friend of Inosuke?" The young man asked and you brightened up, but as you were about to reply, Inosuke called, "She is my new servant!"

"Inosuke, you can't just grab a girl and make her your servant!" Tanjiro cried out, "If Zenitsu knew what you were up to, he would freak out…"

"Monitsu isn't here, is he?"

"Still…" The young man sighed as he turned to look at you and smiled, "Anyway, what is your name?"

"I'm Romu!" You cheered happily and saluted them, "And I'm new!"

"Ah, I see," Tanjiro nodded while Inosuke shouted, "She is my new servant!"

"I'm new!" You nodded and the kind young man looked at you, "Are you perhaps new to Kimetsu Academy?"

"I'm…" You hummed thoughtfully, "I'm new!"

"Ah, anyway…" Tanjiro sighed as he looked at you and smiled a little, "What were you doing that made the teachers chase after you?"

"I was snooping!"

"Snooping?" The young man repeated and you nodded, "Yes! I was trying to find some dirt about Director!"

"Eh!?" Tanjiro was shocked, "Who told you to do that?!"

"I-!" You were saying when you stilled and then frowned, "I… I can't remember! They had black hair though!"

"That could be literally anyone…" The young man sighed and Inosuke looked at his friend, "Wait, who is the Director?"

"Principal's husband, Inosuke."

"Who?"

Tanjiro sighed as he attempted to remind Inosuke that the director had handed them the winning tickets during the Halloween competition.

While Tanjiro and Inosuke talked you noticed a group of small kids playing nearby with a ball. You felt tempted to go and join the kids and you smiled as you rushed towards them… But then one kid threw the ball too high and too fast and a small girl went running after the ball, only to run straight to the road where a car was heading-!

Suddenly Tanjiro and Inosuke heard screeching, followed by a child's scream, and they both looked in shock to see how a car had stopped in the middle of the road, but what horrified them was the sight of you lying on the ground before the car.

"R- Romu!" Both young men shouted as they ran to you and the car's driver stepped outside of his vehicle, "Holy shit, she came out of nowhere!"

"Romu, are you alright!?" Tanjiro touched your shoulder and you glanced at him, opening your arms, showing them the small girl you had saved.

"I'm okay," You nodded as you looked at the girl crying in your arms, "Girl okay?"

"Let me see," The young man picked up the girl and looked all at her, and to his relief, she was perfectly fine, "She's okay! Just scared.

"Mimi!" Someone shouted and the students turned to see the girl's friends running at you guys, "Is Mimi okay?"

"Yes, she is thanks to Romu!" Inosuke exclaimed as he moved to help you up, but Tanjiro tried to stop his friend, "Inosuke, wait, we have to call an ambulance-!"

"No need!" You smiled as you bounced up like nothing had happened, "Car didn't hit Romu! Only nudged!"

"How-!" The two young men were shocked, they were pretty sure you had taken a hard hit, but you didn't look like it, and neither did the driver's car.

"Thank you for saving Mimi, big sis!" The kids gathered around you and you laughed with a huge happy smile, "I'm glad!"

"Ah, our ball!" One kid cried out and you all looked down to see their ball in the water below the bridge.

"Romu will get it!" You cheered and before anyone could stop you, you climbed off the fence and jumped into the water below… But when you didn't resurface, Tanjiro and Inosuke cried out after you in worry.

"Romu!"

"Shit, I can't see her!"

"Over there!" Finally, you surfaced, but you were only kicking and trashing your hands around instead of swimming smoothly. It didn't take a genius to realize that you weren't doing well and the boys were alarmed when they saw you go below the surface again.

"R- Romu!" Tanjiro and Inosuke called, putting their bags down and they were ready to jump after you, but suddenly, there was a blue blur that flashed next to them and the boys watched how their P.E. teacher Giyu Tomioka jumped after you.

"T- Tomioka-sensei!" Both young men called after their teacher and watched how he went below the surface… And finally, he resurfaced with you in his arms.

"Romu! Tomioka-sensei!"

You coughed as Tomioka held you above the surface and swam, taking you to the shore where Tanjiro and Inosuke rushed to you, alongside with the kids whose ball you had gone to retrieve.

As soon as you were on the safety of dry land, Tomioka let you go and you kept coughing, "Gah, Romu got water in her nose…"

"Thank God you're safe!" Tanjiro cried out and Inosuke copied his friend, "That was dangerous!"

"Big sis, are you okay?" The kids asked and you coughed one last time before smiling, "Ha ha, I forgot I don't know how to swim!"

How can someone forget something so important!?

"Are you alright?" Tomioka-sensei asked and you nodded, "Yes! Thank you for saving Romu!"

The teacher nodded, but before anyone could say or do anything else-!

"Romu!" Someone called and everyone turned to see a woman running at them. Tanjiro and Inosuke were stunned, she looked a lot like you.

"Mom!" You called as the woman dropped on her knees in front of you and grabbed your head to check you from every angle there was, "Oh my baby, are you okay?"

"Romu is fine!" You nodded with a big happy smile and your mother sighed, "You're gonna kill me one of these days, child!"

"Excuse me, but are you by any chance Romu's mother?" Tanjiro asked and your mother nodded as she looked at the two young men, "Yes, and you are?"

"Romu's new friends!" You cheered and Tanjiro and Inosuke smiled as they introduced themselves to your mother, "It's a pleasure to meet you, ma'am."

"Oh, what nice young men you are," Your mother smiled and then she turned to look at the P.E. teacher, "And thank you for finding my child."

"It was no trouble," The teacher nodded and Tanjiro looked at him, "Tomioka-sensei, how did you know to keep searching us?"

"I got a call from Romu's mother, telling us that she was a new student and had gone missing on her way to school," Giyu explained and your mother bowed to Tanjiro and Inosuke, "Thank you so much for keeping my daughter safe."

You blinked as you watched your mother bow so you copied her and bowed to the young men who had been there for you, "Thank you for helping!"

"Please raise your heads," Tanjiro smiled, "It was Tomioka-sensei who saved her from drowning."

"Thank you," Your mother bowed to Tomioka also before straightening her back and sighing.

"Romu is too kind-hearted and wants to help and befriend people wherever she goes…" Your mother shook her head, "Because of this, people tend to take advantage of her naive nature… Honestly, she takes too much after her father."

"My dad is special!" You laughed and your mother sighed, "I swear, this kid would lose her head if it wasn't attached to her, or give it away if someone told her to…"

"Please don't be mad…" The kids from earlier frowned, "She saved Mimi from being hit by a car!"

"Did you do that?" Your mother looked at you and you smiled, "I just did what dad would do!"

"Of course you would." Your mother shook her head and then looked at Tanjiro, "Thank you for helping her."

"Actually, it was Inosuke who helped her first," Tanjiro said and Inosuke smiled proudly, "Nyah ha ha! I've decided! The great Inosuke will look after Romu!"

"You don't need to-!" Your mother was saying, but you smiled as you got up and hugged Inosuke, "I like him! Inosuke is so kind to Romu!"

"Are you alright with this, sensei?" Your mother asked and Giyu nodded, "Don't worry, these are good boys. There isn't a bad bone in them."

"In that case…" Your mother nodded as she looked at all three of you, "Do you know what you are getting into?"

"We don't mind!" Both young men smiled, "I bet Romu would like my younger sister and our friend Zenitsu!"

"If you're sure…" Your mother sighed as she smiled, "Don't make them worry too much Romu!"

"I won't!" You smiled as you hugged Inosuke tighter.
