It was a morning like any other in Kivotos. Wakamo walked close to the door of the Schale office carrying her trusted rifle in one hand and a shotgun in another.

"Hmmm, those Millennium girls said this was a shotgun that could open any door but how does it work?"

Wakamo stared at the shotgun and decided to do the most natural thing she could think. Without any hesitation she shot the hinges and the handle for good measure, then kick down the door.

"Sensei~ Your dear Wakamo has arrived~."

But instead of Sensei, the one who answered was gunfire. Three figures stepped into the corridor right after. A sphere was floating beside her, pointing its lens to the intruder.

"Kosaka Wakamo, suspended 3rd year student of Hyakkiyakko and one of the Seven Prisoners, nicknamed the Fox of Calamity."

The secretary of Seminar, Millennium's student council, Ushio Noa, introduced her opponent while not letting her sight out of her notebook.

"Nin nin! If it's to protect my Lord I don't care who my ninja arts face, I shall not hesitate!"

The self-appointed ninja bodyguard of Sensei, Kuda Izuna made her coolest ninja pose as she prepared herself to face the threat to her master.

"…"

The third girl, Trinity's pink nurse Sumi Serina stayed silent and only showed a poker face smile as she exchanged the syringe attached to her rifle's underbarrel.

"Really~ I can't have a single day with Sensei without obstacles appearing. Well, today I came here to kick all of you annoyances out of Sensei's office so I guess that so many of you appeared is a rather good thing."

"The one who is being an annoyance is y- Nin!"

Before she could finish her sentence, Wakamo had already shot Izuna who had barely managed to avoid it with a sommersault. With the shot as the signal, the guns started to blaze. Izuna made use of all her acrobatics to distract Wakamo's aim. Serina pulled her body close to the ground and charged towards the intruder pointing the syringe at her. Noa finally moved her gaze from the notebook and started shooting in concentrated barrages.

With Noa shooting not to harm her directly but to cut off her movement and allow the other to engage from close, Wakamo decides to pick up the glove and also charges forward. Deciding the syringe with unknown contents to be the most dangerous, she lunges her rifle's bayonet at Serina only to strike a doll.

"What?!"

"Substitution Jutsu!"

Serina suddenly appears beside Wakamo putting all of her weight on stabbing with her syringe but just before it connects Wakamo puts her hand on her pocket.

*KABOOM* An explosion occurs on one of the rooms close to Schale's office. While the pressure wave and heat barely reach Serina, it distract her long enough so that Wakamo's spinning leg kick lands on her torso and sends her away, while a well placed shot on the chest after the twirl makes Izuna recoil a few steps back.

"Ufufu~ Seems like I will be able to have some fun while taking out the trash this time."

Wakamo tone shows the smile that her mask hides as the other three girls take the time to reload their guns.

"As expected of one of the Seven Prisoners, it's not going to be easy, is it?"

"My Substitution Jutsu is just one of my 108 secret ninja techniques. Allow me to show tou all of them. Nin nin!"

"A deranged woman like you can only become a health hazard for Sensei. Quietly allow yourself to be excised from his life."

With a tone ranging from playful to plain old scary, the three defenders of Schale answer the taunt and restart the fight.

Four explosions, uncountable broken windows and ten minutes later, the fight gets interrupted by a whistle.

"*fweet* Stop right there! This is the Public Safety Bureau! All hands up!"

Announcing herself energetically, Nakatsukasa Kirino breaks the fight along a Nemugaki Fubuki that only has enough energy to drag her weapon behind her.

"*gasp* Fubuki! Isn't that Wakamo?!"

Seeing one of the people responsible for the gunfight, Kirino shakes Fubuki's shoulder with an alarmed expression.

"…Nope. That's not Wakamo."

Surprised, Kirino asks her.

"Ah! Could it be you think it's one of her doubles. Like what happened in Valentine's?"

"No, there is no one who looks like Wakamo here."

