Sparkling Generation Valkryie Yuuki

A faux-manga style project about a man who loves Shoujo anime, particularly Magical Girl series, and rents a DVD, which turns out to be magic and turns him into a Magical Girl (to both the surprise of him and the Animal Sidekick Type Thing Behind The Magic, as he was surprised a man would rent this). It's pretty amusing, though I preferred her earlier series The Jar (which I don't think is available online anymore, sadly, though she says she'll put it back up soon). And, as to be expected, there's some interesting gender stuff in this one.
