Dear god why do I keep making more stories?
This is a bad idea.
Oh well.
Alright, I've had the idea for a cross over like this for awhile, and finally decided to do it. I don't have much planned out, but that's how just about all of my stories start.
So uh... Get ready for... Whatever this is.
"A bad idea?"
Yeah, yeah. Something like that. Thank you, random voice that only exists for the sake of this joke.
So uh... Here we go.

A dark room. Illuminated by one TV screen.
"... Monsters..?" He pulled at his bottom lip as he watched the breaking news report.
"Mount Ebott... They came from Mount Ebott..." How did he know that?
"Hm?" Another asked, standing with his back straight, next to the couch the other crouched on.
"They seemed to have come from Mount Ebott, and upon questioning it seems-"
"That they've been trapped there for ages." The dark haired detective concluded just as the news said it.
"When did you ever look into Mount Ebott?" The other asked in confusion, looking over at him.
"... I haven't." His eyes narrowed.
"..." He quickly looked over to the other, and if it had been anyone not used to this kind of thing, they might have jumped from the sudden motion.
"Watari, Do you feel like you've been here before?" He asked curiously, pulling at his bottom lip with one thumb.
"... No, I can't say I do." the older man answered after a moment of thought.
"... Yes, I suppose it's just deja vu." He stood on the couch, hopping off as he walked away from the screen, slightly hunched.

"... Yes, I suppose it's just deja vu." He stood on the couch, hopping off as he walked away from the screen, slightly hunched.
How did I know he was going to say that? Why does this all seem so familiar? He pulled at his bottom lip in thought as his back faced the screen, the light of the stove clock in the next room flashing numbers in green.
"... The monsters seem entirely friendly, and one human child has been negotiating apparently quite well with the police and, soon, the mayor of Ebott City." He listened to the news cast.
It couldn't be... Had this happened before? Had there somehow been some sort of time loop?
He hadn't slept in a day or two. He wasn't thinking correctly. Immediately jumping to a conclusion that bold was nothing like him.
... That wasn't entirely true. His hunches usually shed at least some light on whatever he was looking into.
He would sleep on it. That was all he could do. Hopefully there would be some rationality in the morning.
Monsters, deja vu, everything almost repeating?
If he didn't know any better, he might think he was already asleep.
How long had it been? A month, maybe two?
The news cast. He could have muted it and mouthed the words.
"The human ambassador seems to have gone on some sort of rampage! They've killed all of the monsters' royal family and any of the monsters in their neighborhood. They are already moving on towards the human parts of the city, and people are beginning to go missing. Those in Ebott City have been advised to stay at home with their doors and windows locked, and roadblocks have been set up around the city. If you see The former ambassador anywhere, please, report it immediately. Do not try to confront them, though small they are incredibly dangerous."
He stared at the photo the news had put up on the screen.
Odd... They were just a child. Not tall, not seeming to be too muscular, not threatening at all. In fact it looked like they could have been an incredibly kind person.
"How could someone so innocent looking be so dangerous..?" Watari almost muttered to himself.
"Yes... It's a good question..." He pretended he hadn't responded to that who knows how many times.

"... Yes, I suppose it's just deja vu." He stood on the couch, hopping off as he walked away from the screen, slightly hunched.
Again. This was no dream, and this was no deja vu.
Something was very very wrong.
"... You look troubled, L." Watari noted out loud.
"... I will have to... Look into this." He said more to himself, walking off through the kitchen and into another room.
If memory served, he only had about six to seven months before the next reseting of the world, if that was what it was.
He would watch for a month or so. He would watch closely. And then...
Everyone would think him crazy. This theory of his was completely unbelievable. He'd sooner believe a book could kill people if their names were written in it.
... Oddly specific.
"You usually don't go out often. Especially not while working on cases."
"What makes you think I'm working on something? I'm just curious about Monster society, is all." L lied with ease as he opened the door.
After a month of research, he'd decided he'd have to get a closer look. A closer look on these monsters and, more specifically, their ambassador.
He usually didn't go out much, Watari had told the truth. But if things truly were being reset, then even if he got into trouble, he'd be brought back at one point or another.
