Y/n Pov

Today is a nice and cold day as looks like snow will fall and on this nice cold day I am in front of a store

Y/n: " Are you ready kids! "

Nico: " Aye aye captain! "

Yui&Rei: "" Ready! ""

Emi: " Y-yes "

Jun: *Facepalm*

Y/n: " Okay then now let's raid the store and buy the decoration we want" I said and point at the store

Nico: " Go! " she went in

Yui&Rei: "" Yay! let's go Oni-Chan "" they grab my hand and drag me to the store

Emi: " w-wait for me " she went in

Jun: " Kids *sigh* " she went in calmly

And now the kids are all trying to find some decoration for the Christmas tree and the house

While I let Nico and Jun to go search alone I go with Yui, Rei, and Emi who is now choosing on which decoration and other stuff they should buy

Y/n: ( Hehe looks like they are having fun)

Alter Y/n: " Yup "

Y/n: ( Now is there anything that we miss?)

Alter Y/n: " Hmm... Let's see...Ah! We don't have our carriage and the deer yet "

Y/n: ( Aaahh I forgot Santa carriage)

Alter Y/n: " Do you think this store sell rain deer and Santa carriage "

Y/n: ( I don't think so let's just ask the cashier)

Alter Y/n: " Yeah "

Time skip brought to you by ??? stalking Y/n from the shadow

After all the kids done buying the decoration they want I go to the cashier to buy it and see the person on the cashier wearing Santa girl outfit

Cashier? : " Ara~ you done searching for something to buy "

Y/n: " Yes "

Cashier? : " Fufu you have a a really cute little sister's " she said while packing the stuff that we just buy

Y/n: " yes they are cute aren't they "

Cashier? : " Yeah and The total of you're buying will be around 345.000 Eris "

Y/n: " Ah yes.. " I then check my wallet that is not that so thick right now

Wallet-San: { Noo please don't I will lose my mean in existing if you take the money that is left! }

Y/n: " Sorry wallet-san but I need the money "

Alter Y/n: " You deed shall forever be remember Wallet-san "

Wallet-San: { No Nooooooo! } I take every last money that is left on the wallet

Y/n: " Wallet-San forgive me "

Cashier? : *Giggles*

I gave the money to the cashier woman

Y/n: " Ah sorry about that "

Cashier? : " It's fine, it's fun to look at Hehe "

Y/n: " Ahahaha... So do you maybe sell or rent a Santa carriage here or rain deer maybe "

Cashier? : " Fufufu of course n-"

*Thud*
*brak*

I hear something heavy fall from the room behind the cashier lady

Cashier? : " Ah don't mind that it just some rats it a daily thing so don't mind it " *Smile*

Y/n: " O-okay " ( O-oh that is a cute smile yet for some reason I'm scared of that smile why!? )

Alter Y/n: " ..... For some reason I'm also scared of her and I'm an Alter why!? "

I grab the stuff that has been packed in a box

Cashier? : " Thank you for buying and see you next time Y/n-Chan "

I hear her call my name, i look back and she's gone

Y/n: " Huh where did she go and how does she know my name again "

Alter Y/n: " I don't know maybe from some adventurers cause we did fight against the Dullahan "

Y/n: " Yeah " I then walk out of the store and see the others waiting in front of the store safe

Nico: " Oh that is a big box "

Y/n: " Yeah let's go home and start decorating "

Yui: " Yay I can't wait to put the decoration "

Rei: " Me too "

Nico: " Onii-Chan will santa Claus come "

Y/n: " Hehe of course he will come "

Alter Y/n: " Yeah and we will make sure of that "

And so we start going back home

Cashier lady?

Cashier? : " Ara~ Looks like Y/n has left, now what should I do with you hmm? " she said looking at the person that is tied up by ropes and his mouth taped

Original cashier (Issei) : " Mmph! "

Cashier? : " Realesed, let me think hmm... " she make a gesture like she is thinking of something before making scary face

Cashier? : " Nope you make Y/n-Chan suspicious of me, I was thinking of releasing you if you were being a good boy but you didn't so " and summon a rifle on her hand and aim it at the boy head

*Bang*

*Splat*

Cashier? : " Aww you make my clothes got blood on it, it was such a good outfit oh well....Hehehe Merry Christmas Y/n-Chan I hope you like my present Hehe "

She then go dissaper into the shadow

Y/n Pov

I was walking home as I felt my body shivering for a sec

Y/n: ( What was that why did I just shivered )

Alter Y/n: " I don't know "

We then arrived at home and put the Box down in front of the Christmas tree that haven't decorated and just recently cut down by me this morning

Y/n: " Now let's start dmthe decorating  Banzai "

Nico&Yui&Rei: "" Banzai! ""

Emi: "B-banzai "

Jun: "OK let's start decorating " *Start taking out the decoration from the box*

We then start decorating and after a while Lily-San came and helped us before someone come and shouting at the front of the hous

???: " LIILLYYY-SANN! " a male was shouting

Y/n: " Ow! my ears who is that!? "

Nico: " Ah! It's uncle Asta is he coming to visit!? "

Jun: *Facepalm* " Of course he is but his main objective will be meeting Lily-San "

Lily-san was embarrassed as her face was red before going to the front door to open it and a male come in

Uncle Asta: " Lily-San! I miss you! "

Lily: " A-asta please don't shout my name like that! "

Uncle Asta: " I don't care I shall shout your name to show you my love "

Lily: *Blush* "Kuh.. " she was embarrassed and cover her face with her hand and run inside the house

