Black Lagoon

A female anime character with long dark hair is shown in a series of action poses, first holding a pistol with a close-up on her hand, then sitting and aiming a submachine gun, followed by a confident smile, dual-wielding pistols in a hallway, and aiming two pistols in a dark environment, concluding with a shot of her pleated skirt. The scenes transition between an outdoor setting with a blue sky and ocean and an indoor, artificially lit environment.
