Kestrel was crouching in the corner, watching the intense fight between Ren and the huge 'mosquito.' This creature had a pointy mouth that could easily stab through the thick roof tiles.
Kestrel copied the stabbing motion with her finger. Suddenly, the flying monster felt a sharp pain in its head, like a needle, and fell from the sky, screeching. It tried to fly again, but Ren wouldn't let it. Using his special gun, Ren fired shots, each one leaving a long white trail, and kept the creature from getting back in the air.
The creature's legs, wings, head, and eyes were repeatedly torn open by the bullets. The injuries healed quickly, but another bullet would find a weak spot. Each shot seemed to know where the monster was going, and the monster was hit so much it rolled around on the ground, unable to fly.
Ren stepped back and kept shooting from the rooftop, without needing to get close.
