"They're coming."
A cool, clear voice.
Like jade beads falling onto a plate.
"What's coming?"
Chigusa, who was bending down to pick up a large magic stone, froze and looked up blankly.
But.
Before she could react.
"Shing-!"
-the sound of a blade leaving its sheath.
Almost at that same instant.
Onigawara Rin, who had just been wiping blood off her blade, Hanabishi Warabi, who was leaning beside a chest licking a lollipop, and even Nemumeno Satori, who seemed to be dozing.
The aura around them.

The killing intent that had just subsided erupted instantly, like a powder keg reignited.
There was no verbal exchange.
No orders were needed.

A dozen? Twenty?

"A Monster Party!"
"We're done for..."
Chigusa's legs went weak, and she nearly collapsed onto the ground.
With numbers like these.
Even an elite Lv.3 squad would probably have to turn around and run, wouldn't they?!
And yet.
The monsters' screams were more agonized than ever.
A Hellhound opened its bloody maw and bit down on Sasamori Aya's shoulder.
"Crack!"
But the sound wasn't that of bones breaking.
It was
