Hajime vs Invis, Arifureta Vol 4

As always, Hajime didn’t miss. Two crimson streaks cut through the air, piercing through their intended targets. The air shimmered again, and another Chimera fizzled into view, its head blown apart, along with a Super Bulltaur, its heart shot clean through. Both monsters slumped to the ground, dead.
“H-How did he know...” The demon could no longer hide her surprise.
Hajime just scoffed. Even if they were completely invisible, they shifted the air around them, which caused slight vibrations along the ground. On top of that, Hajime could easily pick up on their gazes, and their auras, along with the flow of their mana and even their body temperature. To him, the monsters were no more than sitting ducks.
