Never a Dull Moment in Academy City

"Hmm..."

Kazumi has been stareing at the fire-shaped fruit for 20 minutes straight now, the main reason being the two sides of her have conflicting opinions. Her "current" self is screaming at her to eat this fruit right this instant, however, her "past" self is suggesting to wait and eat a more powerful fruit later on.

"I can see where my past self is coming from, but I doubt there will be any other fruits that will have a 100% compatibility with me. Gotta take my esper ability into consideration here."

Of course, fruits such as pika pika no mi or goro goro no mi would be much better choices in hindsight, Kazumi have a feeling that her 100% compatibility with the flame flame fruit will make up that gap in pure destructive powers. With no heisitation in her mind now, she picks up the fruit and takes a small bite out of it.

She regretted her choice the very next moment, the devil fruit tasted so bad that she almost threw up. Kazumi swallowed the fruit with great difficulty.

"That...tasted disgusting!" She took out a small carton of chocolate milk and chugged it to wash the flavors off her tongue.

.

[The host has consumed a devil fruit with 100% compatibility rate.]

[Requirements met, fusing the devil fruit {Mera Mera no Mi} with {Pyrokinesis}.....]

[Fusion successful!]

[Calculating esper power level...]

[Result: Level 3 --> 5]

.

Her body is suddenly coated in a layer of flames, something she was never able to do according to her memories. Her pyrokinesis was originally only capable of conjuring single fireballs and change its trajectory after being launched towards its target. But now, it has become so much more than that. Elemental transformation, intangibility, explosive firepower, multi-cast, you name it!

"Kazumi" took over as a childish grin grew onto her face, she's dying to try out her new prowess

"I need a testing ground for my newfound power, and where else to look than the back alleys of Academy City?" She looks at the clock on the right side of her bed, its 8:30AM. "Well, its almost time for school anyways. Might as well make a stop by the alleys."

And thus, she packed her backpack and gets out of the girl's dorm. On her way to Tokiwadai, she purposely made a detour between the buildings. At first, it seems as if there aren't anyone around, but she was quickly surrounded by a group of delinquents.

"Hey girlie~ wanna have some fun with us?" The delinquent who is smoking a cigarette said

"We will even take you to class, but school might be over by then." Another one of them said, the others laughed at his remark.

"Misaka is right, there's never a dull moment in this place." Her whole body is now covered in a thin layer of flames as she goes for a round-house kick, sending one of the goons flying into the trash cans.

"A-an esper?1"

"Snap out of it! She can't beat all of us!"

The rest of them attacked her all at once. At the very last moment, she boosted herself upwards using a burst of flames under her feet and then used another burst to launch herself back down.

"This body is more flexible than I thought, perfect~" She thought to herself as she dropkicks another two goons, giving them concussions.

"Just a disclaimer, this is self defense~" Kazumi said playfully as she casually takes the delinquent's cigarette and smokes one using her ability as a lighter.

"Hold on a sec, this isn't even real cigarettes." The moment she takes a smoke, even the delinquents can feel her demeanor changing. Her eyes, which was once full of life, turned dull. Even her playful attitude went away completely as well. "How useless can you be?"

"W-well...I couldn't buy real cigarettes so I found the closest thing to it."

Kazumi looks at the packaging. It clearly stated that the cigarettes are are completely free of nicotine, tobacco and other toxins, they are candy-flavored fake cigarettes that are designed to help troubled teens quit smoking, even the smoke smells like candy. She spits out the cigar and crushed it beneath her feet.

Slightly annoyed, Kazumi intensified the flames coating her body and kicked the two remaining delinquents into the air using a front kick then knocks them back into the ground with an axe kick. It is evident at this point that she is stronger than before.

In order to survive in the dangerous parts of the urban areas, Kota, her previous life, had to practice some sort of self defense. It was pretty cliche, but an old man offered to train Kota in the most deadly version of Taekwondo after he bought him a bento from the convenience store.

Seeing the fear in their eyes, a barely visible smirk grew on her face.

"Don't worry, I won't hurt you too much "

To finish them off, she powered up a minature flame pillar that sent the delinquents flying. The unconscious delinquents were coincidentally made into a pile of bodies.

