sniper tackle

Like a laser pointer to help someone aim.
(A ranged...)
“Sniper?! Orsola!!”
Kamijou let go of his own luggage, pushed the idly standing Index to the ground, then
rushed toward Orsola’s chest. He tackled her down to the road.
There was a soft, metallic noise.
Then Kamijou felt a pain on his back, going in a line from right to left. Something was
scraping against his skin.
