Chaika

A white-haired anime girl in a maid-style outfit wields a large rifle, first shown in a close-up with hands outstretched, then in a wide shot charging forward, aiming and firing a purple beam at an enemy, followed by a close-up of her determined face as she fires, and finally a bright flash from the weapon's muzzle. The setting shifts from a dark, shadowy environment to a rocky outdoor area under a night sky.
