It turned out that Sandy is The Joker... This is serious because The Joker is, in fact, very well known within the Hunter Organization.
Sophie: "Hah... Fiona is still asleep."
Siegfried: "I see."
Rosika: "Hmm."
Meliodas: "Mhm."
Lina: "Oh dear."
Violet: "I'm sure it'll be fine."
(Meanwhile)
Fiona: "Hahhh...."
She got up.
Fiona: "Hahhh...."
She took some pills.
Fiona: "My head is pounding..."
(Pump!)
Fiona: "Ugh... ahh."
She dropped the pills.
Fiona: "Hahh... this is what happens when you stay awake too long thinking..."
She picked up the pill and swallowed it.
Fiona: "Hahh."
(Meanwhile)
Sophie: "(Cough)... hahh... Well then, I'll make breakfast."
She stood up.
Sophie: "Hmm?"
The door opened.
Fiona: "(Cough)... mmm."
Sophie: "Fiona... are you alright?"
Fiona: "Sophie... I want to stay in my room... I'm not feeling very well."
Sophie: "Oh... of course... of course... Get some rest. I'll make you some green tea."
Fiona: "Thank you very much."
She went back into her room.
Rosika: "Hmm."
Siegfried: "Does this happen often? That she's too exhausted?"
Sophie: "Hahhh... She just never learns to rest... But these headaches are good because they at least force her to finally take a break... I told Ms. Valentine that we need a vacation, and she said Marcus, Rosalie, and even Rio and Colletta are already on vacation..."
Siegfried: "Hmm..."
Sophie: "I think the reason is simple. The other high-ranking members... still don't really trust Fiona... probably because of what happened back then."
Siegfried: "Hmm?"
Sophie: "Hahh... For Cossette, Fiona left Dark Umbrella without permission and even killed her superior, Lady Natasha... After she found out that Lady Natasha had intentionally sent her team on a deadly mission... Only Fiona and Cossette survived..."
Siegfried: "Oh, so Cossette has always been a member?"
Sophie: "Under the name Cruella... but it turned out she had falsified her age... The records said she was eleven... but back then she was actually eight... And now she's ten years old."
Siegfried: "Hmm?... Then Fiona returned to Dark Umbrella."
Sophie: "Yes... Master Meliodas desperately wanted her in the Lily Moon... And because she trusts him so much, even if it doesn't look like it, she accepted... Meliodas saved Fiona's life... when she was suffering terribly from the Howgarts Experiments... Even so, many Dark Umbrella members, especially the higher ranks, still don't like Fiona. First, because she's a survivor of the Howgarts Experiments. Second, because she killed Lady Natasha and left without permission. And third... because unlike the other Crows... Fiona follows her instincts... not orders... unless they come from Meliodas or Ms. Valentine... She's similar to her old mentor, Tom Fog... He was the same way... He didn't care what others ordered him to do. He followed what his experience had taught him... But Fiona is even worse... because she doesn't like most of the higher ranks... Understandably, since many of them worked with Lady Natasha and the former leaders, including Viktor, who approved the Howgarts Experiments... and many people suffered because of it... Fiona hates the higher ranks for exactly that reason... and doesn't listen to them."
(A few minutes later)
(Knock) (Knock)
Sophie: "Hmm."
She opened the door.
Sophie: "Oh... Hello, Mr. Einsenheim."
Einsenheim: "I want to speak with you... I have a mission for you... Hmm... I don't see Fiona here. Only you and your people. Where is she?"
Sophie: "She's not feeling well."
Einsenheim: "Hmph..."
He walked toward her room.
Sophie: "Ugh..."
Einsenheim: "Is this her room?"
Sophie: "Wait... You can't just walk in."
He shoved Sophie aside. He reached for the door, but suddenly Rosika appeared and grabbed his hand.
Rosika: "...Excuse me, sir... but... have you ever heard of showing respect? You just pushed Sophie..."
Einsenheim: "Out of my way..."
Rosika: "No."
Einsenheim: "Hmmm..."
He violently slapped her hand away.
Rosika: "Urkk."
Sophie: "Ugh... What are you doing?!"
(Crash!)
The door opened, and Fiona stepped out.
Fiona: "What's all the noise?!... Huh?"
Rosika: "Ghh."
She saw Rosika's hand bleeding... then looked at Einsenheim.
Fiona: "Was that you?"
Einsenheim: "Yes."
Fiona: "I see."
Bob appeared.
Fiona: "...You can do whatever you want to me... but you do not hurt my friends."
Einsenheim: "Friends... Hahaha... You mean these incompetent people?... Lady Mystery, you're really boring."
Fiona: "What do you want now?"
Einsenheim: "Hmm... No coffee?"
Fiona: "No."
Sophie was about to make some, but Fiona held her hand.
Fiona: "No... no coffee."
