3rd pov

As y/n show Ink and Error around, they was starting to wonder how y/n was a sans. Since he has a job while other sanses don't... Expect Sci, who is a scientist.

Y/n: Now, here are your rooms. First ink room.

Y/n open the door to ink room.

Y/n: Sorry if it too small, or it not to your liking.

Both Error and Ink were in awe.

Ink: I love it! It's so cozy!

Y/n: Yeah, I like cozy things. Isn't that right Opal?

Opal nodded and rubbed her head against y/n face.

Y/n: Why don't you get comfortable, while I show Error here his room.

Ink nodded and went inside the room. Y/n close the door.

Y/n: Come along now.

Y/n started to walk away as Error followed. After sometime, Error spoke.

Error: HeY, uMmM...

Y/n: Yes?

Error: CaN yOu MaKe Me A nEw OuTfIt? SiNcE tHe StAr SaNs AnD uS aKa ThE bAd SaNs AiN't EnEmIeS aNyMoRe.

Y/n: Of course! Any colors you want? Cozy? Loose-fitting? Fancy?

Error: Cozy please. And anything in blue, red, yellow, And Orange please.

Y/n nodded and made a mental note. After a while, the two reach error new room.

Y/n: Knowing you, you probably want to be away from ink. Plus you seem to be the type of person who wants privacy, so this room right here is away from others and If you don't want to leave your room, I understand. Katelyn didn't leave her room after her pet turtle went into hibernation. But she understands it apart of Hank species.

Y/n open the door as error look around.

Y/n: This room is cozy, comfortable, and have a nice atmosphere to read or creat. Just like Ink room.

Error nodded as he walked inside. Y/n close the door and look at Opal.

Y/n: Hope they get comfortable here.

Y/n walk away as Opal jump off of y/n shoulder.

Opal meow, telling y/n that they'll be fine.

Y/n: Your right, Opal. Now let's get you some food. I have to make dinner anyways since battling those mages took almost all day.

Opal ran down the stairs and into the kitchen. Y/n follow behind Opal and open the cabinet door. Y/n grab some Fancy Feast cat food. Y/n open the can of Fancy Feast cat food and poor it into Opal bowl.

Y/n: Here you go, Opal. Some Fancy Feast cat food. And it is your favorite! Salmon Feast with gravy.

Opal meow happily and started to eat. Y/n threw away the empty cat food can and started to cook some ramen.

Y/n: Do you want me to sing, Opal?

Opal stopped eating and meow, telling y/n to sing. Opal then went back to eating

Y/n: Wonderful! Now which song to sing.... Oh! I know! How about Everything at Once by Lenka? What do you think, Opal?

Opal stopped eating again and meow, telling y/n to sing it.

Y/n: Glad to have you here Opal.

Opal meow happily and go back to eating.

Ink pov

After getting settled in, I walk out of my room to see the door change. Instead of the plain brown door, it was pastel rainbow colors with my name craved into the door.

Me: Whoa....

I saw error walking over.

Error: YoU sAw It As WeLl?

Me: Yeah.

Error: My DoOr WaS mOsTlY dArK bLuE fAdEd InTo BlAcK wItH mY nAmE cRaVeD iNtO iT.

Me: Let ask y/n about it.

Error nodded and we went to find y/n, after a few minutes we couldn't find her up stairs but we did hear talking from the kitchen. Both me and Error walk over to the dining room.

We sat down at the table as look twords the kitchen to see y/n cooking something while Opal was eating cat food.

Y/n: Do you want me to sing, Opal?

Opal stopped eating and meow, telling y/n to sing. Opal then went back to eating.

Y/n: Wonderful! Now which song to sing.... Oh! I know! How about Everything at Once by Lenka? What do you think, Opal?

Opal stopped eating again and meow, telling y/n to sing it.

Y/n: Glad to have you here Opal.

Opal meow happily and go back to eating. Both me and Error look at each other having the same thoughts as "Pretty sure she can understand Opal."

[Y/n]
As sly as a fox, as strong as an ox
As fast as a hare, as brave as a bear
As free as a bird, as neat as a word
As quiet as a mouse, as big as a house
All
I wanna be
All
I wanna be
Oh-oh-oh, all
I wanna be
Is everything
As mean as a wolf, as sharp as a tooth
As deep as a bite, as dark as the night
As sweet as a song, as right as a wrong
As long as a road, as ugly as a toad
As pretty as a picture hanging from a fixture
Strong like a family, strong as I wanna be
Bright as day, as light as play
As hard as nails, as grand as a whale
All
I wanna be
Oh-oh-oh, all
I wanna be
Oh-oh-oh, all
I wanna be
Is everything
Everything at once
Everything at once
Oh-oh-oh, everything at once
As warm as the sun, as silly as fun
As cool as a tree, as scary as the sea
As hot as fire, cold as ice
Sweet as sugar and everything nice
As old as time, as straight as a line
As royal as a queen, as buzzed as a bee
As stealth as a tiger, smooth as a glider
Pure as a melody, pure as I wanna be
All
I wanna be
Oh-oh-oh, all
I wanna be
Oh-oh-oh, all
I wanna be
Is everything
Everything at once

After y/n got done singing, he look over to us and his eyes widen. Mine and Error jaw drop a bit, since we didn't know y/n can sing.

Y/n: How....much did you guys hear?

Error: AlL oF iT, y/N.

Me: You have such a lovely voice.

For some reason I felt my face getting hot. I look over to error to see he got some yellow blush on him.

