Two days since the Hosu incident, and five days since they started their internships. On the news, the hero killer was the talk of the town. When seven pro heroes and three high school students came across the hero killer, Endeavor and Y/N with Ryukyu's permission rushed over and took care of the situation. That was the official story released by the police. Izuku, Shoto, and Tenya's names were not made in public much to Y/N's disappointment, and their injuries were explained away as accidents that happened during their internships.

The night Tenya got the results of the examination of his injured arms, he went back to his mom to his parents' house. As for Shoto and Y/N, who have relatively light injuries return to their internship because they want to learn what they can, especially Y/N's Quirk limits. Shoto also want to see his old man's expression who clearly didn't take down hero killer. Izuku had stay in the hospital for a while because his injuries from Stain were not fully healed yet.

The day when Y/N first went to the press with Endeavor, she felt very uncomfortable with the whole crowd taking pictures of her and staring at her as it reminds her when she was about to get sold like a slave. She even have to literally answer every questions they ask and it's clearly annoying. But there are people who admired her as she had already a few fans as they remembered her in the video that went viral when she took down the hard head dinosaur that run like a bull. And now the hero killer incident. Y/N was surprised to see everyone loving her as a fan. Her and Ryukyu kept on training to get the Quirk limit under control. Y/N had made some few dents in the training room area since they can't go back to the forest if there's wild animals invading them, especially Cheetah.

As for everyone else from Class A, their internship went quiet well. Some were weird and some were interesting. Tsu, hero name: Froppy was on the boat with her internship's sidekick Sirius along with her intern who's the captain of the boat Selkie, the seal hero. They are apparently searching for the stowaways. It was almost night time and Selkie was searching for them with his Quirk that are seals' abilities. When he got back, they found them and him and his crew were taken down or blinded by the oil. But Tsu and Sirius help take down the villains and knocked them out and tied up. Selkie thanked them that they were able to catch them after getting the oil out of his eyes. Tsu was glad to come to this internship and started to understand a little of what's really important for a hero.

Suddenly, they felt a rumble from underneath the ocean and a strange roar. Selkie quickly came to their aid, feeling a strange and scary presence coming their way. All of the sudden, they see a fin of the shark and their eyebrows narrowed in confusion when it jumped over the ocean. Once the shark did, it was caught by the gigantic jaws as it roar loudly and rise high above the surface. You could see with the bright moon shine it is depicted with dark blue skin and a gray underbelly. It also lacks a tail fluke and moves in a snake-like motion like older restorations. Mosasaurus. It's length is 18 meters (60 ft).

"W-What is that...?!" Sirius stammered in fright.

"I-I don't know." Selkie said, not knowing what the heck that is.

"Kero..." Tsu said, feeling both scared and surprised.

Mosasaurus snapped it's jaws closed after catching the shark in its mouth and dived back down into the ocean, creating a huge splash, leaving them wet and soaked. It was then gone like it was nothing, swimming down deep. Tsu gotta ask Y/N what was that that she just see and had took a pic of the Mosasaurus with the help of the bright moon before it disappeared. She managed to get a good close with her phone.

Selkie, Sirius, and the sailors who are Selkie's sidekicks had no words to say as they just witnissed the large aquatic carnivorus dinosaur. But they eventually took the stowaways with them towards the police after they set sail back home. Tsu had shown them the picture of the Mosasaurus as the police sighed from another dinosaur sight incident while also strangely excited. Tsu will never forget her day in internship as well as seeing the real dinosaur for the first time.

"Thank you so much for taking good care of me, Ryuko." Y/N bowed, holding her hero costume suitcase as she was back in her U.A. high school uniform.

"It's no problem. I look forward to working with you again once you get your license." Ryuko smiled, escorting her to the bus station.

"I hope to see you again when the time is right. Thank you again for helping me with my limit." Y/N said. "I'm still getting there."

"That's good."

After they are in the station where the bus is already here, Ryuko waved goodbye as Y/N waved back before the door closes.

