A/N: our timeline here in this fic: day 1 [garou battle]; day 2 [hospital visit]; day 3 [meetings]; day 4 [esper sisters]. This chapter is still in day 3.

If you find any misspelling or ungrammatical statements or phrases...well I don't have a beta and english is not my first language. So take a chill pill and point out the mistakes in the reviews. Correct me in the same exact way you'd like to be corrected. I don't mind. Same applies if there are any inconsistencies. I'd appreciate if you point them out. Thanks!

. . . . . . . . . . .

Genos..not.

On their way to Saitama's unit- room 104- our hero is still sweating bullets. Why?

"um..King?" he began, "I tried looking for a replacement but... the game I borrowed, it's broken." He proceeded to show him the said item. "I'm really sorry."

"I don't mind" King quickly eased his worries. The lump in Saitama's throat vanished like my ex's love for me in a span of like, approximately 0.005 seconds. Kisapmata. "I came 'cause I thought we could play that new fighting game as a house warming party. I didn't know you went out, Saitama bro."

"No way," the baldy responded, "you always go all out even on noobs."

King deapanned for whatever reason he had and said, "oh well, it's about time I feed my goldfish for today, so I'll head home now. I'll be back tomorrow."

"Okay, see ya. Btw, thanks for the save earlier, dude."

"No prob Saitama bro."

The A class rank 39 hero Caped baldy was about to enter his new unit when he noticed that a package has been sitting just outside his door. Hmmm.. this was not here earlier.. who could have sent it?

"Huh ? whaz diz?" BS asked.

"Oh? You're still here? Saitama asked him in return. "oh well, whatever. I'll let you stay just for tonight, however, I'll be making a dog house later. So expect me to kick you both out tomorrow, got it?"

The... helpless animal wanabee nodded furiously while Rover barked once qand wagged his fluffy tail.

10 minutes later..

"Okay, let's see what we've accomplished for today," Saitama declared, "putting goods inside the fridge check. Restocking pantry, check. Keeping stuff-I-don't-need-yet away, check.."

"We were alzo able to get theze packagez inzide, zo now wut?" BS asked.

"Geez, so impatient, what's your name again?" the bald asked in return.

"Bla—. You can call me BS." [Bee-Ehz]

"Okay Biz, calm down, I'm still thinking." Our hero is now seated in the middle of his living room, cross legged and arms crossed across his chest staring at the four large boxes.

"How about we check theze boxez out, eh bozz?"

The man ignore him for a moment before exclaiming, "I got it! We'll check out these boxes." BS sweatdropped. So his strength is inversly proportional to his I.Q.?

And so, the two thoroughly inspectioned the boxes.

"Hey bozz, derz a note here. 'Tiz addrezed to you." BS handed him the note.

The bald man eyed it suspiciously. It was a bit bulky to be considered just a 'note'. More like a telegram... he sighed. What harm could it possible bring? And since the enveloped clearly shows that it's addressed to him, he had no choice. Damn.. I hate reading. Mangas and sales leaflets not included.

"oh it's a letter from Genos."

Dear Saitama –sensei, it is my utmost regret that I could not be with you as of the moment. Dr. Kuseno has informed me that the damages I incurred during that battle with the self proclaimed, Kami Level Threat Garou has rendered almost my entire mechanized body useless. Hence the need for an overhaul. Dr. Kuseno has seen this a glorious opportunity to upgarde the existing mechanisms and..

I will be back as soon as possible sensei. Dr. Kuseno's estimate is around 3 days.

Until then sensei. Please take good care of yourself., sincerely, Genos.

A/N: what? Genos is a verbose guy. Saitama skipped those parts. So should you.

That Genos. How many times do I need to tell him to summarize it in 20 words or less? The bald hero's eye was twitching. How the hell did that cyborg know his room # anyway?

Okay. So these boxes are robots? Hmm.. how to activate these stuff.. our hero looked for that information in the letter. He followed the steps and... okay guys, imagine transformers.

~One eternity later~. [imagine that SAME EXACT voice in spongebob that says this.]

The strongest man in his universe was in an indian sit position staring at the four robots. Who, in turn stared at him as well. Eight robotic eyes stared at him. how intense is that? How did he end up in this situation again? Oh yeah, he followed Genos' instructions.

