Welcome! To the day of Halloween in the Astral Express!

And today we have!

March 7 Halloween costume being a beautiful Elf Fairy!

Next, we have Stelle! That uses the Trash can costume!

Next, we have Dan Heng! As Dan Heng! Cause he doesn't wanna wear any costume!

And then we have Y/n! Who is trying to wear a costume to look like Mr. Yang, but his hair is kind of too long so March tied his hair to a twin tail!

He even wears glasses too, as for the clothes he can't do really much! Other wearing his usual clothes but with a scientist lab coat and a scarf because they look cool

Y/n: " Well well everyone how has your journey been? I hope you are all fine and well " he tries mimicking Mr. Yang

March 7: " Ahahaha... Good acting, well then Mr. Yang may I ask where your walking cane is? "

Y/n: " Oh no... "

Y/n fix his glass up

Y/n: " It seems I have left my Walking stick back at the space station when I was having a robot fight with the great Madame Herta "

March 7: " Eh... So... Who won? "

Y/n: " Well I merely showed a small percentage of my true Robotic experience and created the super robot, so of course, I won! mwahahaha! "

March 7: " Y/n... I don't think Mr. Yang would laugh like that "

Y/n: " Yeah... The laugh is a bit too much like a villain laugh "

Welt: " Hmm... What this? You two seem to be having fun "

The real Mr. Yang appeared!

Y/n: " Why yes other me! I am Welt Yang! The smartest in this train! " says while using up the glass and covering his mouth with the scarf

Welt: " Hmm... Nice costume, but you look more like someone else than me, " he says as he pats Y/n head

Y/n: " Really? Who!? Who? Who? Is it Mr. Yang's girlfriend!? "

Welt: " Heheh... No, she was a family "

Y/n: " Oooooooh! Can you tell me about her? Then I can just be her! For my Halloween costume! Since Mr. Yang's costume is not working well... "

Welt: " Hmm... Well she was smart, a lot smarter than me, and she was also a really good dancer "

Y/n: " Ooooooooohhhhhhhh! "

March 7: " She must be amazing if she is smarter than Mr. Yang "

Welt: " Yes she is indeed amazing "

Himeko: " Oh my everyone is dressing up for Halloween Hmm~ "

March 7: " Ms. Himeko! Why don't you join as well!? "

Y/n: " Yes! "

Himeko: " Mmm... But I don't really have any costume to wear for this kind of occasion "

Stelle: " Miss Himeko! I wish to give an opinion on wearing some Teacher's uniform!! "

March 7: " Why teacher uniform... "

Stelle: " Because mo-Ms. Himeko would look good and sexy as hell! "

March 7: " Aren't you just down bad today... "

Stelle: " Yes I am "

March 7: " Well Teacher uniform would indeed suit Ms. Himeko "

Y/n: " Or maybe how about a knight-like costume! "

March 7: " Knight-like? Hmmm... I can't imagine how Ms. Himko would run around swinging a sword through "

Y/n: " But it would be pretty cool "

Stelle: " Cmoon Dan Heng, join us! "

Dan Heng: " No... I am not wearing any silly costume "

Stelle: " Just wear something like a Police uniform or something! Or maybe a Vampire costume! "

Dan Heng: " Why those specifically "

Stelle: " Because they are the less silly costume and I think it would suit you "

Dan Heng: " No... " he starts walking back to his room with Stelle following and keeps asking him to join in

Time skip brought to you with Blade looking cute

-------------------------------------------------------------

After a few minutes, Dan Heng joined the costume party as a Detective or something because there were no police uniform

And March took a photo of him who was trying to cover the camera

March then uploads it online and puts a description of what he is wearing for Halloween as an Officer

And a lot of comment

March 7: " Oh my... I just uploaded the pic but it seems a lot of girls already commented "

Y/n: " Really let me see! What they say! "

And so they read the comment

Comment 1: Oh wow! Such a handsome man!

Comment 2: I won't mind being arrested by this officer

Comment 3: Officer! I must confess to committing the crime of losing my heart to you!

Comment 4: Lol, Girls XD

Comment 5: Oh my~ I would love to be step on by him uehehehe

Comment 6: This gonna make me become a bi shit

The comment went more and more R18 as it went down which made March stop Y/n from reading

March 7: " Alright Y/n pose for me, I'll take a picture of you too "

Y/n: " Okay! "

And so I pose trying to make myself look smart!