"Haa...what a let-down..."

Kazumi sat down on top of the pile of unconscious bodies and lighted another one of the nicotine-free cigarettes with her pinky finger.

"Well, I guess I should be thankful that those aren't real cigarettes." Kazumi thought to herself

A sound of electric shock goes off, she turns around and saw a few men on the ground with a brunette girl standing, wearing the same uniform as her. Kazumi looks at her while puffing out a cloud of smoke.

"Hoh? Isn't she..."

The brunette turned towards her and saw that she is in the same situation as her, the girls smiled at each other before another girl rushed into the scene holding some kind of badge

"Onee-sama~!"

.

{A few moments ago, with a certain brunette...}

Misaka Mikoto was casually enjoying a cold beverage, but a group of goons surrounded her/

"it looks like those guys are bothering her"

"You think we should call Judgement?"

.

The girl sighs as this wasn't the first time that she was in this exact situation.

"Here we go again, It really is never dull in this city."

.

A few moments later, the same goons are on the ground with a few scorch marks. Kuroko suddenly took a sharp right and showed her badge

"Halt in the name of judgement! We've been alerted to your activities! Come quietly or I will be forced to-...what happened here?"

"Oh hey, Kuroko."

"Onee-sama~!" (Should I use 'sissy' from the dub or 'onee-sama'?)

A few moments later...

"Seriously, how many times do I have to say it before you understand? Maintaining the safety of Academy City is the job for Judgement, not ordinary citizens! Are you listening to me?"

"I can't help it if I get there first, can I? I'm always done by the time you guys show up."

"You can't just beat up another student without authorization. The city directors get all twitchy when that happens!"

"Pfft!" Kazumi, who has reverted to "Kazumi"'s persona, simply giggles at their interaction.

"And you! Don't you know the danger of using such a volatile esper ability in public?!"

"Cut me some slack, will ya? It was in self defense after all~" She said carefreely

"Ha...what am I going to do with you two?"

Kuroko suddenly remembered something.

"Say, Himura-san"

"Hm?"

"It says on file that you are a level 3 pyrokinesist, however..." She pulls up a camera footage of Kazumi taking down the goons. "The power you exerted to take down those delinquents are clearly beyond that. Did you perhaps..."

"Hahaha~ who knows?"

"Ugh...fine! But remember, I have my eyes on you!"

.

[The system has assigned you a quest!]

[Quest name: The New Level 5]

[Description: Let the students of Tokiwadai witness the birth of a new level 5 esper. Show them your awesome powers!]

{Goal: Receive the evaluation of level 5 in the System Scan]

[Reward: A random logia or zoan type devil fruit]

.

The quest isn't something noteworthy, but she is eager to see the full extent of her devil fruit. The delinquents from before barely put up a fight.

.

[TIMESKIP]

The trio has arrived at Tokiwadai Middle School. Kazumi went through the schedules and saw that her examination will be taking place at the baseball stadium.

"I guess we split up here. Good luck on your examinations!" Kazumi said cheerfully

"Good luck? Do you even know who onee-sama is?"

"No, should I?" Kazumi tilted her head, pretending to not know who Misaka Mikoto is.

"She is the third ranked-" Misaka held Kuroko's mouth in place before she could introduce her as the "Railgun". Somehow, she is glad that someone within the school doesn't know who she is for once.

"Oh that's right. I haven't introduced myself, have I? I am Mikoto Misaka, it's a pleasure to meet you."

"I am Kazumi Himura, the pleasure is all mine~" They shook hands and went their separate ways.

.

Thanks to the previous owner's memories, Kazumi was easily able to find the baseball stadium. As she gets closer, she can barely hear the testing results of the cu

"Ah, it looks like the tests have already began without me." She thought to herself before entering the testing site, where she was greeted by a staff.

"Please show me your student ID card."

"Here you go~" Kazumi did as she was told, the staff then gave her a card that has the number "154" on it.

"Take a seat, step into the testing grounds only when your number has been called."

.

The number of pyrokinesists in Tokiwadai was more than she expected, they took up 2/3 of the stadium. By no coincidence, most of the girls either belongs to a sports team or are hot-headed junkies eager to show off their powers.

