Katsumi: THE HELL ARE YOU DOING?! LET GO OF ME!

SMACK*

Several people pin her onto the ground as she tries to get them off-

CUFF*

She was cuffed and promptly kicked across the face, breaking her nose as someone grabs her face.
???: So this is the girl who drove my son to kill himself...

???2: SHE KILLED MY FATHER AT THE USJ!

A crowd of people roared for Katsuki's execution as she was dragged further into the alleyway-

???: BRAT! GET OUT OF HERE!

Katsumi: You...WHAT THE HELL ARE YOU DOING HERE?!

Ojiro: What? I'm just looking around. Oh...I see there are many people mad at you.

Katsumi: GET THESE EXTRAS OFF OF ME!
Ojiro: No. I don't think so. The Todoroki and Bakugou deserved to die.

Katsumi looked enraged but a horrified look appeared on her face as Ojiro gives the others a look.
Ojiro: I do not condone senseless violence, but I won't be able to win against you all. I'll just...walk to the nearest police station or hero. Probably will take 15 minutes, 25 if I take my SWEET time. Maybe more...I think I forgot where it was.

???:...Smart kid.

Katsumi: 'W-WHY CAN'T I USE MY QUIRK?!' *beg* W-Wait hold on!

???3: Don't worry princess. *grin* We'll be having PLENTY OF fun.

???5: Consider this payback for those times in Highschool you little shithead.

Ojiro puts on headphones as he ignores the screams of pain and the crunching of bones as they beat her to death.

Later

Aizawa: Footage for Katsuki's death?

Naomasa:...Yes.

Inko: L-Let's see then.

Many were worried, but Mitsuki wanted some closure, wanted to see what her idiot son had done to warrant Izuku to kill him.

CRACK*

Izuku: Don't come back Katsuki. You won't win. Not in a million years. Please...just leave me alone.

Aizawa: Who sent him?

Toshinori: I...I think I did.

Aizawa: Toshinori you do realize-

Toshinori: I-I just thought they could reconcile. I-

Naomasa: Toshinori you can't just forgive 14 years of bullying. MOTHERFUCKER THEY LITERALLY TORTURED IZUKU AND KILLED OTHERS! EVEN YOUR OWN DAMN DAUGHTER! CAN'T YOU ACCEPT THAT?!

Toshinori and Inko shrunk as the video rolls forward.

Chiyo: You big oaf. Just shut up and watch-

Katsuki: Hehe...I knew it. You've always been a coward you damn deku. Just like that deaf bitch.

Everyone: 'Deaf bitch?'
Katsuki: I never told you about why she was in a coma Huh. Well that's because I pushed that damn bitch into that car!

Toshinori: Wait...WHAT?!

Aizawa: Why are you surprised?

Katsuki: It's like a match made in heaven! Too quirkless losers thinking they can do whatever they want! Had to teach her a damn lesson with the others!

They were horrified as Katsuki revealed more of what he had done, the atrocities he did as Izuku walks towards him.

Katsuki: *grin* Fucking quirkless bitch. She should've died. YOU should've died years ago! Too bad she was a damn slut. I WISH YOU COULD'VE BEEN THERE TO HEAR HER SCREAM! THAT'S WHAT SHE GETS FOR GETTING IN MY WAY!

Inko: He...*horrified* H-He and the others.

Katsuki: I DARE TO HIT ME YOU DAMN DEKU! HIT ME! I'LL JUST KILL YOU LATER WHEN I HAVE THE CHANCE! I'LL GO AFTER THOSE TWO LITTLE GIRLS AND THAT DAMN FURRY TOO FOR ASSOCIATING WITH YOUR QUIRKLESS ASS-

Izuku: I've HAD ENOUGH!

CRACK*

They were all shocked as Izuku swiftly punches Katsuki, pushing him onto the ground before pummeling his face from above.

Izuku: I DON'T CARE IF YOU AND YOUR FRIENDS INSULT ME, BULLY ME, TELL ME TO JUMP OFF A ROOFTOP!

CRACK*

Izuku: BUT YOU NEVER, EVER THREATEN MY DAUGHTER AND GIRLFRIENDS!

Inko: I-Izuku...

Aizawa: Wait...he's not stopping.

They were horrified to see Izuku's face filled with utter rage as blood begins flying everywhere with each punch that battered Katsuki.

Izuku: YOU HAVE NO IDEA WHAT I'VE BEEN THROUGH! WHAT HELL I HAD TO GO THROUGH TO GET TO THIS DAMN POINT!

BOOM*

Izuku: HOW MUCH ANGER I HAVE TO HOLD BACK! HOW MUCH I'VE SUFFERED BECAUSE OF YOU!

CRACK*

Izuku shatters his teeth and they were forced to watch as he continues to punch Katsuki even with the blood covering his torso.

Inko: P-Please stop.

Izuku: NO ONE!

CRACK*

Aizawa: To think you held this much anger in.

Izuku: NOT YOU, NOT KATSUMI

CRACK*

Toshinori: M-My boy...

Izuku: NOT IZUMI, NOT THE TODOROKIS!

CRACK*

Izuku: OR ANYONE!

CRACK*

Mic: Little listener...

Izuku: WILL EVER HURT ME!

CRACK*

Izuku: OR MY FRIENDS!

CRACK*

Izuku: OR ANYONE I LOVE!

CRACK*

Katsuki at this point was barely moving yet Izuku continues to punch through bone and flesh as he screams at the dying boy.

Izuku: EVER! AGAIN!

They hear the primal scream from Izuku as he kills Katsuki with a slam of both his fists that shattered his entire head, brains and blood splattered everywhere and the clip cuts off.

Naomasa: No, he's not in trouble. Through his phone we've confirmed his intentions to kill Izuku and even his girlfriends and kids for revenge. I do not condone murder, but if Izuku didn't kill him he and his friends would've all been in grave danger. It is not surprising however that he snapped like that. No, he's not going to be charged.

Inko was crying, and Toshinori was left in a state of regret as Mitsuki asks Naomasa about her daughter.

Naomasa: Both her arms were crushed and torn off. About every bone in her body was broken, and it appears she had died from internal decapitation that was rather swift. It is a tragedy...but they had it coming sooner or later.

They were left in somber silence...and Mitsuki was happy on the inside and Izuku from afar rejoiced, knowing another cant torment anyone any longer.
AFO: 'The All Might brat though...she's becoming unstable. That's a problem by itself. I'll have to personally deal with her myself if Toshinori won't correct him.'

Toshinori2: 'Yes she is not remorseful at all. She has to be corrected or else...'
