"We're going on a what?" questioned Y/N.

"We're going on a patrol. A hero patrol." Ryuko said.

"But what about my limit training?"

"We'll do that tomorrow. I want you to experience when it comes to keep an eye on villains and dangers that will cause trouble for the citizens." Ryuko explained. "I also got a call that they need help in Hosu City."

Y/N tensed at that part as she remembered that's where Tenya is when she was with him. Her gut told her something bad will happen and she's going to find out.

"...Okay." Y/N nodded and got her costume on and faced her.

"Let's go." Ryuko said, patting her head and they both walked out of the agency.

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

They are now in the train as they head towards Hosu City. Ryuko explained to her that there are villains coming out during the night and it would be easy for Y/N to get an experience. As they were sitting down, Y/N suddenly feel eyes on her. And she didn't like it. She turned to see a fairly tall, pale young man of a slim, somewhat-lanky build, described to be in his early twenties. He has longish, black hair that spikes up around his head, hanging low over his eyes, which are thin, turquoise in color, and heavily lidded. His most striking features, however, are undoubtedly the patches of gnarled, wrinkled, purple skin that cover much of his lower face and neck, all the way down past his collarbone, below his eyes and on his arms. These appear to be attached to the rest of his skin by multiple, crude surgical staples or hoop piercings, making it impossible to tell if these scars were accidental or self-inflicted. He gave her the look that looks like he's after his prey and his eyes are filled with bordem, but with mysterious secrets he rather keep. Y/N looked at him in confusion as to ask him if there's a problem, but he just gave her the tinge of smirk and looked away.

Strange. Y/N shrugged it off and laid her head against the seat. By the time train had stopped, they have reached their destination to Hosu City. She looked back at the man only to see him gone. She raised her eyebrow in confusion and went out of the bus along with Ryuko. You looked around to see it's dark already. Just as you both stepped out of the bus, the rather familiar scent alarmed you.

"Ryuko! Get down!!" she shouted, pulling her down.

A loud thump was heard along with the high pitched cry. Everyone screamed in horror and ran away from the train station. Y/N looked up to see the Nomu, but with different color skin and it had wings.

"Another Nomu?!!" she yelled.

Ryuko got up and quickly changed into the dragon along with you changing into Indoraptor. Ryuko pinned it down with her claws. Y/N jumped over her and clawed the brain of the Nomu, pierce it, and bit it down hard with her sharp teeth, cracked it's neck, and pulled the neck out until it stopped moving. You took a look at your surrounding to see chaos the city had been thrown into. The city was releasing puff of pitch black smoke, fierce fires scattered wildly along the buildings and explosions going off on occassion just to top it off.

"What the heck is going on?" Y/N said, changing back into a human.

"Y/N!" Ryuko called, pointing something behind you.

Y/N turn around to see another Nomu tearing down the train, scaring the citizens. You quickly jumped and wrapped your arms around the Nomu's neck. It yelled, trying to get you off as they both spun around. Nomu removed the claws from the train. Ryuko brought everyone out of the train to get them to safety.

Y/N brought out her claws and stabbed the Nomu on it's exposed brain. It screamed in pain and you twisted it and sliced the neck off of its body before it collapsed. The thud was heard of the body hitting the ground with a rough landing.

"Is everyone okay?" Y/N asked.

Everyone nodded as Ryuko ordered them to stay here where it's safe as both of you ran towards the street where the heroes are fighting against the Nomus. The muscle Nomu ran towards you both and you both pinned it down as Ryuko punched the brain of Nomu, making a loud splat. After Nomu was down, Y/N helped the hero who wears blue and white, skin-tight, long-sleeved shirt that tucks into his orange gloves, dark pants, white boots, and sports a signature helmet that features a fish-like fin and blue visor. Y/N threw the Nomu towards the pole where it's brain hits and you ran over to it and stomped its head off and it died. She flipped over just in time to see the flying Nomu diving down to catch her, but missed. It did caught the blue and white fish-like hero. She grabbed the pole and pulled it down, and swung herself towards them. She caught Nomu's leg and climbed up and stabbed the brain. She managed to control the flight of it as they landed. She got off of it and helped the hero up.

"Thanks, uh..."

"Indomitable Thief." she replied.

"Manual. Your the first year, right? Do you know where Iida is? I can't find him." Manual said.

