Part 1

July 20, 10:21 am

"Such misfortune."

Tsukuyomi Komoe just threatened Kamijou and Aogami Pierce with a Columbus's egg if they didn't stop talking. Not wanting to spend an entire day trying to balance an upside-down raw egg, Kamijou sighs as he stares out the window.

I wonder what she's doing now... I think she forgot her nun cap back in my room.

Kamijou sighs again as he remembers his encounter with the silver-haired sister earlier this morning.

After finding out that all of his food went bad due to the previous night's blackout, Kamijou decided to air out his futon, only to find a nun wearing a white habit hanging on his balcony.

He tried to feed the hungry nun with some of the rotten food that was in his freezer, only for his conscience to kick in. He jumped into hell by eating the hot "trash" by himself.

When things finally settled down, the silver-haired nun known as Index explained her predicament to Kamijou. She was running away from "magic societies" that are after her, jumping from building to building when she fell onto Kamijou's balcony.

Kamijou didn't believe in magic. He, however, believes in the existence of superpowers. Academy City boasts of 2 million and 300 thousand espers; there are people who can teleport, brainwash, and even manipulate electricity. With the Power Development Curriculum, even those without abilities will be able to at least bend a spoon.

Such abilities are commonplace in Academy City. Kamijou wouldn't have batted an eyelash if Index said she had a superpower. However, if there's something as convenient as magic, why would anyone want to develop abilities in the first place?

To prove her point, Index pointed out the robes she was wearing. The nun habit [Walking Church], that Index wore is supposed to be as resistant to damage as a nuclear bomb shelter. However, it unraveled like a gift ribbon after coming into contact with Kamijou's right hand.

Even though the nun says that the habit is made by magic, there's no way that he'd believe that magic exists that easily. However, it is certain that what she said isn't completely false.

But what was all that about? 103,000 grimoires... Where does she put all of that? She says she has them "right here"...

Index landed on Kamijou's balcony, being chased by "magic societies" for the 103,000 grimoires she possesses. She came and left Kamijou's life in a hurry, leaving only a white nun cap behind.

Maybe she'll come back to pick up what she forgot someday.

Part 2

July 20, 4:08 pm

Because of several sessions of See-Through Poker, even though it was just summer remedial classes, the remaining members of year 1 class 7 weren't let out until the normal dismissal time.

Kamijou rises from his seat, intending to get back home as he was rather tired from his lessons. After stretching his stiff limbs, Kamijou grabs his school bag and heads for the door.

Just when Kamijou reached for the sliding door's handle, the door opened and Kamijou was faced with the woman from Anti-Skill that came to their class yesterday.

"Oh, so you're finally done with remedial classes, huh? Then, let's get going."

Hearing the female voice, Kamijou shakes himself out of his stupor.

"Eh? What do you mean by that, sensei?"

"You can't go home yet. We have to go through your Judgment papers." Placing her hand on her waist, Yomikawa stares at Kamijou intently as if telling him not to waste any more of her time.

"That's today? But it's late already."

"And whose fault do you think that is? Since I've waited for your class to finish already, and I don't to want to let all the waiting go to waste, we'll go through the contracts today. All nine of them."

"...Such misfortune." Kamijou drops his head and sighs, and goes to follow the glamorous-looking woman to her car.

"Don't worry, I'll drop you off later to your dorm. I can't have you wandering the streets at night right after you joined Judgment."

Part 3

July 20, 4:57 pm

"Good afternoon." Kamijou and Yomikawa greet as they enter the 177th Judgment Branch Office.

Kamijou looks around the office in interest, not having the opportunity to do so two days ago after being dragged by a certain electromaster.

He could see several desks with computers on top of them; most were shut down. One of the computers is left on; its screensaver based on the armbands that Judgment members wear when they're on duty. After staring at the Judgment shield spinning lazily in the middle of the screen, Kamijou turned his eyes away and looked around the office once more. Aside from a few shelves, Kamijou could see several boxes labeled with the Branch Office's number from where he was standing.

Only one member is in the room, a certain short-haired high school student who is busy typing away on one of the only computers left on.

"Uhmmm... Konori-san... was it? Where are those people from the other day?" Kamijou asks, certainly not expecting to the office to be so quiet after the fiasco that happened two days ago.

"Ah... you mean Shirai-san and the others? Shirai-san went to gather some information about a case, while Uiharu-san left just a few minutes ago. We'll have to reintroduce you to everyone later, but for now we'll have to work on those documents." Konori says, closing the laptop lid. She stands up and gathers some papers from a nearby fax machine and leads them to the small sitting area.

