Chisaki - I hope you'll forgive my daughter, heroes. I don't know what to do with her. Always playing rough, bumping into things.

Yajin - Chisaki from Shie Hassaikai.

He noticed Izuku's face as both him and Mirio put on his mask to cover his expression.

Mirio - Whoopsie-daisy looks like that darn mask came off again.

Yajin - We should probably get it resized. Hahaha. His energy is horrifying but not as strong as All for One but it's pretty close.

Mirio - I'm so sorry about that. It was our fault, too.

Mirio went on to even bring up the mask as Chisaki just said it was to keep away the filth.

Chisaki - I don't believe I've seen you three around the area before.

Yajin - Well we are new to the area. I'm sure you guessed that much.

Chisaki - What agency do you belong to?...Actually. Aren't you the famous Goku.

Yajin - Hahaha. You must have been informed. Yeah that's me. I'm actually just patrolling this area with my teammates. Come on guys we need to finish patrolling before lunch.

He bend down to grab Izuku as Eri grabbed tightly on both of their arms.

Eri - Please. Please don't go.

Instantly Izuku and Yajin's eyes got a little serious as Izuku spoke up.

Izuku - Excuse me. But your daughter she's shaking.

Chisaki - A reaction to being scolded.

Yajin - Yes. Also there are bandages.

Chisaki - She's an extremely clumsy girl.

Izuku - But...she's shaking. She won't let go. Are these injuries normal for you?

Chisaki got a little serious with Mirio worried that it would get worse. However Chisaki spoke up.

Chisaki - This is embarrassing. Why not talk somewhere more private?

He walked towards the alleyway as Yajin gave Izuku a signal for him to let go of Eri as he picked her up.

Yajin - Eri. Listen to me.

She looked up and saw Yajin look at her and then look back at Chisaki.

I need you to relax. I'm going to be watching over you. This light...will be your protector.

His hand glowed a small yellow orb as it landed on Eri's hand. She looked at him as he smiled and nodded.

Chisaki - Eri disobeys me, no matter what I try.

Mirio - Kids huh? Must not be easy.

Chisaki - Yes. They always believe that they can do whatever they want. It always causes such a pain to fix their messes.

He reached for his left glove as Eri got scared as her eyes met with his but Yajin delivered a glare back at him. He set her down as she clenched her fist hiding the light. Quickly running back to Chisaki which shocked Izuku.

Chisaki - Good. Done with your temper tantrum?

She nodded as he apologized for her actions as he wished them luck on their patrol. But Yajin knew something was up.

Yajin - They're energies....

Izuku - Wai-..

Mirio - He was ready to get violent, that's why she went back. Let's report to Sir.

Yajin - Plus something is wrong...his energy is more strange.

Eventually Mirio called Bubble girl and told her what happened. They met up in the agency as Nighteye apologized.

Nighteye - I should have used Foresight on you. I'm sorry.

Mirio - We also receive some new intel. Chisaki, he has a daughter.

Nighteye - A daughter.

Yajin - No. She's not his daughter.

Everyone looked at him as Mirio looked worried but confused.

Yajin - His energy was crazy but energy is the way I can tell if one person has relation. They had no relation whatsoever.

His energy started to flux as red electricity started to flow.

Yajin - He's tormenting her. She's so scared and alone. I'm gonna make him pay...

Nighteye - Don't let your arrogance cloud your judgeme-

Instantly Yajin got right on Nighteye's face as his eyes told him a different story. But quickly he flew away towards the mountains nearby.

Nighteye - (cough) anyways. I contacted other agency's to help so we'll have a meeting soon. Both of you head back to the agency. We'll finish with patrol.

Izuku and Mirio were left standing there in the rain with a sick feeling in their stomach.

(Timeskip)

Yajin was quiet as he stayed in his meditation state for a whole day. He didn't eat or drink anything.

Daizo was concerned for a bit but he didn't mind much of it as he left with Kahn to their agency.

In the night Yajin finished his shower as Melissa was still showering but he just laid down and looked at the ceiling. He was so deep in thought that he didn't noticed Melissa calling him.

Melissa - Hey, you okay?

Yajin - ...I feel like I failed someone.

Melissa - I doubt you would ever fail but...you seem really disturbed.

He explained everything that happened even how he let Eri go.

Yajin - Eri was in my reach and I had to let her go. But I feel like I took away any hope she had left.

Melissa - I think it's the opposite. You gave her hope. By giving her that energy of you, she would be able to feel your presence and until she sees you again then she'll hold on that hope you gave her.

Yajin stayed silent as both rested in bed but he barely could get any sleep.

(Another Timeskip)

A few days have passed as Yajin didn't change his attitude as he was constantly trying to keep his lock on Eri's energy. However today was different, Yajin, Izuku, Kirishima, Ochaco and Tsuyu had left towards the same place. This was confusing but once they got there, they saw the Big Three.

Inside they walked in as Yajin saw Aizawa, Fatgum, Ryukyu, Gran Torino and many other heroes.

Yajin - I'm guessing they called you last minute?

Aizawa nodded but he told all of them to call him Eraserhead in public.

