Welcome to yet another story for yet another fandom. This time I shall be giving you a story for Daily Life with the Monster Girls or Monster Musume No Iru Nichijou.

Before we begin, I want to get this out of the way now. I just wanted to write something I can relax my brain to, while I plot out my other stories...and this will most likely be a series of short stories with a few arcs in between...like the manga. Also, expect some slice-of-life wackiness with more than a few...fanservice scenes.

With that out of the way, on with the show

Chapter 1: W.M.D - Weapon of Mass Destruction, Uno-chan

...

...

Kurusu Kimihito was stressed.

Well, in all honesty, that was an understatement. Being the host of a grand total of seven liminals, tends to be quite stressful, especially since one household or host family is only supposed to host one liminal or extraspecies exchange student and on some occasions there were two, but that was only in case the exchange students were twins, who didn't want to be separated from each other. That being said, 7 liminals in one household was a new record. Not that there were any rules against that, since Ms. Smith clearly dumps any Liminal she can find or can't find a host family for to Kurusu.

Alas, I digress.

The point is that Kurusu was stressed, but it wasn't because of the girls...specifically. If anything he cared about his housemates and friends to the point where he considered them as his family. No, he was stressed because his entire food budget has gotten a little off track...

Nope, that was an understatement. It would be more accurate to say that his food budget flew off the rails and went straight into space.

That is to say, that Kurusu Kimihito had no clue as to how he can feed his new friends, now that he had little to no money for buying food. Lala coming to live with them was actually the straw that broke the captain's back in that regard...in a manner of speaking, of course.

Kimihito Kurusu fixed a calculating stare at the notebook infront of him, as if the numbers written on it would magically show that their food budget was okay and not in the red, if he stared at it long enough. No such luck though.

That's when a light bulb lit up in his head.

"That's right I still have some leftover ingredients in the fridge" Kurusu mused to himself. "If I use those just right..."

He stood up and quickly headed for the kitchen and opened the fridge with hope building up inside him. He could save their budget, if he could just use those ingredients to make din-

It was empty.

Kurusu stared dumbly at the fridge, which was now devoid of any sort of food. He continue to stare at the sight disbelievingly, before he started opening and closing the door repeatedly, as if he was hallucinating.

"I could've sworn I left them in here when I made lunch..." He said to himself bemusedly. Had he made a mistake and have run out of ingredients afterall? No, of course not, he distinctly remembered putting the leftover ingredients in the fridge, when he made lunch.

That's when he caught sight of a distinct red tail from his peripheral vision. In an instant, his face paled at the implications of the situation. It's not like he had any problems with Miia...at least not ones that would elicit this kind of response from him...it's just that the implications were downright horrifying.

He gulped nervously and prayed to every god, saint and kami he knew of that Miia hadn't just used his last hope for saving their food budget for another one of her 'practice sessions'.

"Miia, do you know where the stuff in the fridge went?" He asked, already dreading the answer that he was going to see. He turned around to face the direction of the red tail.

His heart plummeted somewhere near his stomach at the sight of Lala's soul leaking out of her mouth with a very disturbed expression om her face, Lala's neck cross-section billowing out smoke like a chimney, and Miia holding a tray with two bowls, which were quite obviously filled with her latest...concoction.

"You didn't taste it again, didn't you?" Said a disturbed Rachnera as she eyed Lala's severed head as her soul leaked out of her mouth.

"I tasted it!" protested Miia offendedly.

You know, Miia's food could easily become one of the Lamia species' deadliest poison...or at the very least a very effective non-lethal(?) version of knockout drops. Her mother would be so proud of her!

At any rate, Kurusu was too busy weeping and mourning over the pots and pans filled with Miia's latest poiso- er, I mean, results to actually hear the bickering coming from the two liminals.

"What's wrong, darling?"

He spared one last glance at the pot and pans filled with rui-...food(?)...and heaved a sigh.

Either way you look at it, one thing's for certain.

Kurusu Kimihito had to go food shopping.

Again.

"Well, it looks we'll have to go sho-" Kurusu's declaration merely fell on deaf ears as the sound of his doorbell chimed right in his ears.

He already had a vague idea as to who this was by the time he reached the door. Still, he hoped and prayed that he was wrong this one time because if he was right...he dreaded to imagine how he'll be able to keep his new family fed.

