PART 1/3

"So, where should we go today?" Koichi asked his cousins as he put the last of his stuff in his bag. "Nee-chan isn't going to come home until later, father is at the farm and mother is with nee-chan."

"Hm... mother and father are also going to return later than usual..." Yuichiro muttered, tilting his head to think of somewhere to go.

"Michi is with his boyfriend..." Muichiro, no. Michikatsu does not have a boyfriend, he's referring to Muzan. "And Yochii finally had the guts to ask Uta-san on a date... and that's today... uncle Heikichi and aunty Hitomo are going on a date later..."

"Man it's boring..." Koichi added as he sighed. "How about Tanjiro and the others, do you think they want to hang out today?"

"Let's find out." Yuichiro said as they all stood up and left their classroom to go to the high school section, where Neuko had run off earlier.

As Tanjiro was about to walk out of his classroom with Nezuko, Zenitsu and Inosuke, he heard his name being called. He looked over to the door to see Genya and Kanao walking over to the four of them. "Hey, Genya, Kanao!"

"Hey!" They greeted. "You guys are free today?" Genya asked as they all nodded. "That's good! Kanao and I are free today too! Want to hang out?"

"Sure!" Tanjiro said as the others nodded as well. They chatted and were about to leave their classroom when three sets of footsteps came running to them.

"LET US GO TOO!!" Three Koichi and the twins said in unison as they caught up to them. "We're free today and it's boring back home! Let us come too!"

"Sure! Let's go to the mall!"

═══*.·:·.☽✧ ✦ ✧☾.·:·.*═══

The group finally made their way to the mall as they looked around. They mostly spent their time in the department store, looking through video games and playing in the console.

Then, an hour into the store, they got hungry. They all made their way to a recently popular smoothy place. The whole place was packed with people but they were always told that the wait was worth it.

"Hello! Which flavor would you like?" The person said. This person had medium length hair, black fading to reddish gold, like the hair color was fading. On the tag it said KAZU1.

"What would you recommend?" Tanjiro asked as KAZU1 took the menu and showed it to him.

"Well, a lot of our flavors have been pretty popular lately!" KAZU1 cheered, pointing at a certain flavor. "The 'Flavorful Night' has been pretty popular with couples recently! Want to try?" KAZU1 asked with a sly tone, but was suddenly smacked over the head.

"Don't go recommend that to kids! ARe you fucking dumb!?" This time the person wore a blank mask. On their tag it said KAZU2. The kids assumed they were twins. And no, we're not twins."Anyway, you kids better pick something that will be easy for your age to get." KAZU2 pushed KAZU1 away, taking the menu from them. "Here, I would suggest something like 'Childhood Ruined' or 'Studying= Student+Dying'. 'Memes' have been pretty popular too."

"Those are..." Zenitsu squinted his eyes at the strange naming of the smoothies. "Interesting names..."

"U-um... do you have something.. More... normal?" Muichiro asked as he glanced over the wording of the menu. Some of them were 'Kageyama', 'Extra Tsukishima', 'Super Yamaguchi' and it was listed on the sports section. There was even an 'OyaOyaOya' and a 'HeyHeyHey' one and a super long name that had 'come to Shiratorizawa' along the way. Muichiro was sure it was a sentence and not a name.

"Well..." KAZU1 returned, taking the menu from KAZU2 and showed the children the 'new' section. "We have this new flavor called 'Nostalgia'. Those who bought it said that they would recommend!"

"Yup!" KAZU2 nodded in approval. "They say that the flavor really took them to their old days!" The children nodded in agreement as they all ordered one for themselves. "Alright, nine 'Nostalgia' coming right up!"

And so, after a minute or so, KAZU1 and KAZU2 finished their orders as they handed them one by one. After paying, the children left the store as they sat at a chair in the mall, they took a picture for memory's sake.

"Man... I wish nee-chan was here..." Koichi muttered and the twins nodded. "She likes smoothies."

"Nemi also makes smoothies sometimes..." Genya added.

