The second image that I posted is one of the promo images for the anime Bakemonogatari featuring the female lead, Hitagi Senjogaha. Dunno for sure what's with all the kipple in her skirt, though. Anyhow, the second image that I posted was the original - the one with Homura and a bullet-hole-ridden Kyubei is the derivative.
ETA: In regards to weird uses of hammerspace and skirts... I'm pretty sure I saw an anime somewhere that had a character that kept a sword up her skirt.