'No use delaying the inevitable.' He thought to himself as he opened the door and sure enough, the local cultural exchange coordinator was standing in front of the door way with the ever-present smirk and sunglasses on her face.

Yup, this was Miss Smith and she wasn't alone.

Standing beside her, while also almost completely hiding behind the cultural exchange woman was a doll-like young boy with girlishly short azure hair and eyes of the same color with black sclera. He was also wearing a loose-fitting royal blue fur coat with white fur on the hem of the sleeves, as well as, the outer edges and collar, which extended all the way past his knees; it was clearly too big for him. He also wore black pants, a white scarf and black boots. From the overall looks of the boy, he was roughly twelve years old, but then again he was clearly a liminal, so for all he knew this boy could be roughly the same age as him or maybe 5 times older than him.

Afterall, this seemed to be mostly the case with Papi and Lilith.

For a moment, Kurusu felt relieved that Ms. Smith didn't come with MON for another feast...that is until he realized what this situation entailed.

The gist of the matter is that Kurusu had yet ANOTHER liminal guest in his house. Not that he was complaining, he just wished that he had a way to feed all of his guests without compromising on anything. He was cool and kind like that.

Don't let the disbelieving expression and gaping mouth fool you, he really doesn't mind having all these houseguests. Really.

The boy tugged at Miss Smith's skirt lightly, before hiding behind her even more, while looking neutral.

"I don't think he's happy to see me" recited the boy in a mellow and slightly pubescent sounding tone that sounded a little high, but distinctly male.

Ms. Smith merely gave an amused chuckle.

"Don't be silly, Uno-chan. Mr. Darling here is the host of 7 liminals, so what's one more addition, right?"

Yup, Ms. Smith was dumping another liminal on him and just when he's completely stressed out with trying to balance their food budget too. Also one liminal would make a huge difference, since some liminals have certain special needs and catering to those needs could very well be time-consuming.

Poor guy, but then again, he keeps bringing this onto himself, since he's clearly unable to say no to any liminal who wants to stay with him...or any liminal, period. Does he have a white night complex or something?

Then again he is a harem protagonist, so this should be expected...

The boy turned his azure gaze towards him for a quick second, before turning back to Miss Smith.

"He is clearly in distress and disbelief. His increased heartrate, pulse and brain activity clearly show anxiety and stress. I don't want to be a burden simply because of my unique...condition, so perhaps we should look for a different host family" recited Uno, while looking at Smith with a poker face, whivh still looked doll-like.

Of course, being the kind and masochistic...or kinda masochistic person that he is, Kurusu simply denied such a claim.

"N-no, it's fine, it's fine, I was just a little caught off guard that's all" Kurusu claimed, but the boy still looked a tad bit skeptical.

"See, Mr. Darling here doesn't mind one bit, Uno-chan" Ms. Smith encouragingly.

Not that Ms. Smith would take no for an answer even if he DID mind, which is highly unlikely given his character and personality, along with, Ms Smith's history of dumping off her workloads at the young man.

Uno looked at Kurusu who simply gave him a reassuring smile in return, before the 12 year old simply nodded to Ms. Smith and proceeded to step out from behind the woman to bow directly to his new host.

"It's a pleasure to meet you, Kimihito Kurusu, my name is Uno and I'll be you new house guest" recited Uno innocently with a small smile, before he raised his arm and extended his hand.

His Robotic hand.

To his credit, Kurusu didn't even miss a beat as he shook the boy's hand with a kind smile on his face. You'd think that this wasn't anything unusual or was perfectly normal for him with how nonchalant, casual, and blasé he was about seeing an azure and silver-colored, armored robot hand.

Then again, that's just part of his personality; the apparent ability to not bat an eye at the presence of anything that would usually make normal people flinch in fear and slowly back away.

He was either incredibly naivé or just plain kind-hearted.

"It's nice to meet you, Uno" Kurusu replied warmly, which prompted the young boy in question to furrow his brows in question at the nonchalant and blasé response.

Clearly, he wasn't expecting a response like this. Fainting at the sight of his robotic arm, Yes. Screaming and runnning for the hills, sure. Slamming the door on his face, why not?

But this? He hadn't been expecting anything like this.

From what he was able to gather, humans rarely reacted this warmly to something or someone that is overtly different from them in more ways than one. So he had prepared himself for the worst ahead of time by deducing the most likely reactions from his new host...which was something he now needed apparently...

