Even with her rifle, The Leo Vertex by the wall was too far for Sumi to reach.

She instead fired at the one approaching.

Her shot accurately hit what appeared to be its brain, making it stagger and
stopping its advance.

(I was able to stop its movement with a single hit… This really is a remarkable
power up!)

Sonoko charged at the immobilized enemy, and with her spear started hacking
away at its joints with extreme precision, cutting them into pieces.

—Waa~ This has become so sharp~

Sonoko was surprised by her new power as well.
