READER'S POV

After hearing the incident and of course, hearing the two staff talking about a VERY familiar individual, the four of us chased him down and made him confess about what happened to that poor woman.

"Let's hear it," Lucifer spoke with a frown.

"Whaddya mean let's hear it?!" Mammon shouted with a frown.

"What did you do this time, Mammon?" Satan asked with a frown.

"I told ya, nothin'!" Mammon told us but the others weren't buying it.

Man A: "He killed her! He killed that woman!"

Woman A: "That's right! He stabbed her with a knife!"

Man B: "Hey, you four. Are you with this man?!"

"Nope, sorry. He's a total stranger," I spoke with a frown.

"Wh...?! (Y/n)! I don't believe it...after everything I've done for you! How 'bout you show me some respect, huh? And some gratitude while you're at it!" Mammon complained.

"Honestly, you're like a magnet for trouble. Everywhere you go, it follows. You need to stop this..." Lucifer grumbled.

"He's right, try cleaning up your own mess for once," Raven spoke with a frown.

"Stop what?! Like, I'm just an innocent bystander here!" Mammon shouted.

"Well, in any event, you'd better tell us what happened...and start at the beginning."

"I heard there was a car on the train where you could go to eat, so I went lookin' for it! I was gonna take some pictures and then show them to Beel later. You know, to brag. But then...

FLASHBACK...

3RD PERSON POV

"Eh...? Wait...is this a dead end?" Mammon wondered as he looked around the cart.

"Nah, couldn't be...Oh hey, there's a sign here. Let's see... 'No admittance. This car has been reserved for a private party'. What, seriously?" Mammon asked outloud.

"Wait though, if I can't get through here, I can't get to the dining car, can I...? Pff, you can take your 'reserved car' and shove it. I'll just pretend I can't read human world writin' ...Yep, that works. In I go..." Mammon spoke as he opened the door. "'Scuse me, come through..."

As soon as Mammon opened the door, everything went pitch black.

"What the...? Man, it's dark in here...!"

Mammon then heard something move in the darkness and he asked outloud, "Wait, what was that? Someone in here?"

Four people were around a medium and they were chanting some spell. "Elohim Essaim Frugatuvu et appelavi..."

"Come to us...we beseech you..."

"Hear our words...heed our summons..."

"Show yourself...appear before us..."

"Yo. What're you guys doin'?" Mammon interrupted them.

They stopped chanting as soon as Mammon interrupted them.

"It's a spirit...!" One of the men shouted with a surprised look.

Suddenly, the woman screamed and that shocked Mammon. "Wha?"

The spirit medium that was chanting suddenly collapsed onto the floor.

"What happened?!"

"The spirit medium...she collpased! What's going on...?"

"Look...blood! She's been stabbed in the back..!"

"Mammon..." The spirit Medium whispered.

"Hey...hey, are you okay?! Talk to me!"

"It's no use. She's stopped breathing..."

"It sounded like the last thing she said was 'Mammon'. What could that-" The woman stopped herself before looking at Mammon.

"Mammon, huh...Well then, seems she decided to name someone great and noble in her last breath. I'm guessin' she'd always wanted to do that...and I don't blame her. Cause it just so happens to be MY name, ya see! Say hello to MAMMON...the one and only," Mammon grinned but, that was soon wiped off his stupid face.

"So then, she said your name in her dying breath...?!"

"It must have been a message...! She was trying to tell us who killed her!"

"YOU...YOU MURDERER...!"

"Huh?" Mammon looked at them with a confused look.

FLASHBACK ENDS...

READER'S POV

I sweat dropped when he told us the full story and no surprise, his stupidity kicked in once again.

"Just how much of an idiot are you?" Lucifer asked with a frown.

"A pretty big one, that's for sure," Satan spoke with a frown.

"HEY! These people are treating me like some sorta criminal, y'know! So how about you defend me here, huh?!" Mammon shouted.

"You never think before you act. That's why you're always getting yourself into these situations, you complete and utter moron," Lucifer spoke with a frown before hitting him.

"Hey! Th-That hurts..." Mammon complained.

"None of this would have happened if you hadn't insisted on telling them your name. But being the total fool you are, you just had to, didn't you?" Satan asked with a frown.

"Don't be too harsh on him. It was just bad luck, that's all," I told them.

"Exactly...yeah! It wasn't my fault. In fact, I'm the VICTIM here!" Mammon shouted.

"(Y/n), I don't know why you'd actually come to his defence, but stop. You're only encouraging him. And he's annoying enough as it is," Lucifer spoke with a frown.

"Hey! don't gotta be mean!" Mammon complained.

"Well, we're going to have to do something about this," I told the others.

"I don't believe this. As if we needed another problem to deal with..." Lucifer grumbled.

"Only one version of events is ever true!" Satan spoke with a smile as if he's in some sort of detective movie.

"Eh? What're you talkin about?" Mammon asked with a confused look.

"It's a line from 'The Mid-Fall Murders', a human world crime suspense series. That was the lead character Inspector Adler's famous catchphrase. 'The perpetrators had best give themselves up now while they still have the chance. Because I will find.' I never thought the day would come when I'd actually get to say that in real life..." Satan smiled.