"You are reacting surprisingly well at the sight of my robot arm" Recited Uno monotonously, albeit bemusedly, while looking at Kurusu with a cute bemused expression that belonged to someone from a shounen manga.

Kurusu simply chuckled dismissively.

"It's not all that different, I mean you maybe a liminal, but you're still a boy afterall"

Uno stared at the man's face, analyzing every inch of his facial expression and looking for the slightest clue or leak that this was all a facadé and that Kurusu was simply putting up a brave front.

He found none.

This fact only served to confuse Uno even more.

Then again, Kurusu is still oblivious to what I really am. Uno mused to himself. As soon as he finds out, I'd wager that he'll go running to the hills, before bothering to listen anymore. It's human instinct afterall; self-preservation, that is.

"Oh stop being so over-analytical, Uno-chan. Darling-kun isn't like most humans" Smith said with a dismissive smile at the boy's efforts.

No shit. Most humans wouldn't have been able to survive the things this guy has went through. Seriously, I don't have enough fingers to count all the near-death experiences this guy's had. What, is he immortal or something?

"That seems to be the case" agreed Uno monotonously, albeit innocently without taking his eyes off the peculiar man. "Not only does he not show any repulsion or fear to liminals, but he also seems to have survived a number of near-death experiences"

See? Even Uno thinks so.

Kurusu simply waved off the praise(?) and laughed nervously.

"It's nothing special" he waved it off.

Uno begged to differ.

"Well, why don't we get you settled in then, Uno-chan" Smith suggested to which to boy nodded.

Uno simply nodded before he walked over to the side of the doorframe. Evidently, fetching something out of sight, which made Kurusu furrow his eyebrows in question.

What Uno pulled out was a very wide very tall cylindrical...machine? Well it was very thick, since Uno had to wrap both his arms around it to support it and was roughly twice as tall as the boy holding it. It had a distinct technological and mechnical theme to it, which led Kursu to believe that he wouldn't be able to offer Uno much help.

He wasn't an expert with tech or machines.

The totem seems to be divided into 10 equal levels, which rotated in alternate directions and each level having 20 separate slots or compartments. The metal frame of the totem was mostly silver, while there were some parts that glowed azure.

It looked heavy, that's for sure.

Kurusu jaw dropped to the ground, when he saw the boy heft the totem horizontally onto his shoulder effortlessly and started walking into the house, while supporting the machine with both arms.

Kurusu might've believed that the thing weighed no more than a piece of paper, if it weren't for the fact that the ground kept shaking with every step he took.

Smith walked in and without missing a beat started fixing herself a cup of coffee.

Kurusu simply followed suit and closed the door, albeit looking slightly perturbed.

...

"Hm? Ms. Smith? What're you doing here?" Kurusu heard Miia ask as he reached the living room where Uno sat primly near the edge of the sofa and the mechanical totem was placed by his side.

"Hm? Oh, I just dropped by to bring your new housemate"

"ANOTHER ONE?!"

Kurusu already figured that Miia would react in such a way. Even though she didn't know the gender of their new guest. Plus, so far, all new additions to their little family have been all girls so the words 'new housemate' practically meant 'new rival' to Miia.

Uno looked at Kurusu with a raised eyebrow, while the latter simply waved a hand dismissively. He really didn't want to explain the intricacies and complications of his relationship with the girls to a 12 year old boy, of all people. Also, Uno looked really innocent and cute that he didn't have the heart to corrupt his young mind with complicated adult stuff.

Though he had an inkling that he won't be able to completely shield the little boy.

"A new guest?" Rachnee's voice sounded curious as she inquired.

"That's right and it's a special case this time" assured Ms. Smith.

Kurusu's eyebrows furrowed at that. Sure, he hasn't met a robotic species of liminals before, but...he wouldn't say that it was a special case.

As if on cue, Centorea, Suu, Papi, Mero, and Lala (don't forget about her) walked into the living room. Talk about plot convenience, huh? Once they entered, they stopped in their tracks as soon as they spotted innocent and curious gaze of the azure-eyed, black-sclera'd newcomer.

"At any rate, I can guarantee that you won't have to worry about a new rival this time, Miia" was what Smith said before she stepped into the room as well.

"Grrr, it better be, 6 rivals are already too many!" Whined Miia before she and Rachnee stepped into the living room as well, but they, too, stopped in their tracks when they noticed the young boy.