"You mean he left? Where?"

"I don't know, but he have been acting strange. I fear he's going after someone."

That made Y/N realized that Tenya is going after the Hero Killer.

"That idiot...! I told him not to go near him!!"

Her phone in her pocket vibrated in time and she picked it up to see it was from Izuku. And it looks like he had given her the map of where he's at. Which means he's in Hosu City as well. When she looked at the map, she quickly predicted that's where Tenya is. It took her a moment to realize what he was trying to say, he should have been more specific.

"Ryuko! I'm going after my friend! He's in danger!"

Ryuko looked at her before she nodded, knowing she can handle herself.

"Okay. I'm allowing you to use your Quirk if needed! Be careful!"

She nodded and looked back at Manual.

"I'll get him back safe and sound before he does anything stupid."

Manual nodded.

"I trust you."

With that Y/N ran off in speed with her dinosaur Quirk.

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

Y/N took a whiff of the scent to follow and was just in time to hear fighting from outside of the alleyway. She turned the corner and found Tenya on the ground bleeding, Izuku on the ground paralyzed, and surprisingly Shoto. Y/N had no idea that Shoto would come to Hosu City as well. The other thing she saw was the tall man with a muscular built to him with black messy hair and red eyes. He wears a combative outfit armed with sharp bladed weapons, a long torn scarf and bandana around his neck and eyes. He also wears bandages around his arms and boots with spikes on the toes. His hair was much longer and kept in a straightened ponytail and wore a mask that covered the entirety of his face. His overall outfit was heavily armed with combative armor.

She quietly gasped to see the hero killer pouncing towards Shoto with his long pointed tongue to where his cheek was being scratched earlier. Luckily, Shoto brought out fire from his left arm, making him go back that is close to her as she awed that he's finally using fire. She remembered that his villain name is Stain which really suits him since she found out about him while searching and always leave blood on heroes he killed. Y/N looked at Stain who was talking and she immediately changed into her dinosaur form and hid through the dark and went behind him without him noticing. Once she was close, she pinned him down with her claws and took the sword out of his grasp and snapped it in half with her sharp teeth and threw it away. 

Y/N growled at Stain and digged her claws into his back as he struggled to get up.

"Y/N!!" the boys exclaimed.

Y/N gave Tenya the glare, making him flinch and gulp in knowing that he's in big trouble.

"I didn't think you had gotten a message!" Izuku said, looking relieved.

"Y/N.." Shoto said.

Y/N in her Indoraptor ignored them and stare down at Stain, daring him to make a move. Stain with his smart move, quickly grabbed the dagger from his pocket and stabbed her left clawed hand. She roared in pain and he pushed her off from behind and they both moved back from each other.

"The Indoraptor. You're Y/N L/N. The one that bastard wouldn't stop talking about." Stain said with a smirk.

Y/N who was back into a human was holding her hand that is being stabbed through.

"You're with the League of Villains?"

"I didn't completely joined them. I just came for a mission. You got a nerve for coming here to stop me to face more brats." he said with a scowl.

Y/N gritted her teeth and pulled the dagger out of her hand with a hard tug. The boys cringed to see her hand covered in blood, but it didn't faze her and gave Stain the intimidating glare.

"Let's get this over with." she said before dashing towards him.

Stain threw more knives at her and she dodged them and jumped over them and Stain and landed next to Shoto. Stain brought out another sword (pretend he has two) and lunged towards the two. He raised his weapon to cut one of them down, and boy, he was fast.

But not as fast as Shoto as he raised the ice glaciers at him as a shield. Y/N quickly jumped up and ran on ice towards Stain as he cut down some ice and punched him in the face with her non-injured right fist, making him push back.

"Y/N! Please, no! Leave! I don't want you getting wrapped up in this as well! Please!" Tenya desparately said, but she only gave him a growl and ignored him.

"He's strong!" Shoto shouted, bringing out fire when Stain charged at them again.

Y/N disappeared in the dark and went behind Stain and whacked him in the head with her tail. He let out a loud grunt. He swung his sword at her, but she blocked his attack with her big claws as the blades created sparks against each other.

"Y/N, watch out! Don't let him get to you with any of his blades! Once he digest your blood, you'll be paralyzed!" Izuku warned.

