AN I didn't mention this, but I'm going to be putting the timeline on the assumption that Maou was imprisoned at roughly 4pm.

Maou POV (Ten minutes after imprisonment)

"Hey L?" I ask, hands crossed.

I thought I heard him sigh, but it might've been my imagination, "Yes Sadao?" he answered.

"I'm bored," I inform him for the 27th time.

"I'm aware of that."

"Can you get me something to do?" I ask.

"No," He replied.

"Okay," I affirm, looking down at my hands, twiddling my thumbs. Left thumb over right, right over left, left over right. I look at the ceiling, deciding to triple count my count of how many dents there were. One, two… nope, there were still only 596 of them.

I look at the camera, "L?" I ask.

"What is it?" He replied.

"I'm bored."

"I have no intention of doing anything to assist in alleviating your boredom," L informed me.

"Okay, I'll just keep asking until I get something," I reply with a smile.

-Timeskip 3 hours later-

Tap, tap, tap, fly birdy fly! I screamed in my mind, watching as the small yellow bird bounced across the screen. L had let me use some sort of screen-locked phone that could only play flappy bird on my 274th time asking, so that's what I had been doing for the past hour and a half. This human game was incredibly easy, but surprisingly entertaining. I suppose it was harder for humans though, considering L's comment when I got to 100 on my third try (It took me two rounds to get used to how the game worked).

"Sadao, I am sending Watari to give you dinner," L informed me, I gave a thumbs up, continuing to tap with my other hand.

Sure enough, less than a minute after L spoke, a tray was pushed into my cell. I inched towards it, careful not to take my eyes off of my screen for too long, I found that I could finally understand Lucifer better. I quickly shoveled food in my mouth, trying to eat and play at once made this game much more challenging.

After I finished eating (I was so focused on my game I realize I didn't even figure out what exactly I was eating), I pushed the plate back to the little door it came through, and went back to focusing solely on my game.

"Sadao, I would recommend you try to go to bed soon," L told me.

I waved him off and continued to play.

-Timeskip Day Three of Imprisonment-

Tap. Tap. Black. Wait, what? I look at the screen, it was black! What happened? Did I accidently hit the power button?

"It appears the phone I gave you has run out of battery," L stated, "Please set it by the door your food comes through and I will recharge it."

"Okay!" I replied happily, setting it there.

It was gone seconds later, and I sat there smiling.

My foot started to tap.

I looked at the ceiling.

Right over left.

"Hey L?" I ask.

"Yes Sadao?" He replied.

"I'm bored."

.

.

.

"I thought you might be," he replied after a moment.

"Can you get me something else to do?" I ask.

"No, you haven't slept in the past 72 hours, it takes the phone you were using roughly 10 hours to charge, so if you were to go to sleep I'd think you'd be able to sleep through most of that time easily enough," he suggested.

Sleep, right, that was something normal humans did wasn't it? Why didn't I feel tired? Was it because… yup, apparently my magic reserves had gotten large enough to allow me to use magic to rest me instead of sleep, something I used to do subconsciously and constantly back on Ente Isla.

I lay down on my back, staring at the ceiling. It would probably be best if I pretended to sleep.

-Time skip Day 11 (AN Btw, I don't actually know if there's a limit for how far you can get in FB, but in this it goes on for pretty much forever)

Tap, tap, I tap the screen vigorously.

"You are aware that other then 10 hour breaks every 3 days, you have been playing that game constantly for the last 11 days?" L asked over the intercom.

"Yup!" I tell him, smiling.

Pause. "You are also aware that in the past 11 days, not a single criminal has been killed by Kira?" He asked.

"Yeah, but that doesn't mean anything!" I exclaim.

L POV

The chance that Sadao actually was Satan was now at 85%. Despite his excellent acting skills, I had notice that he hasn't slept a second since he was imprisoned, something even I would have trouble achieving. Additionally, he was unnaturally good at Flappy Bird, his high score being in the tens of thousands.

Suddenly the door flew open, and none other than Miss Yusa stood in the doorway, panting heavily. She immediately recognized me.

"Oh *pant* hello there *pant* you haven't happened *pant* to see Maou *pant* any time in the last-" She paused to take a few big breaths, leaning against the door frame, "-11 days?" She asked.

"Why do you ask?" I ask her.

"I think he might be up to something," She explained, managing to catch her breath. "So have you?" she repeated.

"And how exactly did you get here?" I asked, avoiding her question.

"I just looked everywhere," She told me, "And can you please answer my question?"

"Uhm, not to but in to this conversation you two are having, but who are you?" Matsuda asks.

"Oh! Sorry, where are my manners? I'm Emi Yusa," Miss Yusa introduced.

"Nice to meet you! I'm Taro Matsui," Matsuda told her, shaking hands.

"To answer your question Miss Yusa, I have been detaining Sadao under suspicion of being Kira for the past 11 days," I informed her. Matsuda seemed more than a little surprised I was so honest with her.

"Really? Has anyone died? I don't think anyone has if the news is anything to go by. Ha! I was right that evil, monstrous, horrible, ruthless, murdering, self-centered devil is Kira!" She shot out.

"I have detained two other people under similar suspicions," I added.

This seems to horrify her, "What? I mean, there're only two Kiras so why would you detain three people?" She asked, confused.

"It's because both Light and Sadao have the same percent chance of being Kira," Matsuda supplied.