Uno simply looked at each of the girls slowly with an innocent and curious gaze before he turned his attention to Kurusu.

Without changing his expression, he nodded understandingly, while mouthing "Ohhhhh", before he gave him a small sympathetic smile.

Okay, so maybe, Uno wasn't as innocent as Kurusu had first assumed.

"Well, that's convenient" declared Ms. Smith with her trademark smirk, before taking a sip of coffee. "Since you're all here, I don't have to repeat anything"

Classic Smith.

Ms. Smith simply walked over to the little boy and sat down beside him on the couch. Everybody followed suit and started making themselves comfortable.

"Anyways, meet your new housemate everyone, this is Uno" she declared, before sipping her mug of coffee. Uno promptly bowed, while giving them a small smile, which made him look more doll-like "We couldn't find any host family that was willing to take him in, so we decided to drop by and forc- I mean...ask you to take him in" Said Smith casually.

"It's a pleasure to meet all of you"

The others were somewhat bemused by the news that such a harmless and cute-looking liminal would have such a hard time finding a host family.

"Hmm...? Pray tell, why does no family want to take him in" Rachnee asked with claw on her face.

"Indeed, I must confess, that I, too, am curious aa to why this frail and fragile little boy has not met a suitable host" inquired Centorea while eying the boy, who simply smiled in return.

Before Ms. Smith could respond, Uno simply raised his hand, while eying each and every one of them.

Aside from a slight widening of nearly everyone's eyes in surprise and some gazes of curiosity and wonder (courtesy of Papi and Suu) there weren't really any reactions worth noting. Something that confused Uno to no end.

Tilting his head to the side confusedly (and cutely), he dropped his hand and looked at them curiously.

"Huh, that's weird. Whenever I get this far, this is usually the part where my hosts would either, scream bloody murder, run for the hills, faint or all of the above" Uno mused to himself curiously. "This must be a new record..."

"What do you mean, 'whenever I get this far'?" Kurusu asked curiously.

"My previous host meetings often end with a door slamming on my face when I extend my hand for a handshake" Uno recited monotonously and neutrally.

"Hmhmhm, I hate to burst your bubble, but it's going to take more than that to scare away Honey here" Said Rachnee with a small smile and a claw on her face.

"Evidently, that would be the case"

"Uno, what kind of species are you? I don't think Darling has ever seen your kind on the binders" Asked Miia curiously.

Before Uno could reply, Ms. Smith answered.

"Well, you see, Uno here doesn't exactly have a species that he belongs to per se..." Ms. Smith said idly, while staring her cup. "And he's only a liminal by technicality, so he wasn't born the way he is now"

"I see..." Said Kurusu while eying the petite and doll-like boy.

"hmmm" Rachnera hummed thoughfully, while eying the boy as well.

"If that is the case, then what kind of liminal is he?" Miia asked curiously.

"Oh, he's a W.M.D." Smith replied nonchalantly.

"W.M.D." Everyone parroted confusedly.

"Weapon of Mass Destruction" Uno clarified.

Silence...

"Ehhhhhhh?!"

Yup, that'd probably be my reaction to if I found out my housemate was some sort of ultimate weapon that could potentially wipe out half of the Earth's population.

"Calm down, everyone, it's not as bad as you think it is" Smith said casually and nonchalantly as almost all of the girls started protecting/hugging Kurusu. Papi and Suu were still trying to connect the dots, while Lala remained cool and composed.

"Actually, I think it's worse than what we think it is" Miia said panickingly.

"A weapon capable of mass destruction and potentially wiping out every living being in the planet, I believe tis worse than we think it is" Centorea said, while hovering protectively.

"But it would be so tragic~" Mero said dreamily with hands on her cheeks. "To be the last remaining survivors on Earth. With no one left to hold, but each other and no choice but to fight for their love and to survive as they're hunted down. Such tragedy~"

How in the world can you say that with a dreamy face? Was what almost everyone's mind were thinking at that very moment.

"I'm starting to think that you're actually trying to get Honey killed" Rachnee said with a sly smile.

That's a fair assumption, I mean so far, Smith hasn't really done anything that would make us think of the contrary.

Smith simply waved a hand dismissively.

