Izuku cringed. His shoulder still twinged with pain from last week's excursion. He gently rubbed it with his hand, before continuing down the sidewalk toward the department store. Izuku had wanted to get Katsuki a new jacket for the holidays. It was two weeks before Christmas, and he had hoped to get the blond something last month.

A cold wind ruffled his scarf, almost blowing it completely off his shoulders. Izuku held it tight, and turned away from the bustling wind. Just as he turned up, he immediately saw a hoard of animals stampeding toward him. "What?!"

An elk bowled him over, and he was suddenly looking down at different kinds of paws, and hooves raging toward him. Even people were running amongst the animals, trying desperately to get away from whatever was causing so much chaos. Izuku quickly rolled out of the way, and then crouched as close as he could to the nearest wall.

He waited until the stampede had moved on before standing, and observed his surroundings. There was no one left! Further more, there wasn't a zoo around for miles! As he looked down the street from where the animals, and pedestrians had come, he could see a loan man approaching him calmly. In his arms there was a small, white rabbit trembling with fear.

"Who are you?" Izuku asked cautiously.

"It's only polite to introduce yourself first," the stranger stated. He sat the rabbit down, and allowed it to scurry away.

"You're obviously a villain," Izuku responded. "Once again, who are you?"

The stranger gave a toothy grin, his eyes widened manically. "I AM in fact a villain! I am one of the three Henge Brothers! They know me as Dobutsu, the second youngest!" He swung his arms out dramatically, did a small twirl, as if he could hear an applaud just for him, and bowed before Izuku. "And today, my friend, is not your lucky day!"

Izuku panicked slightly when Dobutsu suddenly transformed into a falcon, and dived for him. He ducked out of the way before the sharp talons came in contact with his scalp. Izuku threw his arms up over his head, and tried to run into one of the stores.

Dobutsu changed again; back into a man, and landed in front of the door Izuku had been heading for. He extended his hand, awaiting for Izuku to make contact with him.

As he had expected, Izuku didn't notice him in time, and collided with the Henge brother.

"Itsy-bitsy-spider, went up the water spout!" Dobutsu exclaimed excitedly.

Izuku squeaked as his world suddenly started to get bigger, and his clothes were falling off him. The sudden urge to run away like a coward hit him like a truck. Hidden within the mountain of clothes, Izuku knew there was something out there bigger than him, and quite capable of stepping on him.

The clothes were lifted away, revealing the man who had done this to him. He raised four forelegs, trying to appear bigger, and hopes to scare the human away... Wait... four forelegs? How many legs did he have? Izuku let out a tiny screech when he realized he was a SPIDER!

Dobutsu chuckled as he knelt down in front of the green, fuzzy arachnid. "You're cute for a tarantula," he cooed. He laid a finger on Izuku's back, pinning him down easily to the ground. "However, I'm the only human who would ever think that. As soon as another person sees you 'squish.'" Dobutsu laughed mockingly. "I could do it now... But I wouldn't hurt a fly." He stood proudly, and made to walk off. Suddenly, someone punched him hard in the back, and laid him flat on the ground. Dobutsu grunted when that same person stomped on his head, successfully knocking him out cold.

It was Aizawa!

Izuku scurried about frantically on his eight legs, not knowing where to turn, or run. A familiar scent caught his attention from behind him, and flipped around to face Toshinori. If he had been human, he would have cried happily.

"Midoriya, my boy," Toshinori greeted, albeit concerned. "What has he done to you?" He gently lifted the spider up in both hands, and watched Izuku's comical motions carefully.

Aizawa frowned. "I canceled Dobutsu's quirk. Why hasn't he changed back?"

Toshinori shook his head. "No idea, Aizawa. Maybe it was like before. There's probably a cure for it."

Izuku, who had been waving his small arachnid-arms about excitedly, suddenly felt crestfallen. Another cure? But who, other than Toshinori, would want to cure a spider? He let out a small whimper, which his former teacher seemed to have heard.

"It'll be alright, my boy. We'll find that cure. When Dobutsu comes around, we'll get the information from him," Toshinori explained, and out of habit, started petting Izuku on the back.

