Chapter 0: -[Redacted]-

At a certain location, a group of people, consist of 4 female figures were infiltrated the place in silence. Each one bringing their specific weapon, capable to help them in case of firefight broke out. They are moving in professional and careful, watching every corner of possible contact they needs to evade in their current job. Once they are arrive in front of door, they are waiting for a bit until the door's lock unlocked by some reason and entering the place they need to go to complete their mission.

They are Team 404, A.K.A the "Unknown" by many due their jobs nature in stealth mission that requires no trace of them being there. Consist of 4 "renegade" T-Dolls, leads by UMP45 and the members are UMP9, considered as UMP45's sister, HK416, a professional-looking T-Doll that scream "no non-sense" in her line of work, and last but not least G11, the shortest among them and seems always look tired or sleepy for some reason, but still doing good on her job.

UMP9: Is this the place?

UMP45: Yes. From the information we got, this is the place. I'll hack the computer. 416, 11, watch our back.

HK416: Affirmative.

G11: Okay.

While 45 doing her job, 416 and 11 are standing near the entrance, watching if there's any enemy around they need to deal so their presence won't be discovered. 9 was watching her sister work until she brought out a conversation.

UMP9: Say... we have infiltrated the place and so far is nothing wrong, but what about him? Can he does his job properly?

HK416: If he didn't, he would be long death rather than being here with us in this mission. Why are you worried for useless thing?

UMP9: Well... this place is full of those SF dolls and he basically has very little equipment on him right now. Supposed he got discovered, didn't mean he's pretty screwed up?

G11: Considering his luck, it is unlikely for him to get caught by the enemy. Remember the last time we thinks he was death but suddenly appear safe and sound while drinking cola back on our hideout?

UMP9: Yeah... that was one hell of stunt he did. No wonder a lot of people is so convinced that he was death after so much dangerous jobs he does yet he escape the death like it was nothing.

HK416: Can you two chat later? We are in mission right now.

UMP9: Yes ma'am, but aren't you also worried about him?

HK416: Worrying about him is pretty much waste of time. He always got the job done and I found nothing is wrong about it, except his tendency to show up in unexpected condition.

While they are talking, 45 was done with her job as the computer in front of them let out a error sign, means their job are pretty much done for now.

UMP45: Alright, with this those Griffon's dolls won't have problem to attack this place. Let's retreat before any enemy show up.

Everyone else: Affirmative/ okay... / alright, let's get the hell out of this place!

They then moving from the place before their enemy suspect something wrong with the place. So far, they're only meet with low-tier enemy they easily dispose without altering their enemy commands of their presence. After a quite amount of time, they're successfully escape the place and was heading back to their place, until 9 realize something.

UMP9: Hey, where is he? Did we already told him about the rendezvous location?

UMP45: Now you mention it, he never answer our call. Did he get into trouble?

G11: Should we help him?

HK416: I don't think we need to. So far, no alarm is off so I can say he is still pretty much undiscovered. I won't be surprise if he suddenly appear behind me right now.

Almost coincidently as she said, they heard a sound of something moving behind 416. Everyone become alerted and pointing their gun on the place. It the proved that they action aren't needed as a familiar figure was approaching them.

[ ]: Kept you waiting, huh?

UMP9: Zero! There you are! I thought something happen to you when you didn't answer our call!

[ ]: Well, sorry about that. I was so close to this high-tier doll unit that I can't even make any noise so sorry if I can't answer the call.

The figure that appear in front of them is Zero, the fifth "unofficial" member of Team 404, known by many codenames but mostly refers as [ ], the "Blank". He was a young man, probably in his mid-20 due his appearance that "old enough to be considered as adult, but young enough to be mistaken as teenager". His natural white hair with some black steaks is the most noticeable feature of him beside a scar that appear in his neck, near the throat that was covered by black tape. His name, Zero is not even his real name as due the nature of his job he never has clear background nor information about him. He himself admit he forget his real name due many identities and alter egos he has for sake of his job line.

HK416: I see. Then, how about your job? Are you able to accomplish your objective?

[ ]: Hey, relax! I got it covered. You should learn to be relax a bit 416 or you might turned old—

HK416: (pointing her gun at Zero's face) what did you say?

[ ]: Nothing! Nothing at all, so can you put your gun away?

416 put her gun away from him. For everyone in Team 404, this is already a daily occurrence where Zero would tease or unintentionally getting 416's nerve and she will answer with her gun straight on his face. So far she never actually pull the trigger, but he won't dare to take a chance, despite his carefree attitude.

UMP45: So, did you put the fireworks?

He didn't say anything as he simply snap his finger when 45 asking. Suddenly, the base they once infiltrated before was caught in several explosions, which turn the place disarray and chaos in matter of seconds. Everyone beside him was witnessing his "works" and gains difference reaction from them.

UMP9: I though you just put some place in fire or something...

G11: That one hell of explosion you cause...

HK416: I just hope it won't affect our result later...

UMP45: Hah... Zero, come here. (Zero approach her before she hit his head) Next time, use smaller explosive.

[ ]: Yes ma'am.

UMP45: Alright, our job is done here so let's head back to the base. Zero, you're responsible for cooking the dinner.

[ ]: Wait a second, it is 9's turn now, is it?

UMP9: Hold on, I thought it was 11's turn!

G11: You know that I can't cook, right? Should it be 416's?

HK416: My turn is next week. Last I remember, it is Zero's turn now.

[ ]: Dammit... I thought I can relax back home...

UMP45 approach him as she give him a pat on his back. Zero knows it was his lose so he accept it while walking with them in depressed mood. UMP9 tried to cheer him up, only to turn into unexpected argument between them, which was stopped by 416's "preparing to shoot" warning. Despite their shenanigans, they are still doing their job professionally, and once again, Team 404 was never be found to be there, except the obvious result of their job. Regardless, there's no mission they can't accomplished, but it's not their hardest time, yet.
