Kirideku!!! Yay! (I'm such a multishipper)

Kirishima and Midoriya were out in the park, when they found a Dragon egg...

It was a beautiful day outside. Birds were singing in the trees, a light breeze making the branches sway and carrying their bird song. Flowers bloomed along the grass, adding a pop of color to the scenery. Few clouds floated in the sky, the sun shining on the earth gently. Kirishima and Midoriya were both content to sit in silence, holding hands as they took in the view.

Midoriya leaned over, resting his head on Kirishima's shoulder. Just in that moment, Kirishima noticed something in the corner of his eye. It looked like a scaly, silver egg, lying in a patch of flowers a small distance away from the bench the two boyfriends sat at. "Huh... hey Izu, look at that!" Kirishima said, pointing at the egg.

"What do you think it is..?" Midoriya questioned, and Kirishima shrugged, "Well, lets find out!" Kirishima stood up, and Midoriya followed, both curious about the egg.

Kirishima crouched down in front of it, placing him hand on the egg. "It looks like some sort of dragon egg..." Midoriya commented, looking over the red-head's shoulder. "Yeah, it does.. and it's really warm, too! Here, feel it!" Kirishima exclaimed, and placed Midoriya's hand on the egg. It was a pulsating sort of warmth, gentle and filled with life. Both of them easily figured, there was a baby in the egg. And at the same time, they both said, "We should take care of it."

The egg was about the size of a balloon, but it was very heavy, and both boys took turns carrying the egg back to their dorms. They brought it into Kirishima's room, since Midoriya's room had alot of expensive All Might merch that the baby dragon might ruin once it hatched. Midoriya wrapped a fluffy blanket around the egg, as Kirishima set up a few pillows to use as a nest.

Midoriya placed the egg in the nest of pillows, and stood next to Kirishima, chuckling at the idea of their situation, "we're actually going to try to raise a baby dragon, in the dorms.."

"Yep!!"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

After the pair had adopted the dragon egg, they had both started to change. It was unnoticable at first, but both of them were starting to become extremely protective of their egg. Neither one would let anyone go in Kirishima's room, let alone near their egg. No one even knew about the egg, other than them. Similarly, they were protective over their own possesions as well, no one could touch their things without being growled at. Except, of course, eachother.

It was worrying to their classmates. No one had any idea what had caused it, but they wanted to find out what so that they could help the two of them. And they had a feeling that the cause might just be in Kirishima's room....

"Alright, here's the plan. We're gonna sneak into Kirishima-kun's room while he and Midoriya-kun are sleeping, and see what those two are trying to hide. Then, we can help them both with whatever is going on!" Sero said to the rest of the students in his dorm room. The group consisted of him, Ashido, Uraraka, Kaminari, Todoroki, Asui, and suprisingly enough, Bakugou.

"Kero, couldn't we just ask them what's going on?" Asui asked, and Uraraka shook her head. "Ashido-chan and I already tried. They didn't seem to notice that they were acting differently, and brushed it off as nothing.."

"Yeah! It's so unlike them, like they've been brainwashed or something!!" Ashido exclaimed. Kaminari and Todoroki both nodded in agreement. Bakugou rolled his eyes, "this is stupid, Shitty Hair and Deku should be able to protect themselves from being brainwashed. Let's just get it over with."

"Alright, we'll do this tonight"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Ashido melted the lock on Kirishima's door, before turning the knob and opening it. Everyone involved were wearing all black, in order to go unseen. They snuck into the room, hearing Kirishima's soft snores the moment they entered.

In the center of the room, was a silver, scaly egg, shinning in the darkness. The glow pulsed, almost like a heartbeat. "That's not good..." Sero muttered, looking at the egg. Kaminari approached it, but Sero held him back, "do not touch that egg."

"Why? What's wrong with it?" Uraraka asked, tilting her head slightly. Sero sighed, "cursed dragon egg. You can tell by it's glow. Touch it, and you fall under it's curse. And nothing can get rid of the curse."

"So, what can we do to help them..?" Mina questioned, and Sero merely shook his head.

"Of-fucking-course those idiots do something like this." Bakugou grumbled.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When Kirishima woke up that day, he noticed that his skin seemed thicker than usual. He blamed it on his quirk acting strange, up until Midoriya told him that he noticed the same thing. "We should probably go to Recovery Girl... She might know whats going on." Midoriya said, rubbing his now almost scaly skin. "Yeah, she can help us!" Kirishima agreed.

In that very moment, they began to grow, until they were twice their original size. "..Or, we could stay in the dorm..." Midoriya mumbled.

Their skin finished transforming, now shiny scales instead of human skin. Kirishima had red scales, and Midoriya green. Pain filled their bodies up until their transformation was complete...

Long, scaly tails emerged from their backs. Large wings sprouting out of their shoulders, the huge wingspan taking up a large portion of the room. Horns started poking threw the scales, trailing from their foreheads down to the bottoms of their necks. Their teeth sharpened into fangs, and their mouths started to widen, dipping near the middle. Their fingers elongated into claws.

The egg disappeared into a puff of smoke, and the boys looked at eachother.

They were dragons.

"This can't be good.."

Midoriya walked up to the door, and sighed, "We're too big to fit..."

"Where'd the egg go?!" Kirishima asked, looking around. "I... think that might've been a cursed egg..." Midoriya said, "not a real one.... We'll be dragons for the rest of our lives..."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Once the pair had been found trapped in the dorm room by the heroes, it was decided to kick them out of the city. They had kept their quirks, meaning both of them would make extremely dangerous dragons, and their large size didn't help that matter.

The two of them had ended up flying into the forest, where they found a young girl named Eri. She ended up following them into a large cave, big enough for the two dragons.

They ended up taking care of her, basically adopting her as their own.

Due to the magical properities of the cave, Eri ended up transforming as well. Not as much as Kirishima and Midoriya, but she grew wings and a long, scaly tail like theirs. She went into the city often, telling everyone that the dragon mutations were her quirk. From the city, she had learned about heroes.

After she had told her dads about heroes, and that she wanted to be one, they allowed for her to apply for the UA entrance exam.

And, she passed it.

"Be careful, okay Eri?" Midoriya said, ruffling her hair with his large, clawed hands. Kirishima chuckled, "Zuzu, it'll be fine! We went to UA too, remember?"

"Don't worry, Daddy, Papa! I'll be fine! Bye, I love you!!"

With that, Eri flew off too UA...

I might make a second gen story based off this, or maybe not.