"I saw Tomioka sensei making some smoothy that one time in the school cafeteria!" Tanjiro added with a little laugh. "He broke the machine." They all hollered, Zenitsu choking on his smoothy. "I saw him hide the machine."

"Smoothies..." Inosuke muttered. 'Mother makes some too...'

"I saw that Uzui-sensei on a date with his girls here before." Zenitsu said. "I'm pretty sure they ordered the 'Flavorful night one'."

"I wonder what kind of flavor that is..." Kanao trailed off, her eyes looking around as she saw a familiar figure. "Ah, look, it's Shinobu-nee. Let's go ask her." They nodded, still sipping through their drink, Inosuke finished his a long time ago. "Shinobu-nee!"

"Hm?" Shinobu looked at the group and tilted her head in confusion. "Excuse me... but who are you?" Kanao paused in her tracks, feeling as if someone just stabbed her. "Hm... you awfully look like my little sister you know!"

"U-um... what do you mean?" Kanao asked, Nezuko patted her back.

"Oh, Shinobu-chan!" Kanae came out of a store, holding a few bags as Shinobu took them from her. "Hm, oh, for a second I thought you were Kanao-chan!"

"B-but I'm..." Kanao stuttered, the Kamado siblings gave her their sibling hug.

"I see! They're the new transfers!" Kanae said, pointing to the nine students. "They transferred today! Hello, I'm Kocho Kanae, I'm in my third year! Nice to meet you!"

"I'm Kocho Shinobu, nice to meet you." Shinobu greeted with a smile. It was then that they noticed that Shinobu was wearing the middle school uniform.

"U-um... I'm Kocho Kanoao." Kanao said, hoping that they would stop their joking.

"Wow! You're named just like our little sister! That's such a coincidence! You should meet her sometime!" Kanae exclaimed and the others were very confused.

'Kanae-nee is wearing a uniform?' Kanao thought. 'And Shinobu-nee is wearing the middle school uniform?'

"Hey! Why don't we invite them too!" Kanae suggested but Shinobu protested. "Don't worry, Shinobu-chan, I'm sure (Y/N)-chan wouldn't mind!"

Koichi and the twins stepped forward. "W-wait! Nee-chan! You're talking about nee-chan!?" Koichi asked. Kanae and Shinobu tilted their heads as they stare at Koichi then at the twins behind him.

"You three awfully look like her brother and cousins..." Shinobu muttered.

"Anyway! Let me call her!" Kanae moved away to take a call, leaving Shinobu with the children.

"Shinobu-n-san..." Kanao called her, she's beginning to get an idea of what was happening. Shinobu hummed in response. "What's the date today?"

"Let me see..." Shinobu took her phone as she looked. "It's July 5 20XX."

The children's mouth jaw nearly dropped to the ground when they heard the year.

'W-we time-traveled!?' They all thought. They racked their brains as to what could've happened to take them back on time, or if there was even an explanation for the situation they're in. Shinobu watched in confusion as their souls left their body

"Hey..." Zenituse was the first to break the silence. He raised his drink, pointed at the paper that was stuck on the cup. "When I went there before, I took the 'Explodo Nerd', on the contents it said 'Brains 100%' and 'Anger Issues over 9000'."

"And?" Inosuke raised a brow. "What about it?"

"I was freaking smart for the whole day! And I was super angry too!" He said in a hushed tone. "You remember that one, don't you, Genya!" Genya nodded and told them that it was true. He was smart for one day without fainting but he was angry all the time. "Anyway, read the content."

The children nodded as they raised the drink closer and began to read through the contents.

Memories %%%

Family 20%

( ͡° ͜ʖ ͡°) 69%

Crackhead 420%

Satan Summoning - most likely

Mental stability - not likely, not ever

Time-traveling - D E F I N E T E L Y

Returning - ... ÓwÒ ...

They re-read through the contents again and again, passing their already empty drinks and reading through them. They all said the same thing.

"Good news!" Kanae soon returned with her cheerful smile. "(Y/N)-chan said it was okay!" The children just nodded slowly. "Great! Let's go then! (Y/N)-chan and the others are waiting!"