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

Everyone are back in U.A. once again as Y/N slid the door open and what she sees was unexpecting and covered her mouth.

"Seriously?! Seriously, Bakugo?!" laughed Eijiro and Hanta.

"Stop laughing!" growled Katsuki with a nice combed down hair instead of his normally spiked up hair. "My hair's gotten used to it, so it won't go back even after I wash it!"

Y/N couldn't take it and started laughing, gaining attention of the boys. She pointed at Katsuki with tears coming out while holding her belly.

"What the heck?! That's so not like you! What are you trying to do? Impress the ladies?" she said and laughed even harder.

Eijiro had to walk over to her to hold her so both him and her wouldn't fall over.

"Hey, stop laughing! I'll kill you!"

"I'd like to see you try, Side-Part Boy!" Hanta teased.

"What'd you say?!" Katsuki yelled with much more anger as his hair was poofed up, making the trio laugh even harder.

"It's back!"

Y/N had to block Katsuki from lunging for the two boys with her dinosaur book towards his face. Katsuki's face was hit with a loud pained grunt. This made the boys laugh again as Katsuki yelled in anger, trying to attack Y/N, but she just grabbed him by the face to stop him. He struggled to get away as she did a fake yawn, looking bored.

"Wow, you even got to fight villains?" Mina asked Kyoka. "I'm so jealous!"

"I just helped people evacuate and did logistical suppport, so I didn't do any actual fighting, though."

"It's still amazing, though!"

"All I did was train and go on patrols, too." Tsu spoke up. "There was one time when we caught smugglers from a neighboring country."

"That's crazy!" exclaimed Mina and Kyoka.

"Oh, Y/N. I actually wanted to tell you something. I saw something right after we caught smugglers." Tsu called over to Y/N.

Y/N let go of Katsuki's face, making him drop to the floor. She walked over to them and asked.

"Yes? What is it?"

"I saw a gigantic creature from the ocean. It even ate the shark in one bite."

Tsu took out her phone and showed her the picture from last night. Mina and Kyoka took a look too until they exclaimed again, but with fear and shock.

"That's even more crazy! And scary!"

"It's a Mosasaurus!" Y/N gasped, taking out her book and showed them the exact image of the Mosasaurus.

"Woah! Is it that huge?" Kyoka said.

"It's about 18 meters long. It was a genus of large aquatic carnivorous lizard from the Late Cretaceous about 70-66 million years ago. It fed on such prey as seabirds, sharks, large fish, plesiosaurs and even other mosasaurs." she explained.

"Kero. That sounds interesting and scary."

"Eat sharks? That's rare." Mina said.

"I know." Y/N said. "I'm actually quite jealous that you get to see one, Tsu. Since you are the frog that can work with water."

This made Tsu blush with a cute ribbit sound and quickly turned to Ochaco.

"What about you, Ochaco? How was your week?"

But what they only see is Ochaco in her fighting pose with a strange aura around her.

"It was very worthwhile..."

"Ochaco's awakened, huh?"

"She went to that battle hero's place, right?" Kyoka muttered.

"I'm pretty sure it shows she had trained well." Y/N smiled.

"That's a huge change for just one week." Denki wearily eyed at Ochaco next to his buddy Mineta.

"Change? That's not it, Kaminari." Mineta wagged his finger and his face changed to fear and started biting his finger. "Women are all demons. They're just hiding their true personalities."

This made Y/N smirk that Mt. Lady did a good job at scaring Mineta.

"What did you see at Mt. Lady's place?!" Denki exclaimed, stopping him from biting his finger. "I was kind of fawned over and had a good time. But the ones who changed the most, or at least went through the most were you four, right?"

Izuku and Tenya were around Shoto's desk, and Y/N no later came over to check on them with a book in hand.

"Oh, yeah! The hero killer!" Hanta exclaimed.

"I'm glad you guys made it out alive! Seriously." Eijiro smiled weakly at them, especially Y/N. "How's your hand, Y/N?"