"Sensei!" "Sensei!" they chanted and ran at him.

For the first time in his life, Saitama realized how troublesome it is to be tangled in a mess of robotic limbs as they toppled and tangled him. This was supposed to be a hug guys.

"Ugh! Get off me!" he yelled.

The 2 monsters sat in the farthest possible corner of the room. These robots could possibly possess scanners and stuff that detect monsters and turn them into fireworks. They decided not to push their luck for now and wait for a chance to test the waters. Lay low... hibernate.

"Hai sensei! Immediately." The tallest one said. He stool on full attention. (the one you do when you squad commander barks, 'attention!') heels together, big toes 45 degrees apart. He stood in front of this sensei who has now begun to regain composure after the rather... intimate welcome. The rest of the robots followed. They also stood on full attention, hands on their sides, big toes 45 degrees apart. Except for the smallest one. It was his heels that were 45 degrees apart and his big toes that were close to each other.

"What are you doing here anyway?" the man gave a lackadaisical yawn.

"Saitama-sensei, Genos-shishou should have been able to thoroughly explain our presence here in leiu of his, as the damages he has incurred on his previous battle had rendered most of his body almost useless. But rest assured sensei, we do appreciate that you wanted to hear the reason straight from us personally. You truly are an amazing person." He bowed, making a perfect 90 ° angle. "My name is Hono, first prototype for fire-based powered robots. My body should have been the first used by Genos-shishou, however, his brain is not compatible and upgrades demanded that I become my own person. Nevertheless, has implanted Genos-shishou's memories of you in our system so that we may be able to assist you and function to your convenience!"

The Caped Baldy eyed this boy. He was as tall as a 13 year old boy, wearing a gakuran. Middleschool uniform for boys that includes a long sleeved black shirt paired with black slacks. (imagine Shigeo Kageyawa from Mob Psycho 100 with Ino Yamanaka's hair shaped like Ichigo Kurosaki. Looks like king/Harlequin in nanatsu no Taizai when angry). He had the same eye color as Genos.

"Oh, okay Hono."

"S-s-sen-s-sei.. I...I a-am H-Hana. A p-p-roto-t-type for a female cyborg. M-mmy b-body h-has w-wat-t-ter b-based attacks. A-as w-w-ell as wind." The girl stepped forward. She had white hair, hime cut (she looks like young Hinata Hyuuga with white hair). She wears an oversized skyblue shirt with chinese collar that reaches an inch above her knees and two slits on each side. One inch slits. The sleeves were one inch past her elbows. Her eye color is the same with Genos and Hono.

"Do you also have memories implanted onto you as well?"

"H-h-hai s-s-ensei. A-a-all of us. H-however, w-w-e h-have d-d-ifferent personalities. And t-the m-memor-r-ies were not implanted. It was o-only the c-c-ase for Hono-kun. The t-three of u-use watched Genos-shishou's m-m-memo-r-ries of y-y-ou" She tried to be as polite as she could.

"Next."

The fatso stepped forward, "SENSEI SIR! I AM RAI! " this one wears a green hoodie with short sleeves. "MY BODY'S ATTACKS ARE BASED ON LIGHTNING, ELECTRICITY AND ELETRICAL CURRENTS! I AM EQUIPPED WITH MISSLES AS WELL SENSEI SIR! PLEASED TO BE OF SERVICE!" If the girl is as tall as a 12 year old, this one's probably as tall as an 8-year-old. Overzealous too.

"I AM ALSO A TANK TYPE ROBOT SENSEI SIR! WHILST HANA IS FOR SUPPORT, HONO FOR OFFENSE, I AM PRIMARILY FOR DEFENSE SENSEI SIR!" dumb brat salutes everytime he says 'sensei sir'.

Saitama tried to clean his ears with his pinkie. "Carry on." He drawled. This boy has green eyes and red hair. He wore a pedal reaching 2 inched below his knee and sneakers.

"hmm.. okay Rai.. but please tone it down. I love my hearing, thank you very much."

"HAI! SENSEI SIR!"

The smallest one stepped forward after the other stepped backward. He looks like a mini- Fubuki. "I'm Yuki." He stated. He was as tall as a 3 year old. Wears a mint yukata. Has bluegreen eyes.

