I was reincarnated as a Slime?!

by LittleFox0807

Summary:

Izuku just knew when he woke up that today was going to be a terrible day and he was right, it probably started when the teacher revealed he wanted to go to U.A or when Bakugou told him to go commit suicide, all he knew is that after that terrible day it couldnt get any worse...could it?

apparently yes….

Chapter 1: reeincarnation

Izuku just knew when he woke up that today was going to be a terrible day and he was right, it probably started when the teacher revealed he wanted to go to U.A or when Bakugou told him to go commit suicide, all he knew is that after that terrible day it couldnt get any worse...could it?

apparently yes….

every step made his wet notebook flap and wobble against his arm

“does he really plan on going to U.A? he is going to die in the entrance exams!”

he doesn't really mind...he is too tired to mind

“You don't stand a chance without a quirk DEKU!”
“I'm sorry Izuku, I wish things were different!”

today had been hard...then again his whole life was hard

“ you think they would let in someone like YOU when they could have someone like ME?”
“how pathetic…”

it's fine really… he was used to it

“You know if you really wanna be a hero that badly there actually might be another way”

he just needed to keep going long enough to make it to U.A…

“Just pray that you’ll be born with a quirk in your next life…”

yeah...it wasn't that bad..

“And take a swan dive off the roof of the building!”

and if it was then that just means there's a chance for a better tomorrow…

“You’ll make a perfect skinsuit for me to hide in, kid!”

huh? what 's happening…

“It’ll only hurt for a minute, you’ll feel better soon!”

i-i can't breathe… it's hot…

REQUEST CONFIRMED: Acquisition of the Skill: Heat resistance is SUCCESSFUL

my body's weak… I think i´m dying! n-no i still haven't made it to U.A
all this slime is choking me...he could´ve been a great hero if he wanted to!

REQUEST CONFIRMED: Slime Body, acquired

somebody...help...me..

“HAVE NO FEAR BECAUSE I AM HERE-”

Is that who I think it is? everything hurts...help me-

“AH MY APOLOGIES YOUNG MAN!”

REQUEST CONFIRMED: pain nullification acquired

“HAVE YOU SEEN A VILLAIN NEARBY?”

i can't breathe...that's him, that's All Might. Why isn't he helping me?

REQUEST CONFIRMED: Creating a body that does not require breathing, SUCCESSFUL

“No sir Not at AlL BuT i HeaRd A NoiSE OVer TheRE”

i'm so cold...why is he not helping me…

Cold Resistance Acquisition, SUCCESSFUL. A Team Up Of Both Heat Resistance And Cold Resistance Has Resulted In A New SKILL: Thermal Fluctuation Resistance.

“THANK YOU FOR YOUR HELP CITIZEN! STAY SAFE”

I just wish… I had been able to help someone, to be a real hero… ha… I wish… I could have some cool powers in my next life… whatever I can get… haha… here’s hoping Kaachan was right…

CONFIRMING . . . Best Possible Response to Request: Acquisition Of UNIQUE SKILL: Predator, SUCCESSFUL. Future Prediction: Acquisition Of All SKILLS Necessary.

Maybe if I… I really was an idiot, I didn’t do anything to even be a hero. I should’ve studied more, should have devoted more time to learning all I could…

EXTRA SKILL Acquired: Sage. Continuing . . . Sage Will Transform Into The UNIQUE SKILL: Great Sage. SUCCESSFUL.

I’m so tired… I’m tired of fighting back against everyone… I’m tired of everything… I’m tired of being weak, of being hurt, of being useless, of being powerless…

“HEH for A HeRo hE iS prETty DumB”

just shut up...and let me sleep...maybe in my next life i can be a hero…..yeah that would be nice...

Chapter 2: new beginnings

Notes:

please let me know what do you think and what I can improve...I hope I can finish this fic...

thoughts: 'I am thinking'
speak: "I am speaking"
great sage: THIS IS GREAT SAGE (but dark)

Also I gave great sage the nickname Idaina because Apparently great sage in Japanese is Idaina Kenja let me know if I should change it though...

