Living on the second story of an apartment complex, the last thing you'd see is a girl, seemingly the same age as our little broccoli boi, coming crashing through the window with a large knife aimed straight at his gut. Just based on the pure surprise of the event, Izuku launched off the couch and onto the floor, and turned just in time to see the armed girl plunge the large knife through a pillow and the couch fabric, and was able to get a good look at his assailant.

She had messy blonde hair tied in a bun, with a worn out uniform from a school the boy couldn't identify. Her entire body seemed small, yet had power for her to pull off probably difficult stunts for himself. Her eyes, once she had turned to face where he had landed from his dodge, screamed blood and death, with a hint of lust. If anything, Izuku became very terrified thinking about what she was about to do to him.

"Izuku are you okay? What was that?"

Oh shit, his MOM was here too.

"It sounded li-" Inko cut herself off as she re-entered the living room, to take in what events had occurred. An unknown armed girl was on their couch with the handle of something embedded into it, with Izuku staring with fear at the sight.

"Who are you? What are you attacking my son?" Inko didn't know who this girl was, but the fact she had broken her window and stabbed her couch in an attempt to injure her son, especially after hearing Izuku was almost attacked earlier, she was scared to say the least.

But her anger was dominating all other emotions right now.

Izuku was about to piss himself. His mother spoke with an unheard tone. One that dripped anger. She was normally timid, shy, and cried just as much as him sometimes. She was never truly angry.

But she was now.

"Awww, mommy's all upset~." The assailant song-spoke. She had pulled the knife out and stood on the couch, matching Inko's height, which was terrifying. Inko stood at around a 170 cm, so for a girl this young to match her height?

Oh no.

"I would've knocked, but the windows are more fun, ya'know?" She answered sadistically.

The Midoriya's were shocked. After the event she had caused, she was making jokes.

"As for why I'm here, I'm here to avenge Sludge and take your son's head~ ;)" She gained a sadistic grin on her face to match her dialect as she turned to the boy, who was still stuck on the ground.

"But don't worry." She looked over her shoulder at the fuming mother. "I'll make it quick!"

Finishing her response, she dove at Izuku, knife swinging at his neck. He raised his arms to try to grab her wrist.

He missed.

But so had she.

He felt a cut appear just before his left shoulder, but she had been pulled off of him by an unknown force. He scrambled up and ran to the door of his room, but turned to see what had happened.

Turned out his mother's power could pull much larger objects when she was mad.

...and she was Furious.

"Boss said you'd get in the way." She said annoyingly, her expression turning from playful to serious. "Guess I'll deal with you now before I take your son!" The girl got back up and began to attack the mother in anger, but Inko was prepared. She zipped a frying pan into her hand, and did her best to defend, getting an occasional scratch.

"MOM!" Izuku screamed at her, panicking at the scene. Before he could run to her aid, his mother yelled with a volume he'd never heard her use. Not even in her arguments with his father.

"Izuku, RUN! She's after you, get away from here! I'll be alright, I'll come find you when I'm done!" She had tears in her eyes, making it a little difficult to see the girls attacks. She just barely saw her sons state, but blinked them away as she focused on taking out the girl. She couldn't lose to her, because the state Izuku was in would only get worse.

"You won't get the chance!" The girl screamed, continuing the onslaught.

"But Mo-"

"NO BUTS, IZUKU! RUN!" She cut him off, putting force into her words.

Izuku couldn't believe what he was hearing, but he ran into his room and slammed the door shut, and locked it. He grabbed his shoes with his right, and tried to open his bedroom window with his left, only he couldn't. Due to the amount of adrenaline running through his body, he had assumed the cut he had received from the girl was just that. A cut. But it was so much worse.

He fell onto his back and found out why he couldn't feel his left arm.

He had left it in the living room.

( . . . )

Izuku immediately flung open his closet and grabbed an old, worn out shirt, and wrapped it around his stub of an arm. Grabbing his belt he wore when his mom had bought him to wear with fancy clothes, he tightly wrapped it around the shirt, creating a homemade turning kit. The blood was still coming, but slower now. He had extended his time for survival, but without hospital care, he could get an infection, or plainly bleed out. He threw on his signature red boots, and jumped out the window. He hit the ground hard, being on the second story didn't exactly help. He pulled himself off the ground and ran. He knew the fastest route to the hospital, and ran full speed there. He'd rather run for the cops, and even considered Bakugo, but he knew even he couldn't win. And he couldn't risk the Bakugo's getting hurt like him.

The police were further than medical, so it was the only option left.

As much as he hated it, he had to trust his mother. He should've stayed and tried to help, but he got her message she never got to say out loud.

'Without a power, and not knowing what hers is if she has one, you wouldn't be able to save me, less yourself. Let your mother be your hero, this time, okay?'

The tears kept coming as he ran. He kept thinking about all the times his mother had been there for him, and how he couldn't always be there for her. Especially after the divorce. He hated it. He didn't need her to be his hero this one time, or ever.

Because she already, and always was, and will be.

She was a greater hero than All Might, after all.

( . . . )

Inko had managed to disarm the girl, and take her on the defensive. A few good hits with the pan had left large bruises, but she wouldn't go down. After she saw Izuku leave, she knew what it would come down to. The girl would become rushed to kill her quickly to pursue her son, so she waited till the perfect time. Before she grabbed the pan, she took a chef's knife and hid it, tucked between her pants and body, under her shirt. She waited for her opening, and it took a while, but it came. The girl tried to stab her with nothing in her hand, and Inko smacked and held the pan across her face. She reached around her back, grabbed the knife, and slid it into the girl's gut.

She managed, at least she thought, to miss the girls organs so she wouldn't die, but so she'd become incapacitated.

What she hadn't expected was for the girl to have the same idea.

As she looked down at the chef's knife sticking out of the gut of the girl, she found a second knife, buried to the hilt in her chest.

"Good plan, mommy!" She rasped out. Somehow, she still had a lively look to her, even after fighting for a unknown time, then getting stabbed. "Unfortunately, I could see it coming a mile away, seeing as you always kept your right hand close to your hip, like you were going to grab something behind you. And I think I hit a more important organ, too!" The crazy child announced.

They both fell to the floor, Inko breathing hard. She knew the blade had to stay in to stop from bleeding out, but had to come out or she'd die or infection. The young girl, however, got up, pulled the knife out of her without even flinching, and began searching for something. Inko watched as she walked over to the kitchen and seemingly find her treasure, which turned out to be a first aid kit, and began cleaning herself. Inko stared in horror from her spot on the floor, tightly keeping the knife in place, as her attacker patched herself up, and stashed the blades in her uniform.

"It was a nice fight mommy! But I have to go see your son now. I'm afraid an arm won't cut it. Maybe his brain would~"

"He's gone, you bitch." Inko spat back, trying to keep from going unconscious. This was bad. Izuku could make it to the hospital, but without an arm? She wasn't so sure. Maybe it was the loss of blood that made her mind foggy. No, that's definitely what it was. Having a knife either by or in your heart wasn't the best condition to be in.

"He'll go to the hospital, and I know a faster route. Plus, I know where he'll take a break to fix his 'bandage'." She said as she pulled her phone and showed a feed of Izuku's location.

"And he won't run from me," She continued, filling a vial of Inko's blood puddle forming on the floor, stashing it, then licking more with her tongue.

Inko's dimming green eyes stared at the girls' red ones, until her skin began to bubble and change. Soon, the blonde-haired, red-eyed demon disappeared, and a copy of Inko stood up, looking down at the dying Midoriya.

"Because who runs from their own mother after they defeated a villain?"