Y/N grunted with a nod and dodged his swing from his sword and moved further back. She saw the knife she had thrown and grabbed it, whipping off the blood with her cape and left it there in case he tried to lick off some remaining blood he sees from the blade. Shoto brought out fire again to distract Stain as she quickly tore off some cape and wrapped it around her hand tight as she could and tied it up in a knot.

She climbed up the building and crawled her way towards the group as she had the ability to do that without her dinosaur form. Y/N went back to Shoto as she helped him fend Stain off.

"Just stop it... why are you doing this?..." Tenya shakily said. "This fight is with me. I inherited my brother's name. I'm the one that should stop him. The Hero Killer is mine!"

"You're Ingenium now? That's strange." Shoto said, creating and rising the ice glaciers from the ground, and Stain jumped up. "The Ingenium I knew before never had that look on his face."

"Wow, so he has a dark side now? Kinda like you and me, Shoto." Y/N said in sarcastic tone, trying to claw at Stain.

"Careful, Y/N, Todoroki!" Izuku said.

In an instant flash, Stain cut down the glaciers into a large chunk and revealed himself with a creepy grin on his face.

"You block your own field of vision against an opponent whose faster than you. Rooky mistake."

The large chunk that was being cut fell right above Y/N's head and she quickly dodged it. Shoto's left arm bursted into flames about to fire him when his arm being were pierced from two daggers that were being thrown.

"Shoto!"

Stain ran towards the pro hero who dressed up as Native, prepared to impale him and she quickly ran towards him to protect that man from Stain. A sudden green blur that glowed flew past her, taking Stain towards the wall across, making the debris and dirt fall off. She was shocked to see Izuku okay and is now moving.

"Izuku/Midoriya!" both Y/N and Shoto said in unison.

"I'm not sure why, but I'm able to move now!"

"So he has a time limit.." Shoto guessed, gripping onto his bleeding left arm tightly.

Y/N walked over to him and took out the daggers from his arm and tore out some more cape and wrapped it around his arm tight.

"You don't have to do that."

"Well, I insist. Don't want Stain to lick your blood off." she said and finally tied it in a knot.

"...Thanks.." he said looking at his wrapped up arm.

She nodded and went back to Stain when she heard the pro hero.

"No... that kid should have been the last one to be freed. I still can't move a muscle."

Stain jabbed his elbow into Izuku's side and knocked the teen off of him. Izuku fell to the floor and Stain landed behind him on his feet as Shoto warned Izuku to dodge and brought out the line of ice towards Stain. Both of them jumped out of the way before it could reach either of them.

Izuku was quick to make his way over back to his friends and crouched down beside Y/N.

"He swallows a person's blood to freeze them, but I was the one free first. I've got three different guesses why." he explained. "His Quirk could be less effective the more people he uses it on; the amount ingested could play into how long it works; or-"

"Depending on person's blood type." Y/N finished it and Izuku nodded in affirmation.

"If it's the last one... my blood type is B." the pro hero said.

"I'm... type A." Tenya said.

"So you've figured it out. Bravo. Very impressive." Stain smirked deviously.

Izuku clenched his jaw.

"It doesn't really help us to know how his Quirk works, though."

"I thought we could hurry and carry those out of here, but it's no good. He's too fast; he can dodge ice and fire. I'd had to leave myself unguarded." Shoto said. "Our best chance is to hold until the pros arrive and avoid close-combat."

"No. Not with you injured. The more you move the more blood will come and I don't think my cape can hold much long to prevent the blood from flowing." Y/N said. "I have to be more careful with my hand if I have to defend myself."

"Y/N's right. I'll distract him while you two support me from behind. Sound like a plan?"

Y/N nodded and Izuku turned to Shoto, asking him too. Shoto's gaze moved to Izuku to Y/N for a moment, more to her and turned forward.

"You want us to take a pretty big risk..... Okay."

Izuku nodded and Y/N got into her fighting stance with her right claw up to her face.

"Let's do this."

"Three against one, huh? This won't be easy."

As Izuku and Shoto fought against Stain, Y/N looked back and walked over to Tenya with a glare and kneeled down. She stared at the dagger on his left shoulder and grabbed the handle.

"This will hurt. So clench your teeth."

