Asuna:Is it just me... or is that so-called "ordinary high school student" actually about as strong as the Railgun?
Future Holy Sword Wielder:It hasn't even been that long, and yet Shiraikawa-kun has already developed the Holy Sword's power to this level?
Aqua:@Normal High School Student You're definitely the hero I had my eyes on! The mission to save another world and defeat the Demon King—yeah, I'll leave that to you!
Bronze-ranked Adventurer: So this is Shirakawa-kun's true strength!
Mai Sakurajima: Holy Sword Wielder... is that the one in the group files?
Mistress of the Butterfly Estate: How can a face-slap come this quickly?! Even the livestream from the Dimensional Chat Group couldn't keep up with that speed!!
Mistress of the Butterfly Estate: Upper-rank demons... I bet he could take them out in a flash!

In a quiet corner of the Butterfly Estate, Shinobu Kocho stared at the ongoing livestream in the chat group, eyes wide with disbelief, a gulp stuck in her throat.
She had watched the last broadcast.
Back then, Shirakawa, who had just awakened as a Holy Sword Wielder, was already terrifyingly powerful. But it had only been three days since then.
Upper-rank demons probably wouldn't even get a chance to resist, would they...?
Reopening the chat group's file archive, she located the document titled Holy Sword Awakening Guide. Although it was far more difficult to learn than the Breathing Techniques, if she could somehow master it—
'It might be able to help big sister with a lot of things.'

「You've slain a Corpse. Gained 50 EXP.」
「You've slain a Corpse. Gained 50 EXP.」
「You've slain a Corpse. Gained 50 EXP.」
A flurry of EXP prompts flooded Shirakawa's vision. The pre-selected class of Arch-wizard had already jumped to Level 2.
The destruction caused by his basic attack alone…
Though it hadn't damaged the building's load-bearing structure, all the corridor-side walls of the classrooms had been blasted through. The scene was a mess.
The EXP gain was less than killing a basic goblin.
But that was expected.
Shiraikawa had predicted this. However, with the sheer volume of undead, leveling the Arch-wizard class was simply a matter of time.
He didn't even need to conserve mana for future fights.
Standing at the stairwell corner on a higher floor, he turned his gaze toward a silent Misaka Mikoto, and said casually, "Let's keep moving."
"..."
The sudden surge in power was beyond what Misaka had imagined. While this level of attack might not be too much for her under normal circumstances—
What truly shook her was the blinding speed. It meant that most attacks would be rendered ineffective before they could even connect.
If that was a result of the "Holy Sword Wielder" title...
Then no matter what—
No matter how difficult it is—
I need to master it!
Standing at the top of Academy City, Misaka Mikoto had realized through the Dimensional Chat Group—
Her power wasn't enough anymore.
Following the floor plan Saeko Busujima had provided via DM, Shirakawa and Mikoto headed toward the school infirmary.
There was no need for active mana projection skills.
With stats over ten times that of a grown man, wielding the Holy Sword "All Things of Creation," mowing down zombies was no different than slicing through butter.
And with Mikoto assisting as well...
These emotionless, pain-insensitive corpses barely qualified as combat practice.
The infirmary door was intact.
Knowing Saeko's capabilities well, Shirakawa wasn't particularly worried. He knocked lightly, speaking in a casual tone:
"Saeko Busujima, we've cleared the area."
"..."
Inside the infirmary, Saeko, who had been on constant alert, heard the approaching footsteps and her name called from outside.
She instantly understood.
It was the normal high school student from the Dimensional Chat Group—Railgun and her companion—come to fulfill the rescue request.
She had seen the battle in the livestream. She knew very well—both Shirakawa and Misaka Mikoto were otherworldly superhumans.
Their power was suffocating.
Sliding the infirmary door open, she looked at the clean-cut, handsome boy and the brown-haired girl in a JK uniform standing beside him.
"Thank you both very much."
"How should I address you?"
"Just Shirakawa is fine."
As he sized up Saeko, he found that compared to her anime portrayal, she was even more stunning in this world. Her long purple hair flowed to her waist, and she wore Fujimi Academy's uniform.
She was clearly a high schooler, yet every bit of her radiated a full-fledged mature charm.
In terms of looks and figure, she could easily rank among the top even in a multiverse setting. Glancing at the silent Misaka next to him, Shirakawa offered a smile:
"And this is Misaka Mikoto."
"Nice to meet you."
Mikoto offered a polite nod. Her goal in taking this mission was simple: to earn enough points to exchange for stat-boosting items.
At that moment, a third figure appeared.
Wearing a white lab coat over her uniform, her long golden hair draped over her shoulders, and carrying a somewhat ditzy aura—
Shizuka Marikawa approached to greet them as well.
There was no ignoring her presence.
Her tightly fitted uniform blouse showcased proportions that completely redefined Shiraikawa's understanding of anatomy.
With every step she took—
Newton's law of gravity was on full display.
Marikawa blinked as she studied Shirakawa and Mikoto's uniforms, tilting her head slightly. "Are you two from another school?"
"How's the situation outside?"
"Pretty bad."
The zombie virus had spread worldwide. The best solution for now was to stockpile supplies and secure a safe, defensible shelter.
Shiraikawa shook his head lightly.
Turning to Saeko, he proposed, "The school is crawling with zombies. Got any ideas for a good shelter?"
"..."
Saeko gave a small nod—her family's dojo was a strong candidate.
But before she could answer—
The door to the storage room across the hall suddenly opened, and a pink-haired girl in twin tails wearing the same Fujimi uniform stepped out.
She introduced herself promptly: "I'm Takagi Saya, second year. Busujima-senpai, if you're escaping the school—could you take me with you?"
"I know a safe place we can go!"
