Help! I'm stuck in Demon Slayer! (Various x reader)

New family

It's quiet...too quiet. The dancers have their own horse carriages which you are thankful for since you didn't feel like walking. Now you and Leo are in the same carriage with the leader and short dancer. The four of you are eating dangos during the ride. As grateful as you are for saving your ass, it feels awkward to be around them. Especially since the two of them haven't stopped smiling. The leader turns to face you.

"May I ask for your names?" She asked.

You and Leo didn't understand a word she said.

"I'm sorry. We don't speak Japanese." You apologized. Inside you're comically crying. After years watching anime, you would think I pick up the language!

The shorter one turns to the leader. "Sister dear, these two are clearly not from here. I think we have to take it slow." She spoke.

"You're right, my dear sister. I'll try a different approach." Lilac eyes replied. The leader points at herself, "My name is Shinozaki Hanabi." She points at herself again. "Shinozaki Hanabi." Then she points at her sister, "Shinozaki Mei." Now she's pointing at you before pointing at your brother.

Now you finally get it. Let's hope you don't butcher the language. "Watashi no (Y/N) (L/N). Nice to meet you." You introduce yourself. You gently nudge Leo with your elbow to indicate it's his turn.

"W-Wata...sh..." Your brother is red in the face with embarrassment that he couldn't say it in Japanese. "Screw it! My name is Leo (L/N)! It's nice to meet you both!" He exclaimed.

"Nice to meet you, Leo and (Y/N)." Hanabi and Mei greeted in unison.

Mei turns to face you. "You understand Japanese a little?" She asked.

"Um...wakata?" You answered.

"Good, that's good." Mei smiles.

Then it got quiet again. Something tells me this is gonna be a long ride. Why couldn't they have a car? And why weren't you seeing any modern technology?

"You two speak English. Any chance you are American?" Hanabi asked.

You and Leo's mouths dropped.

"You speak English!?" You both yelled.

Hanabi's face flushed pink despite wearing white makeup. "My English is no good, but I understand you sometimes." Hanabi explains. "I know you and your brother are lost."

"Yes we are! Do you guys have a phone so we can call our parents?" Leo happily exclaimed.

Hanabi and Mei raised their eyebrows at him. "What is a phone, oneesan?" Mei asked.

"I don't know." Hanabi shrugged. "Forgive me, Leo chan. Phone is I don't know."

His smile falters and now tears are threatening to come out of his eyes. How can she not know what a phone is? Everyone around the world has one! Well except for the Amish. But still! That's when it dawns on you. People are wearing kimonos despite it not being a holiday, there are no outlets or any modern technology nearby, and no one knows what a phone is.

"What year is this?" You asked.

"We're in the Taisho era." Hanabi answered.

Your breath took a hitch. No fucking way you and your brother traveled back in time! But the proof is staring right at you. Plus the fact you went from a 17 year old girl down to a 14 year old. Now to cover your tracks to why you asked a silly question.

"So it is true that Japan goes by eras instead of the actual year! Sugoi! Sugoi!" You exclaimed.

"Leo mentioned something about their parents. Did something happen to them?" Mei asked Hanabi.
