New Inventor and Tall Neighbor Moving Next Door

It felt like a long time for Izuku, the first time he met Tsuyu after signing for the Inter-species Exchange program and soon invited more Demihuman girls into his home making his and Ochaco's life in the house more lively than ever. Five months, Izuku has been counting the days when the first Demihuman moved in with them, that is almost half a year and it may not seem like a long time to others, but it sure felt longer to him and wonder what kind of things he and the girls will do together next.

"Hey Deku, you doing okay up here?" Yu asked as her body have grown several feet bigger just to see Izuku who is sitting on the rooftop.

"Yeah, no need to worry. I've been doing this sometime after me and Ochaco moved here." Izuku explained.

"Okay, just wanted to be sure. I saw this one video on Youtube about this stunt guy jumping off a roof and it didn't go well." Yu mentioned, the way the guy landed was painful and unexplainable for some reason.

"Thank you for concern, Yu. That really means a lot coming from those precious to me." Izuku smiled, petting Yu's big forehead making her smile and blush a little.

"And I'm also glad that the new upgrade on your shrink-bracelet is working well." Izuku pointed at her shrink-bracelet.

"I know! Now, I can change the size of my body between my original Gigantes size and the Ogre size however I want. It's totally cool!" Yu squealed of joy.

"Just as long as you remember to recharge the bracelet then you'll be fine, it must be nice to be born in a world completely different than a human." Izuku said, looking up at the sky.

"Yeah, it must be pretty cool to you humans that we Demihumans live an exciting though for us, it just how we live our life since the day we were born." Yu chuckled, and turned around to lean her body on the house.

"But ever since humans Demihumans have started living together, we found out that we're not so different from each other despite the outside appearance." Yu said, remembering when she met Nana and told her about the exchange program.

"And it was because we found those connections together, both sides have come closer than ever before." Izuku smiled.

"Man, the world sure went through some big changes for the past three years." Yu smiled back at him.

Then Yu notice something from the front of the Deku house, a truck parked in front of the house right next door.

"Hey Deku, I think we're about to get a new neighbor." Yu informed, pointing at the trunk as he turned around.

"Oh, I guess we are." Izuku surprised as this is new to him.

"Greetings, Deku." Ibara said, coming up to the rooftop with her flower power.

"Hey Ibara, I take it you notice the truck next door?" Izuku asked.

"Indeed, and I was wondering if you could accompany me to greet the new neighbor, I even prepared some nice flowers as a welcoming gift." Ibara showed the pink, yellow, white, and red flowers in her hands.

"Aw, they look so cute!" Yu complimented.

"I'm sure they will love them. Are the others coming as well?" Izuku wondered about Tsuyu, Mina, and Miruko.

"Tsuyu and Mina are coming as they are looking forward to meeting the new neighbor though it was hard to convince Miruko to come, but she agreed to come as she wanted to see if there the new neighbor is a strong fighter." Ibara explained.

"Even though she is still not allowed to attack humans until the bill says otherwise." Izuku stated.

"You know how that rabbit woman is with the fighting and showing off." Yu said.

"Come, the others are already at the house waiting to greet the newcomer." Ibara gestured to come.

"I'll call Ochaco later to let her know." Izuku said.

"Oh, let me help you down." Yu offered moving her finger to Izuku, but accidentally pushed him a little too hard that cause the dark green-haired young man to stumble forward and land right onto Ibara, with his mouth onto her left breasts on the nipple.

"Oh my, Deku!" Ibara surprised and Izuku's face turns nine shades of red of the embarrassing position he is in and quickly pulled himself away.

"I'm so sorry! I didn't mean to…?!" Izuku panicked.

"Do not be afraid, I am not mad or anything, it just felt good." Ibara blushed smiling.

"(Fuck! That should have been my nipple in his mouth!)" Yu thought angered of jealously as she bit on her nail.

After calming himself down from the little sexually accident, Izuku and his monster girls are now standing outside of the house seeing some men, both humans and Demihumans, moving some furniture from the truck into the house and some other stuff they're bringing in too.

"Wow, look at those fancy gizmos." Mina complimented, seeing few machines and some boxes of tech tools.

"Whoever is moving in must be into tech, probably a university scientist." Tsuyu guessed.

"Seriously, I was hoping to see some backbone in this one." Miruko disappointed that this new neighbor may not be a fighter.

"Now, now, not everything is about fighting." Ibara pointed out.

"Do you think this could be an important secret agent gadget." Mina asked, holding a red metal ball in her hands.

"Uh, where did you get that, Mina?" Izuku asked.

"I got it from one of the boxes those movers were carrying." Mina answered honestly.

"What?! Mina, that's stealing! You should know better than that." Izuku scolded as he quickly snatched the metal ball away.

"I'm sorry, I was just so curious about those gadgets we saw, and I just wanted to know how they work." Mina apologized, pulling the innocent puppy eyes.

"Plus, can you really blame me for when I used to live alone before coming here. I never got to learn anything else while growing up." Mina said, looking at Izuku and the other Demihuman girls.

