~~~ Vanessa's POV ~~~

I was in Inenna's lab, helping her make a mental switch thing or something like that, all I know is that said something like our cousin then said, "If one person sits here and the other there, we press a button that switches them," at least I think that's what she said. "And... done!" Inenna yelled as I looked at it, it looked like it was from an old show. "Alright, but... I think it was only meant to be two chairs, not three." "Eh?! I wasn't paying attention!" she yelled at herself as Sebastian, Kyoya, and Levi came in with some food. They've been our friends and roommates along with our other sister who is away for work and our beautiful cousin who has a crush on all three of them, (Y/n) (L/n), and they've been our lifesaver whenever it comes to working on something. "Young ladies, you should eat something, you don't want to starve yourselves," Sebastian said as he placed the food down on the table that's meant for food since there is another one that's full of junk.

"Tch, damn brats. You've been in this room all day, it's already 4:07 PM," Levi said as he sat down on a chair that's hooked up to the switch thingy. Inenna looked at each other then smirked before saying, "Not our fault that we like working on random stuff." "You both have been making so much noise that the neighbors came over, you also used a lot of power to make whatever you were making," Kyoya spoke before seating. "Hey, you try changing a battery that's meant to last about three years. Sebastian, can you sit down?" I asked Sebastian as he smiled and said, "Of course." he sat down next to Kyoya and Levi. "So what did you idiots make this time?" Asked Mr. Shorty McHiccops AKA Levi. "What we made is going to BLOW YOUR MIND... or at least, switch it!" "WHAT?!" all three yelled after I said, then Inenna pressed the button making them tense up before passing out.

About an hour later, they woke up. "Ugh... my head." I head Kyoya speak as Levi rubbed his head. "You damn shitty brats are going to be cleaning the house for the next week," Levi spoke next as Sebastian held his head. "Now don't be like that Levi, they just wanted to test something." Kyoya looked up making me and Inenna scream out of joy. "SEBASTIAN IS IN KYOYA'S BODY!!!" "WHY IS HE IN MY BODY?!" Kyoya asked as Levi got up. "KYOYA'S IN LEVI'S!!!" Inenna yelled before I spoke, "Which means... shorty isn't shorty anymore... HE'S FUCKING TALL!" Sebastian AKA Levi got up and looked down at us making us smile. "You better fix this or I'll kill you." "Levi, keep it together, I'm sure they'll fix this." "Uh... about that. We still need to work on it," Inenna said as Levi grabbed us and pinned us to the wall. "Fix it now or I'll shove my boot in your shitty ass, causing you having to shit it out," he said as I laughed, just then we heard a loud slam and a soft, melodic voice that can put kindness into those who seem rude and chaotic. "I'm home from work!" the boys started to freak out for they also have a thing for the beautiful (Y/n).

"Okay, mission time! Levi, act like Sebastian and act like a butler, Sebastian, act like Kyoya and go to work, Kyoya, act like Levi and go to work. Got it?!" I yelled in my boss voice. Levi put me down and growled, "Tch." "Of course, I'll keep Kyoya up to date on school and have him work on it as well." "I got it, but I think it'll be easy being a shorty." "WHAT WAS THAT?!" I forgot to tell you guys this, but Kyoya and Levi work side by side as CEOs. Sure, Kyoya's dream was to work as a doctor, but he wanted to annoy Levi for some reason. "Behave!" Inenna yelled in her boss voice which demonic. "Inenna, control your demon," Sebastian warned as Inenna growled. "Alright, alright, Levi, you need to keep track of everything and you need to make sure you control Sebastian's demon AKA your anger along with Inenna, Sebastian, you have to annoy Kyoya, Kyoya you have to act rude and disconnect your feelings so people think you're Levi. GOT IT?!" I asked as they nodded their heads as Levi set us down.

Just then (Y/n) came down and smiled before saying, "Found you guys, what's going on down here?" "Just talking, my lady," Levi spoke, getting the perfect Sebastian voice, but a bit deep. "Okay, Kyoya, Levi we still on for the trip to the fair tomorrow since it's your off day?" Sebastian and Kyoya glared at each other before replying, "Yes, we're still on for that." they didn't get their voice right, but hey, they tried and luckily, she didn't notice. "Tch, damn bastards..." Levi muttered making (Y/n) turn around and asked, "Did you say something Bassy?"

~~~ Levi's POV ~~~

Dammit, I may be fucking tall, but I feel like I want to just eat something... how does that damn demon maintain himself? I looked deep into her eyes, I can see her soul... her beautiful, delicious (f/c) soul. She acts innocent and pure, but I can see something more... more... sinnful.

~~~ Vanessa's POV ~~~

"Nothing, I said nothing," Levi spoke before smiling, although his smile was a bit off. Sebastian went to Levi and fixed it by moving his lips a bit. "Much better. I thought after doing that smile for over ten years of living together and so many years before you'd remember your own smile," he told me as Levi's smile dropped. "Alright! Everyone out! Me and Vanessa have to work on the Switch-a-Roonie," Inenna spoke as (Y/n) tilted her head to the side and asked, "Switch-a-Roonie? Why that name?" "NO QUESTIONS, MY CHILD!!!" I yelled as she giggled. "Ah, which reminds me, Levi, aren't you and Hanji suppose to be at Erwin's planning a business trip?" Kyoya cleared his throat, he was about to say something, but Sebastian interrupted him by saying, "He already went. They picked out a nice place... to s--... to Hanji's eyes." "A love hotel?" she joked before laughing making the others didn't laugh, other than Inenna holding in her laugh. "No... it's a hotel that's in Hawaii... it's also near the beach."

"AWESOME!!! I'M SO GLAD YOU INVITED ME TO GO WITH YOU ON THAT TRIP, LEVI!" once she said that, Sebastian and Kyoya and said, "We'll be right back, we need to talk about something in private." they left without another word. "Okay, spill the beans, what did you do to them?" (Y/n) asked as I sighed before replying, "We made the Switch-a-Roonie, they sat down after bringing in food for us, we pressed this button and then they switched bodies. Although we still need to get it fixed to where we can get them back into their own bodies."

"So... who's who?" "Levi is Sebastian, Sebastian is Kyoya, and Kyoya is Levi." "Oh boy... with Levi having a short temper, I think we should fear for the worse. Kyoya hates Levi, so I think something bad may happen, and Sebastian has to annoy Kyoya... I LIKE IT!"

"HUH?!"
