Kaname Chidori and Sousuke Sagara from Full Metal Panic!

Two individuals dressed in costumes inspired by characters from the Full Metal Panic series, specifically Kaname Chidori and Sousuke Sagara. The woman on the left has long blue hair styled in a ponytail with loose strands framing her face, complemented by a white shirt adorned with a red bow tie and a blue skirt that extends to her knees. She is also wearing brown shoes. In contrast, the man on the right sports short black hair, a black leather jacket over a white shirt, and a pair of black pants. He holds a large gun in his left hand, while his right hand rests on the woman's shoulder. The background of the image appears to be an indoor setting, likely at a convention or event where cosplayers gather to showcase their creative interpretations of characters from various media franchises.