"Just as long as you understand, don't do something like this again." Izuku said.

"Besides, I don't think this little ball is harmful." Tsuyu added.

"Unless you want to be blown up into little pieces." A woman said walking up to them.

"IT'S A BOMB?!" Izuku panicked accidently throwing the ball into the air and quickly brought the girls together to shield them.

But nothing happen as the metal ball lands in the hand of the young woman.

"Joking." The woman giggled.

Izuku started to realize that he looks around seeing that he and his monger girls are still okay, and no explosions went off and turns his head to the woman.

"Sorry about that, a friend from my old college told me to do this for a little laugh. Didn't mean to worry you like that." The woman explained.

"Izuku, you can remove your hand from there." Yu blushed, Izuku look at his left hand on her big breasts quickly removing his hand freaking out of embarrassment and quickly turn his attention to the new woman.

"My name is Melissa Shield, I just moved here, and I hope we can be friends." Melissa introduced herself to them.

Melissa is a full-figured and attractive pale-skinned young woman of slightly above average height with quite a round face. She has wavy blonde hair which reaches halfway down her back, two shorter pieces she leaves over her shoulders, side-swept bangs that frames her face, aqua-blue eyes with notable upper eyelashes, some slightly longer ones extending on each side and pronounced lower eyelashes. She wears a red tank-top shirt with a long V-neck that exposes part of the top cleavage and a little of the middle part, pale light-blue skirt, white lab coat, and brown high heel shoes. She also wears a red wristwatch and pink, oval-framed glasses. Breasts sizes: I-cup.

"(Wow, she's beautiful!)" Izuku thought complimented, and his eyes wander to her cleavage and quickly look away.

"N-N-Nice to meet you, w-welcome to the n-neighborhood." Izuku stuttered with his cheeks blushing a bit.

"Thank you, and again I'm sorry for the little joke. Though it was really nice to see a host willing to protect his Demihuman family like that." Melissa commented.

"Well, duh, Deku has the biggest heart in the whole world!" Mina bragged.

"Yeah, bigger than me you could say." Yu smiled as the others nod.

"And always know when to help in need even to those said who won't admit her heart has been healed." Ibara added, looking at Miruko who just looks away blushing a bit.

"So, do I get the name of the wonderful fellow hoist?" Melissa asked.

"Oh, right, I'm Izuku Midoriya and these are the Demihumans I'm currently hoisting." Izuku said and gestured to his monster girls.

"We'll introduce ourselves in order. I'm Tsuyu Asui. Ribbit. I'm a humanoid frog girl." Tsuyu greeted.

"Yu Takeyama, I may not look like it but I'm a Gigantes that can change size with this shrink-wristband." Yu said showing her wristband.

"Rumi Usagiyama, but I like to go by Miruko the future Rabbit Hero of the world." Miruko smirked.

"Mina! The slime girl who likes to have fun none stop and be happy with friends!" Mina giggled hopping of joy meeting a new friend while stretching her arms into a large heart shape sign with one foot bend backward and through the heart like an arrow piercing through it.

"I am Ibara, a Dryad, and I offer you these flowers of welcome and peace for a sign of friendship." Ibara presented the flowers handing them to Melissa.

"Wow, these look pretty. Thank you!" Melissa thanked; she sniffs the flowers finding their scent together to be amazing.

"It's so nice to meet such wonderful people welcoming me even though I haven't finish unpacking yet." Melissa amazed as she believes to have made some new friends already.

"Of course, we're always looking for new friends to play with!" Mina smiled.

And then Izuku realize what Melissa said a little earlier before the introduction of himself and his Demihuman girls.

"Hold on, you said "fellow hoist" then that means you have a Demihuman with you too." Izuku figured out.

"That's right, my Demihuman is currently inside helping some of the men with the boxes and my gadgets." Melissa nodded.

"Oh, can we meet her?" Mina excited, leaning her extending neck to the new woman's face.

"Amazing, I have of special breed of slimes that can take on more human appearance than the normal ones, but your appearance is something else." Melissa commented.

"Why, thank you! I've been told I'm a special case!" Mina smirked with a giggle.

"Probably to yourself in your former lonely life back in that hotel you mentioned." Tsuyu blurted out, making Mina gasp.

"Hey! No need to tell her that!" Mina complained causing the others to laugh a little.

"Hey Melissa, where did you say you wanted these metal capsules to go?" A woman called out from inside the house.

"In the basement!" Melissa responded.

"Oh, is that the Demihuman?" Miruko asked.

"That's right, we've been together for about a year now and I just graduated from Tokyo University." Melissa mentioned.

"Hey Tionishia, come on out and greet our new neighbors!" Melissa called out to her Demihuman.

"Okay, just give me a sec!" Tionishia answered.

A few seconds later, the tall figure comes out of the house and moving past the mover men.

"Tio, these people are Izuku, Tsuyu, Yu, Miruko, Mina, and Ibara." Melissa introduced them.

