"Careful, this cargo is very deadly and delicate," the Manager said as Soldiers steadied the cargo's cage. "Bakugou open the gate into the enclosure.''

Bakugou nodded as he pulled the large door open, the others slowly lined up the crate and the door. Shoto quickly climbed up onto the crate and slowly lifted the crate door. The monster inside was still as all the shoulders readied their tasers. Suddenly the monster slams the side of the cage, causing Shoto to slip and fall of the side. The creature inside grabbed the white and red-haired boy by his ankle and attempted to pull the boy in.

Bakugou quickly acted, grabbing Shoto's hand, and tried to pull his co-worker out of the monster's grasp. The others quickly started to poke the creature with their tasers on a stick.

"Taze him! Taze Him!!" The manager shouted.

The Naga screeched in pain as it quickly released Shoto and slithered away into the lush enclosed.

"Thanks, Bakugou," Shoto thanked slowly as Bakugou pulled him to his feet.

"Just pay better attention next time," Bakugou scoffed as he walked off.

Inside the observation lab, Izuku and Mono looked into the enclosed from the second floor, scanning for the Naga.

"Can you see it?" Izuku asked.

"No, so according to the information this Naga is supposed to be gravid," Momo said as she flipped through her papers.

"Yes, meaning that we will have more specimens to observe and study," said the head scientist.

"Yes, we could observe Naga's life development," Momo agreed.

Izuku stared back into the enclosure and saw a (scale color) tail sticking out of the bushes below. The young Naga slowly climbed his way up a large tree, to get out of the view of the humans. His oviducts were aching for a while now, yet all the stress of current events wasn't helping him.

"Why are these humans so cruel," the Naga mumbled to himself.

-----------------------------

(4 days later)

These past few days were hell on earth, these humans some in with their strange weapons that fire strange fluffy thing. The moment it bites my skin, I lose all control of my body as I fall asleep. These humans would poke and pride me while doing all sorts of random things to me. Especially feeling up my tail, to feel for my eggs. These humans wanted my Babies, and I won't let them have them.

The only kind human was the one with wild green hair, wh didn't do anything to me but feed me, and talk to me. He seemed to be the only one to notice I was in pain. Though I can't be sure if I can entirely trust him, so most of the time I distract him by asking about him.

This human's name is Izuku, but his two lovers nickname him Deku. I wasn't aware that humans could have so many lovers, his lovers were humans named Shoto and Bakugo. It was strange, cause Naga mate with only one other for their entire life, so the thought of multiple boggled me. Though there were Naga who wished to raise a family on their own, with no mate. Deku even showed me a photo of them on time.

"Oh, it's that human I tried to strange that one time," I said simply as I pointed to the Shoto human.

"You what?!" Deku gasped.

"Don't worry Bakugo human stopped me, you have strong mates that's for sure. Very lucky," I said, trying to calm down the green-haired human.

"Well yes, but why did you try to strangle Shoto?" Izuku asked.

"Cause he was one of the humans who put me here. I was very angry at the time," I explained.

"Oi, Deku! Be careful around the Naga," Bakugo human shouted as he and Shoto human ran over.

I quickly slithered off to suffer in pain, away from human eyes.

-------------------------------------

"Deku, remember Naga's are very powerful beings. The East thing we want is for you to end up being hurt," Shoto warned.

"I'm aware, but this Naga is in constant pain," Deku said sadly.

"What do you mean?" Bakugou asked as looked up from the weapon he was cleaning.

"Y/n is Gravid, he's expected to lay eggs soon, but he is holding them in," Deku answered.

"Why would he do that?" Shoto asked.

"I'm not sure, maybe stress from a new environment possible," Izuku sighed as he looked through his notes.

-----------------------------

"So your name is Y/n?" Shoto asked.

Deku decided to properly introduce Bakugo and Shoto to Y/n the naga. The three were wary of each other for a time but soon understood each other.

"So how are your oviducts Y/n?" Deku asked as he did his usual check-up.

"Sore as always," Y/n mumbled.

"Why don't you lay them, this can't be healthy for you or the eggs?" Bakugou asked with a grunt.

"No, the other humans will take them away from me!" Y/n screamed as he backed away.

"Y/n, please relax. The stress can't be good for you," Shoto said as he slowly held out his hands.

"No, I can't lose my last remnants of him," Y/n sobbed into his hands.

"H-him?" Izuku asked.

