A few minutes later, in the hallway…

After Sae left the interrogation room and walked down the hallway, she stopped walking when she see both Goro Akechi (a fair-skinned, shoulder-length brown-haired, red-eyed guy wearing a white dress shirt with a long-sleeve tan peacoat with black buttons on it over the shirt, striped black and white necktie around his neck, black gloves on his hands, long black trousers and black shoes on his feet) and Junko Sakurai (a fair-skinned, long blonde-haired (which is tied up with a teal-coloured hair band into a ponytail style), light purple-eyed girl wearing the full Shujin Academy female school uniform with thigh high black socks and brown shoes on her feet) approaching and stopping in front of her.

"Akechi-kun and Sakurai-san!? W-Why are you two here!?" said Sae with a shock look on her face at both Goro and Junko.

"Hello and it's been a while since we last saw you and why so surprised to see us, Niijima-san?" said Junko in amusement at Sae.

"Do you have a long day, Sae-san? Is that why you look surprised to see the both of us?" said Goro concernly to Sae.

"Well… Hold on, I needed my director to step in to get access and I was directly responsible for this case. How did you two get approval?" asked Sae in disbelief at both Goro and Junko.

"Let's say we're just that fortunate to have Lady Luck on our side. Is that a problem for you, Niijima-san?" replied Junko jokingly and innocently to Sae.

"Enough with the jokes, Sakurai." said Goro in disapproval at Junko without looking away from Sae. "Don't mind her and to answer your question, we're here for the same reason you did. I am heading up the investigation team, after all. It's only natural I'd have the right to interrogate the culprit as well with Sakurai here wanting to get photos and story for the newspaper company that she worked for, don't you think so, Sae-san?" added Goro, answering Sae's question.

"They assigned you command!?" gasped Sae in more disbelief and shock at what Goro just told her.

"Yes, they did. Didn't they tell you about it, Niijima-san?" said Junko in confusion to Sae.

"No, they didn't and only now I knew about it from you two, Akechi-kun, Sakurai-san." said Sae.

"… Oh dear, can't believe that you're that gullible to fall for my joke, Niijima-san." chuckled Junko.

"What!?" said Sae as she scowled darkly at Junko for making jokes at her.

"Sakurai, that's enough now, I mean it. Pay her and her jokes no mind, Sae-san. We're actually and merely here to assists with the public security interrogation. Although, it's surprising for us to see how far underground it is… There aren't any others incarcerated here, yes?" said Goro.

"Which means nobody would ever know if things got a little violent down here… That sounds scary for the ones incarcerated here." said Junko.

"If I remember correctly… didn't you say there was another culprit besides the Phantom Thieves, Akechi-kun?" said Sae suspiciously to Goro.

"Yes, I did say that to you…" said Goro as he slowly nodded at Sae only for Junko to cut him off by suddenly laughing out loud.

"Oh, that? That was just an excuse, a lie that this charming detective prince here spread to fool and set them up. Isn't that right, Akechi?" said Junko quite happily to Goro while she also elbowed his arm with her arm a little.

"O-Oh, right! But well, what I say and did isn't as bad and cruel as Sakurai-san say it is. Forgive me for forgetting to tell and deceiving you about it, Sae-san. I do feel bad but if you wish to trick your enemies, you must first trick your allies." said Goro calmly to Sae.

"Yep, exactly as he said, Niijima-san." said Junko in agreement with Goro.

"I see… Guess that confirms it. So it was you, Junko Sakurai. You're the one who sold out the Phantom Thieves." said Sae as she glance at Junko.

"What!? Sakurai did and she keep it from me?" thought Goro as he glance in disbelief and surprise at Junko.

Flashback…

"I need you to be clear with me, Keiko-chan! Who am I supposed to show this to? …!? My god… You're referring to her, aren't you?"

Flashback ends…

XXXX

"How could you sold all of us out to them and didn't tell me about it, Sakurai? Unless…" thought Goro as he scowled at Junko.

"Oh whoops, sorry for not telling you about it, Akechi. And is there a problem, Niijima-san?" said Junko apologetically to Goro then curiously to Sae.

"Not really. Sakurai-san… Does this smartphone look familiar to you?" asked Sae as she take out and show both Goro and Junko the smartphone that belongs to Keiko.

"Hm? Excuse me?" replied Junko as she glance in confusion at Keiko's smartphone in Sae's hand.

"Isn't that Keiko's smartphone?" thought Goro as he glance at Keiko's smartphone as well before he felt the entire atmosphere around him, Junko and Sae distort and turned purple in colour for a moment.

"…? What is this phone, Niijima-san?" asked Junko as she glance at Sae.

"It's a smartphone, duh, Sakurai-san." said Goro as he rolled his eyes at Junko.

"It belonged to the leader of the Phantom Thieves. I believe the two of you'll need it for your investigation, photos and story for the newspaper." replied Sae calmly to them.

"Not really for me." thought Goro to himself.