"Hi there, everyone. My name is Tionishia, or Tio for short, and I'm super excited to meet you all!" Tionishia greeted cheerfully and exciting.

Tionishia is a very tall woman with tan skin and long flowing hair that goes down to her hips. She has fangs, pointed ears and very large breasts. She also has a single large dark purple horn in her forehead, which connects directly to her skull. She wears a red French hat on her head, yellow short-sleeve jacket, white shirt with most of her top cleavage expose, pale peach-yellow long skirt, and brown shoes. Breasts sizes: P-cup.

"Oh wow, you're an Ogre, and a strong-looking one too!" Izuku impressed.

"Thank you, I do try my best to be keep my body in tiptop shape." Tionishia giggled and shake her body a little causing her breasts to bounce.

"Damn, you got such huge jugs!" Mina commented out loud.

"(So, in my true form, I'm way better than her.)" Yu thought as this girl is only one cup ahead of her in her smaller form.

"Say, you wouldn't mind going up for a little sparring match with me because I plan on kicking any strong opponents' asses." Miruko challenged Tionishina to a fight.

"Huh, what?" Tionishina confused and a little scared too.

"Sorry about Miruko, she likes to fight sometimes, but I can assure you that she is a very kind-hearted woman who would risk her life for others." Izuku vouched with a confident bow.

"Hey, no need for all that mushy stuff. Idiot." Miruko stated, but on the inside, she is glad to hear such kind words from her hoist.

"So, if you're a scientist then how come you're settling in a peaceful place than being in a big laboratory?" Tsuyu asked curiously.

"Well, I have been studying some engineering and science together, I actually like to be in a quite peaceful places that help calm my nerves when I want to make new inventions like the shrink-wristband my father made." Melissa pointed at Yu's wristband.

"Uh, your dad made this?" Yu surprised.

"Yep, he's the famous scientist who helped make new things to help the Demihumans that have unique bodies or conditions to fit into other places better. David Shield." Melissa revealed.

Suddenly Izuku grab her by the shoulders and shaking her like crazy.

"No way! David Shield! The brilliant and greatest scientist in the WHOLE world, the man who was one of the founder peace makers for the Demihumans and Humans coexisting. The man who was also the top student in the private island of science, I-Island where he created special items for certain Demihumans like waterproof clothes for the underwater ones and clothes that can stretch got those that are large than the others!" Izuku mumbled on and on of excitement weirding out Melissa a little.

The smarty mumble was stopped when Miruko karate foot chop Izuku on the head.

"Sheesh, Deku, you really need to cool down that habit of yours." Miruko exclaimed.

"But we all agree that it's what makes Deku so cute." Ibara reminded them of that talk they had some time ago.

"Huh, Deku? I thought his name was Izuku?" Tionishia confused.

"Oh, well, Deku is a nickname I go by when it comes to friends and other close to me. I know it's weird, but I actually like it now these days." Izuku explained a little.

"Well then, the sound of "Deku" is really cute and you're such a cutie yourself." Tionishia complimented making Izuku blush.

"Yeah, from just looking at you. The name does seem to fit even though the meaning is useless." Melissa nodded.

"Hey, Melissa and I were thinking about doing a little party to celebrate of moving in. You want to come?" Tionishia offered them to come over.

"Oh yeah, I love parties!" Mina cheered.

"By the way, if it's not too much to ask: what does that little box do?" Izuku asked curiously.

"It's a working prototype, but this is like a flying flashlight that can float around you can making bright light whenever you're in a very dark place." Melissa explained.

"Oh, that's amazing." Izuku amazed.

"Yeah, but the problem is that…" Melissa pressed the top button as the metal starts flying in the air as the others became amaze.

But it exploded into pieces with a puff smoke causing Melissa to fell on her butt.

"As you can see, the ball exploded whenever I try to make it work, but I always kept trying until I get it right." Melissa informed with determination in her face.

"That's right, Melissa has never been the one to give up so easily." Tionishia said and then gasp.

"Melissa, it's Izuku-Deku! You're sitting on him!" Tionishia blushed.

Melissa looks down seeing Izuku's face right below her smooth big butt, both her and Izuku are blushing like crazy as he tried moving his mouth which only made her moan a little.

"I'm so sorry, I had no idea how that even happened!" Melissa apologized as she quickly got off him.

"I-It's okay, nothing bad happen." Izuku embarrassed.

"That kind of reminds of how we ended up on each other's bodies." Tionishia mentioned.

(Later Tonight)

Everyone is gathered in Melissa and Tionishida's new home along with Ochaco who came home a little while ago, cheering for becoming friends and hope for a bright future together.

"No way, you graduated from Tokyo University earlier than everyone!" Ochaco gasped.

"Yeah, guess I like to go forward fast." Melissa giggled.

"Come on, you must be interested in sparring." Miruko said to Tionishia.

"I rather not." Tio rejected.

"Well, it looks like everyone is having fun." Izuku smiled.
