Hc: after so many fights, L just can't fight back anymore. So you have to step in.

This past month had been a hectic one. The tension in the air between L and Light was very very intense. All they did was fight, verbal and physical. They'd go for days without talking to each other then out of nowhere someone would say something that pissed another off and another screaming match and boxing match would start. It had always been left at a tie, someone breaking them up before anything could get too far. And L had always remained as calm as one could be when getting punched in the face. His usual flat tone and matter of fact speech persisted.

But today, was a breaking point. They hadn't spoken in a week, and the tension to finish the last match was high. One wrong move and everything will fall on top of them.

It was eerily quiet, no one dared to speak in case it sparked another fight. But the sound of a computer beeping was what put you on high alert.

L and Light looked up, reading the email that just popped up. Another death, this time definitely linked to Yotsuba, it was painfully obvious.

"That's... not all that discreet..." L mumbled, saving the contents of the email into file.

It was silent for a moment, and in his infinite wisdom fuled by saltiness, Light spoke up.

"Yet another reason I'm not Kira-" he mumbled.

In that moment you could feel the tension break. Immediately L stood up, slamming his hands on the desk and making his chair, slide across the floor. He'd finally been pushed to break his character for the first time.

"You know what Light, I'm not dealing with your fucking bullshit. We all know goddamn well you're Kira and now you're just purposely stirring the pot. YOU'RE A POWER HUNGRY PATHETIC EXCUSE OF A HUMAN BEING AND WASTING EVERYONES TIME- NOW GET OUT!" He screamed.

The taskforce remained frozen, never having heard L swear or speak above an inside level before. He was seething with anger, and in all honesty, it was scary.

"IM WAISTING EVERYONES TIME?! YOU'RE THE ONE MOPING AROUND AND COMPLAINING!" Light snapped back, taking a step forward to look down on L.

L turned to face him, standing up straight to match his height.

"I HAVE A DAMN GOOD SET OF REASONS FOR MOPING AROUND, AT LEAST I AM STILL WORKING. YOU DON'T KNOW THE DEFINITION OF HARD WORK MR 'DADDY IS A COP AND I GOT HANDED THIS ON A SILVER PLATTER'. SOME OF US HAD TO START FROM NOTHING. I HAVE ALL THE RIGHT TO BE EXHAUSTED!"

Light was getting dangerously close, you watched closely ready to jump in when the time was right.

"I don't know hard work? I DON'T KNOW HARD WORK?! YOU THINK BEING AT THE TOP OF JAPANS STUDENT LEADERBOARD IS EASY?" He snapped.

"YOU THINK CONTROLLING THE WHOLE WORLDS JUSTICE SYSTEM IS EASY?" L snapped back.

"OBVIOUSLY SINCE YOU'RE COMPLAINING AND NOT DOING YOUR DAMN JOB!"

L was tense, holding back the urge to deck Light so hard his nose broke.

"IM DOING MY JOB, YOU'RE THE ONE MAKING IT HARD BY STARTING SHIT AND KILLING ALL THOSE INNOCENT PEOPLE!"

And finally the stand off broke, in the blink of an eye,  Light lunged at L. L immediately put his hands up to block the punch and when Light made contact he grabbed his wrist and twisted it, not afraid to break his wrist. But Light fought dirty, kneeing him in the gut and sending L doubling over. L swept his foot under Lights to knock him down, sending the both of them to the floor. No one stepped in, this was the most violent they'd gotten and they didn't know how to react. You were ready to, but needed the opportunity to. The right position to.

Light grabbed L's shirt and tried to pull him down, L grabbed his arms and tried to pull him off, kneeling on his gut to try and wind him. But L was at a disadvantage. He was exhausted. He hadn't slept in days, the previous fights made him ache and since he was skinnier and lighter than his opponent it made him easier to take down. Light kicked him off, sending him back and skidding into the office chairs. Becker he could get up Light and pounced on him, grabbed him by the hair and began to smash his head into the ground. L cried out, having the back of his head hit the chair and the front hit the ground. He didn't fight back, he couldn't, his muscles ached and he couldn't get back up.

This was it, this was your chance. You were protective of L that's for sure, so when you started to see blood against the floor where Light was smashing him, you saw red. This was the perfect position for him to be in as well. You got up, marched up behind him and with all your might you draw you leg back, kicking him upside the head and making him fall off L. The sound of your heeled boot hit his head was satisfying, leather against someone's skull made a loud thump. He screamed out in pain but before he could get back up to fight you, you stepped on his neck, hard. He coughed, needing the air.

The taskforce didn't step in, they hired you specifically because you could get violent when needed. They knew to stay out of it.

"ARE YOU FUCKING KIDDING ME YAGAMI!" You screeched, stomping harder on the 'fucking'.

He just kept coughing for air as L lay hopeless and weak on the floor blood dripping from his mouth and tears in his eyes.

"YOU HAVE TO GO AND MAKE SNIDE REMARKS DON'T YOU. YOU ABSOLUTE WASTE OF HUMAN SPACE. I FUCKING HOPE KIRA KILLS YOU IF YOU REALLY ARE'T HIM AS YOU SAY"

With one final burst of anger, you leaned down and smacked him so hard a red handprint ended up on his face.

"Fucking pathetic, and you call yourself a god..."

You walked over to L, lifting him into your arms carefully. He whined in pain, using the last of his energy to cling to you for dear life.

"Shhh... it's ok. You didn't start this one" you whispered, loud enough for him to hear.

You shot Light a death glare as you walked out the room with the injured detective. Taking him into his floor that you technically weren't allowed on and locking the door. You were worried, there was no way that much blood should be coming from someone's mouth...

Placing him on the counter of the bathroom he leaned against the wall and just silently sobbed at the sharp pain in his head.