"Yuki has ice based attacks SENSEI SIR!" guess who.

"T-that i-is t-t-rue. I'm tasked t-to t-take c-c-are of him together w-w-tih h-h-ousehold chores as well as repair and m-m-aint-t-enance of my fellow robots." Hana offered.

"Though Rai has mentioned that he's built primarily for defense he meant infrastructural barriers, it will be my duty to defend you sensei, in combat and from intruders. Also, Rai will be incharge of cooking since has programmed him with such and downloaded a plethora of cookbook manuals in his system." The boy declared.

BS' thoughts were along the lines of oh zhit oh zhit oh zhit...

"you're all robots." The man noticed.

Cue everybody sweatdrop. "Really bozz? I didn't notice." Bs muttered. I'm zoooo dead. Four sets of gaze scrutinized the teletubby look-alike.

"oh, that's Biz. He's my helper. He just barged in. And no, Hono, he's not a threat. The dog's name is Rover". The caped baldy introduced.

"nyz to meet ya!" Biz waved.

The four faced him again and altogether bowed, "please take care of us!"

"Actually sesnei, it is only I, Hono, that you can consider robot. Or, since dr. Kuseno has seen to it that I become self aware, you can consider my an android, while those three are cyborgs. Rai and Hana came from the same village as Genos and were on the verge of death when Dr. Kuseno found them while Yuki is formerly an 8-month old infant found in the dumpsite near Dr. Kuseno'sa laboratory." The school boy explained.

"so you're Genos' temporary replacement huh..." our hero has his normal bored look on his face and is now staring into space. The three older looking kids nodded. 3 because Yuki nodded furiously.

"But you all look like children!" the man complained. True, Dr. Kuseno did not intend them to be combat type anymore ever since Genos is already a combat type cyborg, so he equipped their entire bodies with synthetic skin making them look like normal children. The only metal part of them are their metal palms.

"C-c-child-d-dren?" – Hana parroted.

Hono's chest buzzed. [assessing installed dictionary. Word inquiry: children] "noun." The boy declared. "Plural of child. Synonym: offsprings. Characteristics: immature, fickle, short limbs, under care of parents/ legal guardians."

"Oh? A definition less than 20 words?" Saitama was amazed.

"SENSEI SIR! If we are children and we are under your care, does that mean that you are our parent?" Rai eagerly asked, kneeling to sit beside him.

"oi, don't you think it's redundant? Sensei and sir?" the guy scratched his bald head.

"a male parent is called a father, daddy..etc.." Hono droned.

"Daddy sensei!" Yuki ran to him.

Now, Rover may be a monster but he does not speak. He may have been a dragon threat but his intellegence is way below that tier. Hemay have been a monster and still is, but his instincts are that of a dog. And the sight of this small newcomer trying to tackle his new master with it's stubby arms did not sit well with him. He pounced to intercept. His master's eyes widened. All hell broke loose.

Hono automatically fired a fireball on Rover, while Rai created a an electromagnetic barrier around them so that his sensei's belongings would not be destroyed and then ran in fury to get Rover away from Yuki. Hana tried to defend Yuki with a water blast via left hand and a gust of wind from her right- which in turn enlarged Hono's fire ball and destroyed Rai's barrier. The result?

CRAAAAAAAAASSSSSSSH!

"NO NO NO! Hono ! STOP STOP Hono -! CALM DOWN -! Yuki! Yuki! Hana HELP!" the bald man bellowed "Raiii! Don't eat Rover! You-" he was caught in the blast.

He was gagging in smoke. He tried to get out of the room to prevent himself from suffocating. He kicked the door as gentle as he could as to not break it and almost crawled his ass out. Damn brats. He heard them still talking amongst themselves. Rover barking at Yuki who is now on the arms of Hana still sporting an innocent look, while Hono is trying to stop Rai from eating Rover.

"If SENSEI SIR is our father, then who's our mother?!"

"I-i-t can't be S-Shis-shou can it?" Hana asked.

"A mother is a female parent and shishou is definitely male." Hono commented.

"I-I remem-b-b-ber having a m-m-mother be-f-f-fore..."Hana wanted to cry.

