You probably didn't need those organs - BnHA quest

[X] *Awaken plays in the background*

"A-are you sure this is safe?

"Aw, you don't have to worry about me, De-kun! All my important parts are up here, anyway."

"That… wasn't what I meant, Kaede."

Izuku hadn't been very enthusiastic about being eaten, for some reason, so you'd offered to make your stomach a bit less cramped by moving some bones out of the way. You'd disconnected your lower half again, this time with crude circulatory and respiratory systems attached, in order to keep it alive for however long this would take. After that, he started making excuses about accidentally damaging your other internal organs, so you'd messily relocated them to a large growth above your shoulders. Thank god for plastic sheeting, because your mom would have killed you if she'd had to replace the carpet again. That said, she might kill you later for emptying the fridge for the third time this week, but oh well.

"De-kun, do you want these upgrades or not?"

"Yes! Of course - it's just… It's kind of scary to, er, be eaten alive, you know?"

"No, not really."

He deflated at your uncomprehending tone, and resigned himself to his fate as your first test subject. Okay, it sounds bad, but is there really any other way to put it? Wait, no time to waste with that - lets see what organs Izuku can do without…

Appendix, that's a good place to start; you broke it down into parts his body could reabsorb. Oh dear, that appeared to cause some internal bleeding. Shit. You [pushed] as much coagulants as it was safe to into the area and hoped for the best.

Now that there was a bit more space inside, you set about getting his lungs to grow; you figured that if he received more oxygen, his body wouldn't produce so much lactic acid. You couldn't help but feel smug about your quirk again - no acid buildups for you when you could manually neutralise it. Anyway, producing this result in something not fully 'you' was an arduous process: you had to first copy the parts of him that contained the 'plans' for how his lungs should be built, then edit said plans so that they'd think that his lungs should take up more space than they were supposed to, then test the plans out on your own [focused] lungs to make sure that they would grow in a way that wouldn't kill him, which took a surprisingly long time. Humans were so… breakable. All before destroying his copy of the original plans and [pushing] the improved ones into place.

Countless spiders had died for you to gain that level of accuracy, but it would be worth it to make De-kun happy. Speaking of...

"Izuku, you doing okay?"

No response, he was sleeping. Might as well edit a bit more.

While you were at it, you redid the 'plans' for his intestines too - they already wasted so much space that it probably wouldn't matter if they didn't grow to match his new proportions...

Hmm. Was he using that spleen? You decided to leave it, just to be safe, but two kidneys? That was just pointless - you broke one down before you could stop yourself ...aaand there was the internal bleeding again. Luckily, your quirk made topping up his blood supply relatively simple.

Although you wanted to give him an amazing stomach like your own, it simply wouldn't work without your quirk to support it, so you had to settle for making him as much like his favourite hero as possible. Now, he's going to need to be a bit bulkier if he would be fighting villains, so you gave him the same treatment you'd given yourself when you realised that you weren't growing as much as all the other children. Repeating the same process you had for the changes to his lungs, you made sure that his liver would synthesize more growth hormones than usual, which would, in theory, slow his rate of lipogenesis as well as help him slowly become… er, whatever the term for 'not a scrawny midget' was. Sure, there could be side effects later on, as he didn't have your quirk to help prevent them, but you could fix that. Probably.

You let Izuku out. He didn't wake up for a while, in which time you managed to pull your body back together and comfort your other, smaller friends.

"Owww… Kaede… what did you do?"

You pushed a plate of food over to him - mostly kale and iron supplements, but it would help his body make up for the blood he lost. And again with the guilt…

"Do you want the specifics, or the summarised version?"

"...mmphh…"

Summary it is.

"Well, the good news is, you're never going to have to deal with appendicitis! That, and you're going to be expecting some growth spurts pretty soon, so I hope you like clothes shopping."

"...yay?"

You kept an eye on Izuku for the next few months, but nothing major went wrong, which was unusual considering your track record. Maybe the universe would simply not allow someone so adorable to die? You should test tha - NO nope no no not testing that. Shut up, brain.

Despite the unlikelihood of success, Izuku began getting taller; not to an unnatural degree, but just enough so that he didn't seem like such an easy target for the other students any more.