He couldn't just go knocking on their door. Well, actually, from all the nice things he'd heard, he might actually have been able to.
But... He wouldn't. Even then, what would he say? For all he knew, this child had nothing to do with this.
But his last hunch had been right...
He no longer felt deja vu. This was, apparently, the first time he'd done this.
L's untied shoelaces hit the ground and bounced as he walked down the street, hunched with his hands in his pockets.
He passed what seemed to be a small bar named Grillby's, paying it no mind.
He wasn't entirely sure what he was doing. Just walking around in hopes that he would run into that child?
Yet that strange gut feeling told him it wasn't a bad idea...
L stopped, looking up at the sign hanging over the building he stood in front of.
"Spider Bake Sale."
Perhaps one good thing could come out of this walk.
The bell above the door rang as he pushed the door open, looking around.
"Welcome! Ahuhuhu~" Greeted what appeared to be a humanoid spider.
"My my, what a surprise. We don't get many humans around here, ahuhuhu~." She said as L looked around the room.
It seemed to be a little dark. Usually stores like this would be better illuminated and less... Painted black walls.
"I can't imagine why." There was no sarcasm in his voice, but he knew it was sarcastic in his head.
"So what'll you have?" She rested her chin on two hands, leaning forward onto the counter.
L made his order. Just one donut. Maybe he'd come back for more if they were worth the money.
If L didn't have so much money, he certainly would've considered this place expensive.
"Come again. Ahuhuhu~" She said as L turned around, now holding a donut as his wallet was a little lighter.
As he turned around, he heard the bell on the door ring.
He showed no surprise on the outside as he spotted the child standing there.
But they certainly looked surprised to see him.
Almost as if something had changed in what they thought they knew so well...
His hunch had been confirmed.
... Sort of.
"... Is there something wrong?" L asked with a mouth full of the donut he'd bought. "You've been staring at me for thirty seven seconds."
"O-oh..! Um, no, no, nothing at all! I'm just surprised to see another human in here! Usually I'm the only human who drops by here." They said, smiling.
It was hard to tell, but L knew it was forced.
L let out a small 'mm' as he swallowed the last of the donut.
"Hm, not anymore. I think I'll come by here more often now." He said, wiping his fingers off on the napkin the donut came with.
He walked right past the human child, and they looked over their shoulder at him, their eyes narrowed in what could have been considered a glare.
"Oh, and, Ambassador," L stopped in the door way, not looking over his shoulder at them.
"You really shouldn't give people that dirty of a look." They recoiled in surprise at that.
"They might get the wrong idea. I mean, you want everyone to know you're nice... Right?" L couldn't help but smirk as he looked over his shoulder at them, and they seemed to jump back into their act.
"O-oh! S-sorry, I was just thinking really hard about something!" They smiled innocently, rubbing the back of their head.
"Hm. Of course." L continued out the door, the bell ringing once more.
"... Who was that guy?" They muttered to them self as they looked back to Muffet at her counter, going to order.
Guilty. Obviously guilty. They clearly hadn't seen him coming. They thought they'd known everything that would happen, and seeing L was unexpected.
This child was no genius. Figuring them out would be easy.
L took note of music getting closer. Something like... Bababa-baba-baddadadadda...
He looked over his shoulder, eyes widening slightly as an orange car swerved towards him.
He jumped back, the car jumping the curb and nearly taking out a lamp post.
"Nyeh heh! My parking is improving!" A skeleton said loudly as he moved his head up from the steering wheel it'd landed in.
L just stood there, eyes somewhat wide in surprise.
"Oh no! It appears that I have almost hit a human!" Who was he talking to when he said that?
"Human, are you okay?" The skeleton jumped from his car.
"Worry not! I, The Great Papyrus, will help you through any trauma!"
"Erm..." L almost had to shake off the shock from everything that was suddenly happening.
"It's... Fine, I assure you." L said, raising his hands defensively.
Papyrus suddenly grabbed him by the wrist, still smiling confidently as L's eyes moved to his grabbed wrists. If this were some sort of cartoon, a dotted line would have formed between his eyes and hands.
