Daytime was soon to slowly go tonight as boredom lingered on my emotionless face while I lay on the floor in Muzan's headquarters. Nothing there was fun to do except watch Akaza beat the crap out of Douma, which was quite entertaining since he disrespected the other butterfly woman I used to love. I sighed and looked at Muzan's workplace up on the ceiling until an idea popped.

Y/n: "Blood demon art....." tentacles grow out of my back and shoot me up to his desk, then suck onto the floor without being able to fall. I didn't realize he had that much stuff, especially lab equipment. Y/n: "Well, well, well, what do we have here~? Maybe I can use his stuff if I find that little butterfly girl again..." Smirking to myself, I took a quick peek at his book and skipped many pages; I mean, who wants to read a boring book with science stuff? Well, that quickly changed my mind ever since I saw that one butterfly pillar doing her work in her office; I mean, look at her! She's too beautiful and powerful to eat her all at once! It is so elegant yet so dangerous that it makes my blood feel pleasurably aroused. I couldn't stop myself! Until I almost got caught by a water pillar, damn he's so annoying.....getting in my way every time I get near her...I want to eat him up first. But now that I have my plan, I will make her mine.

K: "Y/n, you know you're not supposed to be at his work, especially when he's gone to get more humans," Kokushibo said as he looked at me with all eyes staring above. Y/n: "Ugh, but it's boring around here! But don't worry, it's not like I'll use his stuff every day when he's not looking~" D: "Are you seriously asking for more crucial punishments from him? Unless you're into these kinds of stuff, y/n~"ignoring Douma, during the past few pages being flipped I found this one interesting liquid that looked very purple like substance called an aphrodisiac. I guess it's supposed to make a person very sexual when putting it in foods....drinks...and drugs?.. P E R F E C T~! "Y/n: "I think I found something to have fun with today!" Quickly making the potion, Akaza stares at me with a questioning look. A: "Why couldn't you just play with Susamaru?..." "I don't have time to play with a child and her balls in the streets when I'm gonna play with a butterfly in bed under the sheets~."

Y/n: "Besides, it's not like any of you demons have love interactions with anybody anyway, so I'm gonna break the rules whether he likes it or not~" M: "Whether I like it or not, what-...." I felt a very dark auroral presence behind me as I slowly turned around with a smile that I never regretted showing to Muzan. "Heeey daddy o' a long time no see huh~? Well, sorry for the invasion of your workspace, but I gotta moonwalk out of here, hehe~ I got a butterfly to capture!" Quickly disappearing, everyone knew how disappointed they were with me in this so-called "dating," especially with despised humans; like, what are they? My so-called parents?, but I wouldn't care less if they did, especially if it's a girl like what's her name?.......oh yeah-.....Shinobu~

It was already late, and she hadn't arrived at her office yet. Slowly and quietly opening the window, I sneaked inside with the love potion still in my hand and went to her desk, observing everything; wow, isn't she just a science freak... I've also noticed that she hasn't touched her food yet, so now is an excellent chance to test this out! Popping the lid out, it only took about three drops, then went straight into her syringe and poured every single substance in it in case plan A didn't work. My plan has to work either way, or she'll find and kill me without taking a single drop of my love in her mouth that I made~!

S: "Ara ara, the mission took longer than expected, but at least we finally get to eat Tomioka-san~" Oh, oh o, I heard footsteps coming yet; I don't have an excellent place to hide around here! This is total bull crap... and what the hell is the water pillar doing with her! The only place I could hide was under her desk. The footsteps slowly come but stop as I hold my breath and my heart since all the pillars know what's happening before it gets caught. Until then, there was no sound as sweat began to form on my head, but she moved very close to her desk, assuming she was getting to bite her food. S: You can leave now Tomioka, I have something important I have to do in here though it's not like you have anyone to hang out with anyway". Damn......who knew THE butterfly pillar Shinobu has such small and cute legs~ it makes me wanna take a bi- S: "Moshi mosh~ I know you're in here," she took out her sword and stabbed me underneath the table, making me whine in pain while crawling out with my tentacles being showed. "Oh wow, you're powerful with such a beautiful form~! But do you think you can handle yourself with the bite you took at your food~?". S: "What nonsense are you-" she stopped talking. Her whole body shook slightly, but she still gripped her sword. Y/n: "Oh my, so it does work! Interesting, maybe I should have used this a long time ago with your sister but mostly with you~! Maybe if Douma would have known his place, then maybe I could have two....".