"The first and most important thing we'll do today is to brief you on what Judgment does." Yomikawa says as she sits down on the couch. Konori sits down beside the Anti-Skill member, and motions for Kamijou to sit across them.

"Eh? Aside from catching delinquents, isn't it just a walking customer service system?" asks Kamijou as he puts down his school bag and sits on the couch opposite Yomikawa's.

"That's a good way to put it, although that's not all that Judgment does." says Yomikawa, taking the stack of papers from Konori and placing them on the coffee table in front of her.

"Judgment serves as Academy City's discipline committee. Keeping public order is Judgment's main concern, which is why Judgment helps out with a lot of various tasks around the city. Helping lost people, finding missing belongings, going on cleaning or traffic duty when the machines are out-of-order; these are some examples of what a Judgment member deals with on a regular basis."

"So? Are you intimidated yet?" Yomikawa asks Kamijou.

"Who would be?" Kamijou shrugs, not seeing what the big deal is. From Konori's explanation so far, Judgment's tasks don't seem to be much different from what he does every day.

"Anyway, let me continue. Since Judgment is mostly made up of espers, we also handle most of the esper-related incidents. We can arrest any criminals or delinquents, but they can only be detained by Anti-Skill. Judgment members often work closely with Anti-Skill on major cases. In case of emergencies, the members are also in charge of evacuating the civilians while Anti-Skill deals with the situation. They're technically our superiors, and we even receive training from them." Konori pauses at this, seemingly recalling something important.

"Which reminds me, Yomikawa-sensei? Normal Judgment members have to train for four months before they become official members. Doesn't he have to go through that before he can actually do his duties?"

"Don't worry. Since this guy's a special case, I managed to do something about that. If we finish his paperwork, he'll be able to start as a Judgment member as soon as possible." Yomikawa answers, pointing at the black-haired student across the table.

Kamijou cheers at this internally. He doesn't mind helping out people, but he surely doesn't want to spend his summer break doing some sort of training. His rejoicing is cut short when Yomikawa turns to face him.

"However, you still need to go through the training and pass the tests. It won't do to have you out there without even knowing how to use the necessary equipment or knowing what to do during emergencies."

"...Such misfortune." Kamijou sighs, resigning to his fate. He already expected this outcome, but it didn't stop him from hoping for his assumptions to be proven wrong.

"So? Where will I train? Who's gonna train me?"

"There are special training grounds reserved for Judgment and Anti-Skill use at District 2, so that's where you'll be going. Also, since I'm the one who roped you into Judgment, I'll have to take responsibility. Which means this won't be the last time we'll see each other. I don't want to bother the other members of Anti-Skill with something as trivial as your training, so I'm the one who's gonna be handling most of it. "

"What kind of training is it going to be?"

"Aside from hand-to-hand combat, you'll be having some first aid training. Of course, we'll also teach you how to handle law enforcement equipment, how to read maps, and other vital skills you might need in order to become a good Judgment member."

"So when do I start training?" asks Kamijou hesitantly, not sure if he wants to know how much of the precious summer vacation he'll have left.

"Well if we finish this today, we'll have you do some basic fitness tests tomorrow. Don't worry, we don't immediately run trainees to the ground on their first day!" Yomikawa says lightheartedly. The long-haired Anti-Skill member then grabs the topmost form on the stack and places it in front of Kamijou.

"We'll still have to schedule your training after we finish these papers, so get to work."

Part 4

July 20, 5:39 pm

Saten Ruiko is excited, for her dorm's electricity got restored a couple of minutes ago. As she boots up her computer, Saten recalls the events that happened two days ago.

Uiharu was targeted by the graviton bomber for being a Judgment member, and it was only due to Mikoto's friend that they were saved. With his right hand, he managed to protect those behind him, leaving them completely unscathed.

Exhausted from the graviton bombing incident, she went to sleep as soon as she got home, intending to post about Kamijou's legendary ability on the following day. However, Uiharu fell sick the day after, and a city-wide blackout occurred.

With the electricity restored and without anything to do, Saten immediately went online and logged into the Academy City Urban Legends message board. Her fingers moving frantically across the keyboard, Saten typed in a new comment and clicked 'Submit'.

RS : ID skgw764582

I saw Railgun fire her finishing move at a boy two days ago, and he managed to nullify it using his bare hand!

Comments started flooding in as soon as she commented. Apparently with loads of free time during summer vacation, a lot of bored urban legend fans are just lurking around the internet.

