"Isn't that... shit, I can't remember. Accelerator, Shiage, do you remember how that works?" Touma turned to Accelerator as he scratched his head. He was pretty sure he learnt it in class, but as Kamijou Touma is not a man who prides himself in getting good grades, it would mean less if he wasn't able to remember it at all. After all, it might be one of those memories he lost.

Shiage just shook his hands and looked away. "Don't ask me, I'm a dropout. Hell if I know."

Accelerator just sighed.

"It'll take a lengthy explanation I don't expect you to understand. However, if his explanation of it is just as you say, then he's bullshitting you girls."

Homura was shocked. "What?" Certainly, getting involved in the world of Puella Magi as soon as she was discharged from the hospital, and have been rewinding time over and over ever since she saw her best friend die before her just to find a way to save her... even with the magic she used to strengthen her body, she is far from what one would call a true prodigy.

Accelerator continued. "Who the fuck taught that little critter Physics anyway? Some sort of Hollywood alien? Anyway, I'll be brief and point out where he is wrong. That shit of a critter deserves to die in a fire for bringing up such a false teaching to you brats."

Meanwhile, elsewhere.

"I want to talk to you, Madoka."

"... So you're alive, huh." Madoka responded with a tone, akin to the gloomy darkness of her room only lit by the dim light from the window. From which the creature with a nature no one understood, came from.

"Did you make contracts with everyone only to see them turn into Witches?"

Kyuubey, with his usual seemingly emotionless expression, answered Madoka with an equally emotionless tone.

"Oh, don't misunderstand us. We don't have anything against humans at all. Even with everything the three men did – or rather, 'boys', if I'm not wrong – it's just that I, or possibly we, can't understand them at all; and neither they did in regards to our efforts."

"..."

"Well, anyway, it's just... the unfortunate circumstances that come about."

Madoka turned her eyes, albeit slowly, to Kyuubey.

"Circumstances?"

Kyuubey tilted his head, turning it to face Madoka.

"Everything is for the sole purpose of prolonging the races of the universe. Madoka, have you ever heard of 'Entropy?'"

"...?"

"To put it simply, the heat energy you lose from burning wood from a tree is not the same amount of energy as it took to grow the tree."

While heat is a form of energy and it is produced by that very process mentioned, you do NOT lose energy. Energy is converted into another form which can't be used by the same process that it is used for. With that said, the energy used to burn wood is not the same as the energy to grow a tree either. Anyway, if with that statement it implies you 'lose' more energy burning a tree than growing one, it's actually the other way round.

"There's a loss in the conversion of energy, and the energy in the universe is disappearing."

As what I've said earlier, we DON'T lose energy. The energy spent becomes less useful over time as it continues to be used. I wouldn't want to think what will happen to the universe if there's a law that states energy disappears as it is spent. It is like dividing a number with zero, you know.

"That's why we went out to find energy that wasn't bound by the laws of thermodynamics. Our scientists invented a technology that would convert the emotional output of intelligent beings into energy."

Now this is pure bullshit. As long as it involves energy, there's no such thing as 'energy sources that is not bound by the laws of thermodynamics.'

"By the way, our race has never had anything like feelings or emotion. But we found it in one alien race amongst the many in the universe – humans. Within each human lifetime, the amount of emotional energy created by each individual is impressive. Within your souls is the energy to surpass entropy."

"We found that the most production was from girls in their second stage of development, with the fluctuation of hope and despair. In the moment that the Soul Gem turns into a Grief Seed, immense amounts of energy are created."

Yet another bullshitting. We're talking about the fucking entropy of the universe here. To put it simply, no matter how impressive that 'emotional energy' is, if he really wants to counter the effects of entropy he will need an amount of energy more than that in order to reach a balance between the efforts his race did and the so-called effects of entropy in his context.

"Created energy?" Fuck this shit. As well as energy is indestructible, neither can they be created – in which in his case follows, then the amount of energy gained from that created "Grief Seed" will be in equilibrium as the work involved in creating it. You know what that means? If that energy is equal to the level required to rectify the entropy of the universe – the sheer concentration of energy released from the system, in which results of the production of a "Grief Seed" - will rip apart the fabric of space and time when it does.

In other words, it'll be the end of the world as we know it. There will be no Witches, you girls won't get to fight it, and worse of all is there'll be nothing.