Sophie: "Fiona... he's one of the higher ranks."
Fiona: "I don't care... Do you have a mission that's actually urgent?... Apparently not. You have time for coffee..."
Einsenheim: "Where is your master?"
Sophie: "Ohhh."
Fiona: "Hmm... (Cough)... Okay... I've had enough."
She summoned Chika.
Sophie: "No... no, Fiona! Not her!"
A doll floated into the air.
Chika: "Hahahahahaha... hahahahahahahaha... hahahaha..."
Fiona: "I recommend you apologize. Not to me... but to Rosika. I can't control Chika... She kills anyone she considers a threat. Since you were foolish enough to hurt me... she'll probably kill you."
Chika: "Hehehe."
Chika floated closer.
Fiona: "That's because you injured Rosika's hand... So... do you still want your coffee, or are you finally going to tell me what you want? If you want to complain to Ms. Valentine, there are cameras here. They probably recorded you injuring my colleagues... Article 19, Code 61... Neither an officer, nor a Crow, nor a regular agent is allowed to injure a fellow colleague. If they do, the injured person has the right to defend themselves. If the attacker gets hurt in the process, it's their own fault... So... Mr. Einsenheim?"
Einsenheim: "(Cough)... There is a mission... for you."
Fiona: "Cool... and?"
Einsenheim: "...It's urgent... Documents... and... a... a powerful weapon has been stolen from us... here in Villicia."
Sophie: "What... How could that happen?"
Einsenheim: "That's exactly why I'm so furious..."
Fiona: "Yeah... and you take your anger out on a blind woman... Wonderful... That's not our problem... I only take missions from Ms. Valentine or my master. Not from you... The only thing I want to see from you is your back as you leave... Siegfried... escort him out."
Einsenheim: "It's urgent!"
Fiona: "You had time to yell at Sophie... injure Rosika's hand... and ask for coffee... Let me see... that was... ten minutes and forty seconds... Doesn't seem that urgent."
Einsenheim: "The weapon... the device... is Project Number 913!!"
Sophie and Fiona looked at each other in shock. Fiona grabbed him by the suit.
Fiona: "How could you allow something like that?! Are you insane?! Do you want innocent people to die?! You idiot!!"
Einsenheim: "Please... help me find it..."
Fiona: "Do you even realize what kind of weapon that is?! That's a weapon... capable of destroying almost an entire kingdom!... How could you lose something like that?!"
Sophie: "Fiona."
Fiona: "Ghhh."
She let go of him.
Fiona: "You create this mess... and we always have to clean it up... as usual... Hahhh... damn it... (Cough) (Cough) (Cough)... (Cough)."
Sophie: "Fiona..."
Fiona: "Hahh..."
Siegfried: "What exactly is this weapon?"
Fiona: "Haahhh... It's a nuclear weapon."
Siegfried: "Ugh!"
Rosika: "What?!"
Fiona: "Indeed. A nuclear weapon... It was built in the year 1120... It was created to serve as an extremely powerful weapon... in case a kingdom ever went too far... or if something like Nemesis happened... like in Balencia. But this weapon is so powerful... that it could nearly destroy an entire kingdom... And that is exactly what you lost..."
Einsenheim: "...Lady Mystery... I want you to help me... and... tell no one about this."
Siegfried: "But if it's that dangerous... then... then the others must have noticed."
Sophie: "No... Believe it or not, the device is only about the size of a cigarette pack..."
Siegfried: "Huh?"
Sophie: "Anyone could hide it in their pocket."
Einsenheim: "If you help me... I'll help you in return."
Fiona: "How?... All I see is that you made my colleague's hand bleed."
She gently held Rosika's hand and put a bandage on it.
Rosika: "I'm fine... Fiona, really."
Fiona: "Shhh..."
Einsenheim: "I'm sorry... She... was in my way... and... I lost my temper."
Fiona: "That's what murderers say too... I make no exceptions... Anyway... I want payment."
Einsenheim: "Ugh... How much?"
Fiona: "Twenty-five thousand Coil."
That's what the currency here is called: Coil.
Einsenheim: "What?!... Are you kidding me?"
Fiona: "No... Twenty-five thousand Coil... This is an extremely difficult mission... It's like finding a needle in a haystack."
Einsenheim: "Eighteen thousand Coil."
Fiona: "Twenty."
Einsenheim: "Twenty-one."
Fiona: "Twenty-two."
Einsenheim: "Eighteen thousand Coil... and... a brand-new television... A really good one... You can watch whatever you want on it."
Sophie looked at Fiona.
Sophie: "Pssst... Ask him what brand."
Fiona: "What brand?"
Einsenheim: "BGS... Big Grown Screen."
Fiona: "Hmm?"
Sophie: "Oh, deal! Deal!"
Fiona: "Deal."
