There was once a cloning program that used the cells of the #3 Level 5, Misaka Mikoto.
In terms of results, it was a failure. Unable to create the necessary specifications, it was ended. However, this cloning technique was used for another experiment, creating a mass number of clones.
The Sisters.
Last Order was the commander of the approximately ten thousand remaining Sisters, and Misaka Worst was created after that through the unorthodox Third Season project.
The massive brain that was formed by the electronic network of almost ten thousand brains formed the Misaka Network. The network linked all the information that the Sisters had, and the network also worked for a "certain purpose".
There was Last Order, who was created as a "human interference commander", and Misaka Worst, who had "evil thoughts and feelings" embedded in her for some "certain purpose".
Thus…
"Go buy something?"
Accelerator, who was lying on the sofa, asked in shock, and the female teacher in the sports jacket, Yomikawa Aiho, nodded her head.
"I don't care whether you came back from the battlefield or some other place; since you came back, you better start acting like a member of society and live on."
"So you're talking about doing such a boring thing?"
"Huh?" Yomikawa acted like she was confused and pondered for a while, before continuing. "In human society, the most painful thing is being unable to help others and not being needed by others, right?"
"Cheh!" Unable to say anything, Accelerator got up. "You don't have to come up with some twisted introduction to psychology, you damned teacher!"
"No way, I have no intention of going into life counseling. Basically, I'll settle any problems that appear with this iron fist of mine."
"So, what do I have to buy?"
"Food. Those that I circled in red on the list."
"…That kind of thing again. Doing this really doesn't match who I am."
"In that case, work hard and get used to it."
Spurred by Yomikawa, Accelerator reluctantly grabbed his crutch and stood up.
Thus, Last Order, who had gotten sick of the spaceship game (she had woken up after the nap to challenge Misaka Worst again), looked up at Accelerator.
"Misaka wants to go!! Misaka wants to go!! exclaims Misaka as Misaka wants to be your assistant since you'll feel uncomfortable being alone!!"
"You're so noisy!! Stop trying to predict the future!"
Aside from Last Order, who was shouting "Misaka wants to go, Misaka wants to go", Misaka Worst seemed to be a little edgy for some reason.
Actually, to her, there was another battle other than the computer battle.
It was a real battle.
It was mentioned before that Misaka Worst had a strong sense of ill-intent thoughts and feelings added from a "certain aspect" of the Misaka Network.
This could be expressed not only through anger and hatred.
But also jealousy.
She was envious of Yomikawa, who was always talking to Accelerator. She also wanted to go along.
Last Order's thoughts spread to all the Sisters. As there was an interference with the "certain aspect", it affected Misaka Worst as well.
Misaka Worst, who normally wouldn't take orders from the commander, Last Order, would inevitably be affected.
For that reason...
(…Uwaah!? I want to go. I want to go shopping!! Damn it, Accelerator's none of my business, but the network, the network's giving an unbearable emotional wavelength, Uuwwwwaaahhhhhhhhhhh!! Nononononononononononononononono—!!)
Misaka Worst tried her best to resist the surging force, but she was still unable to withstand it in the end.
The reason was that though she tried to draw that evil intention out, Misaka Worst still couldn't handle it.
A short-circuited Misaka Worst stood up, and rushed at Last Order who was tugging at Accelerator's pants, knocking her away.
"Misaka, Misaka, too! Misaka wants to go shopping together!!"
A few minutes later.
After getting a wallet from Yomikawa, Accelerator asked a very simple question to Misaka Worst, who was lost in her own thoughts:
"What the hell were you doing just earlier?"
"…Misaka doesn't understand it herself…"
