A Certain Regretful Dragon

the birth of kamijou touma

Where do I start?
One day, I found a nun in a white dress named Index hanging from my balcony, starving and claiming she was being hunted by magicians. Magic? Seriously? I thought it was a joke, but when I saw a crazy priest named Stiyl throwing fire and then a woman with a katana trying to kill me, I realized it was real.

But the real problem was yet to come...
The girl, Index, had 103,000 grimoires memorized in her head—something the Church couldn't allow to fall into the wrong hands. So, they tricked a magician into believing he had to erase Index's memories, or else her brain would stop functioning.

After getting beaten up, dispelling some magic, and using my power to break Index's curse, she was finally free and no longer needed to have her memories erased. But there was one problem... In the end, I lost all of my own memories.

I didn't even have time to process my amnesia before I was dragged into another problem. A girl named Himegami Aisa, with dark hair and a blank expression, was known as Deep Blood—someone capable of attracting and killing vampires. Vampires?! As if I didn't already have enough to deal with.

Apparently, a magician named Aureolus Izzard was using this girl to try and turn Index into a vampire. He was an alchemist with a power called Ars Magna, which allowed him to turn anything he said into reality. Do you think facing someone like that is easy? He just had to say, "Kamijou Touma is dead," and it would be over.

But then came the fun part. My Imagine Breaker, which resides in my right hand, completely nullifies any supernatural phenomenon. When Izzard started losing control, a dragon appeared from my arm. In the end, I managed to defeat him, but I kept wondering—what was that dragon?

If I thought I had seen it all, I was dead wrong. It all started when I met a girl who looked identical to Misaka Mikoto... but different. She seemed robotic, didn't speak properly, and referred to herself in the third person. I thought it was weird, but I let it go.

Then came the bombshell.
I discovered that multiple clones of Misaka existed, known as the Sisters, and they were being massacred in an experiment to create the world's first Level 6 Esper. And the candidate for this? A lunatic named Accelerator.

The real Misaka was trying to destroy all the laboratories on her own. But since she believed she couldn't stop the experiments, she decided to sacrifice herself to put an end to the slaughter. What a stupid idea. What kind of person throws their life away like that?

So, I did what anyone would do... I punched fate in the face and went after Accelerator.

After almost getting killed by Accelerator and being saved by Misaka and her clones, I prepared for the final showdown.

The battle between Kamijou Touma and Accelerator reached its climax. The air was heavy with tension, and the dark sky mirrored the intensity of their confrontation.
Touma, with his right hand capable of negating any supernatural power, faced off against the strongest Level 5 in the city—Accelerator, who controlled vectors with terrifying ease. Little did Touma know that this battle would change his life in ways he could never have imagined.

Accelerator

Accelerator held back from charging in. He needed to think about how to take down this piece of trash in front of him once and for all.

"Every time he hit me, it was with that hand, and he never used any other power," Accelerator thought. "All I have to do is stay out of reach of that hand... or maybe..."

Accelerator looked at the spiky-haired boy and began to smile—a terrifying smile that sent chills down both Kamijou Touma and Misaka, as well as her injured clone.
