[A/N] This is my first fanfiction ever so don't expect much. Also, there are going to be deviations from canon and lore. Specifically during Act 3. And there won't be much use of RbD here than canon. I think that's everything, so enjoy!

Where are we?

Yasuda Toshio, a 18 year old boy who is begrudgingly walking out of the bus stop with his 16 year old sister, Fukada Toshio, on his back..

" You know you are old enough to walk now…" Yasuda mumbled under his breath.

" Oh no, I just want to annoy you!" Fukada exclaimed.

" Of course you do." Yasuda then slipped out his phone and dialed a familiar number.

Riinngggggg, rinnggggg

As soon as the phone picks up, both of us scream the same thing-

" HELLO LOLIMANCER SUBARU!"

" Ahhhh! Gah- Oww, my ears are ringing from that!" A loud thud could also be heard. Subaru has fallen down.

" You ok?" Fukada questioned.

" Noooo! Give me a minute." complained Subaru.

Yasuda " You're fine! Stop complaining!"

Subaru " Ugg, I'm not complaining!"

Yasuda " Ya right, like I believe you."

Subaru " Well, anyways. Why did you call?"

Yasuda " I just want to check when you are coming back."

Subaru " Oh, I should be back in a month."

" Good, It's been 4 years!" Fukada butted in.

Subaru " These have been the slowest 4 years ever! I can't wait to eat your food again."

Yasuda " We've been improving, living alone is tough."

Subaru " Oh, is there any info on your parents' mysterious disappearance?"

Yasuda " Unfortunately, no. It's like they vanished into thin air."

Subaru " Weird. Well anyways, I got to head back! See ya later."

The phone soon hung up and we continued.

Yasuda " Sis, can you get off now?"

Fukada " Nope-!"

Without warning, we found ourselves in a completely different environment than before.

Yasuda " HUH?"

Fukada " W-where are we?"

Yasuda & Fukada " Uhh…"

Soon, everything became clear.

Yasuda " I think we're in another world."

Fukada and Yasuda blinked multiple times and slapped themselves to make sure that they weren't dreaming. They looked around to see a multitude of things, carriages pulled by big lizard-type animals, demi-humans, and an unknown language written on the signs.

However, while they were looking around. Yasuka spotted a familiar figure in an orange and black tracksuit.

Yasuda & Fukada " Subaru?"

Yasuka carried Fukada and himself towards the familiar-looking boy.

Subaru " HOLY SHI-"

" Shut up and don't embarrass us!" I quickly scolded Subaru.

We shake Subaru and drag him to an alleyway.

Yasuda " What were you thinking?!"

" Huh? Yasuda? Fukada? YOU'RE HERE TOO? YESSS! WE'RE TOGETHER AGAIN!" Subaru quickly hugged us, making Fukada lose grip and backplant into the ground. When Fukada tried to sit up, a red-eyed blond petite girl fell from the roof and landed straight into her.

Fukada " FUCK! OWWW"

Petite girl " Ugg, I can't be here any longer. Bye!"

Fukada " HEY!"

Thief 1 " Hey! You three! Give us everything you have!"

Thief 2 " Play it safe, we won't hurt you otherwise."

Thief 3 " Ya! What they said, you don't want to get stabbed right?"

Sure, we don't want to get hurt. But Fukada and I learned some self-defense tricks. So we have a few tricks up our sleeves, but for now…

Yasuda " GUARDS! WE'RE GETTING ROBBED!"

Fukada " What a way to deal with this situation."

Thief 1 " Hey! What was that for?"

Thief 2 " No one is going to help~you!"

? " That's enough!"

Flying from above, a red-haired man in a red-white robe flew down from the sky and landed in front of us.

Thief 3 " Red hair… Dragon sword… It's Reinhard Van Astra! The Sword Saint!"

Thief 1 " Fuck this! Let's go!"

Reinhard " Huh. Well, it looks like they're gone."

Fukada " Scaring thiefs is better than hurting them sooo…"

Yasuda " Good job!"

Reinhard " Even though I didn't do much, I technically saved you, so I'll take that compliment. What are your names?"

Subaru " I'm Subaru Natsuki!"

Fukada " I'm Fukada Toshio!"

Yasuda " And I'm Yasuda Toshio."

Reinhard " Oh? You two siblings?"

Fukada " Yep!"

Fukada jumps back on Yasuda's back and rests her head on Yasuda.

Yasuda " You still act like a child even though you're only two years younger."