Over the course of the next year, you practiced creating organisms by combining stem cells you'd collected, striving for something flight capable. You didn't get very far on that; while you understood the theory behind the structure of bird bones, you simply couldn't get it to come out right without some kind of reference. On the plus side, you made a new friend.

You'd decided to mess around with the huntsman spider cells, initially to see what went wrong with your flawless plan to create a legion of acid spitting spiders, when you realised how many legs they had.

You lived your life firmly adhering to the philosophy that the more limbs something has, the better the hugs, and therefore the more you should risk life and limb in order to obtain said hugs. While your girls had spiders beat with their sheer number of legs, spiders made up for it in length that centipedes' ittle bitty needle feet just couldn't match. Also, spider legs were fluffy, automatically making them the best thing ever.

And so, what started as an attempt to grow a spider big enough for hugging gradually snowballed into Bael, the giant fluffball / pillow / dog. Bael was like a dog in the way that they liked to bring you things. Like dead animals. Bael was a good boy.

It turned out that insects can physically be a lot bigger than their maximum size without any major overhauls to their anatomy; they didn't naturally because it was incredibly inefficient for avoiding being eaten, or consuming enough food to live. As your new friend would not be having any problems with either of the above while you were still alive, you could increase their size to just under double that of a normal one. Swap the reproductive organs and the functionally useless spinnerets for an enlarged respiratory system, and you could go even bigger.

The finished creature would grow to own a roughly eighty centimetre leg span, but for the time being little Bael could still fit in your hand. If they squashed their legs up a bit.

He got along well with De-kun, who was always so excited to find the spider hiding in his hair or schoolbag.

The two of you had begun preparation for your final exams when something vaguely interesting occurred.

Although Bakugo, as well as the majority of the school body, ignored you and Izuku almost entirely, your not-so-tiny-anymore friend's determination to get into UA had sent him over the edge. Thankfully, you had been there to interrupt Bakugo's threats through the means of a centipede to the face.

Hmm, blondie has a debilitating fear of venomous bugs on his face, who could have guessed?

Daigankai was fine, but you and De-kun had missed the last bus, and so had to walk back, not that you minded the opportunity to talk. The scores UA required for entry were worryingly high, so the two of you had spent more time studying rather than actually interacting lately. Well, you've been studying, and Izuku has been attempting to tutor you; you may or may not have tuned out too many classes in favour of playing with your friends.

Now that you think about it, why did they set the bar so high in the first place? Surely your failure to solve quadratic equations was unrelated to fighting villains?

"Kaede, will Bakugo be alright after that? I know he can be a bit… abrasive, but I still…"

"Nah, he'll be fine - the venom's not lethal to humans. He might want to get that bite checked out though… I think she may have started trying to eat him, seeing as they're all so used to being able to snack on me."

He shuddered at that. Ah, he must be cold.

The two of you continued to walk, chatting about something inane to fill the time, until you heard something... strange. Like a surge of water below the ground. But it's not been raining, so it can't be from the drains…

"De-kun -" You interrupted his analysis of the latest licensed heroes. This could be dangerous for him.

"There's something weird underground…"

Your ears twitched, were those footsteps, too? The rushing sound grew louder, passing beneath you and moving ahead. It seemed to slow as it passed beneath the shadow of the overpass before you - was that a manhole cover?

"It's going to come out over there, we should m-"

You paused, the footsteps were getting louder, as if whoever was pursuing the strange mass was getting closer. The liquid thing had taken too long to make up it's mind on surfacing, and would be intercepted at this rate. It could be dangerous, but whatever happened next would almost certainly be interesting to watch.

You turned to Izuku, who was panicking at your uncharacteristic silence, and grinned.

"Want to watch the fight?"

AN: Soon...

Just going to take this opportunity to awkwardly mention how happy all your responses make me. It's on the same level as somebody randomly giving me a box of cute animals. But I also find you all terrifying, so more like somebody giving me a box of alligators? I mean, they're adorable, but now I have no hands.

I realise my metaphor is wearing a bit thin here, so thank you and I'm off to be embarrassed in a corner now.