"Shinou, he was my lover and love," Y/n said softly.

"W-what happened to him?" Shoto asked.

"A few days before I was caught, Shinsou and I became mates to each other for eternity. I was expected when bad humans came, Shinsou tried to protect me and our children. Yet they took his life forcing me to flee," Y/n explained with his hands covering his face.

----------------------

The three humans sat there in silence as that information sank in. Y/n sobbed quietly to himself as he returned to his tree. Deku was distraught for a while as he sat in his office.

"Is that true, they plan to take his eggs?" Bakugou asked.

"The head scientist and many others would want to study them, and since not much of anything is know about them. Many scientists believe that nagas are like normal snakes and will simply leave there young once laid," Deku explained.

"I don't get that impression from Y/n though. Wouldn't he have laid them and be done with it?" Shoto asked.

"That's what I tried to explain, but they simply took that as. " Well, I guess a C section is in order," Deku sighed as his eyes watered in frustration.

"So they opted to take them by force?" Bakugou growled.

"They said they fear some sort of egg binding may occur if they don't remove the eggs," Deku said sadly.

"Sounds like excuses to me," Shoto said with a glare.

"I'm just an assistant researcher, I have little authority in this building," Izuku said as he began cleaning up his desk.

"But you still have access to almost every section of this facility don't you?" Bakugou asked as he somewhat softly grabbed Deku's wrist.

"Yes, why-... No, I know what you too are thinking," Deku gasped.

"Will you assist us, Deku?" Shoto asked

------------------

The facility was blaring with alarms as security and scientist ran about, screaming about the missing Naga. Little do they know a few miles away from the in an alone moving truck, the trio and naga were all loaded inside as Bakugou drove.

"How's Y/n doing?" Bakugou asked as he stared ahead at the road.

"He's doing well he has already passed 5 eggs," Izuku said as he handed the eggs to Shoto.

Shoto was having a hard time not gagged at the slim-covered eggs Deku was giving him. "H-how many more can Y/n possible have?" Shoto gagged slightly.

"Just one more," Izuku said as he massaged Y/n's stomach. "You are doing so well."

Y/n gave one final push as the final egg left his oviducts. Y/n panted in exhaustion, while Izuku and Shoto carefully placed his eggs into the backpack for Y/n. Bakugou soon pulled over once they got far into the woods, Y/n quickly grabbed the bag of his eggs and quickly slithered out of the truck. As he ran into the woods, he paused and turned back to look at the three in confusion.

"Why do you help me? You have betrayed your fellow humans. they surely won't except you back," Y/n asked.

"Why not?" Deku asked.

"Throughout history, Naga and humans don't have the best of relations. I have done nothing to earn your help," Y/n said with confusion in his eyes.

"Naga and humans have quite a bit in common, and nagas are intelligent beings that deserve the respect of their own," Shoto added.

"What they said," Bakugou said simply as he climbed back into the truck.

"Thank you... Kind humans," Y/n smiled as he vanished into the woods.

-------------------

(4 years later)

"You brats get off me," Bakugou growled as he was wrapped up by 4 naga children's tails.

"Hold us uncle Bakugou,"

"I wanna be carried,"

"No, pick me up," the young naga children whined.

Shoto simply watched with a tiny smile as he carried 2 of the naga children. Izuku smiled as he observed the children as they played with their human uncles. Y/n was resting on the porch next to Izuku, the know freelance researcher took notes of the nagas. Izuku was first to point out that some Naga had purple hair and scales, unlike Y/n with H/c hair and scales.

"They look just like Shinsou," Y/n smiled softly as he watched them play with Shoto and Bakugo.

"How are you handling rising six on your own?" Izuku asked.

"It's tiring but worth it. I'm surprised you chose to house permanently so close to naga-filled woods," Y/n commented.

"Well, I always have been interested in them, and know I can learn about them more naturally this way," Izuku smiled.

"You humans are so strange," Y/n yawned with a smile.

"Oi, Y/n Get your kids! There Suffocating me!" Bakugou shouted.

"Aright it's time to go home children!" Y/n called as he slithered over to Bakugo.

"AWWW!!" The babies whined as they began to climb onto their father.

"When can we see them again?" A purple-haired Naga child asked.

"When they are not busy, but for now we must go," Y/n smiled as he leads them back into the thick forests.

"be good now," Shoto said to them with a smile.

The children looked back as they waved goodbye to the humans, disappearing into the forest with their father.