Y/n: Well, your not the first to say it. My younger sister can sing beautifully while Carlos can also sing.

Error: So, If YoU'rE a SaNs.... WhY dIdN't YoU mAkE pUnS wHeN wE gOt HeRe?

Y/n: Here a pun. How can you spot a nosy pepper?

Me: Don't know.

Y/n: It gets Jalapeño business!

After a few minutes of silence, both Ink and Error started to laugh along with Y/n.

Y/n: It just, I'm very busy and don't have time for puns. Plus, I think dinner is ready.

Y/n put the food in three bowls and then handed both me and error one bowl.

Error: WhAt Is ThIs?

Y/n: Ramen. One of Carlos favorites dishes. Carlos have five dishes he like. The second being: Sashimi, The third being: Udon, The fourth being: Pasta, and The fifth being: Rice especially broccoli and cheese rice.

Me: So, what does your family do?

Y/n grab some sticks from the drawer.

Y/n: My dad is a scientist, my mom is a School Nurse, My older sister aka Mallory is a Doctor, my older brother aka Markus is a Librarian, my younger brother aka Callum is a chef, while my youngest sister is still in highschool.

Error: So CaLlUm Is ThE pApYrUs Of ThIs Au?

Y/n nodded and handed me and error two sticks.

Y/n: These are call chopsticks, I use them when eating ramen, sushi, sashimi, and udon.

Me: We never use chopsticks.

Y/n: It's easy.

Y/n pick up some noodles and ate them. So we copy y/n and started to eat.

Error: ThIs Is GoOd.

I nodded.

Y/n: Thanks.

Me: So-

Y/n: If you wondering what my soul trait is. I can't. Me and my friends need to get to know you first then we can show you. That's the rules.

Error: WhY iS tHaT a RuLe?

Y/n: Look, I'm going to be straight with you.... Me and my friends.... We're special cases. You see people in the world can be born with one trait or a dual-traited. I do have a monster soul but it only shows around the outer ring.

Me: How can you have a monster soul when-

Y/n: My father side of the family was all monster until my x5 times great grandmother married human. Then so on and so on until my dad married my mother.

Error: So WhAt YoU'rE sAyInG iS tHaT-

Me: If you marry a monster, your child will be half human and half monster?

Y/n: Yep. When my x5 great grandmother married a human, my four time great grandfather became the first human-monster hybrid. Then when he married my x4 great grandmother, their daughter aka my x3 great grandmother married my x3 great grandfather. The monster bloodline was lost in the family but it was still there. Monsters use their magic to create a child while humans reproduce normally. I'm Demisexual and Homosexual.

Error: BuT mAlEs CaN't GeT pTeGnAnT, sO hOw CaN yOu HaVe A cHiLd?

Y/n: Male couple or lesbians couples can either adopt a child or use magic, but that for monster couples. Human couples, in order to create a child through magic, they need help from a powerful mage. There is a nice old lady who is a powerful mage and has lived for hundreds of years. She helps humans gay or lesbian couples out. They can still adopt kids and still love them like their own. She can even help change the blood type and DNA of the adopted children so that way they can be the biological child.

Both me and Error were in shock.

Y/n: But enough about the whole thing. So, how do you two do for fun?

As we were telling y/n about ourselves while eating. After we got done eating we heard three thuds. Coming from upstairs.

Y/n: Must be more of you. Here, you go get them and I'll clean the bowls.

Y/n grab our bowls and put them in the sink. As both me and Error walk up the stairs to hear three familiar voices coming from y/n sewing room.

Blue: Wowie! This room look amazing!

Classic: Yeah... Wonder who designed these.

Red: You think whoever did will make me a new outfit?

I open the door as error walks through.

Error: SuP.

Blue: Error!

Blue hug error, error glitch out a bit and moved blue away from him. Seems like he ain't over his fear yet.

Red: Where are we, Ink?

Me: We're in Harmonytale.

Classic: Harmonytale?

Error: YeP. HuMaNs And MoNsTeR lIvE iN hArMoNy ToGeThEr.

Me: To maintain the balance, mages and monsters made six crystals to keep the balance between humans and monsters.

Error: Y/n MaDe ThEsE oUtFiTs, SiNcE hE iS a FaShIoN dEsIgNeR. eVeN tHoUgH hE iS a SaNs FoR tHiS aU.

Red: Huh, a sans au have a job. And not just being a scientist like Sci.

Blue: IS HE THE ONE WHO MADE THE DRESSES?

Me: Yes, also blue inside voice.

Blue: Sorry.

Error: It'S fInE, bLuE.

Classic: So where is the....owner of this house?

Y/n: Right here.

Y/n walk right behind us with a smile. His cat being on his head.

Y/n: Hi, I'm Y/n. My full name is Y/n L/n. And this is my pet cat: Opal.

Opal meow as her tail flick.

Y/n: She a little sassy when she meet new people. Isn't that right, Opal?

Opal meow again.

Blue: Opal is so beautiful.

Opal has a smug smile.

Y/n: Seems like you stroke her ego abit. Anyways, what your names?

Me: Oh! There names are: Classic, Red, and Blue.

Y/n: Okay, anyways. Ink, Error. Show them to their new rooms. I'll be downstairs watching some anime. You can join me once you find your rooms.

Y/n walks away with Opal still on his head.

Blue: Come on! I want a room so I can watch anime!

Error: OkAy, OkAy. FoLlOw Us.

We all walked out of the sewing room and went to show the three of them their rooms.