Uncle Asta: " Wait " he slump down with black cloud on top of him

While the other that I watching

Nico: " Pfft.. Hahaha Uncle Asta got rejected again "

Y/n: " That must be hurt "

Alter Y/n: " Yeah but it seems like this has happen a lot "

I then take another decoration from the box but what I got is a small red colored present box with golden tape also with a tag saying 'For Y/n-Chan'

Y/n: " What's this? "

Alter Y/n: " Who knows open it "

I open and once I see what it was my face went a total red it was a panties

And there also a paper that said 'I just recently wearing it Tehee~'

Y/n: ( Wha-what should I do with this panties )

Alter Y/n: " Hide it quick "

Y/n: " N-no we should throw it or return this to whoever gave me this "

Jun come back and see me with a bright red face as I was quickly trying to hid the panties

Jun: " What are you hiding there Onii-chan " she stare at me

Y/n: *Blush*" Ah.. Uh nothing yeah nothing uhh...Please stop staring "

But she keep staring at me before instantly goes to my back I also turn around while accidently drop the panties

Y/n: " U-uh I'm innocent " she went red and raise her hand

Jun: " O-Onii-Chan no HENTAI! "

*Slap*

---------------------------------------------------------
Rei: KO

Yui:NO

Nico: SU

Jun: Hmpf! BA
-----------------------------------------------------------

And with that I have slap mark on both of my cheeks and also spend about twenty five minutes of scolding and explaining

Jun: " Hmph fine I forgive you this time " *Pout*

Y/n: " I'm sorry okay " ( Scary)

Alter Y/n: " Ah as a wiseman once said hell had no scorn on a woman wrath "

Y/n: ( Yeah )

We then continue decorating with Asta who also come helping even thought I had an argument no challenge?

Flashback a few minutes ago

I was working putting the decoration with red slap mark still visible

Asta come in and see me

Asta: " Are you Y/n L/n "

Y/n: " Yeah so you are Asta "

Asta: " Yup that's me nice to meet you and also I want to clear something " he said as he got close to me and have serious face

Asta: " Lily-San is mine! I won't let you have her! "

Y/n: " Okay okay she is not my type so it's fine "

Asta: " Hah are you saying Lily-San is not attractive "

Y/n: " Wha-No "

Asta: " See you like her Grrr.. "

Y/n: ( What do you want me to say then)

Alter Y/n: " Just don't say anything or knock him out "

Flashback end

And now we are almost done just to put the star on top of the tree I put Rei  and Yui on my shoulder and go up the tree and let them put the star

And with that we are done

And Asta and Lily-San was heading out for a dat-walk around seeing the city that is celebrating Christmas

Y/n: " And with that Onii-Chan will go out for a bit and call Santa-San to come "

Nico: " Really! "

Y/n: " Yes! "

Yui: " Yay Rei-Chan Onii-chan said Santa-San will come "

Rei: " Yay "

Emi go toward me and said in low voice

Emi: " Please be carefull Onii-Chan "

Y/n: " Of course " I look at Jun and she just pout at me

Jun: " Hmpf "

Y/n: " Ahaha " I go out and go to where I hid the present bag and costume

Y/n: " Hehe let's go Alter "

Alter Y/n: " Yeah "

Time skip brought to you by someone stalking Y/n by the shadow when he was changing to Santa costume

No I was fully ready and on the rooftop of the orphanage

Santa Alter Y/n: " Now let's go to that fireplace "

Y/n: " Yeah also I will be gone for now and be one with the emotion this time "

Santa Alter Y/n: " Yeah "

Alter then get in to the hole but it was too small for the present bag to get in

Santa Alter Y/n: "..... I'm just gonna go in from the window "

Santa Alter Y/n: Lurk

I then get in from the open window on the kitchen and appear in front of the fireplace

Santa Alter Y/n: " Hohoho Surprise Santa-San is here"

The kids were surprised before some went and hug me

Nico: " Ooh Santa-San is here Yay! " and hug me

Yui&Rei: " Yay! " also hugged me

Emi: " U-uh Y-yay "

Nico: " Oh that's so cool  "

Santa Alter Y/n: " Yeah he is cool " *Imagination*

Santa Alter Y/n: " And with that here is you're present " I open the present bag which for some reason is more full than before like someone add some more gifts here

Once I gave the present bag to them as I thought there was more present than before

Yui: " Yay a new toy "

Rei: " Ah a big Bunny doll "

Alter Y/n: ( Eh I don't remember buying that doll )

Jun: " Hmm cooking utensils and clothes "

Emi: " O-oh I've been searching for this novel " she said as she hug the big story book

Santa Alter Y/n: "Hohoho Well that my child is a Guitar it may help you in you're future dream to become an Idol you can ask you're Onii-Chan later on how to play it "

Nico: " Oh really amazing thank you Santa-San "

Santa Alter Y/n: " Hohojo Well then now my dear I need to take my leave as there are still lot of kids to give present to "

The kids: "" Bye Santa-San! ""

And with that I go out through the front door the kids who watch me go out from the front door some have star on their eyes while Emi gave a smile and Jun gave the face that saying 'Oy Santa don't go out by the front door'

I go our and once I got back to my hiding spot I change back

Alter Y/n: " Time to go back "

I get back in and the kid went to me with a smile

Nico: " Onii-Chan! Santa-San came! and gave us present and did Santa-San gave Onii-Chan those new clothes? "

Yui: " Ooh Onii-Chan look cool with those new clothes "

Rei: " Yeah there also a present box with Onii-chan name on it "