"What!" She exclaimed, "Trust me, it's wayyyyyy more likely Maou is Kira than anyone else," She growled.

"Would you care to inform us of your reasons," I ask.

This seems to fluster her, "Huh, ah, you see, he totally wants to take over the world!" She exclaimed.

"I will ask him to confirm this claim," I tell her, turning on the microphone that's wired to Sadao's cell, "Sadao? Miss Yusa is here and we're having a rather interesting conversation so I thought it'd be best to include you."

"Eh-Emelia's here?" Sadao asked, and I heard a faint thud.

"Correct."

"Why?"

"Apparently she's been looking for you," I told him, "Miss Yusa, you seem to know Sadao rather well, do you know anything that might stop him from sleeping?"
"Huh?" Sadao asked over the com, clearly surprised I'd realised he was only faking sleep, "Emelia! Don't you dare answer that! If you do I swear I'll burn your precious church to the ground!" He exclaimed.

"Pfft! You'd have to get there to do that," She snapped.

"Uh, what're you two talking about?" Matsuda interrupted nervously, "Is Maou an arsonist? What church?"

Miss Yusa look at him for a moment, then a very satisfied look appeared on her face, "Ha! See Maou? You're much worse than I am," she pointed out, it was likely (90%) she was referring to when Sadao told her she was bad at keeping their secret.

"There isn't much point to censoring what you say, I recorded your entire conversation from a few days ago," I informed them plainly.

Miss Yusa seemed effectively shocked at this, "Wh-wha, that conversation? What conversation?" She stuttered.

"The hall where Sadao took you and Urushihara had security surveillance," I tell them.

"Um, not to interrupt or anything but what are you guys talking about?" Matsuda asked.

I started to answer him, "In a recorded conversation, Sadao was repeatedly called Lor-"

Miss Yusa's response to stop me from finishing was to tackle me, "N-nothing! Seriously, it's not important!" She exclaimed.

To get her off of me, I kicked her in the stomach, knocking her backwards a few feet. After perching on my chair again, I speak, "You are aware that this only increases the chance that Sadao actually is him?" I ask.

"Actually who?" Matsuda asked.

"Will Miss Yusa let me finish speaking this time?" I ask Miss Yusa.

She slumps over in defeat, "It'll probably help in my argument that he's Kira anyways."

"Wait! I didn't agree to this!" Sadao shouts through the mic, in response, I mute him.

"Sadao Maou, along with two others have suggested that they are from another world," I told Matsuda first.

"What? That's crazy! There's no way they're actually-" Matsuda started to say, but Miss Yusa interrupted.

"Watch," she commanded, and Matsuda and I watched as she extended an arm. A bright light surrounded her, and wind seemed to appear from nowhere, blowing her hair upwards. In a matter of seconds, her hair changed from red to silver, as well as a sword appearing in her hand and armor covering parts of her body.

"Woah," Matsuda commented.

Luckily I had braced myself and had no outwards reaction, "I'd say it's roughly a 90% chance Sadao Maou is who you say he is now," I spoke.

"There's more?" Matsuda asked, looking to me for an explanation.

"Perhaps it would be best to have Miss Yusa explain," I told him, turning towards her expectantly.

"Explain?" she asked, her sword disappearing again, "Well I suppose I should explain how my and Maou's world functions first. I'll try to summarize as best I can. Ente Isla is made up of five islands, one for each cardinal direction, and a center island. There's a variety of creatures, most shared with Earth, however, there is also magic, demons, and angels. Sadao is a demon, and I'm half angel, half human," She explained.

"Whaaa?" Matsuda asks, confused, "He doesn't look like a demon, or I guess, not how I'd imagine one looking."

"This world's magic works differently, making anyone who comes here, demon or otherwise, revert to a human form unless enough magic is gained. Anyways, the center island was the realm of the demons, and the other four were for humans. Sadao is, well there's really no good way to say this except outright, Sadao is the lord of demons, Lord Satan," She continued.

"S-satan?" Matsuda asked incredulously, "As in the devil?"
"Mhm," She confirms.

He looks between me and Miss Yusa, "And you expect me to believe that?" He asks.

"At this point in time, there is roughly a 90% chance that Sadao Maou is, or more accurately was, the King of Demons," I stated, "Sadao, I'm going to unmute you as well as turn on your video so we can see you. Watari?"

Instead of responding, Watari simply made Sadao's video turn on.

"Thank you very much!" He exclaimed angrily.

"Sadao are you really…" Matsuda trailed off.

"King Satan? Lord of all demons and awesomest demon alive?" Sadao filled in for him, "Heck yeah!"

"Sadao, I'm curious, what does your demon appearance look like?" I ask him, partly out of actual curiosity but more because I want to be able to assess what kind of threat he is.

Miss Yusa decided to add a comment, "And don't say you don't have enough magic devil! I know that if you're not sleeping you're obviously using your magic for energy!"

"Fine, fine!" Sadao replied, "But I won't waste too much energy holding it for an extended amount of time!"

-Two days later- unknown location-

"The human whose name is written in this notebook shall die," A man quoted, reading the pages of a non-descript black notebook, "Pity. Might as well have fun with this though."

AN And that's a wrap! Thanks for all the reviews 'n' everything. Aw, poor Satan, now even Matsuda knows who he really is… Also, thanks for the support for my idea of a sequel!

Cya later!