‘everything’s dark… I can't see anything where am I? what happened...was there someone making fun of me? something about a sage or was it a great sage?’ 

with that i regained consciousness...and found that I couldn't see anything…

’it's ok really there is no time to panic’...

that's when I realized that I can't seem to move my arm to touch my head and even worse i can't feel it! ‘oknowitstimetopanicwhatdoidothereissomethingcompletlywrongwhatjustappened..ok breathe calm down let’s see what i remember...i am izuku midoriya 15 years old i was walking home when the sludge villlain attacked me…..i am dead arent i...ok so i am dead, i can't see or move but i seem to be alive? maybe in a coma? no because i distinctly remember dying..’ 

just when i was about to spiral in another fit i felt something and all my senses focused on that sensation, with a horizontal stroke on my belly (?) I felt what appears to be something akin to grass. After awhile i decided to move and i did…

‘ok this is starting to get weirder by the second...looks like i can try to move though..’

with what i felt was bouncing i felt myself land on a patch of grass…

‘so i don't have arms or legs...or a body but i can move and feel things although i seem to not have smell, hearing or sight maybe i have taste? but where would my mouth be…’

<Activate unite skill “PREDATOR”  ?  < YES/ NO >

suddenly there was a voice in the back of my head…

‘what was that...unique skill predator? is that my quirk? i think i heard that voice when i was with the slime villain...something about...giving..me...a….slime body! oh no no no did...i reincarnate as a slime?! ok breathe um…NO?’

i needed to experiment a bit first... but just that seemed to evaporate the grass inside my body. And then i waited for the voice to continue explaining or anything but it seemed to be gone so i just continued to evaporate the grass inside my body and doing various experiments, during that time i discovered i can’t sleep, i seem to not get hungry and i couldn’t see where i was no matter how hard i tried...my theory is that i am in some kind of cave? not sure

‘where does all of the food that i eat go? I seem to have no need to eat yet i can ‘evaporate it’ but i doesn’t do anything other than just stay there…’

< Solution. It is stored in the stomach associated with UNIQUE SKILL PREDATOR. At this moment less than 1% is occupied >

what-- a response! But since when have I been using that skill? i selected [ NO ] after all, maybe to test later but nothing seemed to be working to activate it…

< Solution. Unique skill PREDATOR has not been activated. Substances entering into the body are automatically stored. This function is modifiable >

huh the responses are becoming better now…

‘So about the skill, what happens if i use it?’

<SOLUTION. The effects of Unique Skill『Predator』are…

Predation: To absorb the target into the body. However, if the target is conscious, the success rate greatly decreases. The affected targets include organic matter, inorganic matter, skills, and magic.

Analysis: The absorbed target is studied and analyzed. Craftable items can then be produced. Should many items gather, a duplicate can be produced. In the case of successful skill or magic analysis, the same technique can be acquired.

Stomach: The target can be stored. Items produced can also be stored. There is no storage time limit.

Mimicry: Replicate the target’s appearance. The skills and abilities used by the target can also be used. However, this depends on the successful analysis and acquisition of relative information regarding the target.

Isolation: Materials harmful or unnecessary for analysis can also be stored. They will be used to replace magic energy.

These five points are your power >

‘uh...what?! t-this is so powerful! i can just absorb something and obtain not only its appearance but also its powers?! talk about overpowered...that means i can continue my dream of becoming a hero! i have never felt so excited! wait before i can continue to freak out...the voice i have been hearing... is someone there?’

< Solution. This is an effect of the Unique Skill『Great Sage』. For the sake of quickly utilizing your skills, a response function has been added >

‘thatsreallyinterestingalthoughiwonderabouttheapplicationsforsuchpowermaybesomekindofguideforbegginersorasorterandhelperforthisnewworldmuttermuttermuttermutter….no! concentrate ahem could you show me my status kinda like those games?’

‘ok so i am no longer human but a slime good to know...i still can’t seem to believe i have all of these skills...why are slimes even considered weak with all of these bonus...anywho now that i know a little bit more i can continue to experiment even more like..um do you know how many days have passed?’

< 90 days 4 hours 20 minutes and 60 seconds >

I spent a good time asking questions...for example it was confirmed I don't need sleep, water or food since I just absorb magicule molecules, something that exists in this world as some sort of building block for every living creature. I continued to absorb the grass and now I even began to transform it into a healing potion inside my body! apparently it was a rare type of grass that contained a lot of magicules oops...i saved a bit though to make sure i wasn’t taking too much only what is necessary in case i get hurt i also learned a bit more about great sage which is nice

 < Unique Skill『Great Sage』 has the following effects…

Thought Acceleration: Raise the speed of thought processing by a thousand times.

Analysis and Judgment: Ability to analyze and make judgments regarding a target.

Parallel Processing: Ability to detach thoughts and analysis of phenomenon.