Siegfried: "(Sweats)... Uh..."
Rosika: "Uhhmmm."
Einsenheim: "...Okay... Deal."
Fiona: "Make him a coffee... We don't want to be rude."
Sophie: "Of course."
She made him a coffee.
Einsenheim: "...Thank you... Uh... Rosika, right?... Forgive me, child... I... shouldn't have done that."
Fiona: "Mr. Einsenheim... Even if I don't entirely understand you... compared to the other higher ranks of Dark Umbrella... you're a good man... comparatively... of course..."
Einsenheim: "(Sweats)... Hehehe... I have to say, I like your honesty... That's good... (Cough)... Now, about the project... The kidnapper forgot something."
Fiona: "Hmm?"
Einsenheim: "Well... We're not stupid enough to build such a small machine that can... well... destroy an entire kingdom... without a condition..."
Fiona: "Okay?"
Einsenheim: "Well... hehe... The truth is... that little thing... I mentioned... is only... the switch."
Sophie: "Huh?... I thought it was small."
Einsenheim: "No... because... Dark Umbrella kept it secret... that the weapon... is actually... a living being."
Fiona: "Hmm?"
Sophie: "Ugh... A living being."
Fiona: "Is it a cursed human? That's the only way it could have lived this long."
Einsenheim: "It's... a... child."
Fiona: "Huh?"
Sophie: "Huh?"
Siegfried: "A child."
Rosika: "How... but it's over a hundred years old."
Einsenheim: "Yes... You see... it's a child with both an Arcane power and a curse... The curse prevents her from aging... and... her ability is... that this child can kill anyone... because of... her radioactivity..."
Sophie: "A living... radioactive human."
Fiona: "No wonder it's considered so dangerous... Wait... and this being is now... gone?"
Einsenheim: "Well, there is some good news... Around the child's neck are numerous devices that suppress her power... But I'm afraid they won't hold much longer."
Fiona: "How did this child end up with us?"
Einsenheim: "Hahhh... I don't know the full story... She was already there when I took over responsibility for guarding dangerous projects, creatures, and objects... I only know that, during Blackhein's era... Dark Umbrella found a child with such an ability... Dark Umbrella experimented on her until she became this powerful... It sounds cruel... because it is cruel."
Fiona: "Hahh... This Blackhein sounds like a sadist."
Einsenheim: "He is... One of the worst leaders... Anyway... We have to find that thing."
Sophie: "Don't call her a thing... That poor child."
Rosika: "Yeah... None of this is her fault. You made her this way."
Fiona: "Hmmm."
Einsenheim: "Okay... okay... the child... find the child..."
Fiona: "Why is she still a child?... She's over a hundred years old."
Einsenheim: "The curse prevents her from aging or growing."
Fiona: "Oh... Does that mean she still thinks like a child?"
Einsenheim: "Yes... that too... Oh... Right, take this."
He handed them a toy.
Einsenheim: "Her favorite toy... She calls it Mama... The child lost her parents during the war."
Sophie: "...Oh..."
Fiona: "Hmm."
She took the toy.
Einsenheim: "Oh... If she starts crying... run away immediately."
Sophie: "Okay."
He stood up.
Einsenheim: "Hmm... I'm sorry... and... thank you."
Rosika: "Hmm."
Einsenheim: "I'm sorry about earlier, Rosika."
Rosika: "...Hahh... It's okay."
He left the building.
Sophie: "We're... in serious trouble, aren't we?"
Fiona: "Yeah... But we need to get moving now... Who's coming with me?"
Rosika: "I am!"
Siegfried: "Me too!"
Sophie: "I'm coming as well."
Fiona: "Okay... I'm coming too."
Sophie: "But you're not feeling well."
Fiona: "Hahh... Yeah, I'm a little exhausted... but... I can't exactly rest... while... a radioactive child is wandering around out there... Let's help that poor child."
Sophie: "Oh... so you do feel sorry for her."
Fiona: "(Cough)... I mean... let's find the... child... (Cough)... I misspoke."
Sophie: "Hahh... Okay... But Lina, Violet, and Master Meliodas aren't here."
Fiona: "Yeah... Hmm..."
The door opened.
Lina: "Oh."
Violet: "Oh... Um... What's going on here?"
Sophie: "You arrived just in time... Stay here. We have a mission... There's a radioactive child outside."
Lina: "Hmm?"
Violet: "Um... Bro, what?"
Fiona: "We're leaving now... Stay here."
They had already left.
Violet: "Huh?"
Lina: "A radioactive child?"
Violet: "Hahh... But we bought ice cream for you... Oh well... Then we'll wait for them."
Lina: "Yeah... Okay. Let's wait for them."
Violet: "Then I'll go... hit the sack."
Lina: "Then I'll put the ice cream in the refrigerator."