Papyrus picked L up with ease, setting him down in the car before jumping over him and into the drivers seat.
Am I being kidnapped by a jolly skeleton? L wondered to himself.
"This calls for emergency spaghetti!" Papyrus said, the car suddenly flying back down the street in reverse, making L's eyes widen in shock as he gripped down on the door hard, quickly throwing a seat belt over himself.
L stumbled slightly as he left the car, eyes still widened.
"The comfort of the Great Papyrus' spaghetti will surely calm your nerves, human!" Papyrus said, quickly pushing L inside of the house they were stopped in front of.
L glanced up at the roof of the house before they entered, noting that it was covered in snow despite it being summer.
"SANS! I told you to clean off the roof!" Papyrus stomped, staring up at the railing to the upstairs.
"C'mon Paps, you know I don't like being up on those shin-gles." A much shorter skeleton said, suddenly standing next to Papyrus.
"Besides, I was bone tired after a long day a doin' nothin'." Sans shrugged, winking one eye shut as Papyrus groaned loudly in irritation.
"Who's the new guy?" Grin ever lasting, Sans looked past Papyrus to L, who still seemed to be shaking off that car ride.
"Oh! Right! Spaghetti!" Papyrus ran into the kitchen.
"..." Sans watched him leave with that grin, the white dots that were his pupils looking back to L after Papyrus had disappeared into the kitchen, the banging of pots and pans being heard.
"Haven't seen you around before." Sans winked his right eye shut.
Something about how he said that... Did he mean he hadn't seen him in any of the resets?
"Well, I haven't been here before." L silently hinted at the fact that this was the first Reset that he'd came here.
"Name's Sans. Sans the skeleton." Sans offered his hand for a handshake, his grin seeming to widen.
"..." L took note of something wrapped around his hand, and decided to keep his hand back. For safety purposes.
"... Just gonna leave me hangin'? That's fine. Not everybody likes handshakes." Sans glanced to the side, grinning.
"Ryuzaki." L introduced himself with a fake name, as per usual.
"So what brings you to the Monster side'a town?" Sans asked, winking one eye shut in question.
"Business." Not entirely a lie.
"Well I sure hope Paps' antics didn't interrupt anything." Sans said. "Say, why'd he kidnap you anyway?"
"He almost hit me while attempting to park. Apparently he felt bad about it, so he... Forcefully invited me over for spaghetti." L's eyes darted to the side, as if questioning his own story despite it being true.
"Heh. That's Papyrus for ya. My bro's so cool." Sans closed his eyes. "Just uh... Don't be too harsh on his spaghetti, 'kay? It's still a work in progress."
L nodded before the door opened, and the both of them looked to it.
"Sans? Papyrus? Mettaton's show is on, you wanna wat-" They stopped upon spotting L standing there, recognizing him quickly.
"Oh, heya Frisk." Sans waved once. "This is Papyrus' new friend,-"
"Ryuzaki." L said, stepping forward and offering his hand for a handshake.
"Oh, right. you're the guy from Muffet's bakery, right?" They smiled falsely, shaking L's hand. "I'm Frisk! Nice to officially meet you."
L said nothing as he pulled his hand back casually, pulling out a wipe from his pocket and wiping his hand down, making Frisk give him a confused look as Sans just kept that grin.
"It's nice to meet you too." L said as he put away the wipe, placing his hands back in his pockets.
If Frisk wasn't smiling, they'd be glaring. Funny... L still felt that someone was glaring at him, even though both people in the room were wearing smiles. Both of which felt at least somewhat faked.
And it almost felt like... Was there another person in the room?
Peculiar... L thought to himself, before Papyrus' head popped into the room.
"Spaghetti's done! Oh, hello Frisk!" Papyrus boomed, and Sans and Frisk glanced at one another somewhat nervously before walking into the kitchen, L following closely behind.
The door suddenly flung open once more, and L, the only one left in the room, glanced over in mild surprise. Does no one knock in Monster Society?
"Hey Papyrus! I saw you took out your mailbox again, it was aweso-" The fish woman stopped mid sentence upon spotting L, who stared at her with a blank expression and semi-wide eyes.