"True but I don't think that Akechi and I need the phone for it. We were acting alongside the Phantom Thieves ourselves, remember?" said Junko.

"True. This is undoubtedly a great accomplishment even though it's a set up by you, Sakurai-san. Good luck in there, you two." said Sae as she nodded to both Goro and Junko then walked away from them.

"Of course, Sae-san." thought Goro in agreement with what Sae just said to them.

"What a foolish woman… Now that she's gone, time for you to be out of the way so you don't interrupt me as well, Goro Akechi." thought Junko with a wicked look and smile on her face before she suddenly knock Goro out, which make him grunt out in surprise and pain from Junko striking him and he fell unconscious on the floor before Junko walked toward, unlock and open a door of an empty room, drag and put an unconscious Goro into an empty room before Junko close the door, turned and make her way down the hallway toward the elevator, went in and went down and walked out of the elevator and down another hallway toward the interrogation room where Keiko is and with a dark blue-uniformed security guard standing outside the room.

"May I ask that you accompany me? I've to do it for my story about the captured leader of the phantom thieves and going in unarmed to interrogate a murderer makes me uncomfortable…" said Junko concernly to the security guard.

"Sure." said the security guard as he nodded at Junko, turned and unlock and open the door and both the security guard and Junko entered the room, saw Keiko sitting and staring at them in the room and after both the security guard and Junko entered the room, Junko suddenly grab and took the gun from the security guard before taking out and swiftly putting a silencer on the gun.

"Ah! What're you-" gasped the security guard as he turned to glance in shock and fear at Junko before she shoot him right at his heart with the silencer gun and he fell dead on the floor.

"Junko!? What have you done!?" gasped Keiko in shock and fear at seeing Junko shoot and killed the security guard in front of her.

"I owe you for all of this… thanks." said Junko emotionlessly to Keiko.

"No… It's you all along!?" said Keiko in more shock and fear at Junko.

"That's right, Keiko Amamiya, AKA Joker and leader of the Phantom Thieves. You and your little friends were vital to our plan. And now, it'll be completed and soon you'll lose Mallory Ananu Caelum to the rest of the "Old Ones" who had their eyes on her ever since she came to Tokyo, poor girl…" said Junko mockingly to Keiko about Mallory.

"No, not Maly!" thought Keiko sadly and worriedly in her mind for Mallory before she glared at Junko. "You and those "Old Ones" leave her alone! She never wanted or asked to be the host of an "Old One" called Lythalia!" snapped Keiko angrily at Junko.

"Your popularity truly was quite stunning. That just make using you all the more worthwhile… Have you finally pieced it all together?" said Junko as she ignored Keiko's angry words at her, approach Keiko before raising and pointing the silencer gun at Keiko's forehead.

"Case closed"… This is how your "Justice" ends, Keiko Amamiya." said Junko as she smirk wickedly at Keiko, pull the trigger and shoot Keiko, watched Keiko jolted a little from the bullet penetrating into her head and blood flowing out of the wound on her forehead before Keiko's eyes turned dull and lifeless and she fell dead on the table.

Meanwhile, in Leblanc…

Sojiro Sakura (a middle-aged, brown-eyed man with slicked-back receding black hair, a chinstrap black beard with a goatee that flares out, glasses on his eyes and wearing a light pink dress shirt with the sleeves roll up to his elbows, long white khaki pants and white shoes on his feet and a black apron with white stripes on it) is currently wiping and drying some cups with a white cloth after he washed them only for one of the cups to slip from his grasp, fell and break into pieces on the floor.

"…?" said Sojiro with confuse and worry look on his face at the broken cup on the floor.

Meanwhile, in a café in Kichijoji…

Mallory Caelum (a fair-skinned, waist-length crimson-haired (which is tied up into a ponytail with a teal and black stripe ribbon behind her head), silver-eyed girl wearing the Shujin Academy female school uniform with knee-length black socks and brown shoes on her feet) is currently eating and enjoying a piece of chocolate mousse cake before she stop eating, let out a small gasp of pain and clutching her chest with her left hand when she felt her heart suddenly throb in pain.

"Ngh…" thought Mallory with confuse and pained look on her face.

"What is it? What's wrong?" asked Akira Kurusu (a slightly fair-skinned, short wavy black-haired, dark grey-eyed guy wearing the Shujin Academy male school uniform with long black pants with red square stripe lines on it and brown shoes on his feet) concernly to Mallory.

"… Nothing and I'm fine, Akira, really." replied Mallory reassuringly to Akira (who kept on staring in concern at her) while thinking and feeling worry for Keiko.

Back in the interrogation room…

Junko lowered and used the silencer gun to poke and prod Keiko's head to see and make sure whether she's truly dead or not and once Junko's sure that Keiko's dead, Junko removed the silencer on the gun, put the silencer back into her blazer pocket, put the gun in Keiko's hands to make it look like Keiko committed suicide by shooting herself, glance and smirk at the dead body of the security guard lying on the floor before Junko open the door and left the room.