Y/N looked at her hand without any bandages as it showed a scar where the dagger had stabbed through. After her hand was healed, it was left that way. But she was okay with it.

"It's fine. It's just a scratch."

"I heard Y/N and Endeavor saved you, right?" Rikido said.

Y/N cringed that he had to say that.

"That's amazing! As expected from the Dinosaur Whisperer and the number two hero!" Toru exclaimed.

"Yeah. He saved us." Shoto said, staring at Y/N.

"Yeah." Izuku said.

"I saw on the news that the hero killer was connected to the League of Villains." Mashirao spoke up. "Imagining someone that scary coming to USJ freaks me out."

"He is scary, but did you see the video, Ojiro?" Denki asked.

"Video? You mean of the hero killer?"

"Yeah. Seeing that, you can see how he's really single-minded and, like tenacious. Doesn't it almost make you think he's cool?"

"Ahem!!" Y/N coughed out with a glare.

"Kaminari!" Izuku scolded.

"Huh? Oh, Ii- Sorry!" Denki covered his mouth.

"No, it's fine." Tenya said. "It's true that he was tenacious. I understand how people could think he's cool. But he chose purging as a result to his beliefs. No matter what he thinks, that part is definitely wrong. In order to keep anyone else from turning out like me, I will once again walk on the path to becoming a hero!"

"Yeah, Iida!" cheered Izuku.

"Now, it is time to commence class! Everyone, take your seats!"

"He's so loud..." Fumikage sweatdropped.

"And he's back to himself again as class president." Y/N sighed with a smile. "Don't worry, Fumikage. You'll get used to him."

"It's 'cause you talked about weird stuff, Kaminari." Kyoka glared at Denki.

"Sorry about that.."

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

"Okay, I am here." All Might stood there before them.

They are outside by the gigantic building wearing their costumes. Well, except for Y/N. She had asked for a replacement since her cape is ripped and her costume is tearing apart piece by piece and she needs another one that involves with her form. She even gave them something that she rather not tell that could help. She's in her casual clothes that are familiar with the ninja outfit, but it's good for combat training. (Pick anything)

"Anyway, we'll start now. Right, it's hero basic training! Long time, no see, boys and girls! How've you been? For this hero basic training- Since you've all just gotten back from your internships, we'll have some fun with a rescue training race!"

Tenya raised his hand.

"If we are doing rescue training, then we shouldn't we do it at USJ?"

"That place is for training for disasters. Do you remember what I said? That's right! I said 'race'!" All Might said. "This is field Gamma! A dense area filled with factories laid out like an intricate labyrinth. You'll break up into four groups and go through the training one group at a time. When I send out a distress signal from somewhere inside,  you'll all start at once from the outskirts of the city! It's a race to see who will rescue me first!"

All Might then pointed at Katsuki.

"Of course, you'll have to keep the damage to buildings to a minimum."

"Don't point at me!" Katsuki looked away.

"Alright, first group, get in place!"

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

After Izuku's group finished and surprising everyone with Izuku's improvements without breaking his bones and for copying Katsuki's movements. Y/N was concerned about that since Katsuki has grown angry and hoped that things won't make things worst since they never had a talk since you know, childhood. Y/N, Fumikage, Mezo, and Kyoka were on different stand of the building as they got into their stance, getting ready for the race. Once they hear a signal from All Might, they all quickly made their way.

Y/N brought out her tail and use it to swing herself high in the sky. She looked down at the view where she can see her classmates are running, she found a perfect spot to land, she did a cat move as she stood on fours and jumped over the platform with one foot.

"Who do you think will win?" Denki asked. "Mine is for Y/N."

"I believe Y/N would win. She had been improving with lots of more experience than she has." Shoto said.

"Tch. Of course Lizard Freak is obviously gonna win.." Katsuki muttered.