A purr erupted from his fuzzy frame. It actually surprised him that a spider could even make that sound.

s s s

Katsuki stared down at the furry, eight-legged, creepy-crawly reaching out toward him, as if actually TRYING to provoke him.

In this case, it was exactly what Izuku was trying to do. The horrified expression on Katsuki's face was priceless. His little body started to bounce slightly in an attempt to laugh.

"You're making fun of me, aren't you, Deku?" Katsuki growled, before slamming a hand down next to Izuku, which caused the poor spider to jump, and scury back to Toshinori to hide in his coat pocket.

"Stop it, Bakugou," Aizawa scolded. "He's only trying to let you know it'll be alright," he lied. Of course he knew Izuku was taunting the young blond.

Toshinori sighed as he dug the sulky, Deku-Spider out of his pocket, and set him back down on the table. "We need to figure this out. Dobutsu won't tell us the cure. We can't just torture him."

Aizawa smirked. "I can."

Everyone looked at him in shock.

"Kidding," Aizawa said drolly. "Just kidding."

"Bakugou, we need you to take care of Midoriya while we figure this out," the former hero instructed. "Hopefully, you won't have to do it for long."

Katsuki gave the man a disgusted look. "I am not taking that creature home with me! If I don't kill it first, I'm sure my landlord will! And why me?!"

Izuku sat in front of Katsuki, giving him the biggest puppy dog eyes he could muster for his small size.

The young blond frowned, before rubbing his face with both hands in frustration. "FINE! I'll take you home with me, but don't expect me to hold you in my hands."

Izuku shrugged, and ambled up the other's arm to sit on his shoulder. He felt Katsuki flinch.

Oh, this was going to be fun!

s s s

On the way to Katsuki's home, the blond tilted his head to get a better look at the Deku-Spider on his shoulder. "How could this have happened to you? You're not usually so careless, Deku. A spider of all things? Really? Why couldn't you be a cat...or a bird? At least you'd be less creepy."

Izuku rolled his eyes with exasperation. 'Like I had a choice in the matter,' he thought to himself.

When they finally reached their destination, Katsuki unlocked his apartment door, and slipped in quietly. It was late, and his neighbors were probably already asleep.

Forgetting that Izuku was sitting on his shoulder, he pulled his shirt off, and dropped it to the floor by the sofa.

Izuku hissed in frustration, and chased after Katsuki. He pounced on the blond's leg, causing the man to jump about frantically, and tried to shake Izuku off.

"Goddamnit, Deku! I'm sorry!" Katsuki yanked the spider off his leg, and begrudgingly held the small creature in his hands. "I forgot you were there. Stop getting upset." The scowl Izuku was giving him was almost too cute, and the blond couldn't help but snort at it. He then sighed in defeat. "I'm going to take a bath You can stay in here until I'm done."

Izuku tapped four of his legs impatiently against Katsuki's palm like he would do if he had fingers. He wanted to go too.

"What? You're not going in the bath with me. That's gross." Katsuki sat Izuku down on the back of his couch, and retreated to the bathroom.

Deku-Spider jumped up, and down frantically, before he launched himself to the floor, and scampered under the bathroom door. Izuku stopped dead in his tracks when he saw a gloriously naked Katsuki sitting on a stool, and using a shower-head to bathe himself. All he could see was his back, however. He swore if he wasn't a spider, he could feel his whole body light up like a red Christmas tree bulb.

Katsuki yelped when Izuku ran past him to the bathtub, climbed up the side of a hamper, and leaped to the bathtub's rim. The tub was already full of warm water much to his satisfaction, and started to use his small appendages to gather water droplets, and wash his body. "Deku," Katsuki scolded. "I told you to stay in the sitting room!"

Izuku flicked water at the blond in retort.

"Hey," Katsuki laughed, and caught himself too late. "You damn spider! If you weren't my comrade, I would be using a newspaper on you by now."

The spider hissed mockingly, and waved his appendages at the blond, while trying to keep his balance on the edge of the tub.

Katsuki hid the smirk on his lips as he approached the tub, and slid into the water. He took a deep breath as the warmth immediately started to relax his aching muscles. "What a day," he muttered. "Teenagers can be such a pain."