Tenya nodded as she did a one hard tug, making him bit his lip to stop the screaming. She wrapped it around his shoulder and made it very tight on purpose because she's still mad at him as he yelped in pain. She then tied it and looked back to see her cape almost gone, but she doesn't care.

"You. You are so busted for this. You reckless, irresponsible, stupid!"

Tenya looked up at her with pained, guilty eyes.

"Y/N, I'm sorry. I didn't want you to get wrapped up in this. I didn't want this. And I never meant to break your promise when you warned me, but I was blinded with anger and revenge. Please, you all need to leave. This is my battle. You all need to get as far away from here as possible..!"

"No." she replied as her eyes darkened.

"..What?"

"You're an idiot for crying out loud. We are not leaving you because that's not what friends do. They look out for each other not caring about themselves, but for someone else they really care for. We're still classmates and we must look out for each other."

"I gotta thank Eijiro for all of this that I never get to have.."

"Y/N..."

Y/N picked Tenya up for him to sit up before looking back to see her friends struggling to take down Stain. She stood up without looking at him.

"If you want to make your brother proud and to honor his name, then you better stand up." she then looked at him with her red glowing eyes that are filled with anger. "BE INGENIUM!!"

With that, she's gone and ran at Stain and tried to kick him, but he grabbed it and threw her over towards Izuku. Izuku quickly catched her and landed safely away from Stain. She thanked him for the save. Shoto brought out the tall spikes of ice, but Stain zoomed through and Shoto quickly shot a powerful amount of fire at him, but he just swiftly dodges them.

"Hasn't anyone ever told you that you rely on your Quirk too much? It makes you a careless fighter."

Time seemed to slow down and Stain skillfully dodged all of Shoto's attacks, and was now dashing underneath his arm. He held up his sword right underneath his arm as he was about to cut his arm off.

"Izuku! Throw me!!" she shouted.

Izuku nodded without hesitation and gave her a powerful throw with his 5% Detriot Smash for her to go faster. Y/N brought out her claws and in slow motion, she was in front of Shoto and held the blade of the sword in place with her right hand as she struggled to stop him from moving any further. Stain smirked deviously and kept pushing the blade closer to her. She gripped onto the sword and the blade started to crack since her claws are stronger and finally it snapped into pieces, making Stain surprised.

Stain was then pushed back by none other than Tenya with his powerful kick after he landed back on his feet.

"Iida!"

"So you're free too? I guess his Quirk wasn't as great as I thought it was." Shoto turned to blue haired friend.

Y/N shook her clawed right hand away from some small pieces of blades before turning it back to her normal hand. She looked at Tenya with a small smile.

"Y/N, Todoroki, Midoriya... I apologize. This has nothing to do with any of you." Tenya said as he stood up straight. "I won't let any of you shed any more blood for me."

"You're hopeless." the villain coldly said.

Y/N cracked her neck and distracted Stain with her intimidating glare and she got to make him flinch from staring into her eyes.

"Todoroki! Freeze my leg for me." Tenya shouted. "Without blocking the exhaust pipes!"

The pro hero tried to stop the students for taking any step further as he told them that Stain is only after himself and Tenya. But kids never listen as they are determined to help get the job done. Stain struggled to get out of her eyes and when you removed them, he found himself already surrounded. Y/N running at him in speed and jumped overthe balconies with her tail sticking out. Izuku followed her lead, shooting off against the building wall with a tight fist. Tenya in the blink of an eye was behind Stain with his leg behind with a powerful force ready to be released. Y/N who was in front of the Hero Killer's side had her tail ready to whack.

Izuku unleashed his deadly punch against Stain's face, causing his neck to turn a little too far for him to snap it off. Tenya had his recipro burst fly straight into the side of his stomach, the villain's body contorted to the impact and broke a few bones. And lastly, Y/N whacked Stain's back with her tail, hearing some sickening crack, and impaled his arm with her three digit claws. The trio rolled down the hill of ice that was made to catch them and got hit in the head by the ice wall to stop them from sliding, although it caused them to get hurt. Y/N gave Shoto a glare, rubbing the back of her neck.

"Damn you.."

"Get up! He's still..."

Shoto ceased as all four of them stared out of disbelief at the unmoving body of the Hero Killer.

"He's out cold, right?"

"It's over." Y/N said and hung her head down in tiredness. "Good riddance."