March 7: " Nice! "

She uploaded it and a lot of comments appeared in just a few seconds

Comment 1: What a cute child!

Comment 2: Who's this little doctor

Comment 3: Where is my sack there is a child I need to get inside the sack!

Comment 4: There's a loli we must kidnap! To be head patted of course!

[ Comment 3 account has been terminated ]

Comment 5: oh shit! Did someone's account just get terminated

Comment went to a more dangerous route and more accounts got terminated and blocked

Y/n: " Alright I'm going out! Now to visit Captain Hook! "

Mr. Yang: " Be sure to come back before dinner "

Y/n: " Okay! "

And Y/n went to play with Hook and the other children

And they got scolded by Natasha for eating too much candy and trying to scare people by surprising them

Time skip brought to you with a meme

-------------------------------------------------------------
That night

Y/n came back from the express and was greeted by a cool robot!

Robot: Welcome back Y/n, did you have fun with the other children?

Y/n: " Woooooooaaaahhhhhhh! Mr. Yang that is so coooool! "

Welt: Ahaha... Say hello to Arahato one of the mechs I built when I was still working as an Animator

Y/n: " Can you do a cool pose! "

Stelle: " I want to see it too! "

Welt: Alright alright let me think of something

Mr. Yang thought something and then start speaking in a dramatic and cool voice

Welt: Tyrant of the false heaven! Witness the shattering of stars! Haaa!

Y/n & Stelle: " Uwoooooooooohhhhh! That's so coooooollll!! "

March 7: " Cool pose! " she said as she took pictures and uploaded them

A lot of kids liked it

After a few more poses

Mr. Yang takes off the costume and looks tired

Welt: " All right that's enough, I'm already not at the age to do this stuff "

Himeko: " Fufu~ well the others liked it thought "

After this, they all watch some scary movie

The next morning

Welt: " Y/n, March, are you both free today? "

March 7: " What's wrong Mr. Yang? "

Welt: " Madam Herta just sent me a message she wants to try something to find out about Y/n's past "

Y/n: " Ooooooh! I'm totally free today! "

Welt: " All right then let's go and visit her today "

March 7: " Let's go! "

And so they went to the space station

And March and Y/n got their blood taken

Although the researcher was a bit weirded out by my blood color...

Well it is Red but not entirely red, there was a bit of a weird yellow color...

Y/n: " So... What does my blood actually can help? "

Welt: " I believe this test is about trying to see if your blood DNA would have hmm... How do explain in simple terms... Ah let's just say your Blood has a special something that your parents also might have "

Y/n: " Okay...? "

Madam Herta: " Well it's not 100% work I'm just trying to see if we got a hit from our archive and find out who your parents are or whether there are records of you in this world, so don't expect much especially if your record was erased by someone "

March 7 & Y/n: "" Ooooooooh ""

After an hour of waiting for the result and hearing some researcher screaming and Madam Herta getting mad, it is finally done

Madam Herta: " All right it's done hmm... There is no record or hit for the pink girly "

March 7: " As expected... "

Madam Herta: " Now for Y/n... Hmm... This is pretty weird... "

Welt: " What's wrong? "

Y/n: " Is something wrong!? "

Madam Herta: " Ah no... Nothing wrong you didn't or well you got hit but you hit so many that I don't think of them is your parents "

Y/n: " I see... "

March 7: " It's fine! We can always try another way! "

March try to cheer Y/n up
----

While that happens Herta pulls Welt a bit far away from them

Welt: " Right we are far enough... I assume you did get a hit, but it's not a good one "

Madam Herta: " Indeed a member of the Genius Society... But as far as my knowledge goes she is missing and presumably dead, and what she researched is not exactly normal either but it is indeed an interesting topic to research on "

Welt: " I see... Please elaborate me on this research if it's all right with you "

Madam Herta: " Sure I'll send you the file later but what I have is only a summary not a full one... Her research has never really been shared with others nor published... So I don't have the full details of her research either "

Welt: " Thank you very much, Madam "

Madam Herta: " It's fine and I'm off, I have some research I need to do now... ah! I see... That's why Y/n blood was like that now that I remember about that research... Ah... This indeed seems interesting... "

Welt: " All right good luck "

And so that night

Welt Yang was kind of horrified by the content of the research File and intrigued by it at the same time

But mostly horrified and feel like he has a deja vu of just what kind of Mad scientist would do this