With Kirino showing an expression of understanding absolutely nothing, Fubuki explains to her.

"If one of the famous Seven Prisoners was here we would have to contact our superiors, mobilize the entire Public Safety Bureau and while they're coming, us two would have to hold the ground against her. But if it's just some random students shooting and making things explode then it's just another day in Kivotos. Nothing we need to worry about."

Kirino forgets to even answer back from how dumbfounded she is. Fubuki takes the hand of the shocked police officer and says her goodbyes.

"We're going to go pick up some doughnuts. Don't be too naughty, ok?"

As Fubuki turns around and starts leading Kirino away another shout interrupts the scene.

"Wait officer! That girl is a thief!"

Shiroishi Utaha and Toyomi Kotori, head and member of Millennium's Engineering Department ride into the scene on top of Utaha's robot Rai-chan, although for Kotori, perhaps the expression holding on for dear life might be more correct than riding. Upon stopping, Utaha immediately finds the shotgun that Wakamo had used to open Schale's now mildly scorched door and picks it up, pointing and accusing finger towards the legendary delinquent.

"This woman stole our Skeleton Key prototype this morning! Arrest her immediately! Also, because she blew up her way into and out of Millennium, Yuuka is incredibly pissed and today is budget revision day. If our budget gets cut I want her to pay for it too!"

While Fubuki is busy trying to think up a way to throw these problem to someone else in the Public Safety Bureau, Izuna asks about what piques her curiosity.

"Skeleton key? What is that? Is it the key to a seal that hides evil forbidden ninja techniques?"

"Glad you asked! Kotori, your turn!"

Pushing off her chest in pride of the latest creation of the Engineering Department, Utaha throws the shotgun to a Kotori that has managed to calm herself. As if on cue, the floating sphere that had been on standby by Noa's side moves in front of Kotori and points its lens at her. Kotori then begins.

"Tired of forgetting your car's keys inside of it? Have you lost your house's key in the middle of one of the usual Kivotos gunfights? Well, be worried no more because Millennium Engineering Department has something that will wipe out all of your problems! We are honoured to present with, the Skeleton Key! A full auto 20-gauge shotgun with an automatic picklock! You won't lose the keys anymore because the shotgun will replace all of your keys! Just press the cleverly disguised button on the shotgun and the automatic picklock will appear! From the cheapest lock to the lock from the safest safe ever, our patented automatic picklock will adapt and open it for you! Make everyone think you're just carrying a shotgun while you're actually showing them your house's keys! What? You say you can't use it because your house uses an electronic lock? The why do you think you're carrying a full auto shotgun? Just open the door with unstoppable firepower! What if there is no door? The make your own door! It's a full auto 20-gauge shotgun for Kivoto's sake! Just spray this bad girl all over while drawing the shape of a door and BANG! You have a door! And this is not all! If you call now to the number appearing on screen in the next 2 hours, with your purchase of the Skeleton Key you will receive a second Skeleton Key! Yes you heard me right! A second Skeleton Key! Dualwield them to look like one of those action BlueRay badasses! Remember, this offer is only for the next 2 hours! Don't miss it!"

After letting out all the marketing spiel, Kotori finally stops to breath and the sphere moves towards Utaha letting out a sound through some hidden speaker.

"Aaand I've got it all. I'll upload it after editing as we had previously discussed."

Happy with the words spoken by the sphere, Utaha once again points at Wakamo and boldly proclaims.

"And that's why you Valkyrie Police Academy students should detain this person. The funds of our club on the short term depend on the Skeleton Key and that's why she shouldn't go unpunished after stealing it!"

Awaiting her answer, Utaha stares at Kirino who has had enough time to heal her shock and the police officer asks.

"Do you have the DO-38 Certificate?"

"Uh?"

It's Utaha's turn to be confused as she is met by a question she wasn't expecting from the Valkyrie student.

"Do you have the DO-38 Certificate?"

