AN: My Hero Academia + That time I got reincarnated as a Slime + Overlord (Certain interactions)

Izuku Harem

Chapter 1

He felt odd. His eyes wouldn't open and he couldn't feel his arms of legs. "My body, something is wrong with me; wait I can't see anything!" he exclaimed in terror. "What's happening this can't be happening to me..." he could make out a blur of something in front of him. The shape being that of something extremely common. "Is that, a rock?" he moved forward. He did have sensation after all. "Wait a second, where am I?" he moved forward a bit more until he was on top of something. "Is this a..." his voice didn't work so he couldn't talk out loud. "Plant?" said plant was sucked into his body and dissolved after a few seconds. "This feeling." he couldn't describe it, but it felt oddly good. "Wait a second, humans can't dissolve plants; well someone with a certain quirk might be able to, but I can't..." he paused for a few moments. "I couldn't before." a sudden question came to mind. "What happened to me?" The teen tried to remember. "I met the Pussycats and Kota again, headed back to the dorms with the others, and there was someone at my door; we didn't know who it was..." He stopped moving. "He stabbed me in the stomach...and chest." the harsh realization had come much to quick. Izuku Midoriya had been murdered; he'd been murdered.

"If I died then why am I here? Why do I feel alive?" such a question that he would have to figure out on his own or with help from someone smarter than him. There had to be a reason for this. Moving forward a bit more, he began to notice something off about his body. "I feel kind of, bouncy." the teen said before he began to bounce forward. "Yep, bouncy with some elasticity." he stopped. "As for my exterior, it's very..." he began to try and process the answer that he sadly knew was right. "I'm a slime." he stated. Indeed, Izuku Midoriya had turned into a small dark green slime. "Oh god, why a slime of all things?!" he exclaimed. "First I get stabbed to death and then I get reincarnated as a slime, the universe hates me doesn't it?" despite his lamenting, he continued onward.

Two Weeks Later - Cave

Izuku didn't know how long it had been since he woke up as a slime, but he was sure that it had been a pretty long time. In that time he'd learned how useful his new body was. He didn't need to eat or sleep. "And there goes another flower." And, he'd been consuming all the flowers that he came across for a single reason. He was utterly bored, and alone. He could not find an exit. "Wait, where is all this stuff I'm eating going?" he paused. "I haven't used the bathroom in-"

'Answer' The sudden female voice made him jump. 'It is stored in the stomach of your unique skill: Predator.' the voice stated.

"Thank you for explaining that-wait a second, I heard your voice when I get stabbed."

'Answer, it is the effect of your unique skill, Great Sage, and now that your ability has been established you are capable of reacting much quickly.'

"Skill, my abilities right, but what is Predator?"

'It allows to ingest and analyze objects within your stomach; you can then acquire that object's skills.' The ability sounded just like All for One. 'Once the analysis is complete, you will be able to mimic that object as well.' just like All for One. 'The stomach stores objects you ingest, and can also isolate harmful objects that cannot be analyzed.' Alright, All for One couldn't do that.

"I have to admit that 'Predator' sounds like an amazing skill." he couldn't deny it. "Can you analyze the flowers that I've been eating." it took a few seconds for the analysis to complete, but when it did, Great Sage informed him of their uses. The Hipokute herbs were very valuable and grew in areas rich magicules. They were used to make salves and healing potions. The teen was also informed about what magicules were, and what they were; the building blocks of all life in magical beings including himself. "Great Sage, do I have any other unique skills?"

'Answer, yes your final unique skill is 'One for All'.' This wasn't what he wanted to hear. He died and took One for All with him. Granted, it wasn't on purpose but still.

"Maybe I'll find a way to use it if I ever get out of this cave; I'll put it to good use." he wouldn't give up on becoming a hero, no matter what world he was in or body he had.

A Week Later - Cave

Hipokute herbs and magistone ore; this had been his diet for the past week. He consumed every one he saw or could find. "Eat everything, and leave nothing; I have to store up on potions if I ever need to-" The teen fell into a lake, he hadn't paid enough attention to where he was going. "This is what I get for not paying attention to my surroundings." he couldn't swim up or at all. "Looks like slimes don't float; am I going to die again?" landing on the bottom, he 'sighed'. "I don't think I ever breathing in the first place, it explains why I'm not suffocating, but how am I going to get out of here?" - "I can't swim, but maybe I'll be able to propel myself!" the teen sucked in water and held it for a few moments before propelling himself forward up to the surface and riding the water like a speed boat.

'Skill: Water Pressure Propulsion acquired.'

"That's nice, but I'm going to fast!" he exclaimed. Moments later he was flying through the air. "Not good, not goo-" he smashed into what he thought was a very large rock. falling onto the ground, he got up almost as if he wasn't feeling any pain. "That wall, I hit it really hard, but I don't feel any pain.' he stated.

'Answer, because you have acquired the Pain Nullification skill, you will not fell pain; the physical damage you've taken is 10%. Special Skill Self-Regeneration has been activated.'

"I still take damage, but I don't feel pain; wish I had that when I was human." the damage to his head healed. "That was quick, but I need to be more careful." Izuku began to leave.

"Can you hear me small one?" the voice was loud and booming, it filled him with a sense of dread. "Can you hear me, small one?" the voice repeated.

"Yes, I can hear you, but I can't see you." he turned to the large opening in the wall, the inside was rich in large magistone ore.

"I see." the being narrowed his eyes at the slime for a few moments before making his decision. "Small one, I will give you sight."