Y/N was getting ahead as she kept on jumping over the platforms and pipes as they are close to the building. Kyoka saw her and tried to follow her move, but she slipped and fell off. Y/N's eyes widen and stopped and jumped down to see Kyoka hanging over the edge with one hand for her to hold. She grabbed her hand and helped her up, bringing her back up.

"Thanks, Y/N."

Y/N nodded and went back to jumping. She's already close as she saw Mezo and Fumikage flying and climbing up. She brought out her claws and started climbing as fast as she can. But they are far ahead of them. That is until the idea came up. As she came close to Fumikage who didn't notice her, she jumped on him and used him as a boost. When she did, he grunted in surprise and saw you as you flew over to Mezo. Dark Shadow was surprised as well. Mezo felt a hand on his leg and looked down to see Y/N. He tried to get her off, but she swung herself onto his back and jumped on it. Y/N flew up and grabbed onto the handle and made it to where All Might is standing, making her the winner.

"Finish!" All Might said. "Congrats, Young Y/N! You have improved well!"

Y/N bowed with a smile as she saw Mezo coming second, Fumikage third, and Kyoka last. They panted while also disappointed none of them won. Y/N gave each of them pats on the head, telling them good job. They smiled and thanked her.

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

After everyone else practice, Y/N is in the girls' locker room with others as she took off her shirt, showing her some abs and wearing a sports bra. Mina and Ochaco took a peek at her and blushed at how buff she is. But Momo noticed something, while blushing, she had some scars like what Eijiro said and no he didn't tell them, on her back, arms, and legs.

"Y/N, what's with those scars?" she asked, making her tense. "S-Sorry! I didn't mean it."

"I-It's fine. They were always there since I was born." Y/N said, looking her back. "I rather not talk about it yet. You'll know one day or another."

Mina suddenly hugged her.

"You can always talk to us whenever something is bothering you, okay?"

Y/N looked at her then to other girls for a moment and slowly nodded.

"Guys. You might wanna cover yourself." Kyoka sighed, leaning against the wall with her earphone jack rising.

"Huh? Why?" Toru asked.

"Mineta, stop!" Tenya scolded from the next door. "Peeping is definitely a criminal act!"

Once they heard that name, they tried to find something to cover themselves.

"My little Mineta is already a criminal act! Yaoyorozu's ample Yaoyoro-boobs! Ashido's slender waist! Hagakure's floating underwear! Uraraka's fine Uraraka-body! Asui's unexpected soft boobies! L/N's curvy body in her glorious abs!!!"

Y/N growled in embarrassment and Mina hugged her tight, covering her. Kyoka had enough and her earphone jack made a quick attack through the hole, stabbing into Mineta's pervy eye.

They could hear him scream in pain.

"Jiro's earphone jack! With its brutal combination of precision and surprise attack abilites, it's super strong!" Izuku yelled from the next door.

"Thanks, Kyoka." Toru huffed in anger.

"How despicable." Momo said. "Let us close this up right away!"

"Agreed!" Y/N nodded.

"I'm the only one he didn't say anything about..." Kyoka gloomed in depression.

"If you're thinking your body is not good, don't listen to that pervert. I think you're beautiful just the way you are." Y/N said noticing her expression.

"A-Ah! Um...thanks...again.."

"My eye! My eye!" Mineta's scream was heard again.

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

Meanwhile, in the lab, Dr. Wu had finally finished his creation and opened it to reveal the egg. He carefully carried it and placed it in the hatchling container with a warm heat of light to keep it warm. He closed the glass door and stared at it with an excited smile.

"Soon, you will be the key that holds the future for this world."

"Doctor. Is it done?" Shigaraki asked, walking inside.

"Oh, yes it is. Hatching will take a while for it to come out. I don't know how long, but I know it will hatch. Once they hatched, it will need a mother."

"And who will it be in order to train that thing to be a killer? What about the gender?"

"Don't know. But I will figure out who will." Dr. Wu replied. "And you'll know about the gender soon. I have a surprise."

"Good." Shigaraki smirked, looking at the egg as he wondered what it would look like.