Chant Annulment: When using magic, there’s no need to chant.

All of Creation: Ability to comprehend all non-concealed phenomenon in this world.

These five are your abilities. >

that was extremely helpful and of course overpowered being able to analyse, think and judge faster than i could in my previous life was a blessing and a gift and i am becoming more and more curious about this world although it seems to know more i have to leave wherever i am at the moment...and if thought acceleration wasn't fast enough i found that i could combine great sage’s though acceleration with predator’s though acceleration and made it even faster at first analyses took 5 minutes it now takes 1 which makes it a bit scary...while thinking and conversing with Idaina (i nickname Great sage to Idaina and it stuck) i felt heavy and light at the same time….

‘It looks like I fell into water...oh god how do i swim? umm what if i absorb the water and expel it to propel myself forward? worth a shot…’

i predated enough water to fill a bit of my body and then let it go with enough pressure to be sent flying towards nowhere. That's when I heard it…

<  Skill『Hydraulic Propulsion』has been acquired. >

i didn't have enough time to process it though...and i went hurling towards a rocky surface taking some damage and immediately got it healed with self-regeneration 

‘umm wonder how much damage could self regeneration heal ...are the potions really neccesarybecauseifsomuttermuttermuttermutter…’

( Can you hear me little one? )

 

‘what was that?!’

Chapter 3: Storm Dragon Veldora

‘i definitely heard a voice...well more like being aware of it?’

( oi! you can hear me can’t you? Responding would be good! )  

‘umm how do i respond? maybe trying to project it in my head?’

( i can hear you! hey can you hear me? ) 

( i can certainly hear you little one...it has been awhile since someone has visited me so forgive me if i seemed rude )

( no problem! i just can’t see or hear anything so if you tried talking to me before with no avail that was more of my fault than yours…)

( Interesting. Slime species are typically thoughtless creatures that only [Absorb], [Dissolve], and [Regenerate]. I have yet to behold one leaving their territory When a slime suddenly rammed my body, I naturally found it rather bizarre. At an exceptionally high speed, at that. What are You? A named monster? A unique monster? )

( i apologize if i have caused you any inconvenience sir...but i truly do noy understand any of what you said i have been only born 90 days ago… )

(It matters not...if you wish to see then i could be of use There exists a [Magic Perception] skill. Can you use it?)

(No, I cannot. What type of skill is it?)

(You perceive the surrounding magical energy. It’s not a major skill, and acquiring the skill is rather simple.)

(I see! If I were to acquire it, would I be able to see?)

(That is the idea. The world is covered in magical energy. There is a difference in concentration. And, light and dark possess a wave like property, did you know?)

(Yeah, light waves and dark waves, right?)

(You know well, is that knowledge from the other world? Well, it is so. But observing these fluctuations, you can calculate the appearance of the surrounding. Simply, right?)

(Please teach me!)

(Nay, fret not; it is truly simple. First, try to move the magical energy inside your body.)

This, I somehow understand. I think I can use the same principle as moving through the water.

(Like this?)

While enclosing it in my body, I verify movement of magical energy.

(Ay. Though you said otherwise, you seem quiet apt at this. In this case, the energy that moves within you and that which is beside you–do you feel the difference?)

This is actually pretty simple.

 

(Since you understand that much, the rest is simple. Feel the movement of magical energy outside of yourself.)

That’s what I don’t understand, though.

Anyways, as instructed, I tried to feel it.

I do feel it swaying. Back and forth, back and forth…

Right! Let’s activate [Great Sage]!

＜＜Verified. Extra skill [Magic Perception]… has been succesfully acquired＞＞

＜＜Will you use extra skill [Magic Perception]? [YES]/[NO]＞＞

Eh?

Did I really just acquire it that easily?

Well yeah, of course, [YES].

As expected, [Great Sage] is reliable as always!

The moment I activated the extra skill [Magic Perception] , my mind was filled with information.

Little by little, magical energy moving along–waves of light and darkness.

Having grasped all of the incoming information, I convert it into one I can understand.

And so, I can now see 360 degrees around me, without a single blindspot.

A boulder’s shadow, the scenery 100 meters away: if I direct my consciousness there, I can see it.

And so…

＜＜Linking extra skill [Magical Perception] and unique skill [Great Sage]… complete＞＞

My field of vision cleared up.

That I wasn’t able to do this until now is strange in itself, this is an obvious form of “vision”.

[Great Sage] just might be op.