"INTRUDER!" She suddenly yelled, pulling back one hand as a blue energy spear appeared in it.
L ducked, the spear soaring over his head and crashing into the TV.
He was now crouched down, one hand on the ground, which glowed blue under him.
He looked down, eyes widening as he suddenly jumped high into the air, expression still generally unmoved as a spear shot from the ground below him, disappearing before he landed.
"Wait-" L held up both hands as a red heart appeared on the left side of his chest, catching his attention for a moment.
When he looked back up, he realized there was a scaly fist flying right at his face.
He barely moved his head to the side in time, pulling one leg back and throwing it forward, slamming it directly into his attackers abdomen and making her hunch over as he quickly jumped back away from her.
"Please stop." L asked calmly as she stood again, growling in irritation.
"Oh it is on!" She said, pulling another spear back as it appeared in her hand.
"Undyne, wait!" Papyrus said, grabbing Undyne by the elbow and stopping her throw.
"Huh?! What is it?!" Undyne said, looking over her shoulder at Papyrus.
"That's my new friend! Taller Human!" Papyrus grinned wide.
"Woah wait, you made a friend? That's awesome Papyrus!" Undyne grinned, before looking back to L, her eyes narrowing. "But he looks kinda shady..."
"I get that a lot." L said casually, looking to the side.
"Enough dilly dally! There's spaghetti to be eaten!" Papyrus put an arm around both of them, practically dragging them into the next room.
Sans and Frisk seemed to be washing their dishes already, and L was pretty sure they'd just scraped it down the sink.
L didn't like things that weren't sugary. In fact, he eaten anything without at least some sugar in it in at least a few years.
He stared at the bowl left for him as he and Undyne sat across from one another. The way he sat got him a few strange looks, but he was more concerned with the food in front of him.
He couldn't turn it down, he might hurt Papyrus' feelings. That wasn't actually of much concern to him, but what Undyne might do if he wasn't a friend anymore certainly was.
Held hostage to eat spaghetti made by a skeleton who likes to say Nyeh heh heh...
Seriously what is today? L wondered to himself, looking around the cupboards.
He stood, seeing one that was open and grabbing a sugar container.
Maybe this would make it... Passable?
He poured in what many would consider too much sugar for spaghetti, stirred it in and skeptically took a bite, everyone watching with great confusion. Well, other than Papyrus.
"Uh... Don't you know you're not supposed to put sugar on spaghetti?" Undyne asked, heavy confusion showing on her face.
"Mm, I disagree." L said with a mouth full of food. "I think anything can have sugar put on it." Not entirely accurate.
Frisk watched with serious confusion as L actually managed to eat the bowl of spaghetti, Papyrus watching with stars in his eyes.
*... He actually seems to be stomaching it.
*This Ryuzaki is certainly one to keep an eye on.
Their eyes narrowed at the text box.
"Yes! Sugar in spaghetti! Genius!" Papyrus said, taking notes.
"Oh boy..." Sans muttered.
"This'll set back the learning how to cook actual food process..." Undyne muttered to him, and he nodded.
"Thank you." L thanked blankly, Papyrus quickly taking his bowl and running it over to the sink.
*Try to figure out more.
Frisk nodded after reading the text box.
"Hey, how about we all go back to my house for butterscotch cinnamon pie?" Frisk suggested, knowing Undyne would want something to wash that taste out of her mouth.
"That's a great idea!" Papyrus said, Undyne silently thanking them.
"... I like pie." L thought aloud, shrugging.
"Mom, I'm home!" Frisk called into the house, opening the door and walking through before everyone else followed in.
"Oh, hello my child! And I see you've brought some of our friends ove-" What appeared to be a goat woman stopped, looking to L in surprise.
"U-um... Hello there! Are you a new friend of Frisk's?" She asked, holding her hands in front of her self politely.
"... Something like that." L said, hands in his pockets as he slouched slightly.
"Papyrus almost took him out with his car. Then he invited him over for regretti spaghetti." Sans grinned, glancing to the side.
