You'd Kill Me If You Knew

The Plan

"Ready?" Seimei askes Koken who nods and puts a mask on.

The mask in question looked like a mask a child would wear which only showed Koken's eyes but it had been changed slightly to filter out the air only allowing oxygen in and carbon dioxide out.

Seimei walked to the wall in front of her as Koken rooted around in his pocket. She lifted her hand out before running it along down both ways of the wall. Blue flames erupting from her fingertips as she went. She then dragged her fingers across many items of clothing at the back of the store. She walked over to Koken and held out her hand with all fingers exposed and he placed a plaster on her pinky finger.

People in the shop began to scream and rush out at the sight of the blue fire witch was rapidly spreading.

Outside a news team had arrived.

"We are on the scene of a quirk induced fire. People are certain that the fire is the work of the villain Dabi but he is currently in a live interview with police. Which leaves the question. Who is behind this attack? Pro hero Endeavour is at the scene but seems hesitant to go in."

Seimei and Koken had both decided to see what was going on out in the street and were now standing at the doorway of the burning building.

"2 children are stood at the entrance of the building. People are saying that these are the children that have been seen with the League Of Villains."

Seimei stuck her tongue out and ran inside again. Koken glared at the flame hero before following Seimei.

"More heroes have entered the scene to deal with the league."

A chunk of burning wood was flung at Endeavor hitting him on the face.

"STRIKE!" Seimei shouted with her facial expression only showing through her eyes. "Koken your turn."

Another flaming wood block flew out of the door this time hitting the arm of a blond hero setting his costume on fire. The man begin to panic and screamed. The scream was ear piercing and partially defended people in the area.

"Shut up!" Seimei shouted throwing a clothes hanger at the hero's face. "Good shot Koken."

Everyone was shocked at how little expression the children showed on their faces but were fully capable of recognizing the expressions on one another.

The woman with the gas quirk let some off only to have another burning piece of wood thrown out catching her trousers on fire.

"Leave us alone." Seimei called out.

She sees the face of the hero she had talked to yesterday. 

"Did you not tell them what I said. And to add to it all of you being here if very illogical." She said her expression still blank. The TV shop across the road had the channel for really big news stories playing the screen changed to an alert of a break out. "See what did I say. There are at least 5 really big pro heroes here but over there where the heroes are more needed they are not."

"Soon we will be portaled out of this building and thanks to you coming to our small scene, there will no longer be a missing member to the league." Koken spoke calmly as Seimei throws more burning wood at the heroes.

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

The mist cleared and the villains were in the interview room.

"Took you long enough." Dabi said as the police are forced to back away from the group of villains.

Kurogiri portaled them outside and they began walking up the street towards the shop Seimei and Koken were drawing attention to.

"Gonna take these off me?" Dabi asked raising the quirk suppressant cuffs.

"The only way we can is by breaking them and I want to keep them Shigaraki said not even glancing at the cuffs. "Seimei can pick the lock when we get to them."

"Its scary how quickly she learnt to pick locks she's also ridiculously good at it." Twice said.

"My legs hurt can we just portal to the shop?" Toga whined

Shigaraki sighed but nodded and Kurogiri got them to the shop.

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

"Why are you still throwing knifes at us? We've caught everyone so far and thrown them back at you. Also only 2 have missed." Seimei called out from the building throwing the recently caught knife and throwing it at the legs of the heroes.

The purple mist began to form behind them. Shigaraki, Dabi and Kurogiri stepped out. 

"Seimei can you get these off Dabi then we can go back to the base with the others." Shigaraki said.

"Yes a challenge!" Seimei exclaimed her face still unchanging.

She grabbed the handcuffs and found the key hole in the back. She quickly produced a paper clip from her pocket and stretched  it out before inserting it into the key hole. After 2 attempts the first cuff opened she removed the paperclip and unlocked the second first try.

"There." she said bending her paper clip back to normal and placing it in her pocket.

"Koken come on. We have to cook diner too." Dabi said reaching out towards the boy he took it and was lead through the portal.

"Bye. Better luck next time Murder." Seimei said looking directly at Endeavour for the last bit.

She then turned around and walked through the portal followed by Shigaraki and Kurogiri. As the portal cleared the heroes and news cast were shook.

No one can pick the cuff locks bust she did it in a matter of seconds. Let alone her calling Endeavour a murderer. Even the way she showed no emotion on her face but her voice showed more emotion than the average human.

The villains must have done something to her. She had to be affected by at least one quirk. Even her aim was terrifying and even if civilians thought that she missed the main target of her shots they would be wrong. She missed twice or was dodged twice more like. All other shots landed where she had planned. The same went for the boy. But he had to be influenced by something he had taken Dabi's hand without a second thought about it.

One thing crossed the mind of the black haired hero. The children needed to be saved.