Kazumi changed into her gym uniform and took a seat at the front row to watch the others' evaluations. According to her memories, the evaluation for pyrokinesists consist of 2 phases:

.

1st phase: Power Output. The first phase is rather simple, you launch your most powerful fireball at a target. It will measure your fireball's temperature.

2nd phase: Speed and Accuracy. In this phase, there will be 50 moving targets scattered throughout the field. The objective is to hit as many targets as you can while maximizing your accuracy in the span of 3 minutes. The AI will measure how accurate you are, maximum distance of your flames,

.

The AI will calculate your results and assign your renewed esper level accordingly.

Just as Kazumi finishes reviewing the memories, another student was called to measure her esper ability. Her performance was even more underwhelming than Kazumi had initially thought. The girl was only about to conjure up a small fireball after 30 seconds, and the temperature was only 795°C

(Author here, let me give you a crash course on flame temperatures so no-one will be bitching in the comments. Deep red fire, the weakest fire, is about 600-800° Celsius. Next up is orange-yellow flames, which is around 1100-1200° celsius, (around Ace's level). White flames are hotter, measuring 1300°C to about 1500°C. And finally, blue flames ranges around 2500°C to 3000°C.)

Moving onto the second phase, she was able to land 5 out of the 6 shots she fired. It's pretty good considering she only had the opportunity to fire 6 shots in the span of 3 minutes.

{Recording initial shot speed at 22.86 meters per second. Rapid fire ability: 2 shots per minute. Average temperature: 795°C}

{Overall rating: Level 3}

.

{Number 154, please proceed to the testing grounds.}

After lots of level 3 ratings and 2 level 4's, it is finally Kazumi's turn. She cheerfully walks into the stadium with an excited smile. Not only does she get to show off in front of her fellow students, she also gets a random devil fruit out of it. Who wouldn't take this sweet deal?

After the staffs make sure the measuring device is working properly, they quickly evacuated the testing grounds and gave Kazumi the signal to begin the first phase. All eyes are now on her, though they weren't really expecting anything special.

"Hah...I barely improved since last year."

"Can't blame ya, the targets are pretty hard to hit."

"Why are our examinations so much harder than the rest? Us pyrokinesists are practically laughingstocks for the other departments- what the hell is going on?" Before the student could finish her monologue, all the students inside of the stadium felt an intense wave of heat washing over them.

When they looked at the source of that heat, they saw Kazumi's right hand surrounded by brilliant orange flames with a slight hint of white in the middle.

"I've been waiting all my life to say this line..."

She drew her fist back as the heat intensifies even more. One of the staffs presses a button on the control panels, fireproof glass rose up from under ground to protect students from the students from the upcoming blast of fire.

"HIKEN!"

A column of flames erupted from her fists as she punches forward, reducing the target to ashes and almost breaking the fireproof glass on the east wing. Even though the students weren't hit by the flames, they could still feel the intense residual heat from it. Lets just say the students sitting at the front row got some slight burns on their skin.

{Ahem! Initiate the second phase.}

50 underground hatches open as the targets rises onto the field and started to rotate around the field at high speeds, much faster compared to. the evaluations of other students.

"Looks like they cranked up the difficulty after observing my performance in phase 1. Oh well, it doesn't matter." Kazumi thought.

She positioned the fingers of her right hand into that of a gun and shot small blasts of fire at the speed of bullets. Some of them didn't land, but the sheer firing rate makes up for that. Eventually, she got bored and switched to carpet bombing.

She conjured up a giant fireball and launched it into the sky, confusing the staffs and the students. Soon enough, they understood her actions.

The giant fireball splits into countless tiny specks of firefly-like flames that explodes upon contact, knocking over the rest of the targets. On that note, Kazumi's system scan is officially over. It didn't even take her 3 minutes to hit all the targets

"Not only are her attacks absurdly powerful, she is creative with her abilities as well. There's no doubt about it, she will be..." A staff thought with a serious demeanor, "the 8th level 5 Esper."

The stadium fell silent as they wait for her results with much anticipation.

{Recording initial shot speed at 1109 meters per second. Rapid fire ability: 10 shots per second. Average temperature: 1207°C}

{Overall rating: Level 5}
