Heroic at Heart (MHA x OC)

(4- Infiltration

3rd Person POV
'You cannot be serious, Tomura Shigaraki!'
'So what? I need her to overcome this stupid thing for the plan!'
'So you killed the man who insulted her but you are keeping the man who physically harmed her?! That is outrageous Tomura!'
'That slimy creature insulted my masterpiece, my work of art. Scream didn't harm her, he strengthened her.'
'You are insane.'
'Only noticed now?'
The muffled voices were making their way to a young girl's ears as she walked down the hall towards these voices.
'So I'm just another toy to you, Dad?'
Both men looked up as the girl they were discussing spoke.
'Really?'
Niko looked at Shigaraki with a cold glare, which he returned.
'You aren't like normal kids, Niko. People would honestly kill just to be able to be friends with you. But you don't need friends, villains don't have friends. You have allies, and family like me and Kurogiri. But that's where the line of friendliness cuts off. Friends aren't there for you, they are leeches trying to gain from your power. To a friend, you are a toy. But not to your family. So stick with family. However, betray your family once, and you will never be forgiven. Remember that, Galaxy.'
With that, Shigaraki left the room. Niko looked at Kurogiri and the unconscious man, Kakumyo Hayashi. She could only say three words.
'What the fuck?'
———————————
Three days had passed. Hayashi or 'Scream' as he preferred to be called by, was now training with Niko to help her get over (as Shigaraki put it) her sensitivity to noise. All the training was doing however was weakening Niko, which angered Shigaraki. He pulled her aside one day during endurance training and told her his plan that was to take place the next day. She agreed and they called a meeting in the bar, where Shigaraki would explain to everyone their roles.
'I was scouting the school today. Ever since the media found out All Might teaches at UA, they've been swarming the gate like flies attracted to shit.'
Shigaraki spat on the ground. Hayashi looked slightly on edge. Niko was messing around with a beer bottle, smirking while looking at Kurogiri who was watching her with an aura of disapproval.
'So I was thinking. Me n' Scream can go to the gate, Scream can pose as the media and I'll act as his cameraman for example. We get close enough to the gate, I'll Decay it using my quirk. Once the media swarms onto the campus, setting off the alarms, me n' Scream will come back to base. Here,' Shigaraki said, pointing to the ground he stood on. Niko was gazing at the blacked-out window while fiddling with the lid of the beer bottle, clearly not paying attention. Kurogiri cleared his throat, indicating to Scream to take the bottle from her. Scream hesitantly obliged as Shigaraki sat back, contemplating his plan so far. Scream snatched the bottle from Niko, which snapped her out of her daydream. She immediately tackled Hayashi, pinning him to the ground. She sighed and reached for the bottle which was laying on the floor, only for it to be teleported by Kurogiri. Niko stared at Kurogiri with an outraged look.

'YOU BASTARD! GIVE THAT BA-'

'SHUT THE FUCK UP! GET UP KID!'

Shigaraki grabbed Niko by the collar of her filthy torn grey shirt and hoisted her onto a barstool. Kurogiri helped Hayashi to get up as Shigaraki hit Niko across the face.

'You damn junkie, I would decay that smirk off your face if I didn't need you for this.'

Niko smiled psychotically and Shigaraki sighed in annoyance before returning to his seat. Hayashi eyed Niko's strange facial expressions nervously, while Kurogiri just sat quietly but secretly disappointed in Niko's relapsing behaviour.

'Foggy will teleport the bitch into UA. The alarms will be going off because of the media anyway so security ain't an issue. Just find a way into the staff room, get the schedule for class 1-A and 1-B. It seems that All Might favours class 1-A however so make that a priority. Class B is only an additional piece of information. Got it?'
Kurogiri and Niko nodded, Kurogiri looking serious while Niko looked slightly distraught, her psychotic smile disappeared from her face.
Hayashi cleared his throat before standing up. Shigaraki looked at him warily, while Niko glared at him; she hadn't forgiven him for taking the beer off of her.