"Calm down sweetheart, I'll be back"

You rushed out and grabbed a role of paper towels, an ice pack, some bandaids and pain killer. Coming back on you immediately tried to stop the bleeding buy grabbing a wad of paper towels and telling him to bite down on it. The blood from his mouth stained his white shirt and dripped down his neck, with a wet paper towel you did the best to wipe it all up. You got him to lean the back of his head against the ice pack so it stayed up between the wall and his head. Cleaning all the bloodied wounds and finding a few cuts you placed bandaids on his cheek, chin and forehead. Bruising had started to form over his right eye, cheeks and chin. His wrists showed hand prints too. The back of his head was probably bruised too but his hair just covered it all.

When you pulled the bloodied tissues form his mouth you got a look at his lips. Apart from a small cut they seemed fine. Just a little swollen. You gently ran your fingers across his skin to examine the cut, making him flinch.

"Ow..." he mumbled weakly.

That when you spotted it. And dreaded the outcome.

"Open your mouth"

Confused, he did. You were right, one of his front teeth, on the right, was missing. Light fucking hit him so hard he knocked a tooth out.

"Shit... he's fucking knocked your tooth out" you said.

Dread filled L's eyes and he turned to he mirror and saw it for himself. That would explain why his mouth was bleeding then... that's were he had the most pain, his mouth and the back of his head. For good reason too.

"Hey, it'll be ok. Take some pain killers and have some water and take a quick shower and sit down to calm down for a while ok?" You said.

He nodded and you pulled him off the counter.

"Plus, you'll still be cute as hell even with a missing tooth" you smiled.

He smiled back, letting you kiss over one of his bandaids and gently rub his arm. You handed him a pain killer pill and the nearest towel.

"Take this, drink some water and take a shower. I'll go deal with the others"

"You'll come back though?" He asked.

"Of course, gotta cuddle my injured baby who didn't do anything wrong" you replied.

With that you left him to clean himself up some more and marched down to the scene of the crime. The others had all moved into another room. Probably to help Light. Just as you suspected, in the small pool of blood was L's missing tooth. You picked it up, turning to find the taskforce.

They were in the kitchen, trying to stop Lights forehead bleeding. When you walked in they all looked at you. More in fear than anger. But lights dad was definitely not too pleased you kicked his son. Although he knew Light did start it.

"Listen, Mr Yagami. I know you're probably not too pleased I kicked your baby but I thought I'd let you know that Mr anger issues over here has knocked out one of L's teeth" you said, holding it up.

The taskforce looked at it in shock. Bloodied and chipped. You continued.

"Other than that, he's ok. Maybe a little dizzy from the head blows and covered in cuts and bruises, but ok"

Mr Yagami sighed, now having to deal with the fact his son straight up broke another persons tooth off. Light looked a mix of scared, dazed and pleased with himself. Sick bastard. You gave him another death glare and went downstairs to find Watari who was probably working and missed the whole thing. You were correct since you found him ordering L's beloved strawberry shortcakes in.

"Watari" you said.

He turned to face you.

"What brings you here miss (l/n)?" He replied.

"L and Light got into another fight. A very very violent one, Light started it, of course. But L got very worked up and emotional, and ended up with light smashing his head into the ground and a chair, and..."

You held out your hand with his broken off tooth.

"Knocked out his tooth"

"Is that so..."

Watari was always calm, and had that 'nice old man' personality. But you could tell from his tone he was holding back a lot of anger. L was his son type figure after all.

"I kicked Light upside the head and stomped on his throat to get him off L. He's fine just bloody. And L's ok too, just missing a tooth and has a couple cuts and bruises. I think it's best they stay away from each other for a while, and I'll stay with L to make sure he's ok" you explained.

"I see, I guess I'll book a doctors trip just to make sure that tooth doesn't cause any problems. I'm guessing the fight scene is a mess?" Watari replied.

"Yeah, blood on the floor and chairs knocked over in the monitor room"

"I see, I'll handle that. Thank you for stepping in"

"It's fine, just thought you'd like to know"

After that conversation wrapped up you went back upstairs to find L sitting on the sofa wearing an oversized hoodie and wrapped in a blanket. Still dazed and shaken from the whole thing. You knew that hoodie, it was his 'I'm sad and tired' hoodie. Like a comfort hoodie probably. He'd never gotten that violent before.

"Hey, I found you tooth. And talked to Watari"

You sat down next to him and handed him his missing tooth. He looked down at it and instinctively tried to feel the gap in this teeth with his tongue, it felt weird.

"You gonna keep it?" You asked.

"Why would I?"

"Some people do"

"No, the gap is reminder enough"

He placed it on the coffee table for the time being and leaned his head on your shoulder.

"Feel better? The pain killers working? Watari is booking a doctors appointment to look at that tooth" You asked.

"Yeah... thanks for stepping in. I'm so tired and sick of all this I couldn't even pick my arms up anymore" he sighed.

"After this many bashed and such hard work I'd be like that too. Don't beat yourself up over it..."

"Light already did that..."

"You know what I mean" you giggled.

He smiled and snuggled up to you.

"I expect you to get some sleep tonight" you said.

"I will, I'm exhausted"

"You better. Don't worry about anything. I'll always protect you. I would've jumped in sooner but if I caught Light still on guard he'd beat me up too"

"I get it... you still jumped in, so it doesn't matter. I'm alive, sore and missing a tooth but alive"

You wrapped your arms around him and pulled him into a hug.

"You'll be ok, just rest and stay away from bitchtits Yagami for a while" you said.

He snickered at the name and smiled, kissing your cheek.

"Thank you, I love you" he said.

"I love you too, and you know what? A gap in your teeth isn't so bad, you can stick straws through it now"

"...holy shit you're right"