Outside, they stared at their adopted father having a coughing fit and is now being assisted by a woman who looks suspiciously like Yuki.

"Mommy!"

Oh hell no.

30 minutes later~

Everyone helped in fixing everything. Our favorite bald hero is just lucky I'm the author and his room got minimal damage.

So now, they are seated in front of the table eating hotpot courtesy of Rai using the ingredients Saitama brought this morning and the steak that Fubuki brought. They also had rice and mango juice requested by Yuki.

"So let me get this straight, Genos needed a full body repair, and in his place sent these 4 to take care of you. And this teletubby lookalike together with your new dog just tagged along with you on your way home. Is that correct?" Fubuki asked. Saitama perfunctorily nodded, busy with the food. Sounds like bullshit to me.. they better not interrupt my Saitama-time or else...

"Would you like me to zay' believe it' ? " BS blurted out.

"Wnd you are?" the sleeveless clad esper glared at him.

"B-b-b-b S!"

"He's Biz. He's gonna be a helper around here. I dunno what kind of animal he is, but.. you get the point. I'll be building a dog house later and he can stay with Rover there." Saitama informed her. " by the way Fubuki, please take note that Hono is a pyromaniac, Hana stutters, Rai tried to eat my new dog and Yuki's practically a toddler."the A class hero continued.

Hono, Hana and Rai hung their heads low and immediately spiralled downward into depression. The three retreated to a corner and sulked complete with storm clouds hovering above their heads. (imagine Hashirama when depressed)

"Oi!" the baldy called out. Even he noticed the depressing atmosphere. How can robots be depressed anyway? He looked down on Yuki. His eyes were misty. Was this part of their program?

"D-d-adddy?.. no daddy?" the little boy croaked. Trying to choke a sob. Key word trying. Yuki then proceeded to sob, cry and eventually bawled his eyes out in a span of approximately 7.5 seconds. The man felt a twinge of guilt and tried to comfort the said boy. However it was in vain. As the boy seemed inconsolable.

As the scene continued to unfold, Biz tried so hard not to ROTFL. Rover was just confused. Wasn't this man-puppy trying to attack his master earlier? Now his master is trying to cuddle it. What the hell? Fubuki tried to stifle a laugh.

Now, Saitma may not be the shiniest egg in the carton, but he has exceptional observational skills, especially when he's not being dense, a.k.a OOC. He noticed the woman stifling a laugh. Dumb bitch. Hmmm. His eyes traveled around before returning to Yuki. He had a lightbulb moment. Payback time..

"Okay, Okay.. I was just kidding. Kidding, see? Show daddy your smile eh? C'mon Yuki" he cooed. Suddenly all of the storm clouds dissipated and Yuki's face brightened. "Daddy!" Yuki clung to him as if his life depended on it. The new father's gaze shifted to the other three sulking in the corner looking at him expectantly. "Alright.. I'll father you guys too." Maaan. A father of four and no girlfriend since birth. Tough luck. And in a blink of an eye, he was again tangled in a mess of robotic arms that sanked its way around him.

"Chichi ue!" "O-otou- s-s-sama!" "SENSEEEEEIIII SIIIIIR!"

"welp. Okay, okay, get off me now and... go bug your mother." He smirked.

Jigoku no Fubuki's eyes went the size of dinner plates.

"As you wish chichi ue!"

"HAI SENSEI SIR!"

"Oka!"

"moooooommmmmmyyyy!"

The four of them fervently announced and pounced at Fubuki while our hero ate.

. . . . . . . . . . .

A/N: Teehee ^.^

didja like it? Didja? Didja? These guys are my OC. Comment your complaints, compliments and humdudgeons and suggestions. Comment or Yuki will die! Hehe just kidding.

Hey guys, this fic will be a love triangle. OR SQUARE WHATEVER. One sided because Saitama isn't interested in lovelife yet. He hasn't found a good challenge yet, dammit.

Please place on the reviews your prefered heroine: Senritsu no Tatsumaki or Jigoku no Fubuki? Genos is a given, but it'll be platonic, so no lemons. And besides, I'm not good with making lemons. Sorry to disappoint.

I'll update as soon as'm done typing the other chapters!
