I found this series interesting and also a bit shocking. I was surprised to find that this series was shown on TV in Japan considering the strong sexual content.
It's about a young boy named Yukinari who has been picked on all his life by girls and thus has developed an allergy to girls and women. If a girl comes close to or even touches him, he breaks out into hives. After a mishap with his one friend (who happens to be a girl), he get teleported to the parallel world of Seirin. There, Yukinari meets a cute and very sweet girl named Miharu. For some reason Miharu is the only girl that doesn't cause Yukinari to break out, and thus they quickly become friends. Unfortunately, Yukinari finds out that Seirin's population is 90% female. What could be worse for someone who is gynophobic? Well, when other women find out about Yukinari, they all fight to make him their husband. He eventually escapes back to Earth with his new friend Miharu, however his troubles have only just begun.
While there isn't much of a central story, this was still an decent situation comedy. I liked the characters for the most part, although they could get mean spirited at times which kind of put me off. The soundtrack was arranged very nicely and I enjoyed both the opening and closing tracks. Some of the silliness got to be a little excessive, but overall not bad.
Be warned though. This series has a lot of nudity and strong sexual situations. Although not pornographic, it does get strong enough to warrant an NC-17 in some episodes. Anyone who is looking for a mature rated anime comedy, Girls Bravo is a series to try out.