"Oh! Are you okay?" Toriel asked, quickly stepped closer and checking him for injury.
"I'm fine." L assured, somewhat surprised by her care.
"Well, here, come quickly!" Toriel gestured for them all to follow, smiling as she lead to a kitchen, where a large pie sat on a table.
It appeared to already have a slice missing.
Toriel looked, or, glared, over at another large goat person, who wore the expression of a dog that'd just been caught tearing up the furniture, mouth full of pie.
"... Asgore..." She said through gritted teeth, Asgore gulping down a bite of pie.
"O-oh... Um... Was this... Not supposed to be eaten..?" Asgore's eyes shifted nervously.
When Toriel looked back to the pie, she realized a second slice was missing, and looked to L, who sat crouched in a chair, looming over the piece of pie that he'd gotten himself.
He looked over to Toriel, mouth full of food.
"... Sorry." He said, voice muffled by pie.
"..." Toriel sighed. "Alright, everyone eat."
This was certainly a happy little place. But, knowing the future of it...
L glanced across the table to the squinting child eating pie, smiling and laughing with everyone else.
Could they... Really be capable of all those horrible things?
He got that feeling again. Like another was looking at him, glaring holes in him.
Yes, they were capable. Something about that child was... Evil.
Strange... Seeing such an important family being... Well, a family.
Or, seeing any family being a family.
L didn't really know what those were like.
Sure, Watari was a great caretaker when he was a child, but as one could guess he'd always been some kind of outcast. Which was fine, he didn't regret that.
But... All these people, sitting here, laughing and being happy? That was certainly strange. At least to him.
"So, Ryuzaki, it's certainly strange seeing a human come around Monster Town. Not that you aren't welcome, of course. I'm just curious as to why you came here." Toriel asked curiously.
"Business mostly. I was also curious to see what monsters are like. They are certainly more inviting than most humans." L said, taking a bite of pie directly afterwards.
"Ryuzaki doesn't really sound like a name from around here. How far did you travel to get here?" Asgore asked curiously.
"You know, I get that a lot." L lied easily, pointing his fork casually at Asgore as he spoke. "I honestly have no idea why my parents gave me such a strange name." He shrugged.
Some more small talk.
Eventually L figured he'd stayed long enough.
"Do you want me to drive you back to your home taller human?" Papyrus asked, and L quickly shook his head.
"No no, I have someone coming to pick me up." L said as he opened the front door, stepping outside.
As if on cue, A black car pulled up, windows tinted.
"It's been fun." L said as he opened the door, everyone surprised by the looks of the car.
"Wait! Are you going to visit again?" Papyrus asked, and L looked directly at Frisk, who stared blankly from the back.
That glaring feeling... It seemed like someone was glaring at him from over their shoulder. So, he looked over their shoulder.
"Count on it." He gave a somewhat creepy grin. The creepy part wasn't on purpose, it was just something that came with his grins.
The window rolled up, and the car drove away.
Frisk looked down at the text box, noting the red letters.
*He was looking right at me...
*Heheheh...
*Game on.
He knows.
So yeah, this is my little idea on an Undertale Death Note cross over, because there are not enough of them.
I've basically got this chapter and the last chapters figured out so... Yeah. Everything between then'll be a challenge.
Typing this was mostly just to get my mind off my other stories, which felt like they were getting too serious.
If you've read my stories you know this is a shockingly short chapter for my usual standard, but I just felt that was a good place to end the chapter.
So we've got L already this close to the cause of the RESETs, and already has them and... Whatever mysterious force with them as his prime suspect.
It seems like he figured out too much for a first chapter, but think about how fast L works? He's the world's Greatest Detective, and Frisk probably isn't exactly on that intellectual level. Not to mention the fact that he caught them completely off guard.
He's still just going on a hunch though, but trust me... He'll find out more soon enough.
He's L, after all.
Well, I mean, this'll happen if you Favorite, Follow, and Review. Because uh... While I know having a third story to work with is probably an awful idea, I just can't help myself.
I need to like... Go to rehab or something.
So uh... If you've read this far, you've gotta enjoy something, right? Please review and tell me what it was. Like... Seriously.