Izuku made his way across the rim of the tub to Katsuki's side, and patted his arm in a friendly gesture.

"Thanks, Deku." Katsuki peered over at the spider, a look of sympathy in his eyes.

Was that a smile? It was barely noticeable, but it was there.

Izuku leaned over onto the blond's shoulder, and stroked the side of Katsuki's face.

Katsuki suddenly jolted at the contact, causing Izuku to fall into the water.

Izuku floundered about, frantically trying to find the side of the tub again.

Katsuki lifted him to safety with a hand. "Sorry," the blond apologized sincerely. "I know you're Deku, but it doesn't change the fact that you're a...spider."

Izuku shook out his legs, and then the rest of his body with a huff. So much for thinking that Katsuki was getting used to him.

Said blond sighed, and quickly finished washing himself, got out the tub, and dried off. "Let's go to bed, Deku."

Izuku leaped to the floor, and raced across the bathroom to Katsuki's bedroom. It was easier to the climb the bed sheets, since the hairs on his legs clung to the fabric. He curled up on Katsuki's pillow, but noted the unease on the other's face. Izuku made to move, but was stopped by the blond's hand.

"It's okay. You don't have to move. I know you want to be comfortable too." Katsuki scratched the back of his neck anxiously, before settling down on the bed, and laying his head next to Izuku. He closed his eyes, and sleep took over effortlessly

Izuku listened for the blond's even breaths. He crept closer to Katsuki, and nestled in the crook of his neck, and shoulder. He purred softly as he followed the other's lead.

s s s

Katsuki's opened his eyes calmly to the sunlight filtering through the blinds in his room. His ear twitched at the sound of something purring close by. He automatically tensed when he realized it was Deku-Spider nestled up against his skin. Katsuki grit his teeth before letting out a horrified scream!

Izuku flailed at the rude awakening, and rolled off the pillow to the floor with an undignified squeak. What the hell was that for?

"Deku, I fucking hate you! I'm going to kill you!" Katsuki threw his feet over the side of the bed, and stomped the floor unnecessarily hard on either side of Izuku.

It obviously worked in intimidating the green spider, because he scurried out of the bedroom like a bullet.
Katsuki rubbed his face hard with both hands. He had woken up from a particularly disturbing, yet erotic, dream. Izuku had been in the dream; half-human, and half-spider. He, himself, had been caught in a giant spider-web while completely nude. This explained why he was so frustrated with his eight-legged comrade to begin with.

Izuku's human half was like when he had been a villain; red eyes, and sharp features. Katsuki shivered. The bottom half of wasn't the fuzzy, tarantula body, but more of a garden spider's body. It was yellow-green with black tiger stripes, and long, slender, black legs.

The damn Izuku-demon had been muttering sexual-innuendos in his ear, and scraping his fangs along the rim of his ear. It gave Katsuki goosebumps just thinking about it. The dream had almost gotten steamier when he felt the sun's morning rays tickling his face.

After cooling off for a bit in his room, Katsuki headed for the kitchen. There was no sign of Izuku anywhere. He assumed the damned spider was hiding somewhere. He decided to make breakfast before he'd look for Izuku.

Katsuki didn't have to wait long. Izuku made his appearance when the smell of bacon wafted through the apartment. He had climbed to the top of the table, and waited patiently.

A strip of bacon landed in front of Izuku. He immediately started eating it like a ravenous dog.

"What? No 'thank you, Kacchan?" Katsuki teased. "Such a rude spider."

Izuku pointedly ignored Katsuki in favor of finishing his meal off.

After breakfast, Katsuki dressed for work, and lifted Izuku onto his shoulder. "Hopefully, they found some information from Dobutsu."

When they walked outside, Izuku noticed a pet carrier by Katsuki's neighbor's door. Something white fidgeted within it. Izuku's senses tingled; as if telling him there was something familiar in that carrier, the scent told him it was a rabbit. As they moved away, he lost sight of the white creature.

s s s

Fourth period was Katsuki's break, and he couldn't be more grateful to get away from the eager-to-learn lunatics. However, his break wasn't much for relaxation either, thanks to being selected as the creepy-crawler's caretaker.

"Well?" Katsuki growled.