Ryukyu - We're all here Nighteye. Let's get started.

He walked up and thanked them for the information and that the meeting was about the Shie Hassaikai.

Everyone sat down as they heard the information of Nighteye's investigation. Explaining a villain bust but also the meeting with the League of Villains. Gran Torino even explained that he was called in but he had a bad feeling.

Ochaco asked about the Hero Network but Rock Lock spoke up.

Rock Lock - Does anybody wanna tell me why a bunch of high school kids were invited to this conference. I don't care if they are from U.A. If we have to stop and explain to them everything then we'll never get to the actual plan.

Fatgum however stopped him and introduced himself and even told them about the quirk destroying drug. Tamaki even told them that it did wear off.

Yajin - Wait. Does anyone have a sample?

Fatgum brought out the bullet as he explained that it was already examined but Yajin grabbed the bag and broke it apart.

Quickly taking the drug's liquid as he closed his eyes and what he felt is what infuriated him.

Aizawa even said that his erasure would only cut off the signal to quirks but the bullet completely destroyed the quirk cells.

Ryukyu even mentioned about the drug that made two villains go on a mindless rampage but it increased their power the more angry they got.

Yajin - But that's similar to....a Saiyan.

Nighteye - Hidashi. Explain now.

Yajin - This bullet contains human blood and cells but the energy in the blood...it's very familiar.

His eyes turned red for a moment as Izuku and Mirio remembered someone.

Yajin - Chisaki is using a little girl called Eri. I'm guessing that's her ability. Quirk Removal. I found a drug similar to this...the Beast Drug.

He pulled out his phone as he called Melissa and placed her on speaker.

Yajin - Melissa! Tell me everything you found on the Beast Drug.

Melissa - I was gonna tell you later but I guess now is good. I found the identity of the DNA and you might not like it.

She sent him and image as he played it on the screen and it shocked him.

Everyone was shocked when they saw the images. Yajin's fist clenched but he realized something.

Yajin - Someone was in the battle with All Might and escaped with mine and my brother's DNA.

Nighteye - I'm guessing their using the DNA to make the drugs more dangerous than before.

Yajin nodded as Nighteye brought out a picture of Kai Chisaki.

Nighteye - Their young head. Chisaki, quirk "Overhaul" with this power he can disassemble things and then reassemble them. A quirk that completely lets him break down matter and a bullet that can break down quirks.

This brought a bit of fear in their eyes as they remembered Eri's words.

Nighteye - He's using a little girl called Eri like how Hidashi said but when they encountered her, they noticed bandages around her arm and legs.

Ryukyu - Could he really do something so horrific?

Torino - In a world of Super Humans...it's possible if you think it.

Kirishima - Wait what?

Yajin - He's using her body and making them into bullets.

Kirishima, Ochaco and Tsu were horrified of the thought that a little girl was being used to make weapons.

Nighteye - It's possible that their still in the testing phase.

Yajin - Someone is working with him and giving him my blood.

Fatgum - Just talking about it is enough to make my blood boil. Let's go get this monster!

Rock Lock - Tsk. Would have saved us the trouble if these three amateurs just got the girl away from him.

Aizawa eyes widen as well as Yajin's as he looked at Rock Lock, in the blink of an eye he rushed forward and had him right in the wall as everyone looked to see a furious Yajin.

His eyes were red as he held him close with a smile forming on his face as a fire aura erupted.

Yajin - You believe that you could save her huh?! Remember this...to me you are nothing more but a bug. A worthless waste of a hero. The moment you would leave, you and an entire city would have been destroyed. So remember your place...weakling.

He threw him to the ground as Yajin powered down and the meeting finished.

Yajin - I have her location. So get everything you need and we move out.

Nighteye - We will need a day for a warrant.

Yajin - Fine.

(Timeskip)

Mirko had just arrived back to Japan and she looked at a picture of herself and Yajin smiling.

Mirko - I miss that kid. Let me call him.

She opened her contacts and found his number as she dialed it and she saw his contact picture. She couldn't resist the little smiley face he had.

Yajin - Hey.

Mirko - Hey kid. I just got back, I wanna tell you all about it. Where can we meet up?

Yajin - Right now...it's not a good time.

Mirko - What's up?

Yajin - I'll explain later just meet me at Endeavor's agency. I need to talk to you both.

He hanged up and Mirko had a bad feeling about everything.

(In the Hassaikai base)

Eri laid in bed as she watched the light that Yajin gave her, her body was still trembling but it got calm as the light went towards her and entered her body. Yajin's energy was now part of Eri.

She closed her eyes and tried to fall asleep but she saw something. A red fire but it wasn't one that made her run away or scared. It was a calm fire, she walked towards it and touched it. She felt safe...protected.

She looked up to see the fire form into a figure. Eri couldn't see exactly who it was but all she could see was the figures blue eyes. However she could see the fire turn white as its blue eyes turned red.

Eri woke up to the sound of a door opening as she saw one of the henchmen of Chisaki smiling as he brought another toy for her.

Eri - Please...save me...they're hands...they were warm and soft. I want to...I wanna feel that warm feeling again.