Kirino simply asks the same question again as Utaha starts racking her brain to see if she remembers anything about a DO-38 certificate.

"No, I don't remember any DO-38 certificate."

Utaha answers and looks at Kotori and Noa, who is skimming her notebook.

"Me neither, Utaha-senpai."

"My notebook doesn't have anything about the Enginnering Department asking Seminar for permission to obtain the DO-38 Certificate."

Hearing those answers, Kirino and Fubuki silently walk towards Utaha and Kotori, then both pull out handcuffs and put them on the wrists of the two Millennium students.

"Then under law 38-2022, we arrest you under the charges of making illegal tools without the authorised license."

"I'm sure that Millennium's Engineering Department has the right licenses for weapon making, but tools for criminal purposes like lockpicks are a different matter altogether. Damn, to think we would catch illegal tool makers today, do you think we'll earn a free day for this when we report it?"

Kirino and Fubuki start dragging Utaha and Kotori out of the scene, the first with a face showing the satisfaction of a job well done and the second with her head on the clouds fantasising about how much she is going to nap on her newfound holiday. Utaha and Kotori not only emulate but surpass Kirino's previous shock as they are obediently taken out of the scene with their mouths wide open. Utaha's robot, Rai-chan, obviously follows solemnly behind her master like a good law abiding robot.

Once the four girls and the robot leave the scene Wakamo aks.

"Well, now that the nuisance is over, shall we continue?"

The remaining girls in front of Schale's entrance prepare themselves to continue but the sphere drone takes the chance to cut in.

"Actually, Sensei is not here so is there any point to this fight?"

A third wave of surprise hits Schale's entrance as everyone stares at the robot.

"What did you just say, Hare?"

Noa asked for further explanation from the remote user of the drone and member of Veritas, the well known hacker club from Millennium, Omagari Hare.

"While Wakamo was planting the bombs and Noa, Izuna and Serina we're checking the building suspecting that someone had illegally broken through, Sensei rushed out of the building at full speed. It seems that Sensei received a Momotalk from Abydos because a student from there grab her bicycle and charge against a bank that was receiving an armoured van with dirty money from the Black Market and so the rest of the Abydos girls asked Sensei to provide assistance."

After a whole minute of just standing there, Izuna was the first to move. She entered Schale's office, checked that Sensei was indeed no there and went back to the other girls.

"Report! My lord is indeed not in the office!"

"Also, with all the racket we've done he would have come out to stop us if he was here."

Serina added.

"So Sensei ignored in order to go check on a bad girl? If it's about being a bad girl I've been terribly bad, why isn't he here to punish me?"

Taking her thoughts on a clearly bad direction, Wakamo pondered aloud, This thoughts were then surprisingly picked up by Noa.

"Maybe we aren't enough of a bad girl."

"What do you mean?"

Wakamo, not expecting to get an answer to her thoughts, asked by reflex.

"Maybe this Abydos girl has something that we don't have. Maybe it's a special drive, maybe it's a different thought process, an unknown variable. What if we recruited her help?"

"Recruit her help for what? On how to catch Sensei's attention?"

"On how to rob a bank."

The final wave of surprise of the day hit Schale's entrance.

"We will become the baddest girls in all of Kivotos and Sensei will have no choice but to always keep his eyes on us."

The girls took a moment to fully comprehend the bold statement from Seminar's secretary.

"It's so crazy it might work."

Concluded Serina, getting somewhat carried away by the mood.

"If we include people like Trinity's mysterious master criminal Faust, I think we have a chance at it. What do you think, shall the five of us here start the greatest bank robbing group that Kivotos has ever seen?"

"Eh? Me too?"

"Yes, you too, Hare."

Seeing the pressuring smile that Noa directed at the drone's camera, Hare abandoned the thought that just because she wasn't there physically she could wash her hands out of it.

At the moment nobody knew that this day would be written down in history as the day the most infamous delinquent group of Kivotos was born.

The day Kivotos Eleven was born.