Everyone was looking at the Deku-Spider sitting at the top of Katsuki's head, and it wasn't helping the blond's temperament.

"I'm sorry, Bakugou, my boy," Toshinori said calmly, trying to ignore the cute picture in front of him. "He won't tell us anything. All he does is laugh when we mention Izuku."

"What about the other animals?" Katsuki asked. "Have they been turned back into humans?"

Aizawa responded this time. "Most of the bigger ones have, yes. However, the smaller ones haven't shown any signs of changing back."

Well, this was discerning. Izuku sighed, which sounded like a soft whine.

It didn't go unnoticed by the younger blond, and he reached above his head to stroke Izuku's back comfortingly.

Izuku mewled, and arched his back with delight.

Toshinori chuckled as he plucked Izuku from Katsuki's head. "You two seem to be getting alone well."

"Not really," Katsuki muttered irritably. "He's been sulky all day."

Izuku gave a tiny, dramatic wail, holding his appendages out to Toshinori's face.

The older man grinned broadly, amusement written all over his face. "Come on, Katsuki. He's cute for a tarantula." His grin softened at his successor-turned-spider. "I wouldn't mind having him back to normal though."

Katsuki felt his chest tighten painfully. When had Izuku and Toshinori been so close? It...pissed him off!

Aizawa walked over to the older man, and leaned in very close to Toshinori. "I think you're making someone jealous," he whispered into Toshinori's ear. "His face is so red." He chuckled as they both turned to look at the younger blond.

"What?!" Katsuki barked. "Give me my spider back!"

Deku-Spider didn't wait to be handed over, and leaped to the table to stand before Katsuki. He looked up at his childhood friend with curious eyes.

"Don't look at me like that. You're being held to much. You're going to be spoiled!" Katsuki placed his hand over Izuku's body, as if trying to give the small frame a full body stroke, but his hand wasn't moving.

Izuku peeked out from under Katsuki's index finger, and thumb. It was warm there, so he didn't really put up much of a fuss.

At the end of the day, Izuku found himself back at the top of Katsuki's head, and getting a free ride back to the blond's apartment. When they reached the front door, he noted the pet carrier from next door was empty. Izuku didn't think much on it as they entered the apartment.

It was the same routine, except Katsuki actually took the time to move Izuku to a safe place before removing his shirt. He even went as far as to pick up the dirty one from yesterday, and threw them into the hamper in the bathroom.

Izuku felt strangely sluggish as he followed the blond around the apartment. They bathed quietly together, had dinner together (which was an egg roll cut in half for him), and went to bed together. The soft pillow was like heaven for Izuku.

Katsuki didn't fall asleep right away this time. He laid on his side facing Izuku, his hand curled around the spider's exhausted frame. "I'm sorry, Deku. I know you're more tired than usual, but I'm going to try, and take better care of you until you're back to normal." He stroked the pad of thumb over Izuku's back, and pulled him close.

The intimate moment startled Izuku, but he didn't move away. He felt soft, warm lips against the top of his head, and whimpered softly. He would give anything to return that kiss.

s s s

Katsuki's cell phone was ringing obnoxiously loud into his ear. He had forgotten that he placed it under his pillow last night. He scrambled under the pillow with his hand, looking for it. When he found it, he pulled it into view. It read 'Toshinori', followed by 6 a.m. "What the hell does he want? It's the weekend!" He answered it begrudgingly. "What?" He growled.

Toshinori ignored his former student's blunt tone as he responded enthusiastically. "All the small animals have turned back into humans! How about Midoriya? Is he back to normal?"

Katsuki's eyes widened as he pulled the phone away from his ear to look over his shoulder. He had felt it before seeing Izuku's human body pressed flushed up against his back...naked! He dropped his phone into the sheets, and kicked the other man out of his bed, a bright red flush on his face. "You fucking bastard! Why the hell are you sleeping in my bed naked?!"

Hearing the younger blond on the other end of the line told Toshinori that Izuku was definitely back to normal. There was a quick succession of objects crashing, and Izuku screaming for Katsuki to 'stop, and calm down.'

The older man chuckled as he hung the phone up, and turned to his two other colleagues. "Well, our Deku is back, and Bakugou is as loud as ever."