(Well… I somehow seem to have managed it. Thank you very much!)

When I said that, I finally beheld “that.”

… a real dragon.

Gleaming like black steel, flexible and durable, like the scales of a fish….

The visage of an evil dragon…ok just calm down...he was nice and he won't hurt you…

(t-thank you so much!) I tried to bow but it looked weird on my slime form..

(So… what shall you do now?)

(i-im not really sure...maybe explore this new world and live my life to the fullest)

(very well…)

 

w-wait...why does he sound so disappointed?!

(u-um if you want we can be friends?)

(Wha, what did you say? For the feared Storm Dragon Veldora to become f-f-friends with someone of s-s-slime’s social standing?!)

(i-im sorry its okay if you hate it understa-)

(Stupid! You! Nobody said anything about hating!)

(Eh, then? Umm… what will you do?)

(… let’s see… well, if you insist… I can consider…)

(I insist! i-i mean please! i mean If you hate, the deals off. No second chances!!!)

oh my god i shouted at a dragon he is going to kill me…

(Cho…! Then I have no choice! I’ll become your friend! Show me your gratitude!)

oh thank god…

(then I will be in your care!)

(Ay! … oh, and let me grant you a name. You also give me one!)

(Huh? Why? So suddenly?)

(To etch into our souls that we are equals. As humans call it, Family Name type of thing. The one I grant you will bestow upon you “Diving Protection”. You still lack a name, so you shall become a named monster now!)

So, I have to come up with a Family Name (one for common use), huh?

I’m not really good at this stuff…

(Since you are called the Storm Dragon, how about simply “Tempest”?)

(It’s decided! What a wonderful name!)

He liked it!?

(From now on, I am Veldora Tempest. And you…

Shall be called “Rimuru,” Rimuru Tempest shall be thine name!!!)

And that name was etched into my soul

From what I can see and feel, I don’t feel any different.

But somewhere deep in my soul, I felt something change.

That would be something to mention to Veldora, wouldn’t it?

And so, I have become friends (or would it be more appropriate to call this soul-mates?) with him.

(Oh, and before I go, I wanted to ask. Is there nothing you can do about that seal?)

(Not with my power. If it were a unique skill like that of a hero, then it could perhaps be possible…)

(You do not possess any unique skills?)

(I do. But from the moment the seal was placed, I could no longer use any. I barely managed retaining my telepathy…)

At the moment, the hero’s unique skill [Endless Prison] prison seals the target in endless time and imaginary space; an unpleasant skill that does not permit interference from here.

Though it does seem strange that the only thing he can do is to communicate telepathically…

It’s not like the skill weakens with time, after all.

Being able to even recognize the present and converse with other creatures all seem like example of interference. What’s unusual is Veldora himself here…

Of course, both us noticed this.

(Alright. There’s something I want to try…)

As I said that, I touched Veldora.

And,

＜＜Attempting to predate unique skill [Endless Prison] via unique skill [Predation]… failure＞＞

As expected, a hero’s seal is not going to be this easy.

For but a second, interference with the hero’s skill released a blinding light, but then it returned to normal.

Seems like for a brief moment, a seam opened in this endless prison. But it quickly restored itself.

And anyways, “Since it’s also a unique skill, something’ll happen” type of thing will only lead to trouble.

Isn’t there anything I can do?

What to do…

＜＜Solution. Unique skill [Endless Prison] has been partly analyzed. I shall present the escape method.

It is impossible for flesh to escape. Physical damage wise, the chance of destroying the prison is 0%.

With regards to the imaginary space escape method–the analysis proved impossible.

Analysis in identical situation–imprisonment in an [Endless Prison] is necessary for analysis. Therefore, currently this is impossible.

The chance of releasing a spiritual body is 1%.

Should one prepare a host for the spirit ahead of time, and move there in the process, the success rate increases to 3%.

At the moment, this process is similar to reincarnation. Should the affinity with the host be poor, memories and skills will all be reset.

End of the report on escape methods＞＞

…Fumu.

The chances are far too low.

Doesn’t look more than flimsy film, this [Endless Prison] skill.

But for it to be impervious to physical damage….

There must be some weakness to this absolute defense.

(Did hero take any damage? Any wounds or something?)

(Well asked! Our blows were well watched, and I have landed a few direct hits! But, there was no effect. “Death Calling Winds”, “Black Lighting”, and even “Storm of Destruction”. All are skills that cannot be evaded, and yet no effect! I gave up! It was laughable!!!)

