Kohina Hiruko happily picked up the magic stones scattered across the ground and stored them inside her spatial equipment.
"Hehehe, Kohina's in first place now!"
"Today I'm definitely going to collect the most magic stones!"
She was clearly in a great mood—at this rate, she'd exceed today's quota with ease.
And it was precisely when she relaxed her guard—
Tina suddenly raised her weapon and fired at the wall beside Kohina.
Bang.
A wolf that had just finished forming and was about to pounce on Kohina was blown apart in an instant, collapsing into magic stones before it could even move.
The other girls jumped in surprise.
Even Riveria Ljos Alf and Ais Wallenstein were visibly shocked.
Their gazes locked onto the weapon in Tina's hands.
"What kind of weapon is that?"
"I can feel a magic power fluctuation…"
Riveria was stunned.
There was no doubt—she could sense magic flowing through it.
…That couldn't be right.
Was it something like a magic sword?
Hearing Riveria's question, Tina gently stroked her beloved rifle and explained cheerfully.
"This is the weapon Onii-chan prepared for me."
"I don't really know how it's made…"
"But its effective range goes up to five thousand meters."
"It's the best equipment for support fire."
"And its power is really strong, too."
She didn't mention the rest.
The weapon Izumi had created wasn't just powerful.
It also had automatic targeting and head-lock functionality.
As long as the target was a non-humanoid hostile entity, all Tina had to do was aim in its general direction—the shot would land.
It was practically a cheat-level sniper rifle.
For extermination, it was absurdly effective.
After hearing her explanation, both Riveria and Ais were left speechless.
Five thousand meters…?
Are you kidding me?
With a weapon like that, who even needs a mage anymore?
Riveria found herself at a complete loss for words.
If someone hid in the shadows and aimed at a mage with this thing, they'd be killed instantly—no time to react, no chance to counter.
At that moment, Izumi spoke up.
"In our world, weapons like that are considered standard issue."
"There are even more terrifying ones—single shots capable of erasing an entire city."
"What these girls are using are just individual combat weapons."
"It's only because magic and other supernatural powers exist that their impact seems reduced here."
Hearing that, Riveria and Ais finally understood.
Their curiosity toward Izumi's original world deepened, and they began asking questions as they walked.
Before long, Izumi, Ais, and Riveria were chatting while moving forward.
Meanwhile, the girls began coordinating with one another, engaging monsters continuously.
Enju Aihara, Kohina Hiruko, and Asaka Mibu took the vanguard.
Midori Fuse moved fluidly around the battlefield.
Tina provided constant rear support.
And Kisara Tendou stood to the side, calmly issuing commands.
After only a few floors, their teamwork had already become remarkably smooth.
Watching their combat, Ais and Riveria were genuinely shocked.
How long had it been?
And these girls were already fully adapted to Dungeon combat?
Their combat instincts were terrifying.
Izumi, on the other hand, wasn't surprised at all.
These girls were born for battle.
If not for the idiots in the Black Bullet world, that world never would have been reduced to cowering inside a cage.
The very saviors capable of fighting were treated as omens of disaster.
They deserved extinction.
Izumi pushed the thought aside as the group continued deeper.
Before they knew it, they had reached the Fourteenth Floor.
At this depth, the girls were clearly starting to struggle.
The monsters here were already on par with Stage Three Gastrea-class threats.
Thanks to their coordination, they weren't in immediate danger—but to be safe, Izumi decided to step in.
Before Riveria and Ais's astonished eyes, Izumi casually waved his hand.
Several Pseudo-Void Spears materialized out of thin air and instantly annihilated the monsters facing the girls.
Then came the truly shocking part.
The monsters pierced by Izumi didn't just collapse—
They dissolved into light.
And every single one of them dropped alchemical materials.
The absurd drop rate left two veteran Dungeon adventurers completely stunned.
"T-This… what kind of luck is this?"
"So many materials…"
Riveria felt genuinely envious.
Hearing her mutter, Izumi merely smiled.
Did you really think EX-rank Luck was a joke?
Izumi then turned to the girls.
"Alright. From now on, you'll operate within the first twelve floors."
"Once your levels go up, you can go deeper."
"If you push further with your current strength, it'll become dangerous."
The girls nodded obediently.
"Got it, Onii-chan!"
"No problem!"
"We'll be good!"
They trusted Izumi completely.
Whatever he told them to do, they would follow.
Riveria and Ais walked up beside Izumi, curiosity written all over their faces.
"So this is far enough for them?"
"We don't need to go deeper?"
Izumi shook his head.
"For them, this is enough. For us, going deeper isn't a problem."
"Let's head to the Seventeenth Floor."
"I'm pretty curious about the Floor Boss."
They'd come all this way—leaving without seeing it would be a waste.
The two exchanged glances, then nodded.
"That's fine."
"Let's continue."
"We'll handle the monsters ahead."
Ais was here to test her new weapons—and she hadn't even had the chance yet.
The group continued onward.
The girls organized their spoils as they walked, handing everything over to Izumi.
It wasn't a huge amount, but it was more than respectable.
As they went deeper, the girls watched Ais carve through monsters like vegetables, eyes shining with excitement.
"Ooooh! Ais-oneechan is so cool!"
Enju, in particular, was completely enthralled by Ais's elegant yet deadly fighting style.
The others also watched carefully, trying to memorize her movements.
Learning even a single trick would be invaluable to them.
Kisara Tendou, however, wasn't watching Ais.
Instead, she observed the surrounding terrain, quietly pulling out her notebook and recording the routes they took.
Even if they couldn't reach this depth yet, having the information ready would be invaluable later.
When Izumi noticed this, a faint smile appeared on his face.
With Kisara around, there really was nothing to worry about.
In the Dungeon, monsters weren't the only threat.
Other adventurers could be even more dangerous.
But with a mature, razor-sharp mind like Kisara's keeping watch—
Izumi didn't need to worry about that at all.
