My Hero Academia 7 (mha x oc)

8- Wounded Hero, Burning Bright and True

"You... what you hear about fear, strength, weakness, being special... I don't care about all that" Kyoka says as she grits her teeth, "I don't care! It's your fault that my friends are crying! It's your fault that my best friend is fighting to save her brother who you ruined!" she says as she sends out her now only one speaker, "Heartbeat Surround... Legato!" she says as she sends even stronger sound waves towards All For One. 

"Motivation, behaviour, ability... these are all at the level of someone weak" All For One says as Koko holds onto Hawks who is struggling to keep upright due to his injuries, "it's not enough! Your power is overwhelming lacking!" he says as he tries to counter the attack, only for something to stop him. 

--- inside All For One's mind ---

All For One looks back as he sees the apparitions of the users of Quirks he's previously stolen holding him back. 

Is this the will of the Quirks I've stolen until now? No way... Not even New Order was... are you saying they got me... with weakness of the weak? 

All For One asks with a smile. 

--- in reality ---

"Hawks! Koko!" Kyoka yells as she ignores the pain and blood loss of her injury. 

The first hit... the second and third hits... I've hit the same place continuously to spread the wound. Bit by bit... Sound Wave Vibration Enhanced... Flight Feather Blade!

Hawks says as he uses Kyoka's sound waves to enhance the strength and speed of his attack, hitting his blades against All For One's mask for a fourth time. The front part of the mask falls off on the upper part, exposing where All For One's eyes would be. 

"Tsukuyomi!" Kyoka says as she looks at Tokoyami who let her go, Dark Shadow holding her up, "Dark Shadow, this is our chance!" she says as she covers herself and Dark Shadow from the sunlight, "okay, see you later!" she says as she jumps off of Dark Shadow, Dark Shadow returning to Tokoyami who wraps a black cloth around his fist. 

Kyoka sends her sound waves towards All For One as Hawks' feathers keep her afloat again. 

Hawks' current power isn't enough to inflict a fatal blow... in that case... 

Tokoyami says as he puts Dark Shadow's fist over his, the cloth ripping. 

"Black Abyss... Ragnarok: Fleeting Blow!" Tokoyami says as he takes off a major part of All For One's mask, "Koko, now!". 

Koko flies in as she puts her hands up in front of her, using her telekinesis to break the mask apart bit by bit before nothing is left of the mask. 

"Kyoka, let me cauterise your wound" Koko says as she flies over to Kyoka. 

"No" Kyoka says as she ties a cloth around her head, "Hawks said that you can't use your Quirks, so don't. I don't know why, but don't do it, Koko". 

"I'm fine, Kyoka" Koko says with a reassuring smile. 

"You won't even tell your friends you're dying? Koko, they deserve the truth" Hawks says as he flies over, the four of them regrouping, "All For One is slowly killing Koko from the inside. Physically, she may look well, but every time she uses a Quirk, it hurts her". 

"Koko..." Tokoyami says as he looks at her. 

"Please don't tell anyone. Especially Izuku, or Katsuki, or Shoto" Koko says as she looks at Kyoka and Tokoyami, "I'll tell them. Just not until I know I'm near". 

"You thought they were just stalling for time, didn't you?" Hawks says as he turns to look at All For One, "but bugs are actually... pretty annoying!".

I needed to dodge the attack just now. But I realised this too late. Ever since I lost most of my senses, I look for Sensory Quirks that could detect vibrations and infrared radiation. With those, I'm able to perceive much more than an ordinary human. If it was just that girl's immature sound, it wouldn't have been an obstacle. This cause was the Quirks' rebelling. This never happened before. Does this vulnerability stem from using copies? My authority over them is weaker than when I had the originals!
