So since MC from my roommates from another universe is a different version of the MC from the house next door can we know more about that version of MC's family?

I am happy dancing reading this ask. You have no idea how much I wanna talk about this specific subject! The characters mentioned belong to @battlemaiden13 & if you haven't read her amazing story The House Next Door, please go do so.

The Parents:

Hank: MC's late father

Mother: MC's mother (she has no name in HND and I will not name her, so she will remained unnamed), important figure in their home country, her fate since timelines merged is unknown

The Siblings:

Asha: MC's oldest brother, worked in politics, fate unknown

Ashely: Asha's twin sister & MC's only sister (Ashely is my OC, since some of the skeletons from the hotel mentioned in some timelines MC had a sister, I thought this might be a fun addition), volunteered at schools, hospitals, homeless shelters and orphanages & often put functions together to raise money or donation drives for those less fortunate, fate unknown

Nathan: MC's older brother (3rd oldest sibling & 2nd oldest brother), worked as a scientist, developed magical weapons and gadgets with Damian and Michael, fate unknown

Damian: MC's older brother (4th oldest sibling & 3rd oldest brother), formerly in charge of a special task force in their home country's military, former weapons expert, fate unknown

My Roommates From Another Universe - Chapter 6:

A couple of days had passed with your new house guests and things were… oddly comfortable. Saffron and Romance would playfully flirt with you and sometimes boldly ask to sleep with you. That flattered you and boosted your ego to no end. The brothers were very attractive and put together, so for them to find you attractive enough to want to sleep with? Yeah, you felt great.

You, of course, turned their offer down every time. It wasn’t often you had sex. It just wasn’t your thing. Every once and while you would indulge but that was under very specific circumstances. One of those things being that you had to know the person. 

You had just met these two. Maybe once you got to know them better you’d see if they were still interested. Until then, if you ever got the itch, you’d see if any of your friends would be interested in helping you.

That’s a thought for another day, though. Right now, you had other things on your mind. You were sitting in comfortable silence with the four skeletons currently in your house while you were working on the details for your future projects. You were laying on the living room floor with Fresh next to you, only he was laying the opposite direction with his next next to yours.

Paint was sitting at the window bench while sketching, Romance was stretched out on the couch while filing… the tips of his phalanges? Okay, that was a new one. But to each their own. Saffron was in the arm chair painting his- okay why were they acting like they had nails? Why not just get press ons at that point?

Whatever. Not your business. It wasn’t your body. Besides, you had more important thoughts nagging at you.

“So, are Saffron and Romance your actual names like Fresh and Paint? Or are they nicknames?” The sounds of Paint’s pencil and Romance’s nail file stopped making it truly silent.

It was quiet for a moment before Romance spoke up. “NO, ACTUALLY. THEY ARE MORE LIKE CODE NAMES THAT OUR NEW BOSS HAS GIVEN US.”

What a coincidence. One of them shared a codename with your dear older sister. There was a small spark of hope in your chest, but you pushed it aside. You will not get your hopes up that one of your brothers ended up here with you. Turning to Saffron, you grinned, wondering what kind of reaction you’d get out of him with your question.

“You do know that your name is an aphrodisiac, right?”

His reaction was not what you had expected but was no less amusing. Saffron had sat up straight in his chair so quickly that he almost toppled his bottle of nail polish. His lavender eye lights shifted to hearts and sparked with excitement. 

“yes. how do you know that, sunflower?”

You shrugged before looking up at the ceiling. “My older sister loved those flowers. Loved the color, the smell, all the different things they could be used to make… she often had them made into perfumes and wore them either in her hair or tucked into her dress. She’d talk your ear off about them if you let her.”

You felt four pairs of eyes on you as you spoke. Which was fair since you never really talked about your family. It wasn’t that you didn’t want to. It just never came up in conversation.

“She loved them so much that we started to call her saffron. Honestly, it suited her. It was one of her many nicknames.”

Not to mention her codename for when she did work for your brother’s special team in the military.

“DID YOU HAVE ANY PLANT RELATED NICKNAMES? OTHER THAN THE ONE MY BROTHER HAS GRANTED YOU?” Romance asked with a teasing tone.

“Sure did. I use it as my stage name and part of it as my fake name.”

“oh, really? what is it?”

Sitting up, you smiled over at the two brothers. “Belladonna.”

Not me. Needing a spreadsheet for my fanfic

[undertales-across-the-multiverse]

My Roommates From Another Universe - Chapter 7:

(Originally posted on AO3 - September 28th, 2025)

Belladonna. That was the name that your brother Damian had gifted you when you joined his special military team. The world you had been born into was run by a king. However, he was more like a dictator. Your family had long served the royal bloodline and so were in high standing. 

However, the people of the country did not like you or your family. They would never say it to your faces but you knew… and you hated it. You never wanted to be a part of that mess. You were forced into it.

Your father had tried to keep you out of it for as long as possible. Until he had gone missing and presumed dead. After that, you began your training at the age of six. Most of it was useful and relevant for the world you lived in. So, in some way, you were grateful.

Your mother taught you how to fight with swords of all types. You were pretty decent at it and after years of training, you were a master. Asha, also known as Oleander, was a political figure in the country. Ashely, also known as Saffron, was a well known and well liked philanthropist.

She was the only one in your family that the common people liked. Nathan, also known as Foxglove, was a scientist. He worked with some of your other brothers to make magic infused technology and weapons. Damian, also known as Hemlock, was the most hated in the family as he was the leader of the secret military team.

Michael, also known as Larkspur, was the head tactician for the whole military. Wars were like one giant game for him. Then, there was you. You were nothing more than a political piece. A bargaining chip. That, however, was all a cover. They were the roles you played in front of the public.

You and your siblings were elite assassins. Asha and Ashely were masters with all types of poison, medicine, and knowledge of the human body. Nathan was a master of physiological torture. Damian was all about brute force and weapons. Michael was their go to guy for any and all undercover missions.

And you? Well, you were a jack of all trades thanks to your older siblings. You often worked with Ashely or Damian during missions. During the day, you spent ninety percent of your time either with your mother or Asha.

During your time there, you wished your life had been different. Now, you just wish you had your family.

It was weird not having Saffron and Romance here. However, it was great to have the dance crew back home. It was too quiet without the six of them here. You all caught up over a homemade dinner where you had made all their favorites and they told you all about the competition. They had unsurprisingly won.

That night, the boys all fought over who would sleep with you. Even Mashup and Samba. They must have really missed you if those two were vying for a spot in your bed. Fortunately, you had a great idea. A camp out in the living room.

That seemed to calm everyone down. Over the next couple of days, you got back into the groove of your work routine. Get up early, go for a jog with Tango, Mashup, and Samba, have breakfast, and then spend the rest of the day practicing with Dance. After that, you’d come home, shower, have dinner with all your boys, and crash in bed.

It was during one of your breaks for lunch that you and Dance had gotten great news. Both humans and Monsters came in to audition for your upcoming projects! Everyone who auditioned were amazing. You’d definitely have a place for all of them. 

One of them in particular caught your attention. Butterfly, a Muffet variant, had a couple of different dance styles that all had an air of seduction to them that was absolutely mesmerizing. You wanted to see how she would look dancing your main dance style, ballet, and offered to teach her.

She had agreed rather enthusiastically. This girl was someone you wanted dancing with you in your Step-Up tribute video. When you mentioned this to Dance, his eyelights seemed to shine brighter and he suggested inviting one of his dance buddies named Grind.

He’d be one of the dancers on Dance’s side. Things were finally starting to fall into place. Now, if only you could find a place to film your music videos for Halloween.