"Like I said it's not as bad as you think it is" Smith said casually, before sipping her coffee. "So far, Uno here hasn't even so much as hurt a fly and he's a machine that follows his programming, he has free will, so he can freely decide whether or not he will use his weapons"

Translation: He hasn't snapped yet and he can go on a worldwide genocidal rampage if he felt like it, so don't make him angry.

"Besides, does this cute little doll-like boy look like the face of an apocalypse and worldwide extinction waiting to happen to you"

"..."

Yeah...maybe, Smith should've worded a bit less dire...and life-threatening...

"She makes it all sound so grim, doesn't she?" Uno recited monotonously, before sighing. "I'm starting to think that the reason I cannot find a host family is more because of you, than the fact that I am mostly robotic."

"You think so?" Smith was clearly amused.

"Okay then." Said Kurusu casually with a small smile on his face.

"EHHHHH?" Came the response of most of the girls, as well as, several worried and concerned protests, which the young man waved off dismissively and good-naturedly.

"He hasn't done anything that we should be wary of and it would be wrong to turn him down just because of what he is" Kurusu said with a kind smile.

Uno's eyes simply widened in surprise as he eyed the young man.

"I don't understand. Most humans would value their own safety and self-preservation in this situation and yet you seem to be unconcerned with welcoming a potential life-threat" Uno recited with head tilt in confusion.

"Like I said, you haven't done anything that should make people afraid of you" Kurusu said kindly.

"Is my existence as a weapon of mass of destruction not sufficient reason for me to be feared?" Uno asked comfusedly.

Kurusu simply shrugged.

"You are what you are, but like Ms. Smith said, you haven't done anything that would cause any harm, so there's no reason for us to fear you"

At this point, the girls also said their respective pet names for Kurusu dreamily as they watched his harem protagonist char- er...I mean, kind-heartedness shine through.

Uno tilted his head cutely as he considered these words, before letting out a small smile and a cute little giggle, much to the surprise of Ms. Smith.

"Thank you" he spoke cheerily and softly with a close-eyed smile.

At that moment, Papi and Suu decided to jump their new housemate and introduce themselves.

"Hi Hi I'm Papi!"

"Suu!"

Uno didn't seem to mind the two of them jumping on either side of him, if his ever-present close-eyed smile was any indication.

"Papi-nee-chan? Suu-nee-chan?"

"Oooooooh, I've never been a big sister before" Papi said happily.

"Big sister!" Suu exclaimed happily.

As Kurusu and the rest of the girls watched the scene unfold, they couldn't help but feel a tad skeptical and incredulous to the fact that this harmless and cute little boy was apparently a weapon of mass destruction.

"Well, looks like my work here is done" said Smith casually as she adjusted her glasses before standing up to leave.

"We should probably go food shopping now" Kurusu mused to himself loudly. "Would you like to come along, Uno-chan"

"Mhm" he nodded with a close-eyed smile.

"Not with those clothes he isn't" Rachnee mused with a small smile.

"Hm?" Uno tilted his head slightly, before Rachnee proceeded making a new set of clothes for him to wear. Why? Because apparently Rachnee likes making clothes out of her own silk, that's why.

"Put this on" Rachnee said as she gave the boy a new set of clothes, which were conveniently hidden in a clothes bag. Hmmm... Rachnee really went through the trouble of making a clothes bag, huh?

With a small smile, Uno entered a nearby room with clothes bag in hand to change.

A few seconds later, Uno walked out wearing what looked like a middle school uniform. He wore a creamy-brown blazer with a light purple hem, which had black fabric in the collar and cuffs over white long-sleeved shirt. He also wore a brown plaid ribbon around his neck and a black beret that was obviously bigger than usual, but still complemented the look. He still wore his black pants and was now wearing brown shoes.

"How do I look?"

His answer came in the form of a red coils wrapping around him and a certain lamia squealing near his ear.

"So! Cute!" Miia squealed, while hugging the boy, who seemed unperturbed by the force of Miia's hug.

"Kurusu-nii-chan, before we go out shopping, I'd like you to know that living expenses are covered by the cultural exchange" Uno said innocently

...

...

Well, that concludes the first chapter for Daily Life with a Little Brother.

I encourage you all to leave reviews and feel free to follow/favorite this little story.

Also, for a general idea of how Uno looks like and a concrete idea of Uno's new clothes google a picture of 'Tag dimension Blanc' and look for the middle school uniform.

See you all in the next update.