Reinhard chuckles a little when a girl in a white dress and elf ears runs towards us.

? " Oh hey Reinhard! Have you seen a blonde petite girl? She stole my insignia."

Reinhard " Oh hey Emilia! Nope, but that insignia is important so I'll help."

Fukada " Oh, her. She's the one who fell off the roof and landed on me."

Subaru " That was pretty funny."

Yasuda " Agreed! But back to you, we can help. I have a few ideas that could narrow it down."

Emilia " Really? Puck, what do you think?"

Suddenly, a white floating cat popped up beside her. Noting that this is a fantasy world, it is probably a spirit of some kind.

Puck " I sense no malicious or ill-intent, so we're fine in that regard."

Emilia " Ok, as you might've heard. My name is Emilia, what's yours?"

Subaru " Subaru Natsuki, but right now. It's just Subaru!"

Puck " Ok Just Subaru!"

Subaru " Heh, I like you!"

Yasuka " Well… I'm Yasuka-"

Fukada " And I'm Fukada-"

Yasuka & Fukada " And we're the Toshio siblings!"

Subaru " Your introduction still needs a lot of work."

Puck " Siblings? Ooh, this is going to be interesting. I like you guys."

Reinhard " For two seemingly dysfunctional siblings, you have perfect synchrony."

Yasuka & Fukada " Thank you- Wait! That's bad!"

Subaru " It happened again!"

Subaru is barely keeping it together, he really doesn't want to get to the bad side of them.

Emilia " Let's go~Pfft!"

Yasuka " Ok then, so there are two ideas I have."

Yasuka " First, we can say that the culprit in question will probably be in the slums, it doesn't make sense for a well-off citizen to steal something."

Fukada " Ah, I got the second one! If they were in the slums, they probably have a bargaining market there to sell stolen goods. The culprit probably wants to sell your insignia so they can survive."

Subaru " Or~ they were assigned by a seller to steal the insignia for some money."

Puck " That- makes sense!"

Reinhard " I'm impressed! I wouldn't have thought of that!"

Emilia " Same, but either way, we should hurry. If Subaru's theory is correct, they will probably kill them after the exchange."

Subaru " Let's go then!"

The group exited the alleyway and headed to the slums. Puck quickly struck up conversation.

Puck " You don't look like you've been in Lugnica before, where did you come from?"

A question that the three feared, but Yasuka was prepared!

Yasuka " We come from the east, we were going back home when we mysteriously teleported here. Presumably magic. Though we personally haven't had much experience in magic. I wish I had more details to share."

Fukada " From what I've seen, Lugnica has a different written language and possibly different currency from our homeland."

Puck " Isn't The Great Waterfall east of here? Though from your story, I presume you have no idea what that is."

Subaru " No clue."

Emilia " That's- troublesome! You have no clue where you are and you can't go back home!"

Reinhard " Not to mention, your parents have no clue where you are!"

Subaru " Mom… Dad… I never got to say what I wanted to say…"

Yasuka " Our parents disappeared a couple of months ago…"

Emilia " Really? Maybe they shared the same fate as you! Whipped here with no clue of their situations…"

Fukada " Maybe…"

Subaru " I don't think anyone uses whipped anymore, Emilia."

Reinhard " What are you going to do after this?"

Fukada & Yasuda & Subaru " We have no idea!"

Subaru " We'll go with the flow!"

Fukada " That is what we do!"

Puck " You do know that's dangerous?"

Yasuda " We know, but they don't really care."

Emilia " You need to be cautious!"

Puck " Lia's right! But your mentality can make things enjoyable."

Reinhard " Hate to interrupt, but we reached the slums."

Yasuda " Hmm. Reinhard, you should watch from a distance. We don't know how the people here will react to you. We can call you if there's any trouble."

Reinhard " Good call."

Subaru " I'm taking a wild guess here but I think that building on the hill is our goal."

We look towards said house and catch a glimpse of blond hair entering the building.

Puck " Definitely. Let's go!"

We run towards the building in question and I notice a woman in black entering the building. With two knives on her.

Yasuda " Guess you were right, Subaru!"

Subaru " Then let's hurry!"

After 5 minutes, we finally reached the building and entered. To see Reinhard engaged in combat with the woman.

Puck " The bowel hunter Elsa, I never expected you to be here."

Elsa " Oho? A spirit? And one that knows me? I'm looking forward to seeing your bowels!"
