Akira opened the group photo album.
The very first image was a selfie taken by March 7th.
If his memory served him right, March 7th was a girl who absolutely loved taking photos.
And indeed—every picture looked great.
He saved it without hesitation.
Returning to the group chat interface, Akira suddenly remembered something and checked his own status panel.
[Human]: UnknownDoomsday Points: 3700
Three thousand seven hundred points.
Today alone, he had killed more than three thousand zombies.
This was the perfect opportunity to spin the roulette.
Akira opened the Doomsday Roulette.
The interface displayed a dizzying variety of abilities:
Sea Tiger Explosive Fist.Friendship-Breaking Fist.Sharingan.Fire Magic.Mystic Eyes of Death Perception.
There were also numerous items and artifacts:
Death Note.What If Phone Booth.Poké Ball.Holy Sword.
Abilities were ranked as C, B, A, S, SS, and SSS.
Previously, both his Physical Enhancement and Five-Thunder Divine Art – Eclipse Thunder Form were B-rank abilities.
"Please… let it be something high-tier this time."
With anticipation, Akira activated the roulette.
1000 Doomsday Points per spin.
The wheel began to rotate.
The pointer swept past ability after ability.
Mystic Eyes of Death Perception…Dragon Slayer Magic…Shrinking and Enlarging Lamp…
Under tense anticipation, the roulette slowed—
And finally stopped on a narrow segment.
[Congratulations! You have obtained an S-rank ability: Primal Stone — Vector Manipulation!]
"???"
The points were deducted instantly.
Akira was excited for only a moment before forcing himself to calm down.
Vector Manipulation…
He knew this ability well—from A Certain Magical Index.
Among ability users in Academy City, the strongest was Accelerator, the number one ranked esper, whose power was vector manipulation.
However, vector manipulation alone did not automatically guarantee overwhelming strength.
Accelerator's true advantage lay in his monstrous computational ability.
Even without fully understanding his own power, he could dominate simply by calculating and redirecting vectors.
There were many vector manipulators in Academy City.
But only Accelerator stood at the pinnacle.
Even before his brain injury, his computing power rivaled that of a particle computer.
Akira opened the ability description.
[S-Rank Primal Stone — Vector Manipulation]After fusion, the Primal Stone ability awakens, granting instinctive control over vectors.
"Primal Stone…!"
Akira's eyes widened.
If this were ordinary vector manipulation, he might have been disappointed.
He didn't consider his own computational ability particularly strong.
But Primal Stone was a completely different matter.
The concept of Primal Stones came from A Certain Magical Index.
Those born with abilities were known as natural-born espers.
In Academy City, nearly 99% of espers—Accelerator included—used abilities derived from Personal Reality, meaning their strength depended heavily on calculations.
Primal Stone users were different.
Unlike artificially developed espers, Primal Stone abilities did not require computation.
They were instinctive.
The power responded as naturally as moving one's own arm.
Think it, and it happens.
For example, an ordinary ability user would need complex calculations to change the direction of a force.
A Primal Stone user needed only a single thought:
"Change it."
Akira immediately took a screenshot.
He also spent 1000 points to upgrade the ability to Level 2.
Then, he posted the screenshot in the chat group.
Unknown:"I just rolled a new ability."
March 7th:"Hey!! Akira, how do you have enough points to spin the roulette?! It costs 1000! I only get a few dozen points per daily sign-in!"
Unknown:"Doomsday Points aren't limited to sign-ins. You can also earn them by interacting with and reducing Doomsday Factors."
Kisaragi Akira:"In my world, there's something called evil spirits. They're classified as Doomsday Factors. Killing one grants points."
Kisaragi Akira:"And the apocalyptic game I entered today—killing zombies there also rewarded Doomsday Points."
March 7th:"Ohhh… I get it. We didn't even know what the apocalypse was before!"
Exusiai:"Uh… does what I'm dealing with here involve Originium?"
Aqua:"Hmph! Then I'll just wipe out the Demon King's army—and the Demon King himself!"
Saeko Busujima:"I… don't really know what the apocalypse looks like in my world."
Unknown:"@Saeko Busujima, it might involve zombies. I can't be completely sure."
Saeko Busujima:"Oh? If it's zombies, then I should start preparing. Thank you, Akira-kun."
She trusted him completely.
Even though Akira himself admitted uncertainty.
March 7th:"Ummm… hey, Akira—what exactly does your S-rank ability do?"
Unknown:"It's exactly what it sounds like. Four words: manipulating vectors."
March 7th:"Manipulating vectors? I don't get it!"
Exusiai:"Hehe… yeah, me neither."
Aqua:"Hmph! Such an incomprehensible ability can't compare to my divine power!"
Unknown:"…"
Saeko Busujima:"…"
Damn it.
There were three idiots in this group now.
