"Explosions"

Yajin crashed onto the ground as he looked up to see a figure in the smoke. The figures eyes were green and Yajin stood up as he got ready for the fight.

(Earlier that day)

Yajin was inside the agency room of Endeavor with Mirko as all three were sitting down.

Mirko - Tell me kid, what's going on?

Endeavor - I would like to know as well.

Yajin - Alright. There is a criminal by the name of Kai Chisaki of the Shie Hassaikai. Nighteye and many other agencies are going to investigate his hideout but the worst thing is....he's creating Quirk Removing and Quirk Improvement bullets...using human blood.

Endeavor - Did you identify who?

Yajin - The Quirk Removing bullet is created by the quirk of a little girl named Eri. While the others are using...my blood as well as my brother's.

They were shocked of the information they had just received and they knew the danger for both but especially Yajin's Saiyan blood being able to improve.

Endeavor - I'm guessing this is even worse than Trigger?

Yajin nodded as they stood up and told him that they wanted to help and take them down. Yajin smiled as he walked out and watched the moon but all he could see was Eri's eyes.

Yajin - I promise...I'll save you.

Endeavor - Hidashi, I think have something left I can teach you. It's a risky move but I'm sure you'll be able to master it quickly.

Yajin - Anything could help.

(Day of the Heist)

Yajin had finished contacting Mirko and Endeavor for them to stay in their spots as everyone else would fight ahead.

Kirishima - Yajin. Are Wagashi and Daizo joining us?

Yajin - No. They're with Edgeshot on another mission. I'm not expecting them to show up.

Aizawa - Remember, you need to be calm and not be rash.

Yajin - I know. Hey Kirishima, do you remember what we talked about?

Kirishima - Yeah. I'll use that for a last resort.

Both nodded as the police and heroes went to the Hassaikai base and everyone separated away from Yajin as he was gonna ring the buzzer but quickly a giant man bursted as he sent a punch at Yajin.

The force of the punch was strong enough that it destroyed a part of the street behind Yajin.

Rikiya - Who are you? It's too early for visitors.

Uravity - Goku!

The smoke cleared as the heroes saw Yajin standing there completely fine. He looked up to Rikiya with a serious look on his face.

Goku - Is that all you got?

This shocked the giant as Yajin grabbed his fist slowly as his eyes glowed red.

Goku - Okay then, guess it's my turn.

In the blink of an eye, he vanished and kicked Rikiya's gut, with a roar Yajin pushed the giant towards the street as he was down but still conscious.

Ryukyu - Goku, stand down! The Ryukyu Agency will handle him!

Yajin nodded as he looked at Ochaco and Tsu with a trusting look. He ran with Izuku and Kirishima, side by side.

Yajin/Izuku/Mirio - Eri. We're going to save you.

Most of the police force and the remaining heroes were taking care of the many Hassaikai members not allowing them to pass. But luckily few heroes and cops were able to enter.

Right when they entered the base's doors, Yajin went to a wall and hit it twice. This signal was sent to Mirko as her ears got the signal and both her and Endeavor went towards the base.

Nighteye - Goku, I need a location.

Goku - Here!

Quickly punching through the wall, Yajin was able to locate the secret passage as more Hassaikai members appeared but easily fell when Yajin took them down.

Goku - Deku, Nighteye. Here.

He gave them a device as it was a tracker to Yajin telling them if they ever get separated then to just follow his signal.

The remaining forces went down the underground area only to find a dead end. Mirio used his Permeation to see behind the wall and he confirmed that it was safe to pass by.

Izuku and Kirishima used their quirks to break the wall down, quickly all of them ran ahead. However one of the members "Joi Irinaka" used a performance enhancer to move around the area like a trampoline.

Goku - What the hell?

Fatgum - This is Joi Irinaka's quirk "Mimic" he can move any surface to his control.

Yajin and Mirio went on ahead telling the others that they need to keep moving and not give them the chance to strike.

Mimic used his quirk and got all the heroes and officers to the lower levels. Once they landed, they were greeted by Toya Setsuno, Yu Hojo & Soramitsu Tabe. Three of the Eight Bullets. Fatgum volunteered to fight however Amajiki took the responsibility and fought alone.

Yajin kept running as he felt the energy move to the left as he split from Mirio and went towards a shortcut.

Mimic was able to confuse him as he got him in a room but Yajin looked inside.

He saw a tape recorder as he grabbed it and played it.

Chisaki - Log Date: Day 354. We've successfully reached a breakthrough with the quirk removal bullets. Thanks to Eri's blood we were able to retract the quirk and reverse the quirk gene and clear it. However currently we are still on the half stage. The bullets remove the quirk for over a long time but it seems it's not permanent. Yet. Eri is a precious little curse that will be the cure to humanity. Even if I have to constantly break her down and fix her...it's a choice that I have no regrets in. Just as subject two.

Not wanting to hear more Yajin crushed the recorder to nothing. He picked up a small vial of blood as he grabbed a nearby bag and placed all of the chemicals and blood and even formulas inside the bag.

Goku - Endeavor, Mirko. Come in.

Endeavor - We're about to head inside.

Goku - Don't. There is a quirk user who is moving the underground area all around. So it's almost impossible for anyone to come in. But I need you guys to be ready when I give a signal. Just help the other heroes apprehend the others on top.

Mirko - Alright kid. Just be careful.

Goku - You know me.

Mirko - My point exactly.

He smiled as he left the bag there and hid it inside a box. Quickly going back to Eri's location. However he stopped when he felt something behind him.

Goku - No...it can't be.

??? - It is darling. Soon I will play my turn.

Goku - you're thinking you have all the pieces right where you wanted them?

??? - There are so many moves I've yet to play.

He turned around to see who he was talking to.

Goku - Niara.

Niara - It's been so long Yajin Hidashi. My true love.

Goku - I stopped loving you when you killed my friends...our friends.

Niara - They we're worthy sacrifices to our ideal world.

Goku - Your world, not mine. How did you escape?

Niara - Those fools couldn't hold me forever. So I heard you were loving someone else.

Goku - I'm happy with her.

Niara - And yet I can't seem to stop being attracted to you. I've always wanted you and you with me. You know that.

Goku - I put those feelings away and burned them. So right now...the only feeling I have for you is hate.

Niara walked closer as her wings disappeared and she caressed her hand on Yajin.

Niara - I can tell darling.

She leaned in and he just held her away.

Niara - Hmph. Worth a try. I've come to deliver a message. You're fight with DeVoe is coming sooner than before and you will fall along with this city. But you can join me and we can turn this entire world to your royal kingdom.

Goku - I never want that. You will never get me to join you.

Niara - I'm not so sure. Like I said, there are so many moves I've yet to play.

Goku - You should've stayed buried.

Rushing right at her, Yajin went for a strong punch however he just punched through a fire as the shockwave destroyed the nearby wall.

Niara - I'll see you soon my love.

Grabbing his neck as she used her other arm and delivered a kiss to the Saiyan as he was just as shocked but he backed away and got on his guard. However she was gone with no trance of her anywhere.

Goku - Damn. I've got too many problems as it is.

He ran towards Eri's location as he sped up wanting to end this as quickly as he can.

With the other heroes, Mimic was able to separate Fatgum and Kirishima as they were put with Kendo Rappa and Hekiji Tengai.

Red Riot - Time to fight.