And all other similar babble would end in Veldora’s loud laughter.

Unique skill [Endless Prison] was definitely used to cover her body, if all outside interference is negated, no shield is necessary.

What a useful skill!

Unique skill [Certain Severance]

Unique skill [Endless Prison]

If you combine these two, wouldn’t you be essentially invincible?

Definitely don’t want to meet her…

She should have passed away by now, so should be okay.

Without a question, she belonged in the strongest class.

Anyways.

The escape to host method, huh?

To escape, a host to transfer the soul to seems to be necessary. It is also possible to escape in a spiritual body, but the success chance is low.)

Don’t really see the reason to mention the percentages.

If Veldora’s desire to escape decreases so could the chances…

(Mu? There was an escape method! Honestly, after some 100 years my magical energy hit empty! Probably since I didn’t stop the flow of magical energy…)

(I see… that would be the reason why the magical energy concentration around here is so high.)

(Ay. The truly strong monsters also avoid this area. Grass also hardly grows underground. Only some rare vegetation inhabits these caves!)

Ah.

I remembered about the Hipokte Grass.

In this case, it’s a pretty valuable medicine…

(Well… since that’s the case, will you attempt to escape? If you had a place to transfer to, the chances would be higher… and also, what’s considered a good host?)

(… Unfortunately, even if I detach my spirit, to gather the magical energy into a single core is rather difficult…By opening a seam in the seal, that’s how this will succeed. And a host, huh. That is, preparing a new core and moving there… reincarnation!)

This guy!

I thought that he might be slightly slow-witted, but he perfectly understood all of it.

How wondrous… he reached the same conclusion as the [Great Sage].

(That’s the thing. So, if there’s something I can prepare, should I go look for it?)

(Hmm. The thing is, I don’t really need a core… oh, and keep this secret? I am a “being perfect as one”. Especially durable.I am a spiritual life-form, and thus have no attachment to this body. I merely responded to the wishes of religions and the like when forming it.)

Again with that incomprehensible stuff. And so we spoke until I understood. The result. Gather the magical energy with one’s mind, and then form the flesh.At the moment, the flesh being bound is beyond question, but the mind also cannot affect the surrounding magical energy. That’s the situation.So I asked if he could leave as a spirit.

(That is impossible. I would require an offering.)

Is what he said.

If he were to leave in this way, he would scatter with the magical energy and cease to exist.

And, somewhere else, another “Storm Dragon” would be born.

That is one means of escape, but if there’s no meaning to it if it means becoming a different person.

I’m at a loss.

Wouldn’t eating Veldora with [Predator] be a better alternative?

Place him into the [Predator]’s stomach, analyze at depth the [Endless Prison]’s effects and eliminate just them… could this work?

＜＜Solution. Target: Veldora can be absorbed with the unique skill [Predator]＞＞

It’s possible, huh…

If I explain it, will he consent?

If this goes on, after a hundred years of isolation, only to disappear would be his fate.

And so, I explained to Veldora the [Predator] ability and how I thought to use it.

This would be impossible, however, without the [Great Sage] ability correction.

(Kuahahahaha! Interesting!!! Of course I’ll try it. To you, I’ll entrust my everything!)

(Should you be trusting me so easily?)

(Of course! Rather than waiting for you to come back here, tearing [Endless Prison] asunder and leaving together inside of you sound so much more amusing!)

I see.

Not alone. Together.

Isn’t it fine?

With [Great Sage] and [Predator], I’ll continue analysis and seek to free Veldora from his imprisonment.

And in this stomach there is no fear of scattering and disappearing.

I think we can do this.

(Alright. I’ll eat you now, try to break out of [Endless Prison], okay?)

(Kukuku! Leave it to me! Don’t wait, I’ll pause it for you!!!)

Okay!

I made my decision.

I touch Veldora, and begin Predation.

In a second, the giant Veldora disappeared from my view.

That was too quick.

He was speaking up until a second ago.

Having disappeared so suddenly… makes me lonely.

The skill highly depends on the target’s resistance to being absorbed, but as expected of Velodra–no resistance what so ever.

Must say, I’m surprised I could absorb that huge body.

It seems that at the moment, my stomach is 25% occupied…

Just how big of a space have I got in there?

And…

＜＜Will you begin analysis of the unique skill [Endless Prison]? [YES]/[NO]?＞＞

I beg you!

As if in a prayer, I accepted .