Raven and I looked at each other with confused expressions before Lucifer spoke up, "I'm not sure I completely understand what this is about, but I can tell you're motivated, and that's what's important."

"You four, this is no time to be standing around joking! If this man is a killer, then we'll just hand him over to Scotland Yard at the next station-"

"I think all of you should go and wait in the dining car for now. Goodbye..." Lucifer grumbled while glaring at them.

Man A: "...Right,  good idea. We'll let you guys track down whoever did it. Okay everyone. Let's go and to the dining car."

Man B: "Right..."

Woman A: "Yes, Good idea."

Once the three people have left, we turned our attention back to the scene of the crime and I mean that literally.

"So...what just happened?" I asked them.

"It's one of our powers as demons. We're able to manipulate humans, sort of like a form of hypnosis. Ah, but Lord Diavolo has explicity forbidden anyone from doing that to you, do don't worry. As long as we're on the subject, I should note that Asmo's power to seduce others is an even more powerful form of manipulation," Satan explained to me.

"Please don't remind me. He even tried to use that charm of his on me but it backfired and I never understood why," I told Satan.

"That's because once in a while we come across special humans who are immune like that. Almost all of them turn out to be witches or sorcerers...people with exceptional magical power. But in your case-"

"Wait a minute! This woman...the murder victim-" Lucifer interrupted Satan.

"I told ya, it wasn't me! I didn't stab her, okay?! I don't even have a knife on me!" Mammon frowned.

"...This is Grisella," Lucifer told us.

"What did you say...?!" Satan asked with a shocked look.

"I'm certain of it. It's Grisella, the witch we were supposed to be going to see," Lucifer told us.

"You gotta be kiddin' me...!"

***

"All right, I will no prove to you that the man you see before you, Mammon, is innocent," Satan told the three people after we talked over how she was killed.

Man B: "Innocent?! But that woman called out his name right as she died!"

"Yes, because the truth is she actually knew him," Satan told them bluntly.

"What did you say...?" The woman asked with a shocked look.

"Just before she died, someone she knew appeared before her unexpectedly. It seems that's why she said his name in those last moments," Satan explained to them.

"If that's true, then she might not have been trying to name her killer," The woman spoke with a surprised look.

Man A:"B-But that man went inside the lounge, and moments later she was killed! The timing is a little too perfect to be a coincidence."

"Indeed. It's only natural that you would think Mammon is the killer," Satan spoke with a smirk.

"Listen to Satan, he's loving this," Lucifer mumbled.

"What did you expect from a guy who loves reading crime books?" I asked while Raven nodded his head.

"Dammit...here I am accused of murder, and HE'S havin' a good time..." Mammon grumbled.

"By the way, where at the table was the spirit medium Grisella? Where was she sitting?" Satan asked.

"Where? ...Well, she was in a chair facing away from the door out into the hall," The woman explained to us.

"Precisely. And Mammon came through that door into the lounge, the same one she had her back to. As soon as everyone inside realised that someone was intruding on them, they all turned to see who it was. Which means that Grisella had to have been facing Mammon's direction," Satan explained to them.

They were all shocked and surprised by this explanation before he asked them, "Starting to make sense now, is it?"

"Wha? Wait a minute, no...I'm TOTALLY lost here!" Mammon shouted.

"Grisella was stabbed in the back, correct?" Lucifer asked him.

"Yeah...So?"

"Do you think yourself capable of stabbing someone in the back if they were looking at you, Mammon?" Lucifer asked him.

"Huh? Lemme see..." Mammon mumbled.

"The long and short of it is that given your position, you couldn't have stabbed her. Now do you get it?" Satan asked with a frown.

Man A: "Hmm, you do have a point..."

"Huh? Like, really? ....Huh?" Mammon asked with a confused look.

"In any event, we should go ahead and seal off the lounge until we reach the next station. Whoever did this is still hiding somewhere on this train...Everyone, Id' ask you to remain inside your cabins until further notice. Only one version of events is ever true!"

 Raven frowned and smacked him upside his head.

"Ow! what was that for?"

"Hahaha! nice one Raven," I spoke with a smile.

"Raven! that's my body you're hitting!" Lucifer shouted with a frown.

"Don't worry, that was one time," Raven spoke with a proud smirk before we made our way back to our cabin.

Once we got back to our cabin, we sat down on the seats and then Lucifer sighed and then Mammon asked him.

"Hey, why the sad look? You know we've proven that I'm innocent now, right? I mean, I know it must've been a real shock 'cause your sweet brother was treated like a criminal and all. But still..."

"If Grisella is dead, that means that we can't lift the curse that caused us to switch bodies...So, in the end, we came all this way to the human world for nothing, and the speech is tomorrow..."

"Sucks to be you right now, Luci," Raven told him.

"Hey! Why aren't you worried about me, huh?! Let's see some concern, dammit!"

"Well, this is just wonderful. I don't believe it. What a miserable state to be stuck in..." A voice spoke up out of nowhere.

"Wh...!"