"Sight, you can just up and give me the ability to see?!" the teen was excited.

"Correct, but there are conditions."

"What are they?"

"First, you must not fear me when you see me, and you must come back and talk to me." the being said. Silence reigned for a few seconds before Izuku spoke.

"Easy enough, but what's up with the second request?"

"You see, I was sealed here 300 years ago, and since then I've been unbearably alone and bored." he stated.

"300 years, I kind of want to know why you were sealed but..." Izuku found no real negatives to the being's deal. Maybe he would be able to learn something from the being about where he was, and what happened to him. "I feel like 300 years is long enough, so let's see you!"

"Very well. There is a skill called Magic Sense; can you use it?"

"No, this is the first I'm hearing of it." he stated. "I'm going to take a guess and say that it'll allow me to sense the magicles around me, right?"

"Correct."

"And if I can detect them then I'll be able to see."

"You catch on quick for a slime." he stated. "But, try anyway."

"I'll try." Izuku concentrated as best he could, with Great Sage doing its' job as a slight rainbow aura surrounded the slime until sight was finally gained. "I can finally see!" exclaimed in joy.

'Extra Skill: Magicles sense acquired.' Great Sage stated. 'Would you like to use it?'

"Yes!" the skill fully activated, and he could finally see clearly.

"Amazing, it all looks so amazing!" he exclaimed.

"Well, how is it?"

"It's beyond great." he turned to the being that had 'given' him sight. "Thank you..." In front of the dark green slime was a massive, intimidating dragon; this was who he'd been talking too this entire. His scales gleamed like black steel, flexible, and durable, like the scales of a fish. Silence reigned as Izuku stared at the beast in awe. "You're a dragon."

"And, you are a slime." he said leaning forward, the slim was already close enough. "Allow me to formally introduce myself, I am the only Storm Dragon Veldora."

"Storm Dragon?"

"I am one of the four true Dragons that exist in the world." the now named Veldora stated. He began to chuckle. only to burst out laughing causing the ground to shake. "You do remember our promise right?"

"O-of course, in fact I'd like to talk right now." The teen stated. This took the Storm Dragon by surprise.

"Hm, this is unusual." he said. "Slimes are normally low-ranked monsters that don't think, but you have self-awareness." he explained. "Are you Unique?"

"Define Unique."

"It refers to a being with extraordinary abilities."

"Well, I used to be human." This took the dragon by surprise. "But, I was killed, and the next thing I know, I wake up like this."

"In that case, you were reincarnated."

"Reincarnated, I think that I understand; it's pretty simple when you think about it."

"You catch on quick." he said once more.

"Well, I was a student when I was killed."

"How old are you?"

"Sixteen."

"You died young, shame."

"It's alright." He smiled or at least what was the equivalent to smiling since he was a Slime. "People from other worlds in general can get here?"

"Yes, we call the Otherworlders, and you are the first to be reincarnated."

"I would like to meet some of these Otherworlders, maybe I can find someone from my world." The thought of finding someone with a quirk, excited him.

"Oh, you're leaving already." the Dragon was actually pouting.

"Don't worry, I'll stay a bit longer."

"Please do!" Veldora really had been alone for a long time. "Stay as long as you want!"

'I swear...' he noticed the barrier that surrounded Veldora. "Veldora, you said that you were sealed 300 years ago, why?"

"I'm glad you asked." Veldora's story sounded as real as could be. Apparently, he accidently turned an entire town to ash, and how someone came to slay him. The Dragon underestimated his opponent before going all out, but he still lost. Then again he was facing a hero who was blessed with divine protection. Izuku held in the urge to laugh at the stereotypical fight, of course the hero was going to win. And, the hero was a human; it sounded like something off of a video game or comic book. The hero overpowered him with a unique skill, Absolute Severance, before sealing him with Unlimited Imprisonment.

"All those shiny crystals are part of the skill?"

"Correct, the hero called herself a 'Summon'." he said. Veldora proceeded to explain what a summon was, and needless to say Izuku was grateful to be reincarnated as a Slime. To be ripped from their home against their will, bound to someone you don't know, and then used as a weapon.

"That's beyond cruel." Izuku stated.

"I don't know how your world was, but survival of the fittest prevails in this world."

"I see..." he would experience this first hand. "So, you've been here in this cave ever since the hero sealed you?"

"Yes, and I've been so very bored." Again with the boredom.

'I can't say that I've never known loneliness...' He couldn't help, but pity the Dragon; there was one thing he could do for the beast. "Hey, Veldora, we should be friends!"

"What?! A mere Slime proposes friendship with me, the fearsome Storm Dragon!?" he exclaimed. For some reason, Izuku felt a sense of courage that he'd never felt before; he wasn't scared of the powerful Dragon.

"Yes, I do!" he exclaimed. "But, if you don't want to-"

"Fool! No one said I didn't want to!"

"Alright, then what do you say?"

"Well...if you insist...I guess that I'm willing to think about it."

'Is this what Shoto told me about? Tsundere?' he bounced forward. "Yes, I insist, and that settles it!" The teen said. "Unless you'd rather refuse, and I never come here again."

"Alright, I'll be your friend. You'd best be grateful!" Veldora said, he really wasn't going to let this chance slip by.

"Just try and be honest, it makes things easier for both of us." Izuku said putting out a 'hand'. "Now, it's nice to meet you!"

"Indeed." Hand and claw shook. Veldora the Storm Dragon, and Izuku Midoriya the Slime were now friends.