NRN : ID nndf722827

NO WAY! I'm so envious!

TMNR : ID welo846158

I'm not, I wouldn't want to get caught in the middle of that battle.

SN : ID ngtj000321

Maybe that nullifier guy's the one who manages to beat Railgun with one hand.

KT : ID tkwd004326

But I heard that the one who can beat Misaka-sama with one hand is a Level 0, so I highly doubt that it's the same person.

KSJ : ID hbtb420024

I agree, I don't think someone with that much nullifying ability would be just a Level 0.

SN : ID ngtj000321

Aside from the another Level 5, do you honestly think anyone else would stand a chance at beating her without a nullifying ability? She's ranked 3rd out of 2.3 million espers!

TDAP : ID takk902354

But why would someone with a nullifying ability be just a Level 0?

TMNR : ID welo846158

Maybe the databanks are inaccurate, after all. Recently a lot of people had shown powers higher than their recorded level, can that be the reason?

KT : ID tkwd004326

He's been legendary even before Level Upper came out, so I don't think that's the case.

RS : ID skgw764582

Actually it IS him. I heard the Railgun say that she's never won against him before...

TMNR : ID welo846158

Then... he's 2 legends in one? Whoa! That's amazing!

TMNR : ID welo846158

Then why isn't he a Level 5? He has an awesome ability and he can beat a Level 5, right?

SN : ID ngtj000321

If Railgun's never won against him, does that mean they fight often? I wonder if they know each other personally...

TDAP : ID takk902354

They obviously do, since I heard she's always challenging someone to fights recently.

NRN : ID nndf722827

Come to think of it, I saw her chasing someone around yesterday night before the blackout, maybe it's that guy!

The comments kept on flowing and Saten found herself hard-pressed to keep up. She grins and braces herself for an entire day of discussing her favorite urban legends.

Part 5

July 20, 10:43 pm

A nondescript car pulls over near an eight-story apartment building, and a certain spiky-haired student got off from the right side. Before the student could turn to leave, he sees the passenger seat window roll down and something green fly out of it. His right hand instinctively reaches out to catch the flying object.

"That's your Judgment armband. Wear it at all times unless you're in class, you're undercover, or you're off duty. Of course, even if you're off duty, you'll need to have it with you in case of emergencies. It's troublesome to replace, so don't lose it, got that?"

"Uhhh… Sure." Kamijou answers the long-haired teacher, still staring at the armband that he just caught.

"Then I'll be off. Go straight to your dorm and don't loiter around, okay?" Yomikawa drives off right after rolling up her window, and Kamijou watches her car go into the distance before heading towards his dormitory.

"Like hell I'd even go anywhere at this time of the night. Practically everything is closed already." mutters Kamijou to himself as he heads towards the elevator, stuffing the armband inside his pocket.

Kamijou already had his dorm keys out even before he got to his door. After the stressful day, he's just about ready to collapse onto his bed and fall asleep without changing. Kamijou locks the door before turning on the lights, and heads straight for his bed right after removing his shoes.

Ah that's right, she left this in my room, didn't she? Kamijou thinks as he spots the white nun cap on his bed. He grabs the nun cap and places it on top of a shelf.

Maybe she'll come back to pick it up someday.

Not realizing that he just used his right hand to move the nun cap, and that the last of the silver-haired nun's [Walking Church] just got destroyed by his [Imagine Breaker], Kamijou Touma lay down and drifted off to a peaceful slumber.

A/N:

I based the message board on the backdoor website that Uiharu accessed during the Railgun OVA.

RS : ID skgw764582

is basically

Initials : ID 4letterschoolacronymSTUDENTNO

RS = Ruiko Saten

skgw = Sakugawa (Middle School)

Saten's student number is made up, as well as the other people's initials and student numbers. Also I don't know what welo stands for; I just grabbed the one who trolled Kongou Mitsuko in the Railgun OVA. The other school initials were based on authentic Academy City schools.

As for some of the things people pointed out in their reviews...

The arcade coin is small and it weighs practically nothing, so the air it displaces isn't a lot. I don't think that it'll cause a shockwave large enough to destroy the Judgment Office. Not to mention Imagine Breaker also pretty much nullified the railgun instantly, and since Misaka was standing near Touma, the distance is really small.

I guess this chapter answers most of your questions. As for Misaka, she goes to the office practically every day, not to mention she helps out in the serious cases without having to do all the Judgment chores. I don't think there's any point in making her join Judgment.