"It's the job of the Incubators to retrieve that energy."

He should stop shitting already. With that energy he'll just be flattened to molecular levels before he can even try.

Enough talk. At this point, we all know what we should do now. Let's go, 'Hero.'

"... Are we disposable, then? Should we just die for you?"

Madoka murmured.

Kyuubey replied nonchalantly. "One day, humanity will leave Earth and join us. In the long run, doing this is something beneficial."

"Don't you dare try to fool me." Madoka said, this time with a higher tone.

"Because of that stupid reason, Mami-san died, and then Sayaka-chan got turned into that thing... Where's the benefit in this? This is going too far!"

"But you were the ones who agreed to work along with us, right?" Kyuubey chided in before Madoka could say another word.

"ONLY BECAUSE YOU TRICKED US INTO DOING IT!"

With words that seemed like a taunt, but with a voice that does not have any expression of emotion in it, Kyuubey answered her.

"To us, the phrase 'to trick' has no meaning. Why does your kind always put the blame on others when they misjudge and fail to realize things? Humanity's standards of wealth are so hard for us to understand. Right now there are 6.8 billion of you, increasing at a rate of 100 every second."

"Why do you get so upset when even a single one dies? If you believe such things, then you are our enemy. I only came to explain that. Looks like it was a waste of time. Well, of course, it would be... Madoka. One day, you'll become the world's most powerful Puella Magi. And then you will become the most powerful witch in history. When that happens, we will be able to harvest an incredible amount of energy. If you ever feel like dying for the sake of the universe, please let us know. We'll be waiting –"

Just as about the creature was about to finish saying his words, another voice no one knew where it came from, bellowed: "Are you done talking, Kyuubey?"

"What?" Kyuubey turned back towards the voice, only to find it was from the door.

"... Kamijou-san? … Everyone? What... what on Earth... and how...?" Madoka raised her head as soon she caught a glimpse of what looked like a group standing between her and the door to her room.

Touma, Accelerator and Homura were there. How did they enter the house, no one has any explanation.

Kyuubey just shook his head. "Really, now..."

"Kaname! Pardon us for the intrusion, but we really need to talk," Kamijou approached Madoka from behind Accelerator and Homura.

"U-uh?" Things were happening too quick, Madoka was too stunned to react.

"And what might the meaning of this be?" Kyuubey, seeming to be unaffected by the ongoing commotion, said.

Accelerator returned Kyuubey's glance with a glare and a menacing smirk. "It means you fail your Physics forever you third-rate science fiction-born alien," he replied. "Shiage."

"Kaname! Get down!" Kamijou said as he pushed her down to cover.

Within the few seconds from the moment Accelerator pulled a microphone closer to his mouth as if contacting someone from his position to give a signal, a gunshot was heard, and its bullet immediately shot through Kyuubey's head. It exploded from the sheer velocity and power the bullet carried.

"W-w-w-wha-?"

Madoka turned her head a bit from cover and her left eye caught the headless remains of the creature.

However, another Kyuubey appeared from the window, and began eating the corpse.

"Really now," he said, "suddenly turning up in someone else's house, and calling someone to take my head off with that gunshot... you already know it's useless, right?"

Accelerator and Homura approached him, both standing back-to-back, pointing their guns at him.

"That's nice," Accelerator, still smirking, said. "That means you are a perfect target practice dummy that can fix itself anew. This is so nice, not even Academy City has this. Keh heh heh heh." He then pushed the microphone nearer to his mouth again. "Not bad. Even for a Skill-Out, you sure got the eyes for this. You should really consider a job with Anti-Skill."

A voice from Accelerator's earpiece replied. "Shut up! We're more than just punks who dropped out of school, damn it!" the voice said.

"Kyuubey," Homura muttered. "I... no, WE need to talk."

As I promised somewhere earlier today, here's another shot. This time it's "Accelerator calls bullshit on Kyuubey's definition of entropy." Well, I'm not a Physics major, so I hope someone could correct me where I go wrong, and elaborate more on parts I missed.

And now I'll amend that the Indexverse dudes be called by their given names from this point onwards, not surnames (except Accelerator since he doesn't have any to being with) for the sake of ease.

And in case you were wondering, yes, I'm not doing this in chronological order according to the events in the original Madoka Magica series.
